This article presents and tests a method for prioritizing constructs in
ecodesign practices in the automotive industry The research objectives
were understanding how and why ecodesign emerges in industry and
how we can prioritize actions iin implementing it The research method
was the double case study The objects were a mid-sized manufacturer
of electronic parts and a chemical products manufacturer both
suppliers of automobile assemblers and pertaining to automotive
supply-chains For the research ecodesign was organized in a tree-like
structure with seven constructs materials product components
product and process characteristics use of energy products
distribution packaging and documentation and waste From the first
case we concluded that ecodesign emerges mainly for cost reduction
and secondly for agents pressures although companies may have little
capacity to manage it due to market constrains In the second case
with the aid of AHP we conclude that for two different chemical
products the priority in ecodesign implementation is the first construct
employed materials mainly raw-materials and logistic operations
related to supplying warehousing and feeding manufacture lines

2 Introduction
Public customers and legal pressures have grown related with environmental impact from
manufacturing activities As a consequence of this movement actions that can reduce
environmental impact of such activities have been more discussed in strategic forums
concerning manufacture Key factors contributing to such environmental impact include the
resource-intensive style of some activities and the ever-shorter life cycle of products and
processes (KAZAZIAN 2005 MAXWELL et al 2006) Environmental commentators
emphasize the need to weigh the environmental cost of manufactured products against the
functional income we gain from them (BORCHARDT et al 2009a)
According to Donaire (1999) manufacture usually reply to such pressures with (i) end-of-
pipe control installing devices that neutralize the environment impact without interfering in
the process (ii) on-line control redesigning products and processes to reduce environmental
pressures or (iii) adding to the company mission a high environmental performance
requirement usually based on a formal managerial structure Kopicki et al (1993) had used a
slightly different language (i) reactive actions when he company limits to remediate existing
problems (ii) proactive actions when it seeks to attempt valid normatives in the manufacturing
process and (iii) value-seeking actions when the company usually practice environmental-
friendly activities regarding design supply manufacture delivers and after-use recovery
According to Weenen (1995) in environmental management proactive or process-integrated
actions are preferable than end-of-pipe or reactive ones A sound possibility for are the EMS
(environmental management systems) which among other requirements demand control
actions on environment performance and impact assessment of products and processes
Another possibility is the introduction of techniques of ecodesign
Ecodesign seeks environmentally friendly solutions in product design and process
development It normally considers both economic and environmental aspects associated with
the entire life cycle of products Such concepts promote a reviewing of techniques of
conceptualization design and production of goods (BYGGETH et al 2007) and offer the
theoretical basis for implementing new policies on design of products and processes After
Fiksel (1996) ecodesign is a technique of product design in which the usual goals of the
project such as performance reliability and cost of manufacturing appear together with
environmental objectives such as reduction of environmental hazards reducing the use of
natural resources increase of energy efficiency and recycling It allows linking the functions
of the product with sustainability aspects reducing environmental impacts and increasing the
presence of eco-efficient products (KARLSSON and LUTTROPP 2006 MANZINI and
VEZZOLI 2005) After Vercarlsteren (2001) many companies consider the ecodesign in
preserving not only the environment but also competitiveness and public image related to the
business and market environmental requirements
Different requirements for ecodesign are proposed in literature Many regard materials
components processes and products characteristics use of energy storage and distribution
packaging and waste (WOLFGANG et al 2005 LUTTROPP and LAGERSTED 2006
FIKSEL 1996) We mean prioritizing resources and actions in practices of ecodesign
Supported by Hermann et al (2007) which speak on measurement of performance on
environmental aspects we find relevant identifying priorities or degree of importance of each

ecodesign construct for companies in a particular industry and the extent to which each
company meets every requirement on each construct We also find relevant understanding
how and why emerges in a company the need for involvement of people from product or
process design in dealing with environmental issues Such kind of involvement may be related
with the mission of the company or with pressures originated by customers and legal agents
So the research main objective was to understand and prioritize relevant aspects in ecodesign
practices in a specific industry the automotive industry Specific objective were (i) to
classify the various aspects concerning ecodesign in objective classes of factors named
constructs (ii) to highlight some of the key factors influencing the adoption and
implementation of ecodesign practices at manufacturing companies and (iii) to find
numerical priorities for the constructs The research question was how can be understood and
how to prioritize the various aspects embedded in ecodesign practices in manufacture
companies of the automotive industry The main research method was the case study First
we gathered information from literature and in focus group sessions with experts organized it
in a tree-like structure that appraise and organize aspects of ecodesign in constructs Second
we chose a mid-sized automotive electronics supplier for electronic parts By interviewing
managers we investigated how and why ecodesign is being incorporated into the design of its
manufactured products Finally we used this structure in a chemical components supplier for
automotive industry for prioritize constructs in two products and respective processes
The numerical assessment was made by companyrsquos managers mediated by researcher in
focus group sessions supported by the Analytic Hierarchy Process (AHP) The AHP method
is cited among others by Chen and Tong (2008) and by Berander (2007) as the method of
decision support most applied to problems of priority in development of products The
theoretical foundation of the AHP is found among others in Forman and Selly (2001) and
Saaty (1980) In this research the criterion for the acceptance of an assessment was adopted
from Saaty (1980) a consistency ratio of less than 010 (CR lt010) Consistency ratio is the
probability that the numerical structure representing managers preference about an issue came
from a random not rational process In the other hand if CR is sufficiently low we can
accept that the decision was taken in rational basis not random
The main contribution of this article is to provide a method for prioritize ecodesign actions in
a specific company The method was developed assuming that the application in other
industries is feasible The remaining of this article begins with some background on
ecodesign encompassing the benefits it offers and the barriers to its implementation research
methodology and findings discussion and contribution and conclusions and suggestions for
continuity Limitations of the research are those related with the method a single industry
and exclusive use of judgement not physical measurement of field variates in prioritization
3 Theoretical background ecodesign
The concept of ecodesign green design or life cycle design refers to the design of new
products and services by applying environmental concerns aiming at prevention of waste
emissions and other forms of environmental impacts along the entire life-cycle of the product
In ecodesign environmental considerations are integrated into product and process design
procedures (WEENEN 1995) Ecodesign has been defined as a concept that integrates
multifaceted aspects of design and environmental considerations into product development in
order to create sustainable solutions that satisfy human needs and desires Ecodesign formally
introduces environmental concerns in the new products development process of a company

(KARLSSON and LUTTROPP 2006) Ecodesign can also be defined as a proactive approach
of environmental management that aims to reduce the total environmental impact of products
and services along their entire life-cycle (PIGOSSO et al 2010)
The factors that motivate adoption of ecodesign are not limited to environmental benefits but
can include saving costs gaining competitive advantage and improving corporate image
(VERCALSTEREN 2001) Some components systems or sub-systems can easily be
recycled reused or remanufactured which is an effective way to reduce both environmental
impacts and costs of the manufacturing processes (PIGOSSO et al 2010) Kazazian (2005)
tells us about eco-conception an approach that considers in conception stage environment
concern as important as factors such as technical feasibility cost control and market demand
Boks (2006) stresses the importance of product designers emphasizing their unique position
and ability to influence environmental strategies Designers can have a key impact when they
enlarge the focus of their efforts giving the environment a prominent position in defining the
parameters of product development However ecodesign tools can present difficulties for
companies Using then can require a high degree of expertise To make ecodesign tools more
useful and accessible we need to help designers link them to more conventional product
development tools (LE POCHAT et al 2007 RAO 2004 LOFTHOUSE 2006)
Despite the amount of tools available ecodesign is not always readily adopted by
manufacturing companies Authors note that industry designers often find the tools difficult to
use (LOFTHOUSE 2006 LE POCHAT et al 2007 LUTTROPP and LAGERSTEDT 2006
BYGGETH and HOCHSCHORNER 2006 BYGGETH et al 2007) According to Lofthouse
(2006) tools often fail to be adopted ldquobecause they do not focus on design but instead are
aimed at strategic management or retrospective analysis of existing productsrdquo The author
notes that what designers actually need is specific information on areas such as materials and
construction techniques The environmental information associated with ecodesign tools is
often very general In most instances the tools do not provide the detailed and specific
information that designers find necessary when working on design projects
Regarding the potential of a company for the application of ecodesign the organization must
assess factors regarding the company (internal) the environment (external) and the product
itself As internal factors we mention (i) motivation of management (ii) position in the
industry which tell us about the companys capacity to influence the specifications of the
product (iii) competitiveness since the leader is more likely to redesign products and (iv) the
industry dynamics which can provide learning and benchmarking for well-succeeded
initiatives Regarding to external factors we mean (i) legal regulation (ii) pressure from
customers and market and (iii) suppliers and partners since in automotive industry they are
essential in manufacturing strategy (VERCALSTEREN 2001) Regarding to the product we
mention that it must be conceived in such a fashion that it can easily be redesigned or at least
disassembled after primary use (BORCHARDT et al 2009b)
Fiksel (1996) proposed a set of practices related to ecodesign (i) to choose low impact raw-
materials preventing from those that can not be recycled or reused (ii) to focus on simplicity
using simpler forms and less quantity of material with replaceable parts and easy repair (iii)
to ensure acceptable amount of hazardous substances (iv) to reduce the use of energy in all
the product life-cycle (v) to use renewable energy (vi) to develop multifunctional products
with sequential functions (after a prior usage the product still is usable in a second way) (vii)
to extend lifetime (viii) to recover packaging or use refilling and (ix) to reduce risks and
works in disassembling tasks Wolfgang et al (2005) proposed for manufactured products

essential requirements that greatly emphasize on eliminating losses in production processes
Luttropp and Lagersted (2006) suggested two operational aspects surface treatment against
dust and corrosion increasing lifetime and easy assembly and disassembly using fixation by
screws or plugs avoiding welding connections
Regarding the factors that can influence implementation of ecodesign practices Boks (2006)
states that the main success factors are related to business aspects such as customization
organization and communication about the project After the author the most serious
obstacles are associated with social and institutional issues such as differences in vision
between managers organizational complexity and lack of internal cooperation Bahmed et al
(2005) state that important success factors are group and management motivation use of
work teams and a standard mechanism for product design providing training and having the
assistance of experts in eco-conception The authors also point out risks factors lack of
specific knowledge lack of understanding regarding the impact of ecodesign on areas such as
regulation cost reduction competitive advantage and organizational image improvement
lack of consensus about how to evaluate products in environmental terms lack of relevant
standards and the belief that environmental goals are necessarily at odds with economic
objectives Boks (2006) notes some factors that can accelerate decision-making on ecodesign
(i) pressure from external sources including legal requirements (ii) economic issues like
partners in the value chain (iii) consumer perceptions and (iv) relevant new technologies
Regulation can play an important role in promoting ecodesign Much of the relevant literature
we reviewed concentrated on regulation in the European Union (EU) which has implemented
some important environmental regulatory directives affecting the automotive and electronics
industries These include the end-of-life vehicles (ELV) directive the waste electrical and
electronic equipment (WEEE) directive and the restriction of hazardous substances (RoHS)
directive In addition the EU has finalized a framework directive for reducing the
environmental impacts of energy-using products through ecodesign (PARK and TAHARA
2008 LE POCHAT et al 2007)
4 Assessing Ecodesign a multicriterial problem
Ecodesign practices is intrinsically a complex abstract object which can be described as a
complex hierarchical system We proposed a method for modeling such complex abstract
objects We have structured hierarchically components in a triple-level structure in order to
describe the object Table 1 shows a number of ecodesign principles and practices that are
applicable in manufacturing in a tree-like structure format suitable for further modeling

The top term the theoretical object is explained by latent constructs based on concepts
explained by indicators performing a tree-like structure in a hierarchical fashion of levels
The structure was built in previous research (BORCHARDT et al 2009b) and was built in
group sessions with scholars and praticants in environmental management and product
development mediated by researchers The leading edge was the works of Fiksel (1996)
Venzke (2002) Luttropp and Lagersted (2006) and Wolfgang et al (2005) The list is not
exhaustive nor definitive since ecodesign is a dynamic field that is constantly evolving as
knowledge and technology develop and circumstances change
As the list suggests the scope of ecodesign is broad and multicriterial embracing product
design impact of raw-material extraction energy consumption industrial waste generation
and disposal and the full range of environmental impacts created throughout the entire life
cycle of products Such multicriteriality suggests using methods like AHP
The AHP (analytic hierarchic process) is well suited to prioritize constructs of a complex
object like ecodesign practices Wind and Saaty (1980) proposed that the AHP represents an
efficient method of dealing with complexity identifying and prioritizing the major
components in which we can structure a complex problem The AHP describes a complex
problem in a hierarchy in which each element of a level is further deconstructed into
subelements and so on until at the lowest representative level Once the hierarchy is defined
its elements are pair-wised compared by the scale [equal importance = 1 a little bit more
important = 3 more important = 5 much more important =7 dominant = 9] Intermediate
values can be used in intermediate graduations Pair-wise comparison produces a preference
matrix A in which aij is the relative importance of the i-th factor with respect to the j-th
factor For n factors we need n(n-1)2 judgments all above the diagonal Below we assigned
the reciprocals values like in (1) (SAATY 1980)

We calculate priorities by finding autovectors with maximum autovalues of matrix A Let A
be the comparison matrix (1) We must find the priorities vector w that satisfies (2)
Components of w are the priorities of the factors (SAATY 1980)
Aw = maxw (2)
By (3) we calculate CR the consistency ratio the probability that the matrix had been
originated by random not rational judgement RI is the average random index obtained by
computer simulation experimentation and given in Table 2
CR = [max ndash n][ RI(n-1)] (3)

RI 0 0 058 09 112 124 132 141 145 149
If CR lt 10 the judgments can be considered satisfactory otherwise should be reviewed and
improved For instance if someone judges a1 one and a half times more important than a2 and
a2 two times more important than a3 than he or she must consider a1 three times more
important than a3 If the judgment differs there is some inconsistency appraised by CR
(SAATY 1980) Anyway Hogart (1988) advise that we must count on some inconsistency in
mental models of deciders which must be reflected by the CR
5 Research
The research question was how can be understood and how to prioritize the various aspects
embedded in ecodesign practices in manufacture companies of the automotive industry The
answer must improve refute or correct the test hypotheses the presented method The main
objective of research was to test a method for prioritizing constructs in ecodesign practices in
an industry for the sake of reformulate strategic plans reinforcing practices judged more
important and eventually removing resources from those of less importance Secondary
objectives were (i) understand the emergence and practical implications of ecodesign
constructs in the industry and (ii) to distribute the relative weights (100 percentage points)
among the constructs A third objective is left for continuity (iii) to assess categorically the
actual situation of the constructs compare with priority and propose plans for those who have
biggest gaps between priority and performance The main contribution of the research is the
specific description of the case that added to others in growing depth and diversity may
expose regularities about the method and refine it
For questions containing the word how Yin (2009) indicates the case study method Case
studies can contribute exposing regularities that might be useful in formulating a theory about
the object (ECKSTEIN 1975) Repeated cases with similarities can contribute to the building
of a grounded theory (EISENHARDT 1989) Case studies in operations management are
acknowledged as a valid method for exploratory research like this (VOSS et al 2002) The
method aligns with the design research logic as stated by Hevner et al (2004) and Manson
(2006) According to this logic a method like we proposed can be thought of as a result of a
design process like producing a software package or a physical or logical artifact After a
mental or theoretical phase arises an idea that must be checked for viability and refined for
reliability in field cases (MARCH and SMITH 2005) like those here presented The authors
stress in the design research logic there are two important moments in the research the
mental or logical construction of the artifact and its refinement by field cases
51 Previous case understanding ecodesign in the automotive industry
The case took place in a mid-sized manufacturer with consolidated tradition in environmental
management and certified by both ISO 90012000 and ISO 140012004 normalization The
company produces on-board electronic components for vehicles The main research technique
was direct observation as well as interviewing the body of managers They began telling about
ecodesign in the industry as a hole and then about particularities of the company

The automotive industry operates in a highly competitive market with worldwide sale and
distribution The tolerance for product flaws is low especially in the case of vehicle safety
These factors can operate as constraints on the adoption of ecodesign practices by companies
in the industry Regarding natural resources the environmental balance for vehicles is
negative Production requires in raw material about ten times the weight of the car and uses
large amounts of water About forty thousand liters of water are required to manufacture a car
Vehicles consume fuel and lubricating oils most often from non-renewable fossil-based
resources sometimes returning as contaminants In addition cars use tires barely recycled
Moreover vehicles emit significant quantities of air pollutants including carbon dioxide (a
major greenhouse gas) and sulfur dioxide (which contributes to acid rain) Vehicles can also
be difficult to recycle at the end of their useful life They typically contain a variety of
different materials (including plastics and metals as well as electrical and electronic
components) that may be costly and challenging to separate
These impacts reinforce the perception that vehicles are not designed with an emphasis on
preserving the environment and promoting sustainability Partly in response to these concerns
the industry has developed high-performance and hybrid engines running on renewable bio-
fuels and using high-durability synthetic lubricating oils as well as has began using more
parts manufactured with recycled composite materials The industry is also seeking to restrict
the use of hazardous substances and to increase the quantity of returnable packaging and
materials These issues are particularly relevant in the European Union The EUrsquos RoHS
directive had banned the use of certain hazardous materials as constituents in specified parts
Regarding the company as its products involve special safety and security features it is not
allowed to reuse parts that could compromise reliability However raw materials such as
plastics and metals can be recycled The company has developed a complex business-to-
business relationship with its customers The company must meet applicable regulatory
requirements and also depends on customersrsquo approval in order to make changes to its
products When automotive assemblers qualify suppliers they primarily evaluate
characteristics such as reliability of deliver and products performance Suppliers also must
meet all relevant environmental requirements such as those related to restrictions on the use
of hazardous substances However exceeding minimal requirements does not constitute a
preferential or does not construct a competitive advantage factor for a given supplier So the
company has little autonomy in decisions involving introducing ecodesign practices in the
products and has little external compensation in doing so Prices politics are not influenced by
ecodesign practices in the automotive market at least until now
In spite of this the company addressed key issues regarding the environmental management
policy including energy and materials consumption and waste handling and treatment The
main drivers for ecodesign adoption was cost reduction due to dematerializing directives
(using the smallest possible amount of raw material) and to lowering expenditures related to
the treatment of waste The company formed a multidisciplinary group to handle the study
planning and strategic deployment of ecodesign techniques Top management organized a
working group that included people with expertise in relevant areas such as development
trade quality logistics and industrialization The group focused on activities related to the
development of products and processes implementing guidelines that included checklists for
design activities and product life-cycle assessment A huge difficulty was the shortage of
technical information available on environmental impacts of materials Using of standardized
databases is an alternative that the company now studies

Although the results are not yet those planned the body of managers recognized some
positive achievements costs reductions from dematerialization less manufactured products
due to multifunctionality implicating in less items in stock less test sets in the assembly line
less variety in the sales portfolio and higher lots of raw-materials purchased from a lower
number of suppliers reduction in costs due to waste disposal and transportation of raw-
materials
52 Next case prioritizing ecodesign in a company
The next case was developed in a chemical stuff manufactures that supply adhesives paints
greases and various liquid products to the automotive industry The company has several
families of products manufactured in multiple assembly lines and sites Design activities are
organized in teams with different requirements and practices Scarcely a technical
development or advance in one family of product can be extended to others but managerial
advances can be exchanged between groups Anyway due to the sharp differences between
design practices we chose two lines A and B to study Others can be addressed in the
continuity of the research
In focus groups sessions five experts in design for each family of product mediated by
researcher distributing relative weights among the constructs of ecodesign The prioritization
was made with the aid of the AHP In the first rounds calculated CR were nor proper so
researcher oriented experts to review flaws judgements until preference matrixes based on
more rational choices were achieved Experts produced the judgement matrixes of Tables 3
and 4 For the sake of clarity although the judgement did not employ this format we show
the preference matrixes with reorganized rows in decreasing order of importance As a clue
for checking out rationality in the preferences departing from the diagonal to the right side of
the matrix along the line one must find only increasing or at least equal numbers in
sequence If we find a decreasing number that means a flaw or incoherence in judgement

For the product A the most important construct in ecodesign is materials In fact due to its
chemical nature extraction warehousing and transportation of large quantities of A can
greatly affect quarries and its proximity and neighborhood of the manufacturer sites Using
alternate materials should be addressed in further redesign actions although experts stressed

11
they have little flexibility to change or use new materials due to consolidated technology and
assembly lines facilities For almost the same reasons the second construct in importance is
waste Due to the fact that half-life of the product is short and customers use little amount at a
time is not unusual that large amounts of the product must be discarded by end of usable life
This particularity turns wasting a problematic construct that must be focused in further actions
of redesign The third and fourth constructs are distribution and packaging with similar
priorities We stress that the distribution function includes not only the logistic operations of
transportation inspection and warehousing but also financial operations like assurance of
loads and people safety Packaging has still a significant importance due to the vast amount of
cardboard and wrapping plastic required most of them by no means easy for recycling or
reusing Components characteristics and energy usage have little priorities (lower than 10)
due to the particularities of the product and the manufacture process It requires no special
sub-systems to be assembled in the process is quite simple in little customized quantities and
exothermic what means that a part of the energy spent in it can be recovered and used
elsewhere in the site
Regarding to the judgement it was necessary more than one round but at the end experts
achieved a preference matrix with a very low inconsistency less than 1 meaning a
doubtless rational choice

For the product B as well as in A the most important construct in ecodesign is materials The
production is in bulk big lots but it is customized what means that the material leaves the
site with an assigned destination Exactly as with A due to chemical nature of the product
dependent of natural resources extraction warehousing and transportation can greatly affect
quarries and proximity of such installations and neighborhood of the manufacturer sites In
the same way using alternate materials should be addressed in further redesign actions Due
to similarities between the two products it can be worthwhile addressing unified actions
linking both products mainly regarding logistic operations Different from A the second
construct in importance for B is characteristics of product and process Process is quite

importance usage of energy Distribution and packaging have similar particularities but
distribution is a little bit more demanding due to warehousing and inspections activities
required by the nature of the logistic operation Different from A waste has little importance
due mainly to the fact that almost always the total amount of the product is consumed in
automotive assemblers Half-life of the product is very long and just-in-time practices
required by assemblers do not allow over-production what assures little problems regarding
final disposals of wastings Regarding to residues well-succeeded experiments conducted in
thermal sites assure an environmental friendly destination contributing to energy generation
for further processes As well as in A no special sub-systems are required to be assembled in
so components are by no means a problem for designers
As in the product A the judgement required more than one round but at the end experts
achieved a preference matrix with a very low inconsistency less than 2 as well as the first
case meaning a doubtless rational choice
Figure 1 presents a graphical comparison between the two products We remark that materials
are the most priority construct in both products Although the teams were formed to work
separately in this case due to the importance of the construct and the similarities of the flaws
unified actions could be planned in order to reduce environmental pressures due to the
handling of materials mainly raw-materials

6 Final remarks
The main purpose of this article was to present a method for prioritizing constructs that
explains ecodesign practices in automotive industry Secondarily the article aimed at
understanding central aspects of ecodesign implementation and practical implications of
ecodesign in the industry and to distribute the relative weights (100 percentage points) among
the constructs in order to reach a prioritization structure A third objective was left for
continuity to assess the situation of the constructs and propose plans for those who have

biggest gaps between priority and performance The research method was the case study First
objective was achieved in a mid-sized supplier of electronic parts The second was achieved
in a chemical manufactures by analyzing two different families of products Due to the
method the main contribution of the research was the specific description of the cases and a
practical application of the prioritization method We stress that with the achievement of the
third objective a company should address the constructs with bigger gaps (the difference
between prioritization and performance) rather than those of higher prioritization
The method combined qualitative research techniques such as focus groups sessions with the
mathematical calculations used to find the vectors of priorities from the preference matrix It
was a limitation of the article the use of assessment based in expertsrsquo judgments opposite to
measurements based in physic conditions from field variates and mathematic models When
physic measurements are used further statistic considerations are necessary once usually the
measured variates are random In the other hand objectives measurement like those provided
by physical variates hold less subjectivity then categorical judgements
As continuity we propose the use of other multicriterial method beyond AHP It is also
suggested to test the method in another industry We also suggest assessment of performance
of the product in the constructs by means of a set of indicators that can explain the construct
So the reformulated actions would focus not necessarily in the most prioritized constructs
but in the constructs with larger gaps between priority and performance The method can also
be applied in the entire or at least a bigger part of the automotive chain The application
along the chain can identify the fragile parts on the ecodesign development and helps to focus
efforts in the chain At last it is proposed to integrate the method to the cleaner production
technologies and reversal logistic models available in literature It is understood that the
method might indicate the ecodesign gaps of a product operation and offer enough support to
the implementation and maintenance of cleaner production and reversal logistics programs in
manufacture in an on-going improvement basis

2 Introduction
Public customers and legal pressures have grown related with environmental impact from
manufacturing activities As a consequence of this movement actions that can reduce
environmental impact of such activities have been more discussed in strategic forums
concerning manufacture Key factors contributing to such environmental impact include the
resource-intensive style of some activities and the ever-shorter life cycle of products and
processes (KAZAZIAN 2005 MAXWELL et al 2006) Environmental commentators
emphasize the need to weigh the environmental cost of manufactured products against the
functional income we gain from them (BORCHARDT et al 2009a)
According to Donaire (1999) manufacture usually reply to such pressures with (i) end-of-
pipe control installing devices that neutralize the environment impact without interfering in
the process (ii) on-line control redesigning products and processes to reduce environmental
pressures or (iii) adding to the company mission a high environmental performance
requirement usually based on a formal managerial structure Kopicki et al (1993) had used a
slightly different language (i) reactive actions when he company limits to remediate existing
problems (ii) proactive actions when it seeks to attempt valid normatives in the manufacturing
process and (iii) value-seeking actions when the company usually practice environmental-
friendly activities regarding design supply manufacture delivers and after-use recovery
According to Weenen (1995) in environmental management proactive or process-integrated
actions are preferable than end-of-pipe or reactive ones A sound possibility for are the EMS
(environmental management systems) which among other requirements demand control
actions on environment performance and impact assessment of products and processes
Another possibility is the introduction of techniques of ecodesign
Ecodesign seeks environmentally friendly solutions in product design and process
development It normally considers both economic and environmental aspects associated with
the entire life cycle of products Such concepts promote a reviewing of techniques of
conceptualization design and production of goods (BYGGETH et al 2007) and offer the
theoretical basis for implementing new policies on design of products and processes After
Fiksel (1996) ecodesign is a technique of product design in which the usual goals of the
project such as performance reliability and cost of manufacturing appear together with
environmental objectives such as reduction of environmental hazards reducing the use of
natural resources increase of energy efficiency and recycling It allows linking the functions
of the product with sustainability aspects reducing environmental impacts and increasing the
presence of eco-efficient products (KARLSSON and LUTTROPP 2006 MANZINI and
VEZZOLI 2005) After Vercarlsteren (2001) many companies consider the ecodesign in
preserving not only the environment but also competitiveness and public image related to the
business and market environmental requirements
Different requirements for ecodesign are proposed in literature Many regard materials
components processes and products characteristics use of energy storage and distribution
packaging and waste (WOLFGANG et al 2005 LUTTROPP and LAGERSTED 2006
FIKSEL 1996) We mean prioritizing resources and actions in practices of ecodesign
Supported by Hermann et al (2007) which speak on measurement of performance on
environmental aspects we find relevant identifying priorities or degree of importance of each

ecodesign construct for companies in a particular industry and the extent to which each
company meets every requirement on each construct We also find relevant understanding
how and why emerges in a company the need for involvement of people from product or
process design in dealing with environmental issues Such kind of involvement may be related
with the mission of the company or with pressures originated by customers and legal agents
So the research main objective was to understand and prioritize relevant aspects in ecodesign
practices in a specific industry the automotive industry Specific objective were (i) to
classify the various aspects concerning ecodesign in objective classes of factors named
constructs (ii) to highlight some of the key factors influencing the adoption and
implementation of ecodesign practices at manufacturing companies and (iii) to find
numerical priorities for the constructs The research question was how can be understood and
how to prioritize the various aspects embedded in ecodesign practices in manufacture
companies of the automotive industry The main research method was the case study First
we gathered information from literature and in focus group sessions with experts organized it
in a tree-like structure that appraise and organize aspects of ecodesign in constructs Second
we chose a mid-sized automotive electronics supplier for electronic parts By interviewing
managers we investigated how and why ecodesign is being incorporated into the design of its
manufactured products Finally we used this structure in a chemical components supplier for
automotive industry for prioritize constructs in two products and respective processes
The numerical assessment was made by companyrsquos managers mediated by researcher in
focus group sessions supported by the Analytic Hierarchy Process (AHP) The AHP method
is cited among others by Chen and Tong (2008) and by Berander (2007) as the method of
decision support most applied to problems of priority in development of products The
theoretical foundation of the AHP is found among others in Forman and Selly (2001) and
Saaty (1980) In this research the criterion for the acceptance of an assessment was adopted
from Saaty (1980) a consistency ratio of less than 010 (CR lt010) Consistency ratio is the
probability that the numerical structure representing managers preference about an issue came
from a random not rational process In the other hand if CR is sufficiently low we can
accept that the decision was taken in rational basis not random
The main contribution of this article is to provide a method for prioritize ecodesign actions in
a specific company The method was developed assuming that the application in other
industries is feasible The remaining of this article begins with some background on
ecodesign encompassing the benefits it offers and the barriers to its implementation research
methodology and findings discussion and contribution and conclusions and suggestions for
continuity Limitations of the research are those related with the method a single industry
and exclusive use of judgement not physical measurement of field variates in prioritization
3 Theoretical background ecodesign
The concept of ecodesign green design or life cycle design refers to the design of new
products and services by applying environmental concerns aiming at prevention of waste
emissions and other forms of environmental impacts along the entire life-cycle of the product
In ecodesign environmental considerations are integrated into product and process design
procedures (WEENEN 1995) Ecodesign has been defined as a concept that integrates
multifaceted aspects of design and environmental considerations into product development in
order to create sustainable solutions that satisfy human needs and desires Ecodesign formally
introduces environmental concerns in the new products development process of a company

(KARLSSON and LUTTROPP 2006) Ecodesign can also be defined as a proactive approach
of environmental management that aims to reduce the total environmental impact of products
and services along their entire life-cycle (PIGOSSO et al 2010)
The factors that motivate adoption of ecodesign are not limited to environmental benefits but
can include saving costs gaining competitive advantage and improving corporate image
(VERCALSTEREN 2001) Some components systems or sub-systems can easily be
recycled reused or remanufactured which is an effective way to reduce both environmental
impacts and costs of the manufacturing processes (PIGOSSO et al 2010) Kazazian (2005)
tells us about eco-conception an approach that considers in conception stage environment
concern as important as factors such as technical feasibility cost control and market demand
Boks (2006) stresses the importance of product designers emphasizing their unique position
and ability to influence environmental strategies Designers can have a key impact when they
enlarge the focus of their efforts giving the environment a prominent position in defining the
parameters of product development However ecodesign tools can present difficulties for
companies Using then can require a high degree of expertise To make ecodesign tools more
useful and accessible we need to help designers link them to more conventional product
development tools (LE POCHAT et al 2007 RAO 2004 LOFTHOUSE 2006)
Despite the amount of tools available ecodesign is not always readily adopted by
manufacturing companies Authors note that industry designers often find the tools difficult to
use (LOFTHOUSE 2006 LE POCHAT et al 2007 LUTTROPP and LAGERSTEDT 2006
BYGGETH and HOCHSCHORNER 2006 BYGGETH et al 2007) According to Lofthouse
(2006) tools often fail to be adopted ldquobecause they do not focus on design but instead are
aimed at strategic management or retrospective analysis of existing productsrdquo The author
notes that what designers actually need is specific information on areas such as materials and
construction techniques The environmental information associated with ecodesign tools is
often very general In most instances the tools do not provide the detailed and specific
information that designers find necessary when working on design projects
Regarding the potential of a company for the application of ecodesign the organization must
assess factors regarding the company (internal) the environment (external) and the product
itself As internal factors we mention (i) motivation of management (ii) position in the
industry which tell us about the companys capacity to influence the specifications of the
product (iii) competitiveness since the leader is more likely to redesign products and (iv) the
industry dynamics which can provide learning and benchmarking for well-succeeded
initiatives Regarding to external factors we mean (i) legal regulation (ii) pressure from
customers and market and (iii) suppliers and partners since in automotive industry they are
essential in manufacturing strategy (VERCALSTEREN 2001) Regarding to the product we
mention that it must be conceived in such a fashion that it can easily be redesigned or at least
disassembled after primary use (BORCHARDT et al 2009b)
Fiksel (1996) proposed a set of practices related to ecodesign (i) to choose low impact raw-
materials preventing from those that can not be recycled or reused (ii) to focus on simplicity
using simpler forms and less quantity of material with replaceable parts and easy repair (iii)
to ensure acceptable amount of hazardous substances (iv) to reduce the use of energy in all
the product life-cycle (v) to use renewable energy (vi) to develop multifunctional products
with sequential functions (after a prior usage the product still is usable in a second way) (vii)
to extend lifetime (viii) to recover packaging or use refilling and (ix) to reduce risks and
works in disassembling tasks Wolfgang et al (2005) proposed for manufactured products

essential requirements that greatly emphasize on eliminating losses in production processes
Luttropp and Lagersted (2006) suggested two operational aspects surface treatment against
dust and corrosion increasing lifetime and easy assembly and disassembly using fixation by
screws or plugs avoiding welding connections
Regarding the factors that can influence implementation of ecodesign practices Boks (2006)
states that the main success factors are related to business aspects such as customization
organization and communication about the project After the author the most serious
obstacles are associated with social and institutional issues such as differences in vision
between managers organizational complexity and lack of internal cooperation Bahmed et al
(2005) state that important success factors are group and management motivation use of
work teams and a standard mechanism for product design providing training and having the
assistance of experts in eco-conception The authors also point out risks factors lack of
specific knowledge lack of understanding regarding the impact of ecodesign on areas such as
regulation cost reduction competitive advantage and organizational image improvement
lack of consensus about how to evaluate products in environmental terms lack of relevant
standards and the belief that environmental goals are necessarily at odds with economic
objectives Boks (2006) notes some factors that can accelerate decision-making on ecodesign
(i) pressure from external sources including legal requirements (ii) economic issues like
partners in the value chain (iii) consumer perceptions and (iv) relevant new technologies
Regulation can play an important role in promoting ecodesign Much of the relevant literature
we reviewed concentrated on regulation in the European Union (EU) which has implemented
some important environmental regulatory directives affecting the automotive and electronics
industries These include the end-of-life vehicles (ELV) directive the waste electrical and
electronic equipment (WEEE) directive and the restriction of hazardous substances (RoHS)
directive In addition the EU has finalized a framework directive for reducing the
environmental impacts of energy-using products through ecodesign (PARK and TAHARA
2008 LE POCHAT et al 2007)
4 Assessing Ecodesign a multicriterial problem
Ecodesign practices is intrinsically a complex abstract object which can be described as a
complex hierarchical system We proposed a method for modeling such complex abstract
objects We have structured hierarchically components in a triple-level structure in order to
describe the object Table 1 shows a number of ecodesign principles and practices that are
applicable in manufacturing in a tree-like structure format suitable for further modeling

The top term the theoretical object is explained by latent constructs based on concepts
explained by indicators performing a tree-like structure in a hierarchical fashion of levels
The structure was built in previous research (BORCHARDT et al 2009b) and was built in
group sessions with scholars and praticants in environmental management and product
development mediated by researchers The leading edge was the works of Fiksel (1996)
Venzke (2002) Luttropp and Lagersted (2006) and Wolfgang et al (2005) The list is not
exhaustive nor definitive since ecodesign is a dynamic field that is constantly evolving as
knowledge and technology develop and circumstances change
As the list suggests the scope of ecodesign is broad and multicriterial embracing product
design impact of raw-material extraction energy consumption industrial waste generation
and disposal and the full range of environmental impacts created throughout the entire life
cycle of products Such multicriteriality suggests using methods like AHP
The AHP (analytic hierarchic process) is well suited to prioritize constructs of a complex
object like ecodesign practices Wind and Saaty (1980) proposed that the AHP represents an
efficient method of dealing with complexity identifying and prioritizing the major
components in which we can structure a complex problem The AHP describes a complex
problem in a hierarchy in which each element of a level is further deconstructed into
subelements and so on until at the lowest representative level Once the hierarchy is defined
its elements are pair-wised compared by the scale [equal importance = 1 a little bit more
important = 3 more important = 5 much more important =7 dominant = 9] Intermediate
values can be used in intermediate graduations Pair-wise comparison produces a preference
matrix A in which aij is the relative importance of the i-th factor with respect to the j-th
factor For n factors we need n(n-1)2 judgments all above the diagonal Below we assigned
the reciprocals values like in (1) (SAATY 1980)

We calculate priorities by finding autovectors with maximum autovalues of matrix A Let A
be the comparison matrix (1) We must find the priorities vector w that satisfies (2)
Components of w are the priorities of the factors (SAATY 1980)
Aw = maxw (2)
By (3) we calculate CR the consistency ratio the probability that the matrix had been
originated by random not rational judgement RI is the average random index obtained by
computer simulation experimentation and given in Table 2
CR = [max ndash n][ RI(n-1)] (3)

If CR lt 10 the judgments can be considered satisfactory otherwise should be reviewed and
improved For instance if someone judges a1 one and a half times more important than a2 and
a2 two times more important than a3 than he or she must consider a1 three times more
important than a3 If the judgment differs there is some inconsistency appraised by CR
(SAATY 1980) Anyway Hogart (1988) advise that we must count on some inconsistency in
mental models of deciders which must be reflected by the CR
5 Research
The research question was how can be understood and how to prioritize the various aspects
embedded in ecodesign practices in manufacture companies of the automotive industry The
answer must improve refute or correct the test hypotheses the presented method The main
objective of research was to test a method for prioritizing constructs in ecodesign practices in
an industry for the sake of reformulate strategic plans reinforcing practices judged more
important and eventually removing resources from those of less importance Secondary
objectives were (i) understand the emergence and practical implications of ecodesign
constructs in the industry and (ii) to distribute the relative weights (100 percentage points)
among the constructs A third objective is left for continuity (iii) to assess categorically the
actual situation of the constructs compare with priority and propose plans for those who have
biggest gaps between priority and performance The main contribution of the research is the
specific description of the case that added to others in growing depth and diversity may
expose regularities about the method and refine it
For questions containing the word how Yin (2009) indicates the case study method Case
studies can contribute exposing regularities that might be useful in formulating a theory about
the object (ECKSTEIN 1975) Repeated cases with similarities can contribute to the building
of a grounded theory (EISENHARDT 1989) Case studies in operations management are
acknowledged as a valid method for exploratory research like this (VOSS et al 2002) The
method aligns with the design research logic as stated by Hevner et al (2004) and Manson
(2006) According to this logic a method like we proposed can be thought of as a result of a
design process like producing a software package or a physical or logical artifact After a
mental or theoretical phase arises an idea that must be checked for viability and refined for
reliability in field cases (MARCH and SMITH 2005) like those here presented The authors
stress in the design research logic there are two important moments in the research the
mental or logical construction of the artifact and its refinement by field cases
51 Previous case understanding ecodesign in the automotive industry
The case took place in a mid-sized manufacturer with consolidated tradition in environmental
management and certified by both ISO 90012000 and ISO 140012004 normalization The
company produces on-board electronic components for vehicles The main research technique
was direct observation as well as interviewing the body of managers They began telling about
ecodesign in the industry as a hole and then about particularities of the company

The automotive industry operates in a highly competitive market with worldwide sale and
distribution The tolerance for product flaws is low especially in the case of vehicle safety
These factors can operate as constraints on the adoption of ecodesign practices by companies
in the industry Regarding natural resources the environmental balance for vehicles is
negative Production requires in raw material about ten times the weight of the car and uses
large amounts of water About forty thousand liters of water are required to manufacture a car
Vehicles consume fuel and lubricating oils most often from non-renewable fossil-based
resources sometimes returning as contaminants In addition cars use tires barely recycled
Moreover vehicles emit significant quantities of air pollutants including carbon dioxide (a
major greenhouse gas) and sulfur dioxide (which contributes to acid rain) Vehicles can also
be difficult to recycle at the end of their useful life They typically contain a variety of
different materials (including plastics and metals as well as electrical and electronic
components) that may be costly and challenging to separate
These impacts reinforce the perception that vehicles are not designed with an emphasis on
preserving the environment and promoting sustainability Partly in response to these concerns
the industry has developed high-performance and hybrid engines running on renewable bio-
fuels and using high-durability synthetic lubricating oils as well as has began using more
parts manufactured with recycled composite materials The industry is also seeking to restrict
the use of hazardous substances and to increase the quantity of returnable packaging and
materials These issues are particularly relevant in the European Union The EUrsquos RoHS
directive had banned the use of certain hazardous materials as constituents in specified parts
Regarding the company as its products involve special safety and security features it is not
allowed to reuse parts that could compromise reliability However raw materials such as
plastics and metals can be recycled The company has developed a complex business-to-
business relationship with its customers The company must meet applicable regulatory
requirements and also depends on customersrsquo approval in order to make changes to its
products When automotive assemblers qualify suppliers they primarily evaluate
characteristics such as reliability of deliver and products performance Suppliers also must
meet all relevant environmental requirements such as those related to restrictions on the use
of hazardous substances However exceeding minimal requirements does not constitute a
preferential or does not construct a competitive advantage factor for a given supplier So the
company has little autonomy in decisions involving introducing ecodesign practices in the
products and has little external compensation in doing so Prices politics are not influenced by
ecodesign practices in the automotive market at least until now
In spite of this the company addressed key issues regarding the environmental management
policy including energy and materials consumption and waste handling and treatment The
main drivers for ecodesign adoption was cost reduction due to dematerializing directives
(using the smallest possible amount of raw material) and to lowering expenditures related to
the treatment of waste The company formed a multidisciplinary group to handle the study
planning and strategic deployment of ecodesign techniques Top management organized a
working group that included people with expertise in relevant areas such as development
trade quality logistics and industrialization The group focused on activities related to the
development of products and processes implementing guidelines that included checklists for
design activities and product life-cycle assessment A huge difficulty was the shortage of
technical information available on environmental impacts of materials Using of standardized
databases is an alternative that the company now studies

Although the results are not yet those planned the body of managers recognized some
positive achievements costs reductions from dematerialization less manufactured products
due to multifunctionality implicating in less items in stock less test sets in the assembly line
less variety in the sales portfolio and higher lots of raw-materials purchased from a lower
number of suppliers reduction in costs due to waste disposal and transportation of raw-
materials
52 Next case prioritizing ecodesign in a company
The next case was developed in a chemical stuff manufactures that supply adhesives paints
greases and various liquid products to the automotive industry The company has several
families of products manufactured in multiple assembly lines and sites Design activities are
organized in teams with different requirements and practices Scarcely a technical
development or advance in one family of product can be extended to others but managerial
advances can be exchanged between groups Anyway due to the sharp differences between
design practices we chose two lines A and B to study Others can be addressed in the
continuity of the research
In focus groups sessions five experts in design for each family of product mediated by
researcher distributing relative weights among the constructs of ecodesign The prioritization
was made with the aid of the AHP In the first rounds calculated CR were nor proper so
researcher oriented experts to review flaws judgements until preference matrixes based on
more rational choices were achieved Experts produced the judgement matrixes of Tables 3
and 4 For the sake of clarity although the judgement did not employ this format we show
the preference matrixes with reorganized rows in decreasing order of importance As a clue
for checking out rationality in the preferences departing from the diagonal to the right side of
the matrix along the line one must find only increasing or at least equal numbers in
sequence If we find a decreasing number that means a flaw or incoherence in judgement

For the product A the most important construct in ecodesign is materials In fact due to its
chemical nature extraction warehousing and transportation of large quantities of A can
greatly affect quarries and its proximity and neighborhood of the manufacturer sites Using
alternate materials should be addressed in further redesign actions although experts stressed

they have little flexibility to change or use new materials due to consolidated technology and
assembly lines facilities For almost the same reasons the second construct in importance is
waste Due to the fact that half-life of the product is short and customers use little amount at a
time is not unusual that large amounts of the product must be discarded by end of usable life
This particularity turns wasting a problematic construct that must be focused in further actions
of redesign The third and fourth constructs are distribution and packaging with similar
priorities We stress that the distribution function includes not only the logistic operations of
transportation inspection and warehousing but also financial operations like assurance of
loads and people safety Packaging has still a significant importance due to the vast amount of
cardboard and wrapping plastic required most of them by no means easy for recycling or
reusing Components characteristics and energy usage have little priorities (lower than 10)
due to the particularities of the product and the manufacture process It requires no special
sub-systems to be assembled in the process is quite simple in little customized quantities and
exothermic what means that a part of the energy spent in it can be recovered and used
elsewhere in the site
Regarding to the judgement it was necessary more than one round but at the end experts
achieved a preference matrix with a very low inconsistency less than 1 meaning a
doubtless rational choice

For the product B as well as in A the most important construct in ecodesign is materials The
production is in bulk big lots but it is customized what means that the material leaves the
site with an assigned destination Exactly as with A due to chemical nature of the product
dependent of natural resources extraction warehousing and transportation can greatly affect
quarries and proximity of such installations and neighborhood of the manufacturer sites In
the same way using alternate materials should be addressed in further redesign actions Due
to similarities between the two products it can be worthwhile addressing unified actions
linking both products mainly regarding logistic operations Different from A the second
construct in importance for B is characteristics of product and process Process is quite
complicated and requires electronic equipment and feedback control in closed-loop fashion
which means maintenance efforts materials consumption and specialized people The process
is endothermic demanding a large amount of energy what explains the third construct in

importance usage of energy Distribution and packaging have similar particularities but
distribution is a little bit more demanding due to warehousing and inspections activities
required by the nature of the logistic operation Different from A waste has little importance
due mainly to the fact that almost always the total amount of the product is consumed in
automotive assemblers Half-life of the product is very long and just-in-time practices
required by assemblers do not allow over-production what assures little problems regarding
final disposals of wastings Regarding to residues well-succeeded experiments conducted in
thermal sites assure an environmental friendly destination contributing to energy generation
for further processes As well as in A no special sub-systems are required to be assembled in
so components are by no means a problem for designers
As in the product A the judgement required more than one round but at the end experts
achieved a preference matrix with a very low inconsistency less than 2 as well as the first
case meaning a doubtless rational choice
Figure 1 presents a graphical comparison between the two products We remark that materials
are the most priority construct in both products Although the teams were formed to work
separately in this case due to the importance of the construct and the similarities of the flaws
unified actions could be planned in order to reduce environmental pressures due to the
handling of materials mainly raw-materials

6 Final remarks
The main purpose of this article was to present a method for prioritizing constructs that
explains ecodesign practices in automotive industry Secondarily the article aimed at
understanding central aspects of ecodesign implementation and practical implications of
ecodesign in the industry and to distribute the relative weights (100 percentage points) among
the constructs in order to reach a prioritization structure A third objective was left for
continuity to assess the situation of the constructs and propose plans for those who have

biggest gaps between priority and performance The research method was the case study First
objective was achieved in a mid-sized supplier of electronic parts The second was achieved
in a chemical manufactures by analyzing two different families of products Due to the
method the main contribution of the research was the specific description of the cases and a
practical application of the prioritization method We stress that with the achievement of the
third objective a company should address the constructs with bigger gaps (the difference
between prioritization and performance) rather than those of higher prioritization
The method combined qualitative research techniques such as focus groups sessions with the
mathematical calculations used to find the vectors of priorities from the preference matrix It
was a limitation of the article the use of assessment based in expertsrsquo judgments opposite to
measurements based in physic conditions from field variates and mathematic models When
physic measurements are used further statistic considerations are necessary once usually the
measured variates are random In the other hand objectives measurement like those provided
by physical variates hold less subjectivity then categorical judgements
As continuity we propose the use of other multicriterial method beyond AHP It is also
suggested to test the method in another industry We also suggest assessment of performance
of the product in the constructs by means of a set of indicators that can explain the construct
So the reformulated actions would focus not necessarily in the most prioritized constructs
but in the constructs with larger gaps between priority and performance The method can also
be applied in the entire or at least a bigger part of the automotive chain The application
along the chain can identify the fragile parts on the ecodesign development and helps to focus
efforts in the chain At last it is proposed to integrate the method to the cleaner production
technologies and reversal logistic models available in literature It is understood that the
method might indicate the ecodesign gaps of a product operation and offer enough support to
the implementation and maintenance of cleaner production and reversal logistics programs in
manufacture in an on-going improvement basis

ecodesign construct for companies in a particular industry and the extent to which each
company meets every requirement on each construct We also find relevant understanding
how and why emerges in a company the need for involvement of people from product or
process design in dealing with environmental issues Such kind of involvement may be related
with the mission of the company or with pressures originated by customers and legal agents
So the research main objective was to understand and prioritize relevant aspects in ecodesign
practices in a specific industry the automotive industry Specific objective were (i) to
classify the various aspects concerning ecodesign in objective classes of factors named
constructs (ii) to highlight some of the key factors influencing the adoption and
implementation of ecodesign practices at manufacturing companies and (iii) to find
numerical priorities for the constructs The research question was how can be understood and
how to prioritize the various aspects embedded in ecodesign practices in manufacture
companies of the automotive industry The main research method was the case study First
we gathered information from literature and in focus group sessions with experts organized it
in a tree-like structure that appraise and organize aspects of ecodesign in constructs Second
we chose a mid-sized automotive electronics supplier for electronic parts By interviewing
managers we investigated how and why ecodesign is being incorporated into the design of its
manufactured products Finally we used this structure in a chemical components supplier for
automotive industry for prioritize constructs in two products and respective processes
The numerical assessment was made by companyrsquos managers mediated by researcher in
focus group sessions supported by the Analytic Hierarchy Process (AHP) The AHP method
is cited among others by Chen and Tong (2008) and by Berander (2007) as the method of
decision support most applied to problems of priority in development of products The
theoretical foundation of the AHP is found among others in Forman and Selly (2001) and
Saaty (1980) In this research the criterion for the acceptance of an assessment was adopted
from Saaty (1980) a consistency ratio of less than 010 (CR lt010) Consistency ratio is the
probability that the numerical structure representing managers preference about an issue came
from a random not rational process In the other hand if CR is sufficiently low we can
accept that the decision was taken in rational basis not random
The main contribution of this article is to provide a method for prioritize ecodesign actions in
a specific company The method was developed assuming that the application in other
industries is feasible The remaining of this article begins with some background on
ecodesign encompassing the benefits it offers and the barriers to its implementation research
methodology and findings discussion and contribution and conclusions and suggestions for
continuity Limitations of the research are those related with the method a single industry
and exclusive use of judgement not physical measurement of field variates in prioritization
3 Theoretical background ecodesign
The concept of ecodesign green design or life cycle design refers to the design of new
products and services by applying environmental concerns aiming at prevention of waste
emissions and other forms of environmental impacts along the entire life-cycle of the product
In ecodesign environmental considerations are integrated into product and process design
procedures (WEENEN 1995) Ecodesign has been defined as a concept that integrates
multifaceted aspects of design and environmental considerations into product development in
order to create sustainable solutions that satisfy human needs and desires Ecodesign formally
introduces environmental concerns in the new products development process of a company

(KARLSSON and LUTTROPP 2006) Ecodesign can also be defined as a proactive approach
of environmental management that aims to reduce the total environmental impact of products
and services along their entire life-cycle (PIGOSSO et al 2010)
The factors that motivate adoption of ecodesign are not limited to environmental benefits but
can include saving costs gaining competitive advantage and improving corporate image
(VERCALSTEREN 2001) Some components systems or sub-systems can easily be
recycled reused or remanufactured which is an effective way to reduce both environmental
impacts and costs of the manufacturing processes (PIGOSSO et al 2010) Kazazian (2005)
tells us about eco-conception an approach that considers in conception stage environment
concern as important as factors such as technical feasibility cost control and market demand
Boks (2006) stresses the importance of product designers emphasizing their unique position
and ability to influence environmental strategies Designers can have a key impact when they
enlarge the focus of their efforts giving the environment a prominent position in defining the
parameters of product development However ecodesign tools can present difficulties for
companies Using then can require a high degree of expertise To make ecodesign tools more
useful and accessible we need to help designers link them to more conventional product
development tools (LE POCHAT et al 2007 RAO 2004 LOFTHOUSE 2006)
Despite the amount of tools available ecodesign is not always readily adopted by
manufacturing companies Authors note that industry designers often find the tools difficult to
use (LOFTHOUSE 2006 LE POCHAT et al 2007 LUTTROPP and LAGERSTEDT 2006
BYGGETH and HOCHSCHORNER 2006 BYGGETH et al 2007) According to Lofthouse
(2006) tools often fail to be adopted ldquobecause they do not focus on design but instead are
aimed at strategic management or retrospective analysis of existing productsrdquo The author
notes that what designers actually need is specific information on areas such as materials and
construction techniques The environmental information associated with ecodesign tools is
often very general In most instances the tools do not provide the detailed and specific
information that designers find necessary when working on design projects
Regarding the potential of a company for the application of ecodesign the organization must
assess factors regarding the company (internal) the environment (external) and the product
itself As internal factors we mention (i) motivation of management (ii) position in the
industry which tell us about the companys capacity to influence the specifications of the
product (iii) competitiveness since the leader is more likely to redesign products and (iv) the
industry dynamics which can provide learning and benchmarking for well-succeeded
initiatives Regarding to external factors we mean (i) legal regulation (ii) pressure from
customers and market and (iii) suppliers and partners since in automotive industry they are
essential in manufacturing strategy (VERCALSTEREN 2001) Regarding to the product we
mention that it must be conceived in such a fashion that it can easily be redesigned or at least
disassembled after primary use (BORCHARDT et al 2009b)
Fiksel (1996) proposed a set of practices related to ecodesign (i) to choose low impact raw-
materials preventing from those that can not be recycled or reused (ii) to focus on simplicity
using simpler forms and less quantity of material with replaceable parts and easy repair (iii)
to ensure acceptable amount of hazardous substances (iv) to reduce the use of energy in all
the product life-cycle (v) to use renewable energy (vi) to develop multifunctional products
with sequential functions (after a prior usage the product still is usable in a second way) (vii)
to extend lifetime (viii) to recover packaging or use refilling and (ix) to reduce risks and
works in disassembling tasks Wolfgang et al (2005) proposed for manufactured products

essential requirements that greatly emphasize on eliminating losses in production processes
Luttropp and Lagersted (2006) suggested two operational aspects surface treatment against
dust and corrosion increasing lifetime and easy assembly and disassembly using fixation by
screws or plugs avoiding welding connections
Regarding the factors that can influence implementation of ecodesign practices Boks (2006)
states that the main success factors are related to business aspects such as customization
organization and communication about the project After the author the most serious
obstacles are associated with social and institutional issues such as differences in vision
between managers organizational complexity and lack of internal cooperation Bahmed et al
(2005) state that important success factors are group and management motivation use of
work teams and a standard mechanism for product design providing training and having the
assistance of experts in eco-conception The authors also point out risks factors lack of
specific knowledge lack of understanding regarding the impact of ecodesign on areas such as
regulation cost reduction competitive advantage and organizational image improvement
lack of consensus about how to evaluate products in environmental terms lack of relevant
standards and the belief that environmental goals are necessarily at odds with economic
objectives Boks (2006) notes some factors that can accelerate decision-making on ecodesign
(i) pressure from external sources including legal requirements (ii) economic issues like
partners in the value chain (iii) consumer perceptions and (iv) relevant new technologies
Regulation can play an important role in promoting ecodesign Much of the relevant literature
we reviewed concentrated on regulation in the European Union (EU) which has implemented
some important environmental regulatory directives affecting the automotive and electronics
industries These include the end-of-life vehicles (ELV) directive the waste electrical and
electronic equipment (WEEE) directive and the restriction of hazardous substances (RoHS)
directive In addition the EU has finalized a framework directive for reducing the
environmental impacts of energy-using products through ecodesign (PARK and TAHARA
2008 LE POCHAT et al 2007)
4 Assessing Ecodesign a multicriterial problem
Ecodesign practices is intrinsically a complex abstract object which can be described as a
complex hierarchical system We proposed a method for modeling such complex abstract
objects We have structured hierarchically components in a triple-level structure in order to
describe the object Table 1 shows a number of ecodesign principles and practices that are
applicable in manufacturing in a tree-like structure format suitable for further modeling

The top term the theoretical object is explained by latent constructs based on concepts
explained by indicators performing a tree-like structure in a hierarchical fashion of levels
The structure was built in previous research (BORCHARDT et al 2009b) and was built in
group sessions with scholars and praticants in environmental management and product
development mediated by researchers The leading edge was the works of Fiksel (1996)
Venzke (2002) Luttropp and Lagersted (2006) and Wolfgang et al (2005) The list is not
exhaustive nor definitive since ecodesign is a dynamic field that is constantly evolving as
knowledge and technology develop and circumstances change
As the list suggests the scope of ecodesign is broad and multicriterial embracing product
design impact of raw-material extraction energy consumption industrial waste generation
and disposal and the full range of environmental impacts created throughout the entire life
cycle of products Such multicriteriality suggests using methods like AHP
The AHP (analytic hierarchic process) is well suited to prioritize constructs of a complex
object like ecodesign practices Wind and Saaty (1980) proposed that the AHP represents an
efficient method of dealing with complexity identifying and prioritizing the major
components in which we can structure a complex problem The AHP describes a complex
problem in a hierarchy in which each element of a level is further deconstructed into
subelements and so on until at the lowest representative level Once the hierarchy is defined
its elements are pair-wised compared by the scale [equal importance = 1 a little bit more
important = 3 more important = 5 much more important =7 dominant = 9] Intermediate
values can be used in intermediate graduations Pair-wise comparison produces a preference
matrix A in which aij is the relative importance of the i-th factor with respect to the j-th
factor For n factors we need n(n-1)2 judgments all above the diagonal Below we assigned
the reciprocals values like in (1) (SAATY 1980)

We calculate priorities by finding autovectors with maximum autovalues of matrix A Let A
be the comparison matrix (1) We must find the priorities vector w that satisfies (2)
Components of w are the priorities of the factors (SAATY 1980)
Aw = maxw (2)
By (3) we calculate CR the consistency ratio the probability that the matrix had been
originated by random not rational judgement RI is the average random index obtained by
computer simulation experimentation and given in Table 2
CR = [max ndash n][ RI(n-1)] (3)

If CR lt 10 the judgments can be considered satisfactory otherwise should be reviewed and
improved For instance if someone judges a1 one and a half times more important than a2 and
a2 two times more important than a3 than he or she must consider a1 three times more
important than a3 If the judgment differs there is some inconsistency appraised by CR
(SAATY 1980) Anyway Hogart (1988) advise that we must count on some inconsistency in
mental models of deciders which must be reflected by the CR
5 Research
The research question was how can be understood and how to prioritize the various aspects
embedded in ecodesign practices in manufacture companies of the automotive industry The
answer must improve refute or correct the test hypotheses the presented method The main
objective of research was to test a method for prioritizing constructs in ecodesign practices in
an industry for the sake of reformulate strategic plans reinforcing practices judged more
important and eventually removing resources from those of less importance Secondary
objectives were (i) understand the emergence and practical implications of ecodesign
constructs in the industry and (ii) to distribute the relative weights (100 percentage points)
among the constructs A third objective is left for continuity (iii) to assess categorically the
actual situation of the constructs compare with priority and propose plans for those who have
biggest gaps between priority and performance The main contribution of the research is the
specific description of the case that added to others in growing depth and diversity may
expose regularities about the method and refine it
For questions containing the word how Yin (2009) indicates the case study method Case
studies can contribute exposing regularities that might be useful in formulating a theory about
the object (ECKSTEIN 1975) Repeated cases with similarities can contribute to the building
of a grounded theory (EISENHARDT 1989) Case studies in operations management are
acknowledged as a valid method for exploratory research like this (VOSS et al 2002) The
method aligns with the design research logic as stated by Hevner et al (2004) and Manson
(2006) According to this logic a method like we proposed can be thought of as a result of a
design process like producing a software package or a physical or logical artifact After a
mental or theoretical phase arises an idea that must be checked for viability and refined for
reliability in field cases (MARCH and SMITH 2005) like those here presented The authors
stress in the design research logic there are two important moments in the research the
mental or logical construction of the artifact and its refinement by field cases
51 Previous case understanding ecodesign in the automotive industry
The case took place in a mid-sized manufacturer with consolidated tradition in environmental
management and certified by both ISO 90012000 and ISO 140012004 normalization The
company produces on-board electronic components for vehicles The main research technique
was direct observation as well as interviewing the body of managers They began telling about
ecodesign in the industry as a hole and then about particularities of the company

The automotive industry operates in a highly competitive market with worldwide sale and
distribution The tolerance for product flaws is low especially in the case of vehicle safety
These factors can operate as constraints on the adoption of ecodesign practices by companies
in the industry Regarding natural resources the environmental balance for vehicles is
negative Production requires in raw material about ten times the weight of the car and uses
large amounts of water About forty thousand liters of water are required to manufacture a car
Vehicles consume fuel and lubricating oils most often from non-renewable fossil-based
resources sometimes returning as contaminants In addition cars use tires barely recycled
Moreover vehicles emit significant quantities of air pollutants including carbon dioxide (a
major greenhouse gas) and sulfur dioxide (which contributes to acid rain) Vehicles can also
be difficult to recycle at the end of their useful life They typically contain a variety of
different materials (including plastics and metals as well as electrical and electronic
components) that may be costly and challenging to separate
These impacts reinforce the perception that vehicles are not designed with an emphasis on
preserving the environment and promoting sustainability Partly in response to these concerns
the industry has developed high-performance and hybrid engines running on renewable bio-
fuels and using high-durability synthetic lubricating oils as well as has began using more
parts manufactured with recycled composite materials The industry is also seeking to restrict
the use of hazardous substances and to increase the quantity of returnable packaging and
materials These issues are particularly relevant in the European Union The EUrsquos RoHS
directive had banned the use of certain hazardous materials as constituents in specified parts
Regarding the company as its products involve special safety and security features it is not
allowed to reuse parts that could compromise reliability However raw materials such as
plastics and metals can be recycled The company has developed a complex business-to-
business relationship with its customers The company must meet applicable regulatory
requirements and also depends on customersrsquo approval in order to make changes to its
products When automotive assemblers qualify suppliers they primarily evaluate
characteristics such as reliability of deliver and products performance Suppliers also must
meet all relevant environmental requirements such as those related to restrictions on the use
of hazardous substances However exceeding minimal requirements does not constitute a
preferential or does not construct a competitive advantage factor for a given supplier So the
company has little autonomy in decisions involving introducing ecodesign practices in the
products and has little external compensation in doing so Prices politics are not influenced by
ecodesign practices in the automotive market at least until now
In spite of this the company addressed key issues regarding the environmental management
policy including energy and materials consumption and waste handling and treatment The
main drivers for ecodesign adoption was cost reduction due to dematerializing directives
(using the smallest possible amount of raw material) and to lowering expenditures related to
the treatment of waste The company formed a multidisciplinary group to handle the study
planning and strategic deployment of ecodesign techniques Top management organized a
working group that included people with expertise in relevant areas such as development
trade quality logistics and industrialization The group focused on activities related to the
development of products and processes implementing guidelines that included checklists for
design activities and product life-cycle assessment A huge difficulty was the shortage of
technical information available on environmental impacts of materials Using of standardized
databases is an alternative that the company now studies

Although the results are not yet those planned the body of managers recognized some
positive achievements costs reductions from dematerialization less manufactured products
due to multifunctionality implicating in less items in stock less test sets in the assembly line
less variety in the sales portfolio and higher lots of raw-materials purchased from a lower
number of suppliers reduction in costs due to waste disposal and transportation of raw-
materials
52 Next case prioritizing ecodesign in a company
The next case was developed in a chemical stuff manufactures that supply adhesives paints
greases and various liquid products to the automotive industry The company has several
families of products manufactured in multiple assembly lines and sites Design activities are
organized in teams with different requirements and practices Scarcely a technical
development or advance in one family of product can be extended to others but managerial
advances can be exchanged between groups Anyway due to the sharp differences between
design practices we chose two lines A and B to study Others can be addressed in the
continuity of the research
In focus groups sessions five experts in design for each family of product mediated by
researcher distributing relative weights among the constructs of ecodesign The prioritization
was made with the aid of the AHP In the first rounds calculated CR were nor proper so
researcher oriented experts to review flaws judgements until preference matrixes based on
more rational choices were achieved Experts produced the judgement matrixes of Tables 3
and 4 For the sake of clarity although the judgement did not employ this format we show
the preference matrixes with reorganized rows in decreasing order of importance As a clue
for checking out rationality in the preferences departing from the diagonal to the right side of
the matrix along the line one must find only increasing or at least equal numbers in
sequence If we find a decreasing number that means a flaw or incoherence in judgement

For the product A the most important construct in ecodesign is materials In fact due to its
chemical nature extraction warehousing and transportation of large quantities of A can
greatly affect quarries and its proximity and neighborhood of the manufacturer sites Using
alternate materials should be addressed in further redesign actions although experts stressed

11
they have little flexibility to change or use new materials due to consolidated technology and
assembly lines facilities For almost the same reasons the second construct in importance is
waste Due to the fact that half-life of the product is short and customers use little amount at a
time is not unusual that large amounts of the product must be discarded by end of usable life
This particularity turns wasting a problematic construct that must be focused in further actions
of redesign The third and fourth constructs are distribution and packaging with similar
priorities We stress that the distribution function includes not only the logistic operations of
transportation inspection and warehousing but also financial operations like assurance of
loads and people safety Packaging has still a significant importance due to the vast amount of
cardboard and wrapping plastic required most of them by no means easy for recycling or
reusing Components characteristics and energy usage have little priorities (lower than 10)
due to the particularities of the product and the manufacture process It requires no special
sub-systems to be assembled in the process is quite simple in little customized quantities and
exothermic what means that a part of the energy spent in it can be recovered and used
elsewhere in the site
Regarding to the judgement it was necessary more than one round but at the end experts
achieved a preference matrix with a very low inconsistency less than 1 meaning a
doubtless rational choice

For the product B as well as in A the most important construct in ecodesign is materials The
production is in bulk big lots but it is customized what means that the material leaves the
site with an assigned destination Exactly as with A due to chemical nature of the product
dependent of natural resources extraction warehousing and transportation can greatly affect
quarries and proximity of such installations and neighborhood of the manufacturer sites In
the same way using alternate materials should be addressed in further redesign actions Due
to similarities between the two products it can be worthwhile addressing unified actions
linking both products mainly regarding logistic operations Different from A the second
construct in importance for B is characteristics of product and process Process is quite
complicated and requires electronic equipment and feedback control in closed-loop fashion
which means maintenance efforts materials consumption and specialized people The process
is endothermic demanding a large amount of energy what explains the third construct in

importance usage of energy Distribution and packaging have similar particularities but
distribution is a little bit more demanding due to warehousing and inspections activities
required by the nature of the logistic operation Different from A waste has little importance
due mainly to the fact that almost always the total amount of the product is consumed in
automotive assemblers Half-life of the product is very long and just-in-time practices
required by assemblers do not allow over-production what assures little problems regarding
final disposals of wastings Regarding to residues well-succeeded experiments conducted in
thermal sites assure an environmental friendly destination contributing to energy generation
for further processes As well as in A no special sub-systems are required to be assembled in
so components are by no means a problem for designers
As in the product A the judgement required more than one round but at the end experts
achieved a preference matrix with a very low inconsistency less than 2 as well as the first
case meaning a doubtless rational choice
Figure 1 presents a graphical comparison between the two products We remark that materials
are the most priority construct in both products Although the teams were formed to work
separately in this case due to the importance of the construct and the similarities of the flaws
unified actions could be planned in order to reduce environmental pressures due to the
handling of materials mainly raw-materials

6 Final remarks
The main purpose of this article was to present a method for prioritizing constructs that
explains ecodesign practices in automotive industry Secondarily the article aimed at
understanding central aspects of ecodesign implementation and practical implications of
ecodesign in the industry and to distribute the relative weights (100 percentage points) among
the constructs in order to reach a prioritization structure A third objective was left for
continuity to assess the situation of the constructs and propose plans for those who have

biggest gaps between priority and performance The research method was the case study First
objective was achieved in a mid-sized supplier of electronic parts The second was achieved
in a chemical manufactures by analyzing two different families of products Due to the
method the main contribution of the research was the specific description of the cases and a
practical application of the prioritization method We stress that with the achievement of the
third objective a company should address the constructs with bigger gaps (the difference
between prioritization and performance) rather than those of higher prioritization
The method combined qualitative research techniques such as focus groups sessions with the
mathematical calculations used to find the vectors of priorities from the preference matrix It
was a limitation of the article the use of assessment based in expertsrsquo judgments opposite to
measurements based in physic conditions from field variates and mathematic models When
physic measurements are used further statistic considerations are necessary once usually the
measured variates are random In the other hand objectives measurement like those provided
by physical variates hold less subjectivity then categorical judgements
As continuity we propose the use of other multicriterial method beyond AHP It is also
suggested to test the method in another industry We also suggest assessment of performance
of the product in the constructs by means of a set of indicators that can explain the construct
So the reformulated actions would focus not necessarily in the most prioritized constructs
but in the constructs with larger gaps between priority and performance The method can also
be applied in the entire or at least a bigger part of the automotive chain The application
along the chain can identify the fragile parts on the ecodesign development and helps to focus
efforts in the chain At last it is proposed to integrate the method to the cleaner production
technologies and reversal logistic models available in literature It is understood that the
method might indicate the ecodesign gaps of a product operation and offer enough support to
the implementation and maintenance of cleaner production and reversal logistics programs in
manufacture in an on-going improvement basis

(KARLSSON and LUTTROPP 2006) Ecodesign can also be defined as a proactive approach
of environmental management that aims to reduce the total environmental impact of products
and services along their entire life-cycle (PIGOSSO et al 2010)
The factors that motivate adoption of ecodesign are not limited to environmental benefits but
can include saving costs gaining competitive advantage and improving corporate image
(VERCALSTEREN 2001) Some components systems or sub-systems can easily be
recycled reused or remanufactured which is an effective way to reduce both environmental
impacts and costs of the manufacturing processes (PIGOSSO et al 2010) Kazazian (2005)
tells us about eco-conception an approach that considers in conception stage environment
concern as important as factors such as technical feasibility cost control and market demand
Boks (2006) stresses the importance of product designers emphasizing their unique position
and ability to influence environmental strategies Designers can have a key impact when they
enlarge the focus of their efforts giving the environment a prominent position in defining the
parameters of product development However ecodesign tools can present difficulties for
companies Using then can require a high degree of expertise To make ecodesign tools more
useful and accessible we need to help designers link them to more conventional product
development tools (LE POCHAT et al 2007 RAO 2004 LOFTHOUSE 2006)
Despite the amount of tools available ecodesign is not always readily adopted by
manufacturing companies Authors note that industry designers often find the tools difficult to
use (LOFTHOUSE 2006 LE POCHAT et al 2007 LUTTROPP and LAGERSTEDT 2006
BYGGETH and HOCHSCHORNER 2006 BYGGETH et al 2007) According to Lofthouse
(2006) tools often fail to be adopted ldquobecause they do not focus on design but instead are
aimed at strategic management or retrospective analysis of existing productsrdquo The author
notes that what designers actually need is specific information on areas such as materials and
construction techniques The environmental information associated with ecodesign tools is
often very general In most instances the tools do not provide the detailed and specific
information that designers find necessary when working on design projects
Regarding the potential of a company for the application of ecodesign the organization must
assess factors regarding the company (internal) the environment (external) and the product
itself As internal factors we mention (i) motivation of management (ii) position in the
industry which tell us about the companys capacity to influence the specifications of the
product (iii) competitiveness since the leader is more likely to redesign products and (iv) the
industry dynamics which can provide learning and benchmarking for well-succeeded
initiatives Regarding to external factors we mean (i) legal regulation (ii) pressure from
customers and market and (iii) suppliers and partners since in automotive industry they are
essential in manufacturing strategy (VERCALSTEREN 2001) Regarding to the product we
mention that it must be conceived in such a fashion that it can easily be redesigned or at least
disassembled after primary use (BORCHARDT et al 2009b)
Fiksel (1996) proposed a set of practices related to ecodesign (i) to choose low impact raw-
materials preventing from those that can not be recycled or reused (ii) to focus on simplicity
using simpler forms and less quantity of material with replaceable parts and easy repair (iii)
to ensure acceptable amount of hazardous substances (iv) to reduce the use of energy in all
the product life-cycle (v) to use renewable energy (vi) to develop multifunctional products
with sequential functions (after a prior usage the product still is usable in a second way) (vii)
to extend lifetime (viii) to recover packaging or use refilling and (ix) to reduce risks and
works in disassembling tasks Wolfgang et al (2005) proposed for manufactured products

essential requirements that greatly emphasize on eliminating losses in production processes
Luttropp and Lagersted (2006) suggested two operational aspects surface treatment against
dust and corrosion increasing lifetime and easy assembly and disassembly using fixation by
screws or plugs avoiding welding connections
Regarding the factors that can influence implementation of ecodesign practices Boks (2006)
states that the main success factors are related to business aspects such as customization
organization and communication about the project After the author the most serious
obstacles are associated with social and institutional issues such as differences in vision
between managers organizational complexity and lack of internal cooperation Bahmed et al
(2005) state that important success factors are group and management motivation use of
work teams and a standard mechanism for product design providing training and having the
assistance of experts in eco-conception The authors also point out risks factors lack of
specific knowledge lack of understanding regarding the impact of ecodesign on areas such as
regulation cost reduction competitive advantage and organizational image improvement
lack of consensus about how to evaluate products in environmental terms lack of relevant
standards and the belief that environmental goals are necessarily at odds with economic
objectives Boks (2006) notes some factors that can accelerate decision-making on ecodesign
(i) pressure from external sources including legal requirements (ii) economic issues like
partners in the value chain (iii) consumer perceptions and (iv) relevant new technologies
Regulation can play an important role in promoting ecodesign Much of the relevant literature
we reviewed concentrated on regulation in the European Union (EU) which has implemented
some important environmental regulatory directives affecting the automotive and electronics
industries These include the end-of-life vehicles (ELV) directive the waste electrical and
electronic equipment (WEEE) directive and the restriction of hazardous substances (RoHS)
directive In addition the EU has finalized a framework directive for reducing the
environmental impacts of energy-using products through ecodesign (PARK and TAHARA
2008 LE POCHAT et al 2007)
4 Assessing Ecodesign a multicriterial problem
Ecodesign practices is intrinsically a complex abstract object which can be described as a
complex hierarchical system We proposed a method for modeling such complex abstract

The top term the theoretical object is explained by latent constructs based on concepts
explained by indicators performing a tree-like structure in a hierarchical fashion of levels
The structure was built in previous research (BORCHARDT et al 2009b) and was built in
group sessions with scholars and praticants in environmental management and product
development mediated by researchers The leading edge was the works of Fiksel (1996)
Venzke (2002) Luttropp and Lagersted (2006) and Wolfgang et al (2005) The list is not
exhaustive nor definitive since ecodesign is a dynamic field that is constantly evolving as
knowledge and technology develop and circumstances change
As the list suggests the scope of ecodesign is broad and multicriterial embracing product
design impact of raw-material extraction energy consumption industrial waste generation
and disposal and the full range of environmental impacts created throughout the entire life
cycle of products Such multicriteriality suggests using methods like AHP
The AHP (analytic hierarchic process) is well suited to prioritize constructs of a complex
object like ecodesign practices Wind and Saaty (1980) proposed that the AHP represents an
efficient method of dealing with complexity identifying and prioritizing the major
components in which we can structure a complex problem The AHP describes a complex
problem in a hierarchy in which each element of a level is further deconstructed into
subelements and so on until at the lowest representative level Once the hierarchy is defined
its elements are pair-wised compared by the scale [equal importance = 1 a little bit more
important = 3 more important = 5 much more important =7 dominant = 9] Intermediate
values can be used in intermediate graduations Pair-wise comparison produces a preference
matrix A in which aij is the relative importance of the i-th factor with respect to the j-th
factor For n factors we need n(n-1)2 judgments all above the diagonal Below we assigned
the reciprocals values like in (1) (SAATY 1980)

We calculate priorities by finding autovectors with maximum autovalues of matrix A Let A
be the comparison matrix (1) We must find the priorities vector w that satisfies (2)
Components of w are the priorities of the factors (SAATY 1980)
Aw = maxw (2)
By (3) we calculate CR the consistency ratio the probability that the matrix had been
originated by random not rational judgement RI is the average random index obtained by
computer simulation experimentation and given in Table 2
CR = [max ndash n][ RI(n-1)] (3)

If CR lt 10 the judgments can be considered satisfactory otherwise should be reviewed and
improved For instance if someone judges a1 one and a half times more important than a2 and
a2 two times more important than a3 than he or she must consider a1 three times more
important than a3 If the judgment differs there is some inconsistency appraised by CR
(SAATY 1980) Anyway Hogart (1988) advise that we must count on some inconsistency in
mental models of deciders which must be reflected by the CR
5 Research
The research question was how can be understood and how to prioritize the various aspects
embedded in ecodesign practices in manufacture companies of the automotive industry The
answer must improve refute or correct the test hypotheses the presented method The main
objective of research was to test a method for prioritizing constructs in ecodesign practices in
an industry for the sake of reformulate strategic plans reinforcing practices judged more
important and eventually removing resources from those of less importance Secondary
objectives were (i) understand the emergence and practical implications of ecodesign
constructs in the industry and (ii) to distribute the relative weights (100 percentage points)
among the constructs A third objective is left for continuity (iii) to assess categorically the
actual situation of the constructs compare with priority and propose plans for those who have
biggest gaps between priority and performance The main contribution of the research is the
specific description of the case that added to others in growing depth and diversity may
expose regularities about the method and refine it
For questions containing the word how Yin (2009) indicates the case study method Case
studies can contribute exposing regularities that might be useful in formulating a theory about
the object (ECKSTEIN 1975) Repeated cases with similarities can contribute to the building
of a grounded theory (EISENHARDT 1989) Case studies in operations management are
acknowledged as a valid method for exploratory research like this (VOSS et al 2002) The
method aligns with the design research logic as stated by Hevner et al (2004) and Manson
(2006) According to this logic a method like we proposed can be thought of as a result of a
design process like producing a software package or a physical or logical artifact After a
mental or theoretical phase arises an idea that must be checked for viability and refined for
reliability in field cases (MARCH and SMITH 2005) like those here presented The authors
stress in the design research logic there are two important moments in the research the
mental or logical construction of the artifact and its refinement by field cases
51 Previous case understanding ecodesign in the automotive industry
The case took place in a mid-sized manufacturer with consolidated tradition in environmental
management and certified by both ISO 90012000 and ISO 140012004 normalization The
company produces on-board electronic components for vehicles The main research technique
was direct observation as well as interviewing the body of managers They began telling about
ecodesign in the industry as a hole and then about particularities of the company

The automotive industry operates in a highly competitive market with worldwide sale and
distribution The tolerance for product flaws is low especially in the case of vehicle safety
These factors can operate as constraints on the adoption of ecodesign practices by companies
in the industry Regarding natural resources the environmental balance for vehicles is
negative Production requires in raw material about ten times the weight of the car and uses
large amounts of water About forty thousand liters of water are required to manufacture a car
Vehicles consume fuel and lubricating oils most often from non-renewable fossil-based
resources sometimes returning as contaminants In addition cars use tires barely recycled
Moreover vehicles emit significant quantities of air pollutants including carbon dioxide (a
major greenhouse gas) and sulfur dioxide (which contributes to acid rain) Vehicles can also
be difficult to recycle at the end of their useful life They typically contain a variety of
different materials (including plastics and metals as well as electrical and electronic
components) that may be costly and challenging to separate
These impacts reinforce the perception that vehicles are not designed with an emphasis on
preserving the environment and promoting sustainability Partly in response to these concerns
the industry has developed high-performance and hybrid engines running on renewable bio-
fuels and using high-durability synthetic lubricating oils as well as has began using more
parts manufactured with recycled composite materials The industry is also seeking to restrict
the use of hazardous substances and to increase the quantity of returnable packaging and
materials These issues are particularly relevant in the European Union The EUrsquos RoHS
directive had banned the use of certain hazardous materials as constituents in specified parts
Regarding the company as its products involve special safety and security features it is not
allowed to reuse parts that could compromise reliability However raw materials such as
plastics and metals can be recycled The company has developed a complex business-to-
business relationship with its customers The company must meet applicable regulatory
requirements and also depends on customersrsquo approval in order to make changes to its
products When automotive assemblers qualify suppliers they primarily evaluate
characteristics such as reliability of deliver and products performance Suppliers also must
meet all relevant environmental requirements such as those related to restrictions on the use
of hazardous substances However exceeding minimal requirements does not constitute a
preferential or does not construct a competitive advantage factor for a given supplier So the
company has little autonomy in decisions involving introducing ecodesign practices in the
products and has little external compensation in doing so Prices politics are not influenced by
ecodesign practices in the automotive market at least until now
In spite of this the company addressed key issues regarding the environmental management
policy including energy and materials consumption and waste handling and treatment The
main drivers for ecodesign adoption was cost reduction due to dematerializing directives
(using the smallest possible amount of raw material) and to lowering expenditures related to
the treatment of waste The company formed a multidisciplinary group to handle the study
planning and strategic deployment of ecodesign techniques Top management organized a
working group that included people with expertise in relevant areas such as development
trade quality logistics and industrialization The group focused on activities related to the
development of products and processes implementing guidelines that included checklists for
design activities and product life-cycle assessment A huge difficulty was the shortage of
technical information available on environmental impacts of materials Using of standardized
databases is an alternative that the company now studies

Although the results are not yet those planned the body of managers recognized some
positive achievements costs reductions from dematerialization less manufactured products
due to multifunctionality implicating in less items in stock less test sets in the assembly line
less variety in the sales portfolio and higher lots of raw-materials purchased from a lower
number of suppliers reduction in costs due to waste disposal and transportation of raw-
materials
52 Next case prioritizing ecodesign in a company
The next case was developed in a chemical stuff manufactures that supply adhesives paints
greases and various liquid products to the automotive industry The company has several
families of products manufactured in multiple assembly lines and sites Design activities are
organized in teams with different requirements and practices Scarcely a technical
development or advance in one family of product can be extended to others but managerial
advances can be exchanged between groups Anyway due to the sharp differences between
design practices we chose two lines A and B to study Others can be addressed in the
continuity of the research
In focus groups sessions five experts in design for each family of product mediated by
researcher distributing relative weights among the constructs of ecodesign The prioritization
was made with the aid of the AHP In the first rounds calculated CR were nor proper so
researcher oriented experts to review flaws judgements until preference matrixes based on
more rational choices were achieved Experts produced the judgement matrixes of Tables 3
and 4 For the sake of clarity although the judgement did not employ this format we show
the preference matrixes with reorganized rows in decreasing order of importance As a clue
for checking out rationality in the preferences departing from the diagonal to the right side of
the matrix along the line one must find only increasing or at least equal numbers in
sequence If we find a decreasing number that means a flaw or incoherence in judgement

For the product A the most important construct in ecodesign is materials In fact due to its
chemical nature extraction warehousing and transportation of large quantities of A can
greatly affect quarries and its proximity and neighborhood of the manufacturer sites Using
alternate materials should be addressed in further redesign actions although experts stressed

they have little flexibility to change or use new materials due to consolidated technology and
assembly lines facilities For almost the same reasons the second construct in importance is
waste Due to the fact that half-life of the product is short and customers use little amount at a
time is not unusual that large amounts of the product must be discarded by end of usable life
This particularity turns wasting a problematic construct that must be focused in further actions
of redesign The third and fourth constructs are distribution and packaging with similar
priorities We stress that the distribution function includes not only the logistic operations of
transportation inspection and warehousing but also financial operations like assurance of
loads and people safety Packaging has still a significant importance due to the vast amount of
cardboard and wrapping plastic required most of them by no means easy for recycling or
reusing Components characteristics and energy usage have little priorities (lower than 10)
due to the particularities of the product and the manufacture process It requires no special
sub-systems to be assembled in the process is quite simple in little customized quantities and
exothermic what means that a part of the energy spent in it can be recovered and used
elsewhere in the site
Regarding to the judgement it was necessary more than one round but at the end experts
achieved a preference matrix with a very low inconsistency less than 1 meaning a
doubtless rational choice

For the product B as well as in A the most important construct in ecodesign is materials The
production is in bulk big lots but it is customized what means that the material leaves the
site with an assigned destination Exactly as with A due to chemical nature of the product
dependent of natural resources extraction warehousing and transportation can greatly affect
quarries and proximity of such installations and neighborhood of the manufacturer sites In
the same way using alternate materials should be addressed in further redesign actions Due
to similarities between the two products it can be worthwhile addressing unified actions
linking both products mainly regarding logistic operations Different from A the second
construct in importance for B is characteristics of product and process Process is quite
complicated and requires electronic equipment and feedback control in closed-loop fashion
which means maintenance efforts materials consumption and specialized people The process
is endothermic demanding a large amount of energy what explains the third construct in

importance usage of energy Distribution and packaging have similar particularities but
distribution is a little bit more demanding due to warehousing and inspections activities
required by the nature of the logistic operation Different from A waste has little importance
due mainly to the fact that almost always the total amount of the product is consumed in
automotive assemblers Half-life of the product is very long and just-in-time practices
required by assemblers do not allow over-production what assures little problems regarding
final disposals of wastings Regarding to residues well-succeeded experiments conducted in
thermal sites assure an environmental friendly destination contributing to energy generation
for further processes As well as in A no special sub-systems are required to be assembled in
so components are by no means a problem for designers
As in the product A the judgement required more than one round but at the end experts
achieved a preference matrix with a very low inconsistency less than 2 as well as the first
case meaning a doubtless rational choice
Figure 1 presents a graphical comparison between the two products We remark that materials
are the most priority construct in both products Although the teams were formed to work
separately in this case due to the importance of the construct and the similarities of the flaws
unified actions could be planned in order to reduce environmental pressures due to the
handling of materials mainly raw-materials

6 Final remarks
The main purpose of this article was to present a method for prioritizing constructs that
explains ecodesign practices in automotive industry Secondarily the article aimed at
understanding central aspects of ecodesign implementation and practical implications of
ecodesign in the industry and to distribute the relative weights (100 percentage points) among
the constructs in order to reach a prioritization structure A third objective was left for
continuity to assess the situation of the constructs and propose plans for those who have

biggest gaps between priority and performance The research method was the case study First
objective was achieved in a mid-sized supplier of electronic parts The second was achieved
in a chemical manufactures by analyzing two different families of products Due to the
method the main contribution of the research was the specific description of the cases and a
practical application of the prioritization method We stress that with the achievement of the
third objective a company should address the constructs with bigger gaps (the difference
between prioritization and performance) rather than those of higher prioritization
The method combined qualitative research techniques such as focus groups sessions with the
mathematical calculations used to find the vectors of priorities from the preference matrix It
was a limitation of the article the use of assessment based in expertsrsquo judgments opposite to
measurements based in physic conditions from field variates and mathematic models When
physic measurements are used further statistic considerations are necessary once usually the
measured variates are random In the other hand objectives measurement like those provided
by physical variates hold less subjectivity then categorical judgements
As continuity we propose the use of other multicriterial method beyond AHP It is also
suggested to test the method in another industry We also suggest assessment of performance
of the product in the constructs by means of a set of indicators that can explain the construct
So the reformulated actions would focus not necessarily in the most prioritized constructs
but in the constructs with larger gaps between priority and performance The method can also
be applied in the entire or at least a bigger part of the automotive chain The application
along the chain can identify the fragile parts on the ecodesign development and helps to focus
efforts in the chain At last it is proposed to integrate the method to the cleaner production
technologies and reversal logistic models available in literature It is understood that the
method might indicate the ecodesign gaps of a product operation and offer enough support to
the implementation and maintenance of cleaner production and reversal logistics programs in
manufacture in an on-going improvement basis

essential requirements that greatly emphasize on eliminating losses in production processes
Luttropp and Lagersted (2006) suggested two operational aspects surface treatment against
dust and corrosion increasing lifetime and easy assembly and disassembly using fixation by
screws or plugs avoiding welding connections
Regarding the factors that can influence implementation of ecodesign practices Boks (2006)
states that the main success factors are related to business aspects such as customization
organization and communication about the project After the author the most serious
obstacles are associated with social and institutional issues such as differences in vision
between managers organizational complexity and lack of internal cooperation Bahmed et al
(2005) state that important success factors are group and management motivation use of
work teams and a standard mechanism for product design providing training and having the
assistance of experts in eco-conception The authors also point out risks factors lack of
specific knowledge lack of understanding regarding the impact of ecodesign on areas such as
regulation cost reduction competitive advantage and organizational image improvement
lack of consensus about how to evaluate products in environmental terms lack of relevant
standards and the belief that environmental goals are necessarily at odds with economic
objectives Boks (2006) notes some factors that can accelerate decision-making on ecodesign
(i) pressure from external sources including legal requirements (ii) economic issues like
partners in the value chain (iii) consumer perceptions and (iv) relevant new technologies
Regulation can play an important role in promoting ecodesign Much of the relevant literature
we reviewed concentrated on regulation in the European Union (EU) which has implemented
some important environmental regulatory directives affecting the automotive and electronics
industries These include the end-of-life vehicles (ELV) directive the waste electrical and
electronic equipment (WEEE) directive and the restriction of hazardous substances (RoHS)
directive In addition the EU has finalized a framework directive for reducing the
environmental impacts of energy-using products through ecodesign (PARK and TAHARA
2008 LE POCHAT et al 2007)
4 Assessing Ecodesign a multicriterial problem
Ecodesign practices is intrinsically a complex abstract object which can be described as a
complex hierarchical system We proposed a method for modeling such complex abstract
objects We have structured hierarchically components in a triple-level structure in order to
describe the object Table 1 shows a number of ecodesign principles and practices that are
applicable in manufacturing in a tree-like structure format suitable for further modeling

The top term the theoretical object is explained by latent constructs based on concepts
explained by indicators performing a tree-like structure in a hierarchical fashion of levels
The structure was built in previous research (BORCHARDT et al 2009b) and was built in
group sessions with scholars and praticants in environmental management and product
development mediated by researchers The leading edge was the works of Fiksel (1996)
Venzke (2002) Luttropp and Lagersted (2006) and Wolfgang et al (2005) The list is not
exhaustive nor definitive since ecodesign is a dynamic field that is constantly evolving as
knowledge and technology develop and circumstances change
As the list suggests the scope of ecodesign is broad and multicriterial embracing product
design impact of raw-material extraction energy consumption industrial waste generation
and disposal and the full range of environmental impacts created throughout the entire life
cycle of products Such multicriteriality suggests using methods like AHP
The AHP (analytic hierarchic process) is well suited to prioritize constructs of a complex
object like ecodesign practices Wind and Saaty (1980) proposed that the AHP represents an
efficient method of dealing with complexity identifying and prioritizing the major
components in which we can structure a complex problem The AHP describes a complex
problem in a hierarchy in which each element of a level is further deconstructed into
subelements and so on until at the lowest representative level Once the hierarchy is defined
its elements are pair-wised compared by the scale [equal importance = 1 a little bit more
important = 3 more important = 5 much more important =7 dominant = 9] Intermediate
values can be used in intermediate graduations Pair-wise comparison produces a preference
matrix A in which aij is the relative importance of the i-th factor with respect to the j-th
factor For n factors we need n(n-1)2 judgments all above the diagonal Below we assigned
the reciprocals values like in (1) (SAATY 1980)

We calculate priorities by finding autovectors with maximum autovalues of matrix A Let A
be the comparison matrix (1) We must find the priorities vector w that satisfies (2)
Components of w are the priorities of the factors (SAATY 1980)
Aw = maxw (2)
By (3) we calculate CR the consistency ratio the probability that the matrix had been
originated by random not rational judgement RI is the average random index obtained by
computer simulation experimentation and given in Table 2
CR = [max ndash n][ RI(n-1)] (3)

If CR lt 10 the judgments can be considered satisfactory otherwise should be reviewed and
improved For instance if someone judges a1 one and a half times more important than a2 and
a2 two times more important than a3 than he or she must consider a1 three times more
important than a3 If the judgment differs there is some inconsistency appraised by CR
(SAATY 1980) Anyway Hogart (1988) advise that we must count on some inconsistency in
mental models of deciders which must be reflected by the CR
5 Research
The research question was how can be understood and how to prioritize the various aspects
embedded in ecodesign practices in manufacture companies of the automotive industry The
answer must improve refute or correct the test hypotheses the presented method The main
objective of research was to test a method for prioritizing constructs in ecodesign practices in
an industry for the sake of reformulate strategic plans reinforcing practices judged more
important and eventually removing resources from those of less importance Secondary
objectives were (i) understand the emergence and practical implications of ecodesign
constructs in the industry and (ii) to distribute the relative weights (100 percentage points)
among the constructs A third objective is left for continuity (iii) to assess categorically the
actual situation of the constructs compare with priority and propose plans for those who have
biggest gaps between priority and performance The main contribution of the research is the
specific description of the case that added to others in growing depth and diversity may
expose regularities about the method and refine it
For questions containing the word how Yin (2009) indicates the case study method Case
studies can contribute exposing regularities that might be useful in formulating a theory about
the object (ECKSTEIN 1975) Repeated cases with similarities can contribute to the building
of a grounded theory (EISENHARDT 1989) Case studies in operations management are
acknowledged as a valid method for exploratory research like this (VOSS et al 2002) The
method aligns with the design research logic as stated by Hevner et al (2004) and Manson
(2006) According to this logic a method like we proposed can be thought of as a result of a
design process like producing a software package or a physical or logical artifact After a
mental or theoretical phase arises an idea that must be checked for viability and refined for
reliability in field cases (MARCH and SMITH 2005) like those here presented The authors
stress in the design research logic there are two important moments in the research the
mental or logical construction of the artifact and its refinement by field cases
51 Previous case understanding ecodesign in the automotive industry
The case took place in a mid-sized manufacturer with consolidated tradition in environmental
management and certified by both ISO 90012000 and ISO 140012004 normalization The
company produces on-board electronic components for vehicles The main research technique
was direct observation as well as interviewing the body of managers They began telling about
ecodesign in the industry as a hole and then about particularities of the company

The automotive industry operates in a highly competitive market with worldwide sale and
distribution The tolerance for product flaws is low especially in the case of vehicle safety
These factors can operate as constraints on the adoption of ecodesign practices by companies
in the industry Regarding natural resources the environmental balance for vehicles is
negative Production requires in raw material about ten times the weight of the car and uses
large amounts of water About forty thousand liters of water are required to manufacture a car
Vehicles consume fuel and lubricating oils most often from non-renewable fossil-based
resources sometimes returning as contaminants In addition cars use tires barely recycled
Moreover vehicles emit significant quantities of air pollutants including carbon dioxide (a
major greenhouse gas) and sulfur dioxide (which contributes to acid rain) Vehicles can also
be difficult to recycle at the end of their useful life They typically contain a variety of
different materials (including plastics and metals as well as electrical and electronic
components) that may be costly and challenging to separate
These impacts reinforce the perception that vehicles are not designed with an emphasis on
preserving the environment and promoting sustainability Partly in response to these concerns
the industry has developed high-performance and hybrid engines running on renewable bio-
fuels and using high-durability synthetic lubricating oils as well as has began using more
parts manufactured with recycled composite materials The industry is also seeking to restrict
the use of hazardous substances and to increase the quantity of returnable packaging and
materials These issues are particularly relevant in the European Union The EUrsquos RoHS
directive had banned the use of certain hazardous materials as constituents in specified parts
Regarding the company as its products involve special safety and security features it is not
allowed to reuse parts that could compromise reliability However raw materials such as
plastics and metals can be recycled The company has developed a complex business-to-
business relationship with its customers The company must meet applicable regulatory
requirements and also depends on customersrsquo approval in order to make changes to its
products When automotive assemblers qualify suppliers they primarily evaluate
characteristics such as reliability of deliver and products performance Suppliers also must
meet all relevant environmental requirements such as those related to restrictions on the use
of hazardous substances However exceeding minimal requirements does not constitute a
preferential or does not construct a competitive advantage factor for a given supplier So the
company has little autonomy in decisions involving introducing ecodesign practices in the
products and has little external compensation in doing so Prices politics are not influenced by
ecodesign practices in the automotive market at least until now
In spite of this the company addressed key issues regarding the environmental management
policy including energy and materials consumption and waste handling and treatment The
main drivers for ecodesign adoption was cost reduction due to dematerializing directives
(using the smallest possible amount of raw material) and to lowering expenditures related to
the treatment of waste The company formed a multidisciplinary group to handle the study
planning and strategic deployment of ecodesign techniques Top management organized a
working group that included people with expertise in relevant areas such as development
trade quality logistics and industrialization The group focused on activities related to the
development of products and processes implementing guidelines that included checklists for
design activities and product life-cycle assessment A huge difficulty was the shortage of
technical information available on environmental impacts of materials Using of standardized
databases is an alternative that the company now studies

Although the results are not yet those planned the body of managers recognized some
positive achievements costs reductions from dematerialization less manufactured products
due to multifunctionality implicating in less items in stock less test sets in the assembly line
less variety in the sales portfolio and higher lots of raw-materials purchased from a lower
number of suppliers reduction in costs due to waste disposal and transportation of raw-
materials
52 Next case prioritizing ecodesign in a company
The next case was developed in a chemical stuff manufactures that supply adhesives paints
greases and various liquid products to the automotive industry The company has several
families of products manufactured in multiple assembly lines and sites Design activities are
organized in teams with different requirements and practices Scarcely a technical
development or advance in one family of product can be extended to others but managerial
advances can be exchanged between groups Anyway due to the sharp differences between
design practices we chose two lines A and B to study Others can be addressed in the
continuity of the research
In focus groups sessions five experts in design for each family of product mediated by
researcher distributing relative weights among the constructs of ecodesign The prioritization
was made with the aid of the AHP In the first rounds calculated CR were nor proper so
researcher oriented experts to review flaws judgements until preference matrixes based on
more rational choices were achieved Experts produced the judgement matrixes of Tables 3
and 4 For the sake of clarity although the judgement did not employ this format we show
the preference matrixes with reorganized rows in decreasing order of importance As a clue
for checking out rationality in the preferences departing from the diagonal to the right side of
the matrix along the line one must find only increasing or at least equal numbers in
sequence If we find a decreasing number that means a flaw or incoherence in judgement

For the product A the most important construct in ecodesign is materials In fact due to its
chemical nature extraction warehousing and transportation of large quantities of A can
greatly affect quarries and its proximity and neighborhood of the manufacturer sites Using
alternate materials should be addressed in further redesign actions although experts stressed

11
they have little flexibility to change or use new materials due to consolidated technology and
assembly lines facilities For almost the same reasons the second construct in importance is
waste Due to the fact that half-life of the product is short and customers use little amount at a
time is not unusual that large amounts of the product must be discarded by end of usable life
This particularity turns wasting a problematic construct that must be focused in further actions
of redesign The third and fourth constructs are distribution and packaging with similar
priorities We stress that the distribution function includes not only the logistic operations of
transportation inspection and warehousing but also financial operations like assurance of
loads and people safety Packaging has still a significant importance due to the vast amount of
cardboard and wrapping plastic required most of them by no means easy for recycling or
reusing Components characteristics and energy usage have little priorities (lower than 10)
due to the particularities of the product and the manufacture process It requires no special
sub-systems to be assembled in the process is quite simple in little customized quantities and
exothermic what means that a part of the energy spent in it can be recovered and used
elsewhere in the site
Regarding to the judgement it was necessary more than one round but at the end experts
achieved a preference matrix with a very low inconsistency less than 1 meaning a
doubtless rational choice

For the product B as well as in A the most important construct in ecodesign is materials The
production is in bulk big lots but it is customized what means that the material leaves the
site with an assigned destination Exactly as with A due to chemical nature of the product
dependent of natural resources extraction warehousing and transportation can greatly affect
quarries and proximity of such installations and neighborhood of the manufacturer sites In
the same way using alternate materials should be addressed in further redesign actions Due
to similarities between the two products it can be worthwhile addressing unified actions
linking both products mainly regarding logistic operations Different from A the second
construct in importance for B is characteristics of product and process Process is quite
complicated and requires electronic equipment and feedback control in closed-loop fashion
which means maintenance efforts materials consumption and specialized people The process
is endothermic demanding a large amount of energy what explains the third construct in

importance usage of energy Distribution and packaging have similar particularities but
distribution is a little bit more demanding due to warehousing and inspections activities
required by the nature of the logistic operation Different from A waste has little importance
due mainly to the fact that almost always the total amount of the product is consumed in
automotive assemblers Half-life of the product is very long and just-in-time practices
required by assemblers do not allow over-production what assures little problems regarding
final disposals of wastings Regarding to residues well-succeeded experiments conducted in
thermal sites assure an environmental friendly destination contributing to energy generation
for further processes As well as in A no special sub-systems are required to be assembled in
so components are by no means a problem for designers
As in the product A the judgement required more than one round but at the end experts
achieved a preference matrix with a very low inconsistency less than 2 as well as the first
case meaning a doubtless rational choice
Figure 1 presents a graphical comparison between the two products We remark that materials
are the most priority construct in both products Although the teams were formed to work
separately in this case due to the importance of the construct and the similarities of the flaws
unified actions could be planned in order to reduce environmental pressures due to the
handling of materials mainly raw-materials

6 Final remarks
The main purpose of this article was to present a method for prioritizing constructs that
explains ecodesign practices in automotive industry Secondarily the article aimed at
understanding central aspects of ecodesign implementation and practical implications of
ecodesign in the industry and to distribute the relative weights (100 percentage points) among
the constructs in order to reach a prioritization structure A third objective was left for
continuity to assess the situation of the constructs and propose plans for those who have

biggest gaps between priority and performance The research method was the case study First
objective was achieved in a mid-sized supplier of electronic parts The second was achieved
in a chemical manufactures by analyzing two different families of products Due to the
method the main contribution of the research was the specific description of the cases and a
practical application of the prioritization method We stress that with the achievement of the
third objective a company should address the constructs with bigger gaps (the difference
between prioritization and performance) rather than those of higher prioritization
The method combined qualitative research techniques such as focus groups sessions with the
mathematical calculations used to find the vectors of priorities from the preference matrix It
was a limitation of the article the use of assessment based in expertsrsquo judgments opposite to
measurements based in physic conditions from field variates and mathematic models When
physic measurements are used further statistic considerations are necessary once usually the
measured variates are random In the other hand objectives measurement like those provided
by physical variates hold less subjectivity then categorical judgements
As continuity we propose the use of other multicriterial method beyond AHP It is also
suggested to test the method in another industry We also suggest assessment of performance
of the product in the constructs by means of a set of indicators that can explain the construct
So the reformulated actions would focus not necessarily in the most prioritized constructs
but in the constructs with larger gaps between priority and performance The method can also
be applied in the entire or at least a bigger part of the automotive chain The application
along the chain can identify the fragile parts on the ecodesign development and helps to focus
efforts in the chain At last it is proposed to integrate the method to the cleaner production
technologies and reversal logistic models available in literature It is understood that the
method might indicate the ecodesign gaps of a product operation and offer enough support to
the implementation and maintenance of cleaner production and reversal logistics programs in
manufacture in an on-going improvement basis

The top term the theoretical object is explained by latent constructs based on concepts
explained by indicators performing a tree-like structure in a hierarchical fashion of levels
The structure was built in previous research (BORCHARDT et al 2009b) and was built in
group sessions with scholars and praticants in environmental management and product
development mediated by researchers The leading edge was the works of Fiksel (1996)

The AHP (analytic hierarchic process) is well suited to prioritize constructs of a complex
object like ecodesign practices Wind and Saaty (1980) proposed that the AHP represents an
efficient method of dealing with complexity identifying and prioritizing the major

We calculate priorities by finding autovectors with maximum autovalues of matrix A Let A
be the comparison matrix (1) We must find the priorities vector w that satisfies (2)

For questions containing the word how Yin (2009) indicates the case study method Case
studies can contribute exposing regularities that might be useful in formulating a theory about
the object (ECKSTEIN 1975) Repeated cases with similarities can contribute to the building
of a grounded theory (EISENHARDT 1989) Case studies in operations management are
acknowledged as a valid method for exploratory research like this (VOSS et al 2002) The
method aligns with the design research logic as stated by Hevner et al (2004) and Manson
(2006) According to this logic a method like we proposed can be thought of as a result of a
design process like producing a software package or a physical or logical artifact After a
mental or theoretical phase arises an idea that must be checked for viability and refined for
reliability in field cases (MARCH and SMITH 2005) like those here presented The authors
stress in the design research logic there are two important moments in the research the
mental or logical construction of the artifact and its refinement by field cases
51 Previous case understanding ecodesign in the automotive industry
The case took place in a mid-sized manufacturer with consolidated tradition in environmental
management and certified by both ISO 90012000 and ISO 140012004 normalization The
company produces on-board electronic components for vehicles The main research technique
was direct observation as well as interviewing the body of managers They began telling about
ecodesign in the industry as a hole and then about particularities of the company

The automotive industry operates in a highly competitive market with worldwide sale and
distribution The tolerance for product flaws is low especially in the case of vehicle safety
These factors can operate as constraints on the adoption of ecodesign practices by companies
in the industry Regarding natural resources the environmental balance for vehicles is
negative Production requires in raw material about ten times the weight of the car and uses
large amounts of water About forty thousand liters of water are required to manufacture a car
Vehicles consume fuel and lubricating oils most often from non-renewable fossil-based
resources sometimes returning as contaminants In addition cars use tires barely recycled
Moreover vehicles emit significant quantities of air pollutants including carbon dioxide (a
major greenhouse gas) and sulfur dioxide (which contributes to acid rain) Vehicles can also
be difficult to recycle at the end of their useful life They typically contain a variety of
different materials (including plastics and metals as well as electrical and electronic
components) that may be costly and challenging to separate
These impacts reinforce the perception that vehicles are not designed with an emphasis on
preserving the environment and promoting sustainability Partly in response to these concerns
the industry has developed high-performance and hybrid engines running on renewable bio-
fuels and using high-durability synthetic lubricating oils as well as has began using more
parts manufactured with recycled composite materials The industry is also seeking to restrict
the use of hazardous substances and to increase the quantity of returnable packaging and
materials These issues are particularly relevant in the European Union The EUrsquos RoHS
directive had banned the use of certain hazardous materials as constituents in specified parts
Regarding the company as its products involve special safety and security features it is not
allowed to reuse parts that could compromise reliability However raw materials such as
plastics and metals can be recycled The company has developed a complex business-to-
business relationship with its customers The company must meet applicable regulatory
requirements and also depends on customersrsquo approval in order to make changes to its
products When automotive assemblers qualify suppliers they primarily evaluate
characteristics such as reliability of deliver and products performance Suppliers also must
meet all relevant environmental requirements such as those related to restrictions on the use
of hazardous substances However exceeding minimal requirements does not constitute a
preferential or does not construct a competitive advantage factor for a given supplier So the
company has little autonomy in decisions involving introducing ecodesign practices in the
products and has little external compensation in doing so Prices politics are not influenced by
ecodesign practices in the automotive market at least until now
In spite of this the company addressed key issues regarding the environmental management
policy including energy and materials consumption and waste handling and treatment The
main drivers for ecodesign adoption was cost reduction due to dematerializing directives
(using the smallest possible amount of raw material) and to lowering expenditures related to
the treatment of waste The company formed a multidisciplinary group to handle the study
planning and strategic deployment of ecodesign techniques Top management organized a
working group that included people with expertise in relevant areas such as development
trade quality logistics and industrialization The group focused on activities related to the
development of products and processes implementing guidelines that included checklists for
design activities and product life-cycle assessment A huge difficulty was the shortage of
technical information available on environmental impacts of materials Using of standardized
databases is an alternative that the company now studies

Although the results are not yet those planned the body of managers recognized some
positive achievements costs reductions from dematerialization less manufactured products
due to multifunctionality implicating in less items in stock less test sets in the assembly line
less variety in the sales portfolio and higher lots of raw-materials purchased from a lower
number of suppliers reduction in costs due to waste disposal and transportation of raw-
materials
52 Next case prioritizing ecodesign in a company
The next case was developed in a chemical stuff manufactures that supply adhesives paints
greases and various liquid products to the automotive industry The company has several
families of products manufactured in multiple assembly lines and sites Design activities are
organized in teams with different requirements and practices Scarcely a technical
development or advance in one family of product can be extended to others but managerial
advances can be exchanged between groups Anyway due to the sharp differences between
design practices we chose two lines A and B to study Others can be addressed in the
continuity of the research
In focus groups sessions five experts in design for each family of product mediated by
researcher distributing relative weights among the constructs of ecodesign The prioritization
was made with the aid of the AHP In the first rounds calculated CR were nor proper so
researcher oriented experts to review flaws judgements until preference matrixes based on
more rational choices were achieved Experts produced the judgement matrixes of Tables 3
and 4 For the sake of clarity although the judgement did not employ this format we show
the preference matrixes with reorganized rows in decreasing order of importance As a clue
for checking out rationality in the preferences departing from the diagonal to the right side of
the matrix along the line one must find only increasing or at least equal numbers in
sequence If we find a decreasing number that means a flaw or incoherence in judgement

For the product A the most important construct in ecodesign is materials In fact due to its
chemical nature extraction warehousing and transportation of large quantities of A can
greatly affect quarries and its proximity and neighborhood of the manufacturer sites Using
alternate materials should be addressed in further redesign actions although experts stressed

they have little flexibility to change or use new materials due to consolidated technology and
assembly lines facilities For almost the same reasons the second construct in importance is
waste Due to the fact that half-life of the product is short and customers use little amount at a
time is not unusual that large amounts of the product must be discarded by end of usable life
This particularity turns wasting a problematic construct that must be focused in further actions
of redesign The third and fourth constructs are distribution and packaging with similar
priorities We stress that the distribution function includes not only the logistic operations of
transportation inspection and warehousing but also financial operations like assurance of
loads and people safety Packaging has still a significant importance due to the vast amount of
cardboard and wrapping plastic required most of them by no means easy for recycling or
reusing Components characteristics and energy usage have little priorities (lower than 10)
due to the particularities of the product and the manufacture process It requires no special
sub-systems to be assembled in the process is quite simple in little customized quantities and
exothermic what means that a part of the energy spent in it can be recovered and used
elsewhere in the site
Regarding to the judgement it was necessary more than one round but at the end experts
achieved a preference matrix with a very low inconsistency less than 1 meaning a
doubtless rational choice

For the product B as well as in A the most important construct in ecodesign is materials The
production is in bulk big lots but it is customized what means that the material leaves the
site with an assigned destination Exactly as with A due to chemical nature of the product
dependent of natural resources extraction warehousing and transportation can greatly affect
quarries and proximity of such installations and neighborhood of the manufacturer sites In
the same way using alternate materials should be addressed in further redesign actions Due
to similarities between the two products it can be worthwhile addressing unified actions
linking both products mainly regarding logistic operations Different from A the second
construct in importance for B is characteristics of product and process Process is quite
complicated and requires electronic equipment and feedback control in closed-loop fashion
which means maintenance efforts materials consumption and specialized people The process
is endothermic demanding a large amount of energy what explains the third construct in

importance usage of energy Distribution and packaging have similar particularities but
distribution is a little bit more demanding due to warehousing and inspections activities
required by the nature of the logistic operation Different from A waste has little importance
due mainly to the fact that almost always the total amount of the product is consumed in
automotive assemblers Half-life of the product is very long and just-in-time practices
required by assemblers do not allow over-production what assures little problems regarding
final disposals of wastings Regarding to residues well-succeeded experiments conducted in
thermal sites assure an environmental friendly destination contributing to energy generation
for further processes As well as in A no special sub-systems are required to be assembled in
so components are by no means a problem for designers
As in the product A the judgement required more than one round but at the end experts
achieved a preference matrix with a very low inconsistency less than 2 as well as the first
case meaning a doubtless rational choice
Figure 1 presents a graphical comparison between the two products We remark that materials
are the most priority construct in both products Although the teams were formed to work
separately in this case due to the importance of the construct and the similarities of the flaws
unified actions could be planned in order to reduce environmental pressures due to the
handling of materials mainly raw-materials

6 Final remarks
The main purpose of this article was to present a method for prioritizing constructs that
explains ecodesign practices in automotive industry Secondarily the article aimed at
understanding central aspects of ecodesign implementation and practical implications of
ecodesign in the industry and to distribute the relative weights (100 percentage points) among
the constructs in order to reach a prioritization structure A third objective was left for
continuity to assess the situation of the constructs and propose plans for those who have

biggest gaps between priority and performance The research method was the case study First
objective was achieved in a mid-sized supplier of electronic parts The second was achieved
in a chemical manufactures by analyzing two different families of products Due to the
method the main contribution of the research was the specific description of the cases and a
practical application of the prioritization method We stress that with the achievement of the
third objective a company should address the constructs with bigger gaps (the difference
between prioritization and performance) rather than those of higher prioritization
The method combined qualitative research techniques such as focus groups sessions with the
mathematical calculations used to find the vectors of priorities from the preference matrix It
was a limitation of the article the use of assessment based in expertsrsquo judgments opposite to
measurements based in physic conditions from field variates and mathematic models When
physic measurements are used further statistic considerations are necessary once usually the
measured variates are random In the other hand objectives measurement like those provided
by physical variates hold less subjectivity then categorical judgements
As continuity we propose the use of other multicriterial method beyond AHP It is also
suggested to test the method in another industry We also suggest assessment of performance
of the product in the constructs by means of a set of indicators that can explain the construct
So the reformulated actions would focus not necessarily in the most prioritized constructs
but in the constructs with larger gaps between priority and performance The method can also
be applied in the entire or at least a bigger part of the automotive chain The application
along the chain can identify the fragile parts on the ecodesign development and helps to focus
efforts in the chain At last it is proposed to integrate the method to the cleaner production
technologies and reversal logistic models available in literature It is understood that the
method might indicate the ecodesign gaps of a product operation and offer enough support to
the implementation and maintenance of cleaner production and reversal logistics programs in
manufacture in an on-going improvement basis

The main purpose of this article was to present a method for prioritizing constructs that
explains ecodesign practices in automotive industry Secondarily the article aimed at
understanding central aspects of ecodesign implementation and practical implications of
ecodesign in the industry and to distribute the relative weights (100 percentage points) among
the constructs in order to reach a prioritization structure A third objective was left for

biggest gaps between priority and performance The research method was the case study First
objective was achieved in a mid-sized supplier of electronic parts The second was achieved
in a chemical manufactures by analyzing two different families of products Due to the
method the main contribution of the research was the specific description of the cases and a
practical application of the prioritization method We stress that with the achievement of the
third objective a company should address the constructs with bigger gaps (the difference
between prioritization and performance) rather than those of higher prioritization
The method combined qualitative research techniques such as focus groups sessions with the
mathematical calculations used to find the vectors of priorities from the preference matrix It
was a limitation of the article the use of assessment based in expertsrsquo judgments opposite to
measurements based in physic conditions from field variates and mathematic models When
physic measurements are used further statistic considerations are necessary once usually the
measured variates are random In the other hand objectives measurement like those provided
by physical variates hold less subjectivity then categorical judgements
As continuity we propose the use of other multicriterial method beyond AHP It is also
suggested to test the method in another industry We also suggest assessment of performance
of the product in the constructs by means of a set of indicators that can explain the construct
So the reformulated actions would focus not necessarily in the most prioritized constructs
but in the constructs with larger gaps between priority and performance The method can also
be applied in the entire or at least a bigger part of the automotive chain The application
along the chain can identify the fragile parts on the ecodesign development and helps to focus
efforts in the chain At last it is proposed to integrate the method to the cleaner production
technologies and reversal logistic models available in literature It is understood that the
method might indicate the ecodesign gaps of a product operation and offer enough support to
the implementation and maintenance of cleaner production and reversal logistics programs in
manufacture in an on-going improvement basis

If CR lt 10 the judgments can be considered satisfactory otherwise should be reviewed and
improved For instance if someone judges a1 one and a half times more important than a2 and
a2 two times more important than a3 than he or she must consider a1 three times more
important than a3 If the judgment differs there is some inconsistency appraised by CR
(SAATY 1980) Anyway Hogart (1988) advise that we must count on some inconsistency in
mental models of deciders which must be reflected by the CR
5 Research
The research question was how can be understood and how to prioritize the various aspects
embedded in ecodesign practices in manufacture companies of the automotive industry The
answer must improve refute or correct the test hypotheses the presented method The main
objective of research was to test a method for prioritizing constructs in ecodesign practices in
an industry for the sake of reformulate strategic plans reinforcing practices judged more
important and eventually removing resources from those of less importance Secondary
objectives were (i) understand the emergence and practical implications of ecodesign
constructs in the industry and (ii) to distribute the relative weights (100 percentage points)
among the constructs A third objective is left for continuity (iii) to assess categorically the
actual situation of the constructs compare with priority and propose plans for those who have
biggest gaps between priority and performance The main contribution of the research is the
specific description of the case that added to others in growing depth and diversity may
expose regularities about the method and refine it
For questions containing the word how Yin (2009) indicates the case study method Case
studies can contribute exposing regularities that might be useful in formulating a theory about
the object (ECKSTEIN 1975) Repeated cases with similarities can contribute to the building
of a grounded theory (EISENHARDT 1989) Case studies in operations management are
acknowledged as a valid method for exploratory research like this (VOSS et al 2002) The
method aligns with the design research logic as stated by Hevner et al (2004) and Manson
(2006) According to this logic a method like we proposed can be thought of as a result of a
design process like producing a software package or a physical or logical artifact After a
mental or theoretical phase arises an idea that must be checked for viability and refined for
reliability in field cases (MARCH and SMITH 2005) like those here presented The authors
stress in the design research logic there are two important moments in the research the
mental or logical construction of the artifact and its refinement by field cases
51 Previous case understanding ecodesign in the automotive industry
The case took place in a mid-sized manufacturer with consolidated tradition in environmental
management and certified by both ISO 90012000 and ISO 140012004 normalization The
company produces on-board electronic components for vehicles The main research technique
was direct observation as well as interviewing the body of managers They began telling about
ecodesign in the industry as a hole and then about particularities of the company

The automotive industry operates in a highly competitive market with worldwide sale and
distribution The tolerance for product flaws is low especially in the case of vehicle safety
These factors can operate as constraints on the adoption of ecodesign practices by companies
in the industry Regarding natural resources the environmental balance for vehicles is
negative Production requires in raw material about ten times the weight of the car and uses
large amounts of water About forty thousand liters of water are required to manufacture a car
Vehicles consume fuel and lubricating oils most often from non-renewable fossil-based
resources sometimes returning as contaminants In addition cars use tires barely recycled
Moreover vehicles emit significant quantities of air pollutants including carbon dioxide (a
major greenhouse gas) and sulfur dioxide (which contributes to acid rain) Vehicles can also
be difficult to recycle at the end of their useful life They typically contain a variety of
different materials (including plastics and metals as well as electrical and electronic
components) that may be costly and challenging to separate
These impacts reinforce the perception that vehicles are not designed with an emphasis on
preserving the environment and promoting sustainability Partly in response to these concerns
the industry has developed high-performance and hybrid engines running on renewable bio-
fuels and using high-durability synthetic lubricating oils as well as has began using more
parts manufactured with recycled composite materials The industry is also seeking to restrict
the use of hazardous substances and to increase the quantity of returnable packaging and
materials These issues are particularly relevant in the European Union The EUrsquos RoHS
directive had banned the use of certain hazardous materials as constituents in specified parts
Regarding the company as its products involve special safety and security features it is not
allowed to reuse parts that could compromise reliability However raw materials such as
plastics and metals can be recycled The company has developed a complex business-to-
business relationship with its customers The company must meet applicable regulatory
requirements and also depends on customersrsquo approval in order to make changes to its
products When automotive assemblers qualify suppliers they primarily evaluate
characteristics such as reliability of deliver and products performance Suppliers also must
meet all relevant environmental requirements such as those related to restrictions on the use
of hazardous substances However exceeding minimal requirements does not constitute a
preferential or does not construct a competitive advantage factor for a given supplier So the
company has little autonomy in decisions involving introducing ecodesign practices in the
products and has little external compensation in doing so Prices politics are not influenced by
ecodesign practices in the automotive market at least until now
In spite of this the company addressed key issues regarding the environmental management
policy including energy and materials consumption and waste handling and treatment The
main drivers for ecodesign adoption was cost reduction due to dematerializing directives
(using the smallest possible amount of raw material) and to lowering expenditures related to
the treatment of waste The company formed a multidisciplinary group to handle the study
planning and strategic deployment of ecodesign techniques Top management organized a
working group that included people with expertise in relevant areas such as development
trade quality logistics and industrialization The group focused on activities related to the
development of products and processes implementing guidelines that included checklists for
design activities and product life-cycle assessment A huge difficulty was the shortage of
technical information available on environmental impacts of materials Using of standardized
databases is an alternative that the company now studies

Although the results are not yet those planned the body of managers recognized some
positive achievements costs reductions from dematerialization less manufactured products
due to multifunctionality implicating in less items in stock less test sets in the assembly line
less variety in the sales portfolio and higher lots of raw-materials purchased from a lower
number of suppliers reduction in costs due to waste disposal and transportation of raw-
materials
52 Next case prioritizing ecodesign in a company
The next case was developed in a chemical stuff manufactures that supply adhesives paints
greases and various liquid products to the automotive industry The company has several
families of products manufactured in multiple assembly lines and sites Design activities are
organized in teams with different requirements and practices Scarcely a technical
development or advance in one family of product can be extended to others but managerial
advances can be exchanged between groups Anyway due to the sharp differences between
design practices we chose two lines A and B to study Others can be addressed in the
continuity of the research
In focus groups sessions five experts in design for each family of product mediated by
researcher distributing relative weights among the constructs of ecodesign The prioritization
was made with the aid of the AHP In the first rounds calculated CR were nor proper so
researcher oriented experts to review flaws judgements until preference matrixes based on
more rational choices were achieved Experts produced the judgement matrixes of Tables 3
and 4 For the sake of clarity although the judgement did not employ this format we show
the preference matrixes with reorganized rows in decreasing order of importance As a clue
for checking out rationality in the preferences departing from the diagonal to the right side of
the matrix along the line one must find only increasing or at least equal numbers in
sequence If we find a decreasing number that means a flaw or incoherence in judgement

physic measurements are used further statistic considerations are necessary once usually the
measured variates are random In the other hand objectives measurement like those provided
by physical variates hold less subjectivity then categorical judgements
As continuity we propose the use of other multicriterial method beyond AHP It is also
suggested to test the method in another industry We also suggest assessment of performance
of the product in the constructs by means of a set of indicators that can explain the construct
So the reformulated actions would focus not necessarily in the most prioritized constructs
but in the constructs with larger gaps between priority and performance The method can also
be applied in the entire or at least a bigger part of the automotive chain The application
along the chain can identify the fragile parts on the ecodesign development and helps to focus
efforts in the chain At last it is proposed to integrate the method to the cleaner production
technologies and reversal logistic models available in literature It is understood that the
method might indicate the ecodesign gaps of a product operation and offer enough support to
the implementation and maintenance of cleaner production and reversal logistics programs in
manufacture in an on-going improvement basis

The automotive industry operates in a highly competitive market with worldwide sale and
distribution The tolerance for product flaws is low especially in the case of vehicle safety
These factors can operate as constraints on the adoption of ecodesign practices by companies
in the industry Regarding natural resources the environmental balance for vehicles is
negative Production requires in raw material about ten times the weight of the car and uses
large amounts of water About forty thousand liters of water are required to manufacture a car
Vehicles consume fuel and lubricating oils most often from non-renewable fossil-based
resources sometimes returning as contaminants In addition cars use tires barely recycled
Moreover vehicles emit significant quantities of air pollutants including carbon dioxide (a
major greenhouse gas) and sulfur dioxide (which contributes to acid rain) Vehicles can also
be difficult to recycle at the end of their useful life They typically contain a variety of
different materials (including plastics and metals as well as electrical and electronic
components) that may be costly and challenging to separate
These impacts reinforce the perception that vehicles are not designed with an emphasis on
preserving the environment and promoting sustainability Partly in response to these concerns
the industry has developed high-performance and hybrid engines running on renewable bio-
fuels and using high-durability synthetic lubricating oils as well as has began using more
parts manufactured with recycled composite materials The industry is also seeking to restrict
the use of hazardous substances and to increase the quantity of returnable packaging and
materials These issues are particularly relevant in the European Union The EUrsquos RoHS
directive had banned the use of certain hazardous materials as constituents in specified parts
Regarding the company as its products involve special safety and security features it is not
allowed to reuse parts that could compromise reliability However raw materials such as
plastics and metals can be recycled The company has developed a complex business-to-
business relationship with its customers The company must meet applicable regulatory
requirements and also depends on customersrsquo approval in order to make changes to its
products When automotive assemblers qualify suppliers they primarily evaluate
characteristics such as reliability of deliver and products performance Suppliers also must
meet all relevant environmental requirements such as those related to restrictions on the use
of hazardous substances However exceeding minimal requirements does not constitute a
preferential or does not construct a competitive advantage factor for a given supplier So the
company has little autonomy in decisions involving introducing ecodesign practices in the
products and has little external compensation in doing so Prices politics are not influenced by
ecodesign practices in the automotive market at least until now
In spite of this the company addressed key issues regarding the environmental management
policy including energy and materials consumption and waste handling and treatment The
main drivers for ecodesign adoption was cost reduction due to dematerializing directives
(using the smallest possible amount of raw material) and to lowering expenditures related to
the treatment of waste The company formed a multidisciplinary group to handle the study
planning and strategic deployment of ecodesign techniques Top management organized a
working group that included people with expertise in relevant areas such as development
trade quality logistics and industrialization The group focused on activities related to the
development of products and processes implementing guidelines that included checklists for
design activities and product life-cycle assessment A huge difficulty was the shortage of
technical information available on environmental impacts of materials Using of standardized
databases is an alternative that the company now studies

Although the results are not yet those planned the body of managers recognized some
positive achievements costs reductions from dematerialization less manufactured products
due to multifunctionality implicating in less items in stock less test sets in the assembly line
less variety in the sales portfolio and higher lots of raw-materials purchased from a lower
number of suppliers reduction in costs due to waste disposal and transportation of raw-
materials
52 Next case prioritizing ecodesign in a company
The next case was developed in a chemical stuff manufactures that supply adhesives paints
greases and various liquid products to the automotive industry The company has several
families of products manufactured in multiple assembly lines and sites Design activities are
organized in teams with different requirements and practices Scarcely a technical
development or advance in one family of product can be extended to others but managerial
advances can be exchanged between groups Anyway due to the sharp differences between
design practices we chose two lines A and B to study Others can be addressed in the
continuity of the research
In focus groups sessions five experts in design for each family of product mediated by
researcher distributing relative weights among the constructs of ecodesign The prioritization
was made with the aid of the AHP In the first rounds calculated CR were nor proper so
researcher oriented experts to review flaws judgements until preference matrixes based on
more rational choices were achieved Experts produced the judgement matrixes of Tables 3
and 4 For the sake of clarity although the judgement did not employ this format we show
the preference matrixes with reorganized rows in decreasing order of importance As a clue
for checking out rationality in the preferences departing from the diagonal to the right side of
the matrix along the line one must find only increasing or at least equal numbers in
sequence If we find a decreasing number that means a flaw or incoherence in judgement

For the product A the most important construct in ecodesign is materials In fact due to its
chemical nature extraction warehousing and transportation of large quantities of A can
greatly affect quarries and its proximity and neighborhood of the manufacturer sites Using
alternate materials should be addressed in further redesign actions although experts stressed

they have little flexibility to change or use new materials due to consolidated technology and
assembly lines facilities For almost the same reasons the second construct in importance is
waste Due to the fact that half-life of the product is short and customers use little amount at a
time is not unusual that large amounts of the product must be discarded by end of usable life
This particularity turns wasting a problematic construct that must be focused in further actions
of redesign The third and fourth constructs are distribution and packaging with similar
priorities We stress that the distribution function includes not only the logistic operations of
transportation inspection and warehousing but also financial operations like assurance of
loads and people safety Packaging has still a significant importance due to the vast amount of
cardboard and wrapping plastic required most of them by no means easy for recycling or
reusing Components characteristics and energy usage have little priorities (lower than 10)
due to the particularities of the product and the manufacture process It requires no special
sub-systems to be assembled in the process is quite simple in little customized quantities and
exothermic what means that a part of the energy spent in it can be recovered and used
elsewhere in the site
Regarding to the judgement it was necessary more than one round but at the end experts
achieved a preference matrix with a very low inconsistency less than 1 meaning a
doubtless rational choice

For the product B as well as in A the most important construct in ecodesign is materials The
production is in bulk big lots but it is customized what means that the material leaves the
site with an assigned destination Exactly as with A due to chemical nature of the product
dependent of natural resources extraction warehousing and transportation can greatly affect
quarries and proximity of such installations and neighborhood of the manufacturer sites In
the same way using alternate materials should be addressed in further redesign actions Due
to similarities between the two products it can be worthwhile addressing unified actions
linking both products mainly regarding logistic operations Different from A the second
construct in importance for B is characteristics of product and process Process is quite
complicated and requires electronic equipment and feedback control in closed-loop fashion
which means maintenance efforts materials consumption and specialized people The process
is endothermic demanding a large amount of energy what explains the third construct in

importance usage of energy Distribution and packaging have similar particularities but
distribution is a little bit more demanding due to warehousing and inspections activities
required by the nature of the logistic operation Different from A waste has little importance
due mainly to the fact that almost always the total amount of the product is consumed in
automotive assemblers Half-life of the product is very long and just-in-time practices
required by assemblers do not allow over-production what assures little problems regarding
final disposals of wastings Regarding to residues well-succeeded experiments conducted in
thermal sites assure an environmental friendly destination contributing to energy generation
for further processes As well as in A no special sub-systems are required to be assembled in
so components are by no means a problem for designers
As in the product A the judgement required more than one round but at the end experts
achieved a preference matrix with a very low inconsistency less than 2 as well as the first
case meaning a doubtless rational choice
Figure 1 presents a graphical comparison between the two products We remark that materials
are the most priority construct in both products Although the teams were formed to work
separately in this case due to the importance of the construct and the similarities of the flaws
unified actions could be planned in order to reduce environmental pressures due to the
handling of materials mainly raw-materials

6 Final remarks
The main purpose of this article was to present a method for prioritizing constructs that
explains ecodesign practices in automotive industry Secondarily the article aimed at
understanding central aspects of ecodesign implementation and practical implications of
ecodesign in the industry and to distribute the relative weights (100 percentage points) among
the constructs in order to reach a prioritization structure A third objective was left for
continuity to assess the situation of the constructs and propose plans for those who have

biggest gaps between priority and performance The research method was the case study First
objective was achieved in a mid-sized supplier of electronic parts The second was achieved
in a chemical manufactures by analyzing two different families of products Due to the
method the main contribution of the research was the specific description of the cases and a
practical application of the prioritization method We stress that with the achievement of the
third objective a company should address the constructs with bigger gaps (the difference
between prioritization and performance) rather than those of higher prioritization
The method combined qualitative research techniques such as focus groups sessions with the
mathematical calculations used to find the vectors of priorities from the preference matrix It
was a limitation of the article the use of assessment based in expertsrsquo judgments opposite to
measurements based in physic conditions from field variates and mathematic models When
physic measurements are used further statistic considerations are necessary once usually the
measured variates are random In the other hand objectives measurement like those provided
by physical variates hold less subjectivity then categorical judgements
As continuity we propose the use of other multicriterial method beyond AHP It is also
suggested to test the method in another industry We also suggest assessment of performance
of the product in the constructs by means of a set of indicators that can explain the construct
So the reformulated actions would focus not necessarily in the most prioritized constructs
but in the constructs with larger gaps between priority and performance The method can also
be applied in the entire or at least a bigger part of the automotive chain The application
along the chain can identify the fragile parts on the ecodesign development and helps to focus
efforts in the chain At last it is proposed to integrate the method to the cleaner production
technologies and reversal logistic models available in literature It is understood that the
method might indicate the ecodesign gaps of a product operation and offer enough support to
the implementation and maintenance of cleaner production and reversal logistics programs in
manufacture in an on-going improvement basis

distribution is a little bit more demanding due to warehousing and inspections activities
required by the nature of the logistic operation Different from A waste has little importance
due mainly to the fact that almost always the total amount of the product is consumed in
automotive assemblers Half-life of the product is very long and just-in-time practices
required by assemblers do not allow over-production what assures little problems regarding
final disposals of wastings Regarding to residues well-succeeded experiments conducted in
thermal sites assure an environmental friendly destination contributing to energy generation
for further processes As well as in A no special sub-systems are required to be assembled in

achieved a preference matrix with a very low inconsistency less than 2 as well as the first

Figure 1 presents a graphical comparison between the two products We remark that materials
are the most priority construct in both products Although the teams were formed to work
separately in this case due to the importance of the construct and the similarities of the flaws

6 Final remarks
The main purpose of this article was to present a method for prioritizing constructs that
explains ecodesign practices in automotive industry Secondarily the article aimed at
understanding central aspects of ecodesign implementation and practical implications of
ecodesign in the industry and to distribute the relative weights (100 percentage points) among
the constructs in order to reach a prioritization structure A third objective was left for
continuity to assess the situation of the constructs and propose plans for those who have

biggest gaps between priority and performance The research method was the case study First
objective was achieved in a mid-sized supplier of electronic parts The second was achieved
in a chemical manufactures by analyzing two different families of products Due to the
method the main contribution of the research was the specific description of the cases and a
practical application of the prioritization method We stress that with the achievement of the
third objective a company should address the constructs with bigger gaps (the difference
between prioritization and performance) rather than those of higher prioritization
The method combined qualitative research techniques such as focus groups sessions with the
mathematical calculations used to find the vectors of priorities from the preference matrix It
was a limitation of the article the use of assessment based in expertsrsquo judgments opposite to
measurements based in physic conditions from field variates and mathematic models When
physic measurements are used further statistic considerations are necessary once usually the
measured variates are random In the other hand objectives measurement like those provided
by physical variates hold less subjectivity then categorical judgements
As continuity we propose the use of other multicriterial method beyond AHP It is also
suggested to test the method in another industry We also suggest assessment of performance
of the product in the constructs by means of a set of indicators that can explain the construct
So the reformulated actions would focus not necessarily in the most prioritized constructs
but in the constructs with larger gaps between priority and performance The method can also
be applied in the entire or at least a bigger part of the automotive chain The application
along the chain can identify the fragile parts on the ecodesign development and helps to focus
efforts in the chain At last it is proposed to integrate the method to the cleaner production
technologies and reversal logistic models available in literature It is understood that the
method might indicate the ecodesign gaps of a product operation and offer enough support to
the implementation and maintenance of cleaner production and reversal logistics programs in
manufacture in an on-going improvement basis

they have little flexibility to change or use new materials due to consolidated technology and
assembly lines facilities For almost the same reasons the second construct in importance is
waste Due to the fact that half-life of the product is short and customers use little amount at a
time is not unusual that large amounts of the product must be discarded by end of usable life
This particularity turns wasting a problematic construct that must be focused in further actions
of redesign The third and fourth constructs are distribution and packaging with similar
priorities We stress that the distribution function includes not only the logistic operations of
transportation inspection and warehousing but also financial operations like assurance of
loads and people safety Packaging has still a significant importance due to the vast amount of
cardboard and wrapping plastic required most of them by no means easy for recycling or
reusing Components characteristics and energy usage have little priorities (lower than 10)

biggest gaps between priority and performance The research method was the case study First
objective was achieved in a mid-sized supplier of electronic parts The second was achieved
in a chemical manufactures by analyzing two different families of products Due to the
method the main contribution of the research was the specific description of the cases and a
practical application of the prioritization method We stress that with the achievement of the
third objective a company should address the constructs with bigger gaps (the difference
between prioritization and performance) rather than those of higher prioritization
The method combined qualitative research techniques such as focus groups sessions with the
mathematical calculations used to find the vectors of priorities from the preference matrix It
was a limitation of the article the use of assessment based in expertsrsquo judgments opposite to
measurements based in physic conditions from field variates and mathematic models When
physic measurements are used further statistic considerations are necessary once usually the
measured variates are random In the other hand objectives measurement like those provided
by physical variates hold less subjectivity then categorical judgements
As continuity we propose the use of other multicriterial method beyond AHP It is also
suggested to test the method in another industry We also suggest assessment of performance
of the product in the constructs by means of a set of indicators that can explain the construct
So the reformulated actions would focus not necessarily in the most prioritized constructs
but in the constructs with larger gaps between priority and performance The method can also
be applied in the entire or at least a bigger part of the automotive chain The application
along the chain can identify the fragile parts on the ecodesign development and helps to focus
efforts in the chain At last it is proposed to integrate the method to the cleaner production
technologies and reversal logistic models available in literature It is understood that the
method might indicate the ecodesign gaps of a product operation and offer enough support to
the implementation and maintenance of cleaner production and reversal logistics programs in
manufacture in an on-going improvement basis
