Current Situation and Economic Feasibility of e-Waste Recycling in Morocco
A
Executive Summary
On a global scale, the strong increase in consumption of electric and electronic equipment (EEE) leads to
growing volumes of e-waste. This trend is boosted by the shortening lifetimes of IT equipment due to its fast
technological development, too. To tackle this waste stream, the Deutsche Gesellschaft fr Internationale
Zusammenarbeit (GIZ) and Hewlett-Packard (HP) launched into a Public-Private Partnership that aims for a
sustainable e-waste management in selected African countries, amongst others Morocco. Within the scope
of this PPP, the Swiss Federal Laboratories for Materials Science and Technology (Empa) were engaged by
HP to assess the current situation and the financial viability of e-waste recycling in Morocco. The present
study bases on two previous studies from Rochat and Laissaoui (2008) and GIZ (2010), the latter being
carried out within the framework of this PPP.
It is estimated that in 2008 roughly 40000 tons of obsolete IT equipment and consumer goods weregenerated in Morocco (EU-WEEE categories 3 & 4). Apparently, this volume is generated almost exclusively
by domestic consumption as no evidence of imports of larger quantities of e-waste or second-hand
appliances was found. Despite this considerable volume of obsolete appliances, no adequate e-waste
management is in place so far. E.g. for households, no collection alternative is available. Contrary to
experiences in other African countries, scavengers from the informal sector that collect waste in the streets
dont seem to focus on e-waste (door-to-door collection). For companies and authorities, few e-waste
collection channels exist. Usually, the appliances are provided to recyclers primarily by tender offers or
less frequently donations. The lack of required standards for the e-waste treatment leads to a
discrimination of formal recyclers with sound operations in favour of informal stakeholders in tender offers.
The interest in e-waste among stakeholders in Morocco is growing. Even though the treated volumes are
small, several companies or NGOs are currently dismantling e-waste. Apart from metal refining options (e.g.
Fe, Cu), no national sound solutions for downstream processing are available for most fractions generated
during dismantling. However, for some special fractions national refining options are evolving, e.g. for CRT
monitors. For other fractions, such as precious metals containing printed wiring boards, treatment options
abroad still seems to be advantageous, as currently the global players can guarantee better environmentally
compliance and maximized recovery of valuable materials and thus also better business performance.
To date, no Moroccan legislation exists that tackles the e-waste management specifically. It is loosely
regulated by law 28-00 that covers waste management in general. Morocco is signatory state of the Basel
Convention on the Control of Transboundary Movements of Hazardous Wastes and their Disposal .
Within the scope of the study, an MS Excel-based model was developed to perform a sensitivity analysis of
the business performance of a model dismantling facility. Results suggest that a business model which relies
solely on the income generated by the intrinsic value of the treated material is feasible. However, in none of
the calculated scenarios the break-even is expected to be reached below a treated volume of 500 tonnes per
year. Hence an effective collection system is a precondition for a successful recycling business.

Dependency of business performance on the amount of
WEEE treated at different commodi ty prices 2004 2010.
The short and long term profitability of the business model depends on a multitude of parameters, which
entail both opportunities and threats. Commodity prices have the strongest impact on the business
performance and pose a relevant risk to the business (see figure above). Due to a different material
composition of specific appliances, the appliance scope which is received by the business are financially
relevant, too. While the treatment of IT equipment including CRT monitors generates a sufficient revenue
with adequate volumes treated, the treatment of TVs is more likely to burden the business financially.
Including reuse and refurbishment in the model calculation suggests that this supplementary activity can add
financial benefits. However, to better assess opportunities and threats associated to reuse and
refurbishment, the calculations should be put on a more reliable data basis.
Although the model results suggest that, currently, e-waste recycling businesses in Morocco can be run by
relying on the intrinsic value of the treated material only, changing conditions can pose relevant risks to the
business. It is therefore concluded that sustainable recycling businesses can only grow in Morocco in
combination with a comprehensive framework, which ensures:
1. that business sustainability is also guaranteed under unfavourable economic conditions, i.e. an
additional flexible income stream enabled through a financing scheme needs to be established for
situations where the intrinsic value of the treated material is not sufficient for a break-even;
2. that recycling businesses can grow in a level playing field; i.e. that legislation, as well as monitoring
and control mechanisms favour high standard operations;
3. that market incentive are set such as high collection and recycling rates are encouraged.
At the absence of a financing scheme, a level playing field and the right market incentive it is likely that
recyclers will not be interested in investing into sound operations and that cherry picking activities with low
environmental and social performance as well as low collection and material recovery rates will prevail the
situation in Morocco.

The producer of hazardous waste and the legal personality possessing an authorization
according to Art. 30 and 35 has to keep a record about the quantities, the type and the
origin of the hazardous waste they are working with (Art. 37).
Law 28-00 prohibits the importation of hazardous waste, thus the importation of e-waste, too.
Furthermore, on 9 July 2008, decree N 2-07-253 (Catalogue marocain des dchets), which is
based on law 28-00, was enacted. This Moroccan waste catalogue is principally adopted from the
European Waste Catalogue and the Basel Convention (see chapter 2.1.4). The section concerning
WEEE of the Moroccan catalogue is provided in appendix 6.
Law N 12-03 on environmental impact s tudies (enacted on 12 May 2003)
Any new project or extension of an existing project for the recycling or disposal of WEEE is subject
to an environmental impact study.
2.1.2 Transportation Restric tions
Since several national and international regulations affect the transport of waste, a short summary
concerning transportation is provided here. As most operations with e-waste, also its transportation
regulation is dependent on the classification of e-waste as hazardous or non-hazardous,
respectively. For further information about this classification, see above (chapter 2.1.1).
2.1.2.1 National
The decree N 2-04-4684stipulates that any parcel (french: colis) weighing more than 1 ton has to
be provided with information about its weight, the nature of its content, the minimal length of the
parcel, the position of the loading and the name of its sender. The decree is specifying the article
302 in the Moroccan labour code.
For non-hazardous wastes, no specific regulation on transportation exists. Only law 28-00
delineates by article 26 the mixing of those wastes with domestic wastes:
Les dchets agricoles et les dchets industriels non dangereux ne peuvent tre assimils aux
dchets mnagers que sur la base dun rapport danalyse exig, en cas de ncessit, par la
commune et labor par un laboratoire agr. Dans ce cas, ces dchets peuvent tre transports
et dposs dans des endroits spars au sein des dcharges contrles des dchets mnagers et
assimils.
In terms of hazardous waste, law 28-00 imposes the conditions specified in chapter 2.1.1 on
transportation. Especially the articles 30 - 32 and 35 - 37 are relevant with regard to transportation
(see above).

Morocco accessed the Basel Convention in 1996 and implemented it in the law 28-00 (Art. 42 -
47).
As a supplement to the Basel Convention, the Ban Amendment7 prohibits hazardous waste
exports from Annex VII countries (Basel Convention countries that are member of the EU, OECD,
Liechtenstein) to non-Annex VII countries (all other Parties of the Convention). Morocco ratified the
Ban Amendment in 2004. It is important to note that this amendment has not yet entered into force(3/4 of the Parties who accepted it have to ratify it).
Another international treaty affecting the handling of e-waste is the Stockholm Convention on
Persistant Organic Pollutants(POPs)8, which was ratified by Morocco in 2004. It obligates the
signatory countries to establish the needed measures to prohibit the production, utilization, import
and export of POPs (e.g. PCB).
2.2 Required Standards by HP
HP established its own guidelines which each vendor of HP has to comply with. Within the scope
of e-waste recycling, mainly three documents specify those guidelines:
Electronic Industry Code of Conduct9(HP 2009),
Supplier Social & Environmental Responsibility Agreement10and
HP Standard 007-2 Vendor Requirements for Hardware Recycling11(HP 2008a).
Furthermore, the HP Standard 007-3 delineates the requirements for hardware reuse12 (HP
2008b).
The guidelines by HP are not only directed to the first level vendors, but also to the (sub-)vendorsengaged in any of the following associated activities: handling, storage, transportation, and
processing. They range from EHS to operational to social issues a (sub-)vendor should consider.
Thereby, the first level vendors are accountable for the compliance of their sub-vendors with the
HP guidelines. In general, HP requires that vendors obtain and maintain all applicable permits,
licenses, approvals, agreements, and other required government or regulatory documents. (HP
2008a)
It is important to note that those guidelines and standards do not only apply for vendors of the
industrialized world, but to all vendors which treat HP products. However, due to less supportive
framework conditions (lacking infrastructure, no specific legislation, etc.) in developing countries, agradual implementation of those standards in e.g. Morocco is possible. HP currently is following
such an approach in South Africa.

Hereafter, a compilation of the most relevant HP specifications is given. For further details, please
consult the original guidelines mentioned.
2.2.1 Reuse, Resale, or Donation of Whole Units , Parts, or Components
The vendor must provide assurance that all of the products sold are in working condition by testing
them and documenting this process (HP 2008a). More details are provided in HP Standard 007-3
(HP 2008b, see above).
2.2.2 Landfill Avoidance and Corresponding Approved Dispositions
The following products and components must not be land-filled: whole monitors; central
processing units (CPUs); televisions; printers; printed circuit boards containing lead; mercury
lamps and switches; cathode ray tubes (CRTs); CRT glass; batteries; liquid crystal displays(LCDs); plasma screens; and any materials containing lead, mercury, cadmium, hexavalent
chromium, or polychlorinated biphenyls (PCBs). (HP 2008a)
For the majority of those products and components, HP provides specification on their approved
disposition:
Mercury lamps must be processed by vendors capable of and experienced in handling
and recycling mercury. The mercury-containing components must be recovered and not be
sent to landfills.
Batteries must be processed by vendors capable of and experienced in recovering andrecycling lead, acid, cadmium, nickel, copper, zinc, and other metals present in batteries.
CRTs(cathode ray tubes) must be processed by a leaded-glass recycler or a lead smelter.
LCDs(liquid crystal displays) must be processed by vendors capable of and experienced in
recovering mercury in backlights.
PC (printed circuit) boardsmust be processed by a smelter (or other thermal process)
capable of and experienced in recovering precious metals (gold and so forth) and heavy
metals (lead and so forth) for reuse or by a chemical recovery process. Circuit components
may be extracted for reuse prior to smelting.
Plastics should be recycled for use in new products, components and materials, as
substitutes for other raw materials, or recycled in another beneficial manner. When
recycling is not economically practical, plastics should be processed for energy recovery at
a facility that is designed to control and monitor emissions from the process. See section
14.9 for related information.
Printing suppliescollected as part of hardware recycling (for example, a print cartridge
present in a printer at the time of its collection): Original HP printer cartridges must be
processed using the HP Inkjet cartridge and LaserJet toner cartridge return and recycling
programs in countries where HP programs are available. All other print supplies must be

recycled or disposed of in an environmentally responsible manner compliant with applicable
laws and regulations.
Metal(other than in PC boards):Acceptable processing includes liberation of metal items
(manually or mechanically), volume reduction for transport (shredding, baling, and so forth),
and refining by smelters or foundries (or similar) for the purpose of preparing the metal for
reuse. To maximize recycling rates, sending whole products to a smelter is not authorizedwithout approval from HP and demonstration that the smelter is capable of capturing all of
the following for reuse: copper, precious metals (such as gold and silver); steel and
aluminum; and, for CRT devices, lead.
Incineration: If lead-bearing electronic components (such as circuit boards), batteries,
polyvinyl chloride (PVC) plastics, mercury lamps, or any material classified as hazardous
waste under applicable regulations are disposed of by incineration, the incinerator must
meet 99.99% destruction removal efficiency (DRE) for all regulated hazardous
contaminants and 99.9999% DRE for dioxins.
Other Dispositions: Any other disposition for the above materials is not authorized unless
approved in advance by HP. (HP 2008a)
2.2.3 Information Security
All data-containing devices such as hard drives, and recording media such as CDs, DVDs, tapes,
or other similar items must either be fully erased or destroyed by shredding, crushing, shearing,
melting, incinerating, or perforating the memory resident material. (HP 2008a)
2.2.4 Transportation
With respect to international transportation, HP (2008a) stipulates:
HP products, components or materials exported across country borders must have prior
approval from the HP vendor manager,
any required permits or government consents for transboundary shipments must be
secured before shipment, and
hazardous or regulated materials shall not be exported from developed countries to
developing countries.
2.2.5 Health & Safety
The HP Standards on H&S are generally based on recognized management systems such as
OHSAS 1800113and ILO Guidelines14on Occupational Safety and Health.

The employer has to guarantee the
provision with drinking water at the
workplace and ensure salubrious housing
and satisfying hygiene conditions for the
workers (Art. 281).
Sanitation, food, housing: workers are to be
provided with ready access to clean toilet
facilities, potable water and sanitary food
preparation, storage, and eating facilities.
[]
2.2.6 Other Specifications
Among others, further requirements within the HP Standards for Hardware Recycling (HP 2008a)
are:
Emergency plans: the vendors have to implement and maintain an emergency response
plan to prepare for and respond to emergency situations, including fires, medical
emergencies, and uncontrolled releases of hazardous or harmful materials.
Insurance: each vendor has to maintain a general liability, a comprehensive liability and a
pollution liability insurance.
Use of subvendors: Vendors must verify and maintain documentation that any
subvendors they employ to provide recycling or disposal services for designated materials
originating from HP will and do comply with this standard, including the HP Supplier Code
of Conduct.Vendors must conduct audits to document conformance to HP standards at
all subvendor sites and operations, regardless of their locations, that are used for handling,
storage, or processing designated materials managed on behalf of HP.
Audi ts : HP reserves the right to conduct annual audits and assessments of all vendorsites and operations []
Product and Materials Tracking and Accountability: Upon request, vendors must
provide an accounting to HP of all HP products, components, and materials they have
processed []
Site security: Security controls must be in place to protect HP products, components, and
materials from the time entrusted to the vendor This concerns also the employees, which
have to be screened for criminal convictions (unless prohibited by law) before assigning
any employee or contractor work or access to HP products or components.

2.3 Recycler and Refiner
An economically efficient and environmentally sound e-waste business not only relies upon the
single processing steps but on the recycling chain as a whole. Each step in this chain is interlinked
with the precedent and following step, e.g. the composition of the collected waste material
determines the design of the processing channel. A proper coordination of the whole recycling
chain and a transparent and close interaction and communication are thus crucial to achieve a
good overall efficiency (Schluep et al. 2009).
The necessary investments and technological requirements for the respective steps in the e-waste
recycling chain differ significantly. As a consequence an international division of labor has been
established over time. Collection, dismantling and partly mechanical pre-processing takes place at
a national or regional level, as does metals recovery from less complex materials/fractions such as
ferrous, copper and aluminum. On the contrary treatment of complex materials such as circuit
boards, batteries, cell phones in refining processes or specialized battery recycling plants takes
place in a global context. (Schluep et al. 2009)
Information about some special fractions which have to be processed can be found in chapter
3.1.8.

In this chapter, an outline of the present e-waste recycler and refiner of the fractions generated
during pre-processing on a national and international scale is given. The purpose is to dispose of
an information basis allowing the design of recycling concepts adapted to the local circumstances
and the identification of required extensions and/or improvements in the recycling chain.

informal sector is allowed to compete as well. Due to their cherry-picking approach15, they readily
outcompete formal recyclers. A field visit at the facility close to Berrechid (Greater Casablanca)
revealed that e-waste makes only a small share of the whole material throughput, the appliances
being dismantled only at one workplace. GIZ (2010) reports a volume of about 10 tons of treated e-
waste per year at Valdeme, which corresponds approximately to the number of 500 PCs a year
provided in Rochat and Laissaoui (2008).According to Mr. Baudet, its director, the company has made major efforts for environmental
issues, e.g. the implementation of a waste water treatment or the environmental impact study that
was conducted.

IVSEP
IVSEP (Socit d'Industries Vertes et Services Propres) is a small company in Fes that intends to
start an e-waste dismantling facility, supplying the resulting material fractions to the appropriate
downstream processing. It is important to note that the company is not yet active operationally. A
trip to the terrain of the company revealed that construction works did not start so far (the
designated terrain is an open acre). Some pictures of the field visit can be found in Figure 9 -Figure 12 (page 20).
The company intends to collect e-waste from households via a close cooperation with the informal
sector. The director of the company, Mr. Lhossini, has established contacts to the stakeholders of
the informal sector (scavengers, etc.) in order to structure the collection of e-waste from
households and small companies. The collection strategy comprises the installation of several
take-back points in and around the city of Fes, where some selected and instructed scavengers
can sell their collected appliances at a specified price.
Al Jisr
Even if the main activities of the association Al Jisr consist of the refurbishment of computers and
their reuse in schools, it can be considered an e-waste recycler, too. With its collection and
dismantling project Green Chip, Al Jisr does not only contribute to the solution of the e-waste
issue, but intends to provide a formation to unprivileged adolescents. It is backed up financially by
the Swiss NGO Drosos16and the Moroccan company Managem, which ensures the acceptance of
complete e-waste fractions (see chapter 2.3.1.2).
Thus, Al Jisr is not competing with the further e-waste recyclers. But it has established a well
organised facility in Casablanca where a deep manual dismantling of mainly IT equipment is
carried out.

Ecotechno
Ecotechno is a company which focuses solely on the treatment of e-waste. Ecotechno evolved
from the national school of mineral industry (ENIM17). At ENIM, the two processes were developed
which established the basis for the involvement in the e-waste business. The first process is the
recovery of gold from the PWBs by a wet chemical leaching with an upstream shredding process.
Secondly, the plastic and silica residues from the PWB shredding and further shredded plastic areglued to a sealing material which replaces bitumen plaster. So far, none of the processes was
applied on an industrial scale. Apart from those processes, Ecotechno intends to collect and
dismantle the appliances and supply the material fractions to the appropriate downstream
processing channels.
Apparently, Ecotechno lacks financial funding and thus the company is currently not operative.,
Moreover, efficiency (gold recovery) and compliance with environmental standards (glued plastic
residues) of the developed processes are not clear and need further clarification. According to
Schluep et al. (2009) hydrometallurgical processes as described above are usually not as effective
as a treatment in an integrated metal smelter. Concerning the residual plastic glue, it is not clear if
its exposure to weather leads to an emission to enclosed hazardous substances.

2.3.1.2 Refiner
For certain metal fractions generated during pre-processing national refining options exist.
Especially if metals like Fe, Al, Cu, etc. can be segregated in the dismantling, a national refining
solution is feasible and preferable. Table 3 gives an outline of the main metal smelters, whereas
other existing small and medium scale facilities are not mentioned in the table.
As opposed to this, Morocco does not offer a suitable and established facility to treat complex
fraction containing metals, e.g. PWBs, ICs, processors, connectors and small electronic devices
(mobile phones, mp3-players etc.).

Managem
As described in GIZ (2010), Managem is a subsidiary of the multinational group ONA and its
principal divisions are ore mining and metal refining. Four years ago, Managem became also
active in the field of e-waste, where it focuses on the refining of several metals contained in the
PWBs. Due to their relatively high concentration of precious metals and copper, the PWBs allow
Managem to upgrade its mining ores.For this purpose, a pilot plant with an open electric arc furnace was installed at the plant in
Guemassa, close to Marrakesh. The product of this furnace is a blister consisting of the PWB
metals (see Figure 6). The plants capacity is about 100 t of PWB per month. This plant is not

equipped with an off-gas control system. But according to Managem this isnt required due to the
high processing temperatures (approx. 1600 C) which prevent the generation of dioxins.
In order to supply the future final facility with a
reported capacity of 10000 t of PWB per year
(corresponding to 200000 t of WEEE per year),
the company intends to gather e-waste at a
national and international level. For this reason
Managem is also involved as a primary sponsor of
the Green Chip project in Casablanca, that was
initiated by the association Al Jisr (see chapter
2.3.1.1). The project consists in the collection,
dismantling and recovery of e-waste from
companies and authorities. While Al Jisr manages
the collection and the manual dismantling, all the
resulting material fractions are purchased by
Managem for a price of 1800 MAD23 per ton.
Managem assumes responsibility for the
downstream processing solution of each fraction.
At present, the definite downstream processing
destinations of the different e-waste fractions are
not known. According to Managem several
fractions (e.g. batteries, capacitors, plastic, etc.)
are kept in stock until an appropriate treatment or disposal option is available.
Mac//Z
Mac//Z is located in Skhirat between Casablanca and Rabat. Its main activities are the shredding
and the separation of metal scrap and the fabrication of copper and brass billets and further
products. Those activities include the stripping of Al and Cu cables. For other metals like iron,
aluminum, etc., Mac//Z acts as an intermediary. Some of those metals are exported. Further
information about the company can be found in GIZ (2010).
The company is not involved in the recycling of e-waste, but during a field visit a non-negligible
share of electric and electronic appliances was seen in the input to its automatic shredding
processes. Additionally, several workers were stripping Al and Cu cables. No specific measures
seem to be taken to prevent hazardous contamination which is likely to happen during the
shredding of the e-waste enclosed in the metal scrap.

2.3.1.3 Informal Recycler
In the informal sector several levels of stakeholders have to be distinguished.
At the bottom of the hierarchical pyramid we find the scavengers that work mostly on their own and
collect different materials wherever they can find them (e.g. landfills, households, etc.). As both
GIZ (2010) and Rochat & Laissaoui (2008) report, they do commonly not focus on the collection or
dismantling of e-waste due to a weak market interest/demand. Thus, compared to developing
countries like e.g. India, Ghana or Nigeria, few scavengers are active in the field of e-waste in
Morocco.
While their main activities are directed to other materials, wholesalers and semi-wholesalers do
perform e-waste collection and dismantling to a certain extent. In particular their participation in
tender offers by companies and authorities is reported (Rochat & Laissaoui 2008). As Valdeme
claims, the informal stakeholders usually outcompete the formal participants in those tender offers.
The reports about the recycling practices by the informal stakeholders would confirm this
declaration; their practices mainly consist in the extraction of the valuable parts like metals, while
parts which cannot be commercialized or parts containing hazardous substances are abandoned
or relinquished to the municipal waste collection (cherry-picking). Some reports about open cable
burning exist as well (Rochat & Laissaoui 2008). According to this study, such informal dismantlingin Casablanca was gradually replaced by activities in Sidi Bennour, a small town located 160 km
southwest of Casablanca.
In November 2010 a visit to some stakeholders (scavengers and a small intermediary) of the
informal sector in Fes was organized by Mr. Lhossini (IVSEP, see above). Even if the main volume
of the met scavengers consisted of other materials than e-waste, many scavenged small
appliances that were left behind could be seen (e.g. mobile phones, light bulbs, PWBs, CRT coils,
chargers). Cable burning was detected as well. Some pictures of this field trip are provided below.

2.3.2 International Recycler and Refiner
From an environmental and in most cases also economic perspective, the optimal downstream
processing for fractions with complex or hazardous composition like PWBs, ICs, connectors,
CRTs, mercury lamps, batteries etc. are specialized facilities worldwide. Hereafter, a few options
for those fractions are presented.
GRIAG Glasrecycling AG
GRIAG24was founded in 1997 and is specialized in the treatment of CRT glass. It is located close
to Berlin, Germany. Since 2007 GRIAG is a subsidiary of Stena Metal Holding GmbH25, a
worldwide scrap trading group.
The company accepts whole cathode ray tubes (without casing), crashed cathode ray tubes as
well as separated panel and funnel glass. The price for the treatment of the glass depends on the
condition of the supplied glass. The treatment consists in the removal of other materials from theglass, the separation of the funnel and the panel glass and a purification of the respective glass.
The conditioned glass is supplied to CRT manufacturer in Asia, according to provided information.
MBA Polymers
MBA Polymers26 was founded in 2004 and disposes of three plants located in Austria, China
(Guangzhou) and the United States of America. The company is specialized in the recycling of
plastics, performing the removal of foreign material, the separation of the plastics and the recovery
of ABS, HIPS and PP polymers. In doing so, the facilities are mainly fed by plastics from cars andEEE.
MBA Polymers is one of the few treatment options capable of separating plastics containing
hazardous flame retardants from non-problematic plastic fractions.
Recilec
The company Recilec27, that is located in Sevilla (Spain), offers an integral e-waste management
from collection to dismantling and supply to end-processors. But as the company also accepts
material fractions originating from an upstream dismantling process, it could be an interesting
downstream processing option for e-waste dismantlers in Morocco, also due to its proximity toMorocco. Among others, Recilec would accept the following e-waste fractions:
Cold Cathode Fluorescent Lamps (CCFL). They contain mercury and derive from flat
screens.

22
Cathode ray tubes (CRT); whereas the treatment costs seem to be significantly higher than
those of GRIAG (see Table 7).
2.3.2.1 Integrated Metal Smelters
The recovery rate of precious and base metals contained in fractions PWBs, batteries, connectors,
etc. can be significantly enhanced in integrated smelters abroad compared to a national solution in
copper smelters or other existing plants. There is not a multitude of integrated metal smelters
worldwide. In the table below, some of the smelters are listed.
In general, the smelters charge their services according to a complex payment system, which
bases on the following scheme:
+ % of material value
- Variable charges- Fix charges= Offered price
whereas the variable chargesinclude a percental deduction of the metals, a charge per kg of the
recovered metals, and the fix charges include a treatment charge, weighing & sampling charge
and possibly a shredding charge.
Regarding PWBs, most integrated metal smelter accept all different types, however, low grade
PWBs usually have to be upgraded first (removal of Al and Fe parts, cooling devices, transformer,
etc.). As the aluminum cannot be recovered in the integrated metal smelters, it is recommended toremove Al-parts from the boards (e.g. heatsinks).
In particular the lot size of the shipment is relevant for the acceptance of the shipment. The
minimal lot sizes differ from smelter to smelter and depend primarily on the quality of the material
(the grade of the boards).

2.4 Costs
The purpose of the present chapter is to give a view of the current costs which affect the e-waste
management, in particular the costs considered in the model. The presentation of all gathered data
would be too extensive, hence only the most crucial numbers are reproduced. In appendix 7.3
more detailed numbers can be found.
Most of the provided numbers in this report describe formal activities like transport companies,
downstream processing, labour costs etc. A more thorough compilation of current prices in the
informal sector in Morocco can be found in GIZ (2010). The gathered data in the referenced report
concern sales and purchase prices of e-waste and its fractions between informal stakeholders, e.g.
between scavengers, intermediaries and wholesalers. For the design of the collection concept with
the informal sector, this information gives a good idea about the informal cost structures which
formal e-waste businesses have to compete with.
The exchange rate from Euros to Moroccan Dirhams (MAD) is 1
11,2 MAD (4.11.2010).
2.4.1 Labour Costs
Because of the labour intensity of a manual dismantling facility, the wages paid to the workers
account for an important share of the costs.
The minimum wage in Morocco is 10,64 MAD per hour. If the non-wage labour costs are included,
the monthly minimum wage adds up to approximately 2500 MAD28. Based on experiences of
Empa in other countries, the wage for a common worker in a model facility (dismantling,
refurbishing, etc.) is assumed to be 3000 MAD per month, about 20% higher than the minimum
wage.
Further wages which were used in the model are given below29:
Secretary 3500 MAD/month
Driver 3500 MAD/month
Administration assistant 6000 MAD/month
Manager 15000 MAD/month
2.4.2 Rental Costs
Without knowing for certain where the dismantling facility is located, it is difficult to determine the
rental costs as they can vary according to the location. Several purchase and rental prices can be
found in the appendix. For the model, a price of 9,38 MAD per m2and month has been calculated
28Information provided via mail by Al Jisr
29Those wages rely on indications from Valdeme

based on a rental price for a storage depot in an industrial zone Tit Mellil/Casablanca30. The
reason for the selection of this price was its average value compared to the other data which were
gathered.
2.4.3 Commodity Prices (incl. PWB and battery prices)
Via the commercialization of the fractions directed to the downstream processing, in particular of
PWBs and metals, the commodity prices significantly affect the revenue of e-waste businesses.
These prices are set on an international level, so the business is strongly dependent on those
global markets and thus is very sensitive to this factor. A strong fluctuation of the commodity prices
could be observed during recent years, what demonstrates the sensitive reaction on this factor of a
business like the one delineated in this study. Since the striking decline of the commodity prices in
2008, most of them have reached similar or even higher levels than before the global economic
crisis.
The commodity prices which were applied in the model are the average prices of 201031(reference
scenario, see chapter 3.2.1). In the table below the metal prices which are relevant for e-waste are
presented.
Table 5. Average commodity prices for 2010.
Au Ag Pd Cu Al Fe32

2010 1'199.15 18.80 493.18 7'300.00 2'150.00 480.00
Obviously, the sale of the base metals (Cu, Al, Fe) does not bring in 100% of the prices presented
in the table, but solely a certain percentage of them. Based on indications from Mac//Z and a Swiss
recycler, the following percental price reductions were used in the model:
Copper LME33-price minus 20%
Aluminum LME-price minus 20%
Scrap iron LME-price34minus 50%
A highly relevant fraction for the revenue are the PWBs. Among others, their commodity price is
determined by the prices of Au, Ag, Pd and Cu. The price calculation used in this study is based on

the business model used by Umicore Precious Metals35, Belgium. Hereafter, the PWB prices for
the respective minimum lot sizes based on the average metal prices of 2010 36are given:
PWB high grade (Au content of 200 - 300 ppm) +/- 9000 /t (lot size of 5 tons)
PWB medium grade (Au content of 100-200 ppm) +/- 5500 /t (lot size of 7 tons)
PWB low grade (Au content of 50-100 ppm) +/- 2500 /t (lot size of 10 tons)Those prices for PWB include all charges by Umicore, but do not comprise the transportation
costs.
The prices for batterieswhich Umicore Battery Recycling offers depend on the current commodity
prices for cobalt (in case of Li-ion batteries) and nickel (NiMH batteries) 37. According to Umicore,
the average share of those two types of laptop batteries is approximately 87,5% Li-Ion and 12,5%
NiMH batteries.
2.4.4 Transportation Costs
Many different kinds of transportation are involved in e-waste management, in particular if it is
interlinked to the global markets. First, the appliances must be collected to a facility, then the
respective fractions are distributed to national and international downstream processing. In this
particular case, transportation by lorry, by train and by ship was considered.
The table below gives an idea about the most important costs which were taken into account in the
model.

With regard to the transport types, for the transport by land significantly higher transport costs must
be expected than for the transport by sea. Furthermore it was found in the model results that the
share of the transport costs per ton of the total downstream processing costs per ton is generallyrather small.
2.4.5 End-processing costs
Depending on the generated volume of the respective fractions, the end-processing can result in a
non-negligible expenditure. In the subsequent table, some of the relevant end-processing data are
compiled.

3 Model Development
3.1 Outline of Relevant Elements
This chapter provides an outline of the stages that should be covered by a sound e-waste
management system. Furthermore, in this chapter it is defined which stages comprise whichspecific processes. For several processes, a short description/definition can also be found in the
glossary at the end of this report.

3.1.1 Administration
Administration comprises multiple activities in order to organize the employees and the existing
resources efficiently so as to achieve the objectives of a sound e-waste recycling. Instead of
describing all those activities separately, the most important are listed below:

3.1.2 Public Relations
The awareness of the social and environmental implications and opportunities of e-waste among
consumer has a strong impact on the success of e-waste collection, in particular in households.
This awareness is generally quite low in Morocco and poses a major obstacle especially for the
collection of appliances from households.One could argue that a strategy to overcome this challenge is to significantly raise the budget for
public relations. As experiences in other countries demonstrate, an adequate public relations (PR)
campaign aiming at a stimulation of the awareness among consumer can account for a significant
percentage of the overall budget of e-waste businesses38. But contrariwise the present project
doesnt dispose of the dimension and potential to foster the awareness of a whole society. Hence,
it is certainly necessary to promote the business and sensitize the consumer to the solution
offered. But theres no point in spending too much resources given the uncertainties of the actual
effect on the return of WEEE.
The most crucial points which a PR campaign for WEEE collection should focus on are: dissemination of appropriate information among consumers,
coherence and simplicity of information,
easy access to information for consumers and
credibility and transparency of the e-waste businesses.
The expenditures related to a PR campaign can vary a lot according to size, design, duration, etc.
of it. Hence, its costs are included in the model under further costs(see chapter 3.2.1).
The last point listed above indicates that instead of wasting too much funds for PR, the businesses
should rather focus his efforts on a collection design which facilitates easy access, good service
and transparent and plain information to consumers. In other words: the collection success of a
business is strongly dependent on a good coordination of the PR strategy and the collection setup
(chapter 3.1.4).
3.1.3 Financing schemes
If the intrinsic value of the obsolete appliances is not covering the complete expenditures for theWEEE management, additional sources for revenues have to be accessed. This can happen by
different financial schemes, which are briefly described below.
Fee on disposal At the collection site, a fee is paid by the final user at the moment of
return of his obsolete appliance.
Advanced recycling At the moment of purchase, the consumer pays a fee on his new

The obsolete PCs arisen in the public and private sector are especially attractive for e-waste
collection, because the stock of PCs in a company is usually substituted as a whole. This reduces
significantly the collection expenditures.

The numbers provided by the two studies indicate practically the same range of e-waste volumes
for 2008. Only the estimated volumes of mobile phones differ by a factor of three.
3.1.4.2 Potential Collect ion Channels
Depending on the accessibility and density of the appliances in the different sectors, various
channels have to be established in order to collect them efficiently. In particular, households on the
one hand and the private and public sector on the other hand must be distinguished.
8/12/2019 E Waste Morroco Blaser_2011 HP-Empa
36/86
Current Situation and Economic Feasibility of e-Waste Recycling in Morocco
32
Due to the less challenging accessibility of the PCs in the public and private sector(companies
and authorities) and the fact that IT is the business segment of HP, it is recommended that in a first
phase a collection channel focuses on those PCs (B2B-channel39). In the beginning, this should
ensure a basic input into the recycling facility and allow for a gradual build-up of the further
channels to cover the obsolete appliances generated in the households. Potential collection
channels for this purpose are: Direct collection of the appliances at the companies, respectively authorities by:
o participating in their calls for tenders. As long as the companies/authorities do not
impose some minimum conditions for treatment, a bidder of the formal sector runs a
high risk of losing the calls for tenders given its higher treatments costs compared to
a bidder of the informal sector (see also Valdeme, chapter 2.3.1.1).
o negotiating directly with the companies/authorities in order to get the appliances
circumventing a call for tenders. Depending on the appliance and the
companies/authorities, a price can be fixed. As a return service, the recycler can
offer an environmentally sound treatment of the appliances and possibly even a
certificate for this service. An existing example for this kind of collection is the Green
Chip project of Al Jisr40, see chapter 2.3.1.1.
Indirect collection of the appliances via the approximate 20 retailers supplying the major
account segment41. This alternative could become very effective to collect the appliances
of major consumers. The basis for the success of this alternative is a contract between the
retailers and the major consumers which assign an exclusive take-back right for the old
appliances to the retailers. With its strong PC market share of 35% in Morocco (Rochat &
Laissaoui 2008), HP can possibly bring the retailers to conclude such kind of contracts withtheir consumers.
At the same time the presented numbers indicate that in the medium and long term a recycling
facility treating not exclusively IT equipment cannot be run depending primarily on a simple B2B
collection model. From the distribution of the appliances between households, the private and the
public sector, it can be deduced that the main collection channels must be adjusted to get access
to the appliances in the households, whose collection requires a much higher effort than in the
other sectors. The following collection channels exist to collect those appliances (C2B):
Return of the obsolete products to the selling points by consumers (supermarkets,
specialized shops, etc.).
Integration of and cooperation with the informal sector (scavengers) by using its experience
and existing collection channels and providing formal labour opportunities.
39In a so-called Business-to-Business (B2B) model the appliances are collected directly in the companies.
40http://www.aljisr.ma/article.php3?id_article=187
41Major account segment: primarily made up of government agencies and public bodies (Ministries and Offices), as well
as major private actors (banks, insurance companies, industrial companies, multinationals) (Rochat & Laissaoui 2008)

Municipal or private collection points for WEEE (possibly together with other waste
streams).
Periodic mobile collection with direct pick-up from the households (door-to-door collection).
Reverse Logistics42
Reverse logistics refers to a collection system that capitalizes the existing distribution channels of
new products in order to gather obsolete products along those channels, but in the opposite
direction. The idea of such a collection design is reducing the transportation effort by reducing the
number of pick-up points and therefore capitalizing the transportation which is performed anyway.
The functioning of an exemplary design of reverse logistics is given in Figure 14.
Figure 14. Reverse logistics - capitalization of d istribution channels.
In this figure, the red lines represent the stages where existing distribution channels are capitalized
in the opposite direction. In doing so, the pick-up points are reduced by accumulating the obsolete
appliances along those channels towards the wholesaler, respectively manufacturer/importer.

3.1.5 Transportation
The transportation of e-waste includes various stages beginning with collection of the appliances
and ending with the transportation within and out of the recycling and refining chain (moving
processed parts or material between different facilities, disposal, export, etc.). Usually, the
transportation represents a relevant cost share
43
, whose actual amount strongly depends onfactors like the geographic coverage of collection, the collection and logistics design and the legal
guidelines (classification as hazardous waste). For legal requirements or requirements by HP with
regard to transportation, see chapters 2.1.2 and 2.2.4.
3.1.5.1 National
National transportation of e-waste respectively its components and materials will mainly be
performed by truck, but as Morocco disposes of one of the most modern railway systems,
transportation by train should be considered, too. See also chapter 3.1.4.2 (reverse logistics).
3.1.5.2 International (Export)
Within the realms of possibility, an objective of the project is to capitalize national recycling and
refining options. In case of the processing of base metals or other material in metal smelters or
cement production, this is definitively possible and often economically and environmentally
advantageous.
The export of components or materials to state-of-the-art refining plants generally involvestransportation by ship (see chapter 0) to Europe, North America or Asia, which entails more
complicated transportation procedures like shipment completion and customs clearance, that raise
the transportation costs. The main international ports Casablanca, Mohammdia and Jorf Lasfar
are located around Casablanca (approx. 72% of the maritime trade44), but since 2006/07 an
important port with a container terminal is in operation in Tangier.
It has to be considered that Morocco is a signatory state of the Basel Convention (see chapter
2.1.4). For this reason, the transboundary movement of hazardous waste requires a notification.
3.1.6 Sorting, Handling and Storage
This chapter refers to the general manipulation of the appliances in any treatment facility. For
reasons of control, efficiency and security, it is essential to take account of :
an organized and logistically reasonable handling,

a careful documentation of the appliance and material stocks and flows,
the protection of the workers and
a safe and proper handling and storage of the appliances and their respective components
(prevent release of hazardous substances).
Upon arrival at the dismantling facility, as a first step the appliances pass through a sorting step
(not definitive, to be adapted):
Figure 15. Exemplary sor ting tree for the main appliances cons idered in the study.
Afterwards, if no immediate transfer to the treatment is possible, the classified appliances are
stored properly again.
These stages are apt for a cooperation with scavengers (informal sector).
3.1.7 Manual Dismantling
The main goal of the manual dismantling (which is part of the pre-processing) is to prepare the
obsolete appliances for the downstream processing by way of breaking them down into theirrespective fractions. The suitable dismantling depth is highly dependent on the further treatment
those fractions pass through.
The objectives of the dismantling are the following:
separation and sorting of different materials and components, preparing them for further
treatment,
removal of contaminated components (depollution),
concentration of particularly valuable components by separating them (optimize material
revenue), generation of employment and inclusion of the informal sector.

Particularly in developing countries, the design of the manual dismantling is essential, given that
labour costs are rather low compared to industrialized countries. The low wages allow for a
relatively deep manual dismantling which results in a high recovery rate of the treated material
maximizing revenue. As mentioned above, this stage is apt for a cooperation with scavengers
(informal sector).
3.1.8 End-processing
After the dismantling stage, the separated fractions dont pass through any further major treatment
in the dismantling facility. An exception is an eventual shredding step of certain fractions (plastics,
metals, etc.) in order to comply with acceptance requirements of their purchaser and facilitate their
transportation.
The end-processing is realized in different industries which handle the materials and components
separated during the dismantling process. Some of the fractions which have to be supplied to end-processors are delineated below. Table 11 in chapter 3.2.1.1 gives an outline of the selected
destinations for the materials and components in the model calculations.
Printed Wiring Boards
PWBs consist of a complex mix of metals and organic compounds. A typical composition of a PWB
from a PC is 7% Fe, 5% Al, 20% Cu, 1.5% Pb, 1% Ni, 3% Sn and 25% organic compounds.
Additionally, 250 ppm45Au, 1000 ppm Ag and 100 ppm Pd and traces of As, Sb, Ba, Br and Bi can
be found (Hageluken 2006). The PWB composition is on the one hand an opportunity due to thehigh value of the inclosed precious metals, but on the other hand it poses a risk due to the
occurrence of hazardous substances. Given this material complexity, a major challenge of the
PWB treatment is to achieve an efficient recovery of the various metals without releasing
hazardous substances.
On the global markets, the end-processing of PWBs is usually performed in state-of-the-art
refineries which combine hydro- and pyrometallurgical operations (see Table 4). In those state-of-
the-art facilities a high recovery rate for a wide range of metals is possible.
Nevertheless, methods like wet chemical leaching of metals are still carried out in many countries,
predominantly in the informal sector. Those processes do not only have adverse environmentalimpacts and pose a threat to human health, but are also inefficient in terms of metal recovery. A
study conducted in India concluded that the metal loss in those processes carried out in the
informal sector is significant compared to the refining in an integrated metal smelter (Keller 2006).
Batteries
Many types of batteries are found in e-waste and their composition is diverse. Some types of them
contain hazardous substances which must be disposed of appropriately.

In the appliance scope considered in this study, the main volume of obsolete batteries is found in
laptops. Thereof, roughly 10 15% are NiMH batteries and 85 90% are Li-Ion batteries (UBR
2010). Furthermore, small buffer batteries with different shapes (e.g. button cells) can be found on
PWBs (Gabriel 2000). Depending on the existing alternatives, it may be reasonable not to remove
those small batteries from the PWBs and supply them to an integrated metal smelter which treats
them according to the required standards (see chapter 2.3.2.1).Schluep et al. (2009) recommends to send the batteries of electrical and electronic equipment to
dedicated plants for the recovery of cobalt, nickel and copper. In Europe, more than 40 specialized
battery recycling companies exist (EBPA 2010).
According to Valdeme, the batteries resulting from their e-waste dismantling are supplied to a
company in France. No further information on the plant was provided.
In the model, the laptop batteries are assumed to be treated at Umicore Battery Recycling in
Hoboken, Belgium. Among other materials, Umicore is specialized in the recovery of some metals
in NiMH and Li-Ion batteries.
Plastics
Various types of plastic exist, of which ABS, polystyrene (PS) and polypropylene (PP) are usually
used in computer manufacturing. In addition, many other types are used depending on their
characteristics, as well as plastic compounds.
Generally, it is difficult to avoid a deterioration of quality in plastics recycling (downcycling).
However, recent progress in process technology allows the recovery of some kinds of plastics (see
chapter 0). A crucial step to reduce this deterioration is the appropriate separation of the variousplastic types, which requires either state-of-the-art technology or an extensive know-how of the
plastics.
Concerning the plastics used in electronic equipment, a major problem are the halogenated flame
retardants (FR) found in various plastics and the polyvinyl chloride (PVC) in wire insulation. If those
kinds of plastic are burnt, toxic dioxins and furans is generated. Therefore, this fraction requires a
special treatment.
Cathode Ray Tubes (CRTs)CRT monitors from computers and TVs account for a large share of the e-waste volume in the EU
categories 3 & 4. They represent an environmental hazard due to their fluorescent phosphor layers
which contain several toxic metals (e.g. cadmium) and due to the high lead oxide concentration in
the cone glass of the tube. Among the potential controlled disposal options, the following are
mentioned in Schluep et al. (2009):
The secondary production of new CRT glass (screen to screen; (lead containing) cone to
cone glass; to a lesser extent for mixed glass to cone glass),
Smelter options (in particular mixed glass to Cu/Pb smelters),

38
Other industry (e.g. pane glass to ceramic industry as feldspar replacement; funnel glass to
cement industry as coarse gravel replacement; mixed glass to cement industry as fine
gravel bricks or to salt mine as filler).
3.1.9 Controlled Incineration and Disposal
While the bulk of e-waste fractions can be recycled, certain fractions are not suitable for recycling
and therefore have to be disposed of. The most common solution for those fractions is the
controlled incineration or/and the disposal in hazardous waste landfills. Non-hazardous waste
fractions that are not recycled, may be disposed of in a controlled municipal waste landfill.
Apart from municipal waste landfills, no fully developed solution for the incineration or the disposal
of hazardous waste exists in Morocco. This forces a responsible e-waste business either to stock
or to export those e-waste fractions to adequate plants abroad. Nonetheless, progresses of
emerging national initiatives should be kept track of, e.g. the CNEDS46hazardous waste plant.
3.1.10 Monitoring
Even though it is readily ignored, the monitoring of the recycling and the control of accounting
represent the basis for the credibility of a recycling business. Its main functions are:
Ensure of the compliance with (HP) requirements
Ensure of the legal compliance
Ensure fair/equal market conditions (level playing field) Control the mass flow within and between the businesses (collected volume, treated
volume, etc.)
Collect and manage relevant data
Establish the basis for and give credibility to the certification of the facilities
3.1.11 Refurbishment
Mainly three reasons exists to refurbish obsolete appliances. Firstly, its an business decision dueto the revenue which possibly can be generated. Furthermore can be an environmental advantage
to extend the lifetime of the devices and thereby reducing the volumes of generated e-waste. And
last but not least the refurbishment provides also a social benefit by generating jobs and procuring
low-budget or even free appliances to the costumers.
According to StEP47, refurbishment comprises any action necessary to restore a unit up to a
defined condition in function and form that may be inferior to a new unit. The output product meets

the original functionality specifications. To refurbish a product requires disassembling the unit only
to the extent that is required to ensure the testing and reprocessing of all components not meeting
these specifications. The units composition and design is not changed significantly. The term
reconditionis understood synonymously for refurbish (StEP 2009).
Moreover, it should be considered that refurbishment implies a supplementary sorting of all
collected devices and a supplementary testing of the devices selected for refurbishment. Thus, tooperate refurbishment requires a not negligible additional labour force.

3.2 Model Description
Based on the gathered information during the present study and during the investigations of the
report by GIZ (2010), a Microsoft Excel based model of an e-waste business was developed in
order
1. to estimate the rough cash flow of a potential e-waste business, and
2. to deepen the knowledge of the sensitivities of the business in order to identify the key
processes and parameters.
The purpose of the model is to consider all relevant financial flows which occur during the
operation of a local e-waste business. The model core consists of a dismantling operation, where
the appliances are disassembled manually. It is designed to include several appliances of the EU-
WEEE directive categories 3 and 4: PCs (LCD & CRT monitor), laptops, printers, mobile phones,
TV sets (LCD & CRT monitor), audio devices and video devices. Around this dismantlingoperation, the following components associated to e-waste business are taken into account:
Transports
Transports during collection, from dismantling to downstream processing

Refurbishment of desktop PCs and laptops, comprising a previous sorting and testing of the
collected appliances (optional)
Labour and rental costs, further costs as well as the sale of the refurbished appliances were
taken into account.
The cost calculation for the dismantling operation itself comprises the labour and rental costs plus
further costs as a percentage of the former.

3.2.1.1 Downst ream processing
Through the dismantling of the appliances various material fractions are generated. For each of
those fractions, several downstream processors are conceivable. Table 11 gives an overview of
the different downstream processing alternatives which were arranged. Hereafter, the purpose of
each alternative is described:Alternative 1 The downstream processing is carried out in Morocco, irrespective of the costs or
the environmental performance.
Alternative 2 The downstream processing generates as much revenue as possible and causes
as little costs as possible, irrespective of the treatment location or the environmental
performance.
Alternative 3 Main purpose is to carry out the downstream processing in an environmental sound
manner as far as possible. Additionally, the downstream processing is economically
optimized, considering national processors as well as international processors.
Table 11. Downstream processing scenarios for each fraction (alternative 3 was chosen as referencesceanario).

The selection of the different downstream processors is highly relevant for the environmental and
financial performance of the e-waste business. HP requires strict environmental and EHS
standards (see chapter 2.2), so in a potential pilot business only downstream processors that
comply with those standards can be considered. Thus, of the 3 alternatives presented in Table 11
alternative 3 was selected as standard downstream processing for the reference scenario and all
the further parameter sensitivity analysis.
3.2.2 Refurbishment Module
Apart from the main division of the business the recycling of e-waste , an additional potential
division is the refurbishment of suitable devices which are collected in order to sell them. The
explicit motivation for this supplementary activity is to establish an additional revenue source.

However, if the refurbishment of collected appliances does not contribute to a better financial
performance of the business, there is little reason to include this business activity.
In the model, the whole refurbishment comprises several stages. Firstly, all the collected
appliances are sorted according to their suitability for being refurbished. Then, those devices are
tested for their functionality and finally the refurbishment itself is carried out.
The purpose of this module is to get an idea of the uncertainties related to the question: What
would be the economic effect of an inclusion of the refurbishment under different circumstances?
3.2.2.1 Basic Assumptions
Due to a considerable lack of hard data concerning the refurbishment of e-waste, several rough
assumptions had to be made. Some of those assumptions rely on experiences made in South
Africa51, but nevertheless the results of the refurbishment modeling should be interpreted carefully.
