President's comment
Patron members of the IWMSA
It is not so long ago that we returned
from the holiday season at the beginning
of the year, then we were plunged into
the Easter holidays, and with more public
holidays at the end of April it would appear
that there is little time for work! However,
despite this, there seems to be a lot of
work around and a number of people I have
spoken to appear to be very busy. At the
IWMSA, we have been very busy right from
the beginning of the year with a number of
training courses and, of course, our flagship
event WasteCon 2012, which is to be held
later this year in East London.
Nominations for branch committees and vice-
president have been received and we will soon
call for elections, so please take the time to
vote and make sure we get an energetic new
team in place for the next two years!
Talking of elections, it is amazing how time
has passed so quickly and to think that my
term of office will be over at the end of June.
The last four years on the council have been
exciting, fruitful and very busy with a number
of projects or programmes that were initiated
and even completed! Foremost, we set
ourselves a number of strategic objectives,
which included the following:
• The development of effective communica-
tions with our members and the public,
which included an electronic newsletter
(WasteVine), an upgraded website, regular
announcements via SMS and e-mail,
and regular press releases on topical
issues. Judging from the number of media
requests and the resulting exposure, it
would be safe to say that the IWMSA is
now recognised as the authority on waste
management in South Africa.
• The development and provision of training
courses, including accredited courses.
The IWMSA is also being contracted by
some large organisations, particularly
municipalities, to provide training for
their employees.
• The accreditation or registration of our
organisation members who are service
providers. This process is well advanced
and a number of stakeholder workshops
will be held during the course of this year
to engage with the relevant stakeholders
for their input.
• Government liaison – various initiatives
are being pursued by IWMSA members
in interacting and liaising with govern-
ment departments at different levels.
These include invitations to workshops
and forums.
• To involve ourselves in social responsibility
opportunities with school programmes,
supporting communities and providing
assistance to those with existing
programmes, resulting in tangible
grassroots impact where projects get
benchmarked and used by municipalities
as well as small and micro enterprises.
• Transformation – the IWMSA has
been reviewing its policies and
procedures in terms of procurement
and, of course, our demographic
profile. I am happy to report that the
demographic profile of the IWMSA
membership has changed
significantly and membership
is now slightly below 1 000,
the highest it has been in the
history of the IWMSA.
I am indeed proud of the above
achievements and can only praise
the team that I have had the
pleasure to work with, namely all
the Council Members (who ran their
portfolios with great dedication and energy),
and the ladies in head office (Gail, Ann and
Sanki). To all of you, I say thank you.
Unfortunately, we have also had our
disappointments over the past two to four
years and these mainly revolved around
health care risk waste (medical waste)! The
one area which we have not been able to
resolve is the issue of the management of
the Health Care Waste Forum (HCWF) as
previously reported. I trust that the incoming
council will give this their full attention as
the next Health Care Waste Summit is due
early next year.
On a closing note, I wish to report that the
council, in the last council meeting in March,
took the decision to reinstate Wasteman
Holdings (Pty) Ltd as a Patron Member.
This decision was taken after a lengthy
process which included an independent
audit of Wasteman’s processes and policies
which were put in place subsequent to their
suspension from the IWMSA. A number of
the other Patron Members have welcomed
this decision.
Finally, as this is my last opportunity
to say goodbye to the readers of
RéSource, I would like to thank
all members who supported me
during my term of office
(including those with
constructive criticism),
members of the
National Council
and the head office
staff for making my
job easier.
Regards,
Stan Jewaskiewitz
President, IWMSA
Farewell and thank you
RéSource May 2012 – 3
RéSource May 2012 – 5
With Christmas 2011 a not-so-
distant memory, it’s scary to
know that Easter has already
come and gone. And as we usher in the
winter months, we also bid farewell to the
current president of the IWMSA (Institute
of Waste Management of Southern
Africa), Stan Jewaskiewitz, founder and
director of Envitech Solutions, whose
term of office comes to an end in June.
Apart from secretly fantasising about
becoming a world-famous chef, Stan
spent the past two years dedicating his
free time to, and sharing
his expertise with, the
waste industry.
I took over as editor of
RéSource when Stan came
into office and hence
was not given sufficient
time to conduct a proper
‘background check’ on him
– as we editors like to do
with every new president who comes on
board. But working with Stan on claiming
back the magazine’s institute status by
fairly representing all waste management
sectors under the IWMSA umbrella, has
been an absolute pleasure.
Although he doesn’t always stick to his
promises, such as cooking me the best-
tasting game meat I’ve ever eaten, his
openness and helpfulness will be missed
by the RéSource
team. Stan will
officially hand over
the presidency
at the opening
of the IWMSA’s
biennial conference
and exhibition,
WasteCon, which
will be held in East
London from 8 to
12 October.
Farewells aside,
in addition to
the front cover
story, this issue
of RéSource also
kicks off with the
first the latest
offering from the
Mercedes-Benz commerical vehicle
division – TruckStore (see pages 6 and 7
for more information).
This month’s line-up also includes
another panel discussion, this time
focusing on recycling in relation to both
consumers and industry. And Pikitup is
at it again, pushing towards sustainable
transformation in the city of gold. See
page 10 for the full story.
Also on the agenda is a very interesting
paper on the use of earthworms in waste
management. With increased emphasis
being placed on
waste reduction
to landfill, this
paper outlines a
pilot project that
was conducted
at an abattoir
in Gauteng,
highlighting
the challenges
experienced in relation to the National
Environmental Management Bill
(page 13).
Rounding up, the Responsible
Packaging Management Association
of Southern Africa celebrates its
10th anniversary this year and, as an
association addressing environmental
needs, RéSource celebrates their
achievement and wishes them 10 more
years of success and
industry support
(page 50).
If you haven’t already
booked your spot at
WasteCon, stands and
delegate seats are
selling out fast – so
book now to avoid
disappointment. For more
information on the event,
refer to page 68.
Happy reading!

USED COMMERCIAL VEHICLE SPECIALISTS
TruckStore is a fi rst for Mercedes-Benz South Africa and will soon become one of the largest used-vehicle dealers for commercial vehicles.
Cover story
Introducing TruckStore from Mercedes-Benz
TruckStore, the used commercial
vehicle specialist from Mercedes-
Benz South Africa, is ready to start
construction of a brand new facility for
the Southern African market. Preparing
for the necessary earth works, and then
commencement of construction, the
TruckStore team is kicking-off with an
official ground-breaking ceremony on site at
Highway Business Park, Centurion.
The roll-outTruckStore is one of the largest used
commercial dealer networks in Europe and
will now officially be launched to the Southern
African marked by the middle of 2012. In
the Daimler Group, TruckStore is responsible
for the professional, international used-truck
business, involving trucks of all brands and
ages, and with all body types. TruckStore in
Europe is growing constantly and already has
30 locations in 14 European countries and
has a rolling stock of around 4 000 vehicles,
selling more than 20 000 vehicles annually.
TruckStore is a first for Mercedes-Benz
South Africa and will soon become one of the
largest used-vehicle dealers for commercial
vehicles – vans, trucks, buses and trailers.
TruckStore sells vehicles of all brands,
body configurations and ages. Conveniently
situated off the N1, on 30 000 m2 of prime
real estate, the facility will have ample parking
for large vehicles and is well-situated in
Gauteng – between the two major airports
(OR Tambo and Lanseria) for the convenience
of its clients.
Construction preparationFollowing numerous geometric tests, it was
identified that the ground works require a
significant amount of preparation due to
the dolomite in the area. A fair amount of
excavation will take place – 15 000 m³, which
equates to 1 500 truckloads of earth – after
which the area will be compacted and the Oliver Marte, project manager: TruckStore, and Roy van der Walt, TruckStore manager

earth returned to the site. Following the
earthworks, construction will commence. The
builders will be laying around 1.25 million
paving blocks to complete the professional
display area.
Consideration has been taken into the
design of the building, which will be both
functional and environmentally friendly.
Certain eco-friendly measures will be put
in place, such as retaining the rainwater
for irrigation and installing solar geysers to
minimise electricity costs.
Architect Boorgertmann & Partners is also
the contract manager of the building project,
while building contractor JC van der Linde and
Venter is the main contractor.
A proven conceptTruckStore is a Daimler initiative that began
operations in 2002. This proven model
concept has been adapted to suit the local
market. TruckStore accepts commercial
vehicles of any vehicle type or brand in part
exchange; the condition of every vehicle is
thoroughly checked and assessed on the
basis of uniform standards.
Vehicles are then sub-divided into the
product categories: gold, silver and bronze.
This ensures that every vehicle delivers what
is promised.
TruckStore will also have a dedicated
reconditioning centre based at Zandfontein,
which will also serve as the national return
centre for the finance house: Mercedes-Benz
Financial Services. Dedicated technicians
and service staff will bring these used
commercial vehicles up to set standards,
at the Zandfontein facility, ensuring that
these vehicles meet TruckStore benchmark
standards. As part of the Mercedes-Benz
South Africa commercial vehicle value
chain, TruckStore customers will benefit
from a range of services specifically for
used commercial vehicles, such as finance,
insurance and warranties.
Online product offeringThis TruckStore initiative will ensure
significant growth in the used commercial
vehicle segments and the close collaboration
with the Mercedes-Benz South Africa dealer
network will be strengthened. For product
information, visit www.truckstore.co.za. The
website recently went live with full details for
customers to familiarise themselves with the
new and exciting TruckStore concept. Once

Listed South African company
Interwaste adopted the Tops & Tags
initiative in August last year, which
gives back to the community and assists in
the preservation of the environment. The
tops that come off bottles and tags that
are used to seal the plastic coverings of
loaves of bread are the new way to help the
less fortunate.
For every 10 000 bread tags or plastic
bottle tops collected by Interwaste, one
registered charity will receive a wheel chair.
Corporate and individual participants are
invited to join Interwaste in this initiative by
giving back to an underprivileged project of
their choice.
They will not only be contributing to a
sustainable environment, but will also
receive a Certification of Participation and
will be acknowledged on the website.
When the company collected its first
10 000 tops and tags in aid of this
initiative, a wheel chair was donated to
Hospice Soweto.
“Our request is simple,” says Jason
McNeil of Interwaste, “when you buy a loaf
of bread or a bottled beverage, please keep
the tops and tags and give it to us, and we
will not only recycle these items but also
give back to a needy organisation.”
There are various drop-off/pick-up
points where these recyclable materials can
be placed:
• Richards Bay: 126 Alumina Allee, Alton
• Durban: 42 Brooklyn Road, Jacobs
• Boksburg (Gauteng): Cnr
Commis sioner and Atlas Road,
41 Davids Street, Boksburg
• Germinston: 5 Brammer Street,
Industries Site, Germiston East
• Nelspruit: 10 Bosch Street, Nelspruit
• Cape Town: 6 Montreal Drive, Airport
Industria, Cape Town.
The eeZeeBin systemIn addition to its Corporate Social Investment
projects, Interwaste also introduced a new
waste collection system last year called
the eeZeeBin system, which allows for the
collection of recyclable materials including
paper, cardboard, plastic, glass and cans
which can be deposited into a single bin
without any further sorting and separation.
“Dedicated collection vehicles are
employed to regularly collect and compact
waste before transporting it to the Materials
Recovery Facilities Company for final sorting
and reprocessing. Six cubic metre-bins are
available for use at high volume generation
points with 240 ℓ wheelie bins for smaller
loads,” says McNeil.
EeZeeBins are used by corporates,
schools, universities, event companies
and others that are interested in keeping
the environment safe, and provide
branding opportunities.
McNeil says everyone should realise when
glass or aluminum, for example, is not
recycled, it costs the earth because glass
takes up to 4 000 years to decompose in a
landfill. This can be easily avoided through
the use of the eeZeeBin.

JOBURG’S SUSTAINABLE TRANSFORMATION
From creating jobs and encouraging active citizenry to reduce waste to the city’s strained landfi ll sites and converting waste to energy, Pikitup has a signifi cant role to play in helping Johannesburg meet its 2040 Growth and Development Strategy goals and, ultimately, its aim of becoming a world-class African city.
Solid waste
Scaling up waste management initiatives
landfill sites and reduce greenhouse gases,”
he adds.
Waste-to-energy technology In September 2011, Pikitup implemented
gas-to-energy conversion at its landfill site at
Robinson Deep. By extracting the methane
gas and flaring it, the harmful effects of
greenhouse gases are eliminated. The next
step is to convert the gas to energy, which
Pikitup hopes to kick off this year. This
requires being registered as an Independent
Pikitup acting MD Lawrence Boya
says that as an agent of the
city responsible for solid waste
management, Pikitup has a meaningful
contribution to make in transforming
Johannesburg into a city that is sustainable,
liveable, globally competitive, inclusive and
resilient. Boya says methane gas, a by-
product of landfill sites, contributes towards
greenhouse gases and global warming. “By
instituting alternative waste management
practices, Pikitup can divert waste from
Power Producer with the National
Department of Energy, tariff approvals and
identifying a purchaser for the energy.
In addition, Pikitup is investigating various
waste-to-energy technologies such as
absorbing waste into an incineration process
and converting the by-product of this process
into steam, electricity or heat. “Every year,
1 million tonnes of waste goes to landfill –
our target is to convert at least half of this
into energy,” says Boya. When this gets off
the ground, Johannesburg will be one of the
first cities in the developing world to institute
this type of technology, apart from China.
“This will hopefully expand to all cities in
South Africa and ultimately contribute to job
creation and economic growth,” says Boya.
Contributing towards recyclingSeparation at source will also play an
important role in reducing waste to

Solid waste
intends to formalise separation at source
for all Johannesburg households in July
2012; in this respect, citizens will have to
play an active role in reducing, recycling
and reusing.
In addition to separating their waste,
households will be encouraged to start
compost heaps that can be used to nurture
gardens or vegetable patches, thereby
further reducing the amount of green waste
going to landfill. Boya says Johannesburg
needs to transform its current model of
‘collect, transport and dispose’, to a model
of ‘reduce, recycle, reuse and remediate’.
“This will put us in line with international
best practice and the National Environmental
Waste Act of 2008. Essentially, this year
sees the scaling up of the plans we put in
place in 2011. The landfill gas-to-energy
project will be instituted at all five landfill
sites, separation at source will become a
city-wide endeavour and a five-year plan to
build a plant for the conversion of waste to
energy will get under way,” he says.
Holistic approachTo ensure that the city’s waste management
by-laws are adhered to, Pikitup has enlisted
the support of the Johannesburg Metro
Police Department, which has provided
34 dedicated police officers to enforce
the by-laws. This is because the issues
especially relate to illegal dumping and
littering. “We will take stronger action if
these pleas are continually ignored; however,
we will continue to raise awareness and
educate the public on the importance of
disposing waste efficiently and as directed
by Pikitup,” says Boya.
Pikitup also views job creation initiatives by
communities in a positive light. “In addition
to waste pickers who collect plastic and
other items for recycling, we are aware of
young people in the townships who enter into
agreements with households to take their
bins to a central point for waste collection
and then clean them before returning the
bins to their owners. We believe this type
of initiative can be organised and expanded
to provide additional opportunities for
unemployed individuals,” says Boya.
Looking at the overall cleanliness issues
faced by the city, Boya says rodents have
become a significant health hazard. “By
promoting anti-littering campaigns and
providing the proper infrastructure to support
this, Pikitup can begin to address this
problem and at the same time dovetail these
efforts to complement the city’s health
objectives,” he says. He is confident that
Johannesburg is on its way to becoming a
low-carbon economy.
will therefore contribute towards a more
sustainable city.
Boya says businesses, manufacturers
and households in the city need to adopt
greener waste disposal practices. “Waste
needs to be separated at source and items
that don’t need to go to landfill need to
be recycled,” he says. Pikitup is currently
running a recycling pilot project in the
Waterval area (western Johannesburg) in
conjunction with Mondi, which provides
vehicles to collect recyclable waste. Pikitup
Waste needs to be separated at source and items that don’t need to go to landfill need to be recycled

Solid waste
As they are the world’s best natural
recyclers of biological waste,
earthworms can be used to convert
wet waste on a large scale.
Their main function when converting waste
is to create a pathogen-free micro-organism-
rich soil conditioner, which improves soil
fertility. Pilot projects have been carried
out with Gauteng Provincial Veterinary
Health Services on the safe reduction and
conversion of abattoir offal and condemned
material using earthworms. The large-scale
use of earthworm compost and castings
(produced from wet waste) can rehabilitate
degraded mining and agricultural land in
South Africa.
Scientific studies have shown that by
increasing the life in the soil, erosion is
stopped, groundwater is purified, the air is
cleaned and carbon is locked into the soil,
where it belongs.
Earthworm factsIt is estimated that there are at least 3 500
species of earthworm throughout the soil on
the planet. They are very specific to location,
habitat and environmental conditions and
can be described according to the level of
soil they occupy and their feeding behaviour.
According to M Bouche (1977) earthworm
types are described as follows:
• Epigeic types – are surface dwellers
that live in freshly decaying plant or
animal residues.
• Endogeic types – live within soil and feed
on degraded organic matter present in
the soil.
• Anecic types – burrow deep in the soil, but
come to the surface at night to forage for
freshly decaying residues.
In South Africa we have approximately
300 species; the longest is 3 m and can be
found in the Eastern Cape area. Earthworms
are hermaphrodites and all are sensitive
to UV rays. The earthworm falls under the
animal kingdom, not the insect.
Earthworm anatomyThe body structure is basically a hollow
tube, albeit very complex. Earthworms
use a ‘hydraulic’ system to move around,
hence the importance of moisture
replacement. The haemoglobin in their
blood absorbs oxygen efficiently through
the skin. They have no immune system
and this is possibly one of their most
important characteristics: they ingest
harmful pathogens and digest them in order
to grow their own bodies. Their movement
in the soil introduces air and helps create
an oxygen-rich environment that makes it
possible for beneficial bacteria to multiply.
Protozoa, bacteria, ciliates, fungi – all these
microscopic organisms thrive and push out
South Africa is currently experiencing enormous environmental problems such as degraded soils, polluted groundwater and air, which have led to a serious global problem: greenhouse gas. But earthworm waste management can address these issues. by CC Nottingham*

the anaerobic pathogens, thanks to the role
of the earthworm in that environment. It has
also been discovered that the earthworm’s
excretion is 10 times more nutrient rich
than what is ingested, specifically because,
due to the presence of beneficial micro-
organisms which are increased 1 000 times
while passing through the worm’s gut, food
state nutrients (i.e. nutrients available to
plants) are created.
Analysis of worm castings showed

Commercial worm farmingThere are three or four species commonly
used to create compost and castings on
a commercial scale, mostly because of
their high rate of reproduction and dense
population in enclosed conditions. The other
species live in and ingest soil, and need
large areas in which to move, therefore
creating healthy soil in situ. The most
studied earthworm species, widely used and
established worldwide is the Eisenia fetida.
During the Olympic Games in Sydney,
Australia, in 2000, all food waste, sewerage
and paper products were processed by
earthworms. At the Bhawalker Earthworm
Research Institute in Pune, India, they
have successfully developed waterless
earthworm toilets and sewerage treatment
facilities. In Minsk, Russia, they reportedly
have the largest waste treatment facility
using earthworms.
Due to the effects of the Chernobyl
Nuclear Plant accident about 25 years
ago, the Eisenia fetida has become the
most-researched earthworm and even the
radioactivity in those soils have been found
to be best contained by earthworm activity.
France and the United States of America also
have large-scale earthworm plants.
With the advent of environmental
science, born as a result of the impact of
environmental degradation, loss of habitat
abd large-scale extinction of many species,
mostly due to our actions, the global
environment has our attention.
It is in this light that earthworms and their
products have become mainstream, and
the time has come in South Africa where
we are very aware of their importance
in maintaining healthy soil, now that the
repercussions of ‘dead’ soil have been
linked to massive erosion, groundwater
pollution, large-scale farming failures,
adverse weather pattern changes – and
even global warming.
Throughout the years, scientists have
studied isolated characteristics and effects
of earthworms and compost. Many papers
have been written, too numerous to mention.
At North West University in Potchefstroom,
trials have been carried out on the efficacy
of earthworms to convert contaminated soils
from gold mine tailings dams.
The earthworm and soil life In the 20 years of my involvement with
earthworm farming, the focus has been
mainly on the creation of a product –
registered with the Department of Agriculture
as a ‘group 2 fertiliser’ for the soil.
This classification, due to the empirical
approach of laboratory analyses, measures
but a small window. With the technological
advancement of electron microscopy and
its application to soil analysis, a whole new
world has opened up to us – the complex
web of life of micro-organisms and hence
a greater, complete picture of soil life,
health and the resulting environmental
consequences have emerged. Thanks
are due to Dr Elaine Ingham and the
International Soil FoodWeb Institute. In
summary, earthworms live in and convert
biological waste into a soil-enhancement
product – discovered due to the role of the
micro-organisms. Earthworm products are
classified as follows:
• vermicompost and vermicastings from
the breakdown of organic matter (mainly
plant matter and manures)
• liquid leachates or worm tea/wee
• worm bins of varying sizes and
shapes (domestic, commercial, large-
scale farming)
• doggie-loos, and others.
Safe management of abattoir wasteInitial enquiry 2006
Based on some articles that were written in
2005 and 2006, I was approached by
Dr Soni and Dr Louro of the Gauteng
Veterinary Health Services, who at the time
were compiling a Guideline Manual
for Abattoirs. This meeting was about the
use of earthworm technology to manage
abattoir waste.
This has led to an interesting journey
where the focus is not only the management
of a toxic, hazardous and extremely pollutant
waste, but the possibility of its conversion
into an environmentally safe (pathogen-free)
and therefore usable, soil conditioner.
Pilot research 1: June, July 2006
Armed with this question, we immediately
set upon experimenting on a small scale – in
two plastic boxes approximately 600 x 300
x 350 mm. Although this was carried out
with the sanction of the Veterinary Health

Solid waste
Services, it took three months to obtain 1
kg of carcass meal and 1 kg of blood meal
from an abattoir due to the red tape involved,
especially when it was for something ‘outside
the box’.
The first results registered a failure in
that within a short space of time, all the
earthworms turned either luminous yellow
from the carcass meal, or a deep red from
the blood meal, and all of them died. The
obvious conclusion was that earthworms are
not carnivores. They do not ‘eat’ the matter
itself, but rather go for the micro-organisms
that are present in decaying matter. In this
case, the fat and the blood then needed to
be pre-digested by micro-organisms to be
made ‘safe’ for the earthworms.
Pilot research 2: October 2006
The next step was to compost the carcass
meal and the blood meal for a period of
time, and then earthworms were introduced.
Although they hesitated to move in, they
eventually settled in. Our conclusion was that
by ensuring the presence of micro-organism
activity, earthworm composting was possible,
but we needed to up the scale.
Pilot research 3: 2007 – 2008
Then followed months of delay. Because we
wanted to do everything above board, as we
were working in conjunction with Gauteng
province, we approached a reputable abattoir
and the local environmental departments,
both municipal and provincial, to request
permission for our official pilot to take place.
The Department of Environment kept shifting
us from one person to another; we could
not get anyone to, firstly, determine how
much abattoir offal we could transport and
use in the pilot (our request was for 1 t),
and, secondly, find a person/department
that would grant us that permission. It was
the same with the local municipalities’
environmental departments. We had the land
and the methodology and, through Gauteng
Veterinary Services, we had access to testing
from the Onderstepoort Labs. However, we
needed the permission to run a pilot.
Presentations, written motivations and
requests to the various departments
eventually resulted in written responses
that we would not be granted permission
to run a pilot without first undergoing an
Environmental Impact Assessment.
It was not feasible for us to do this for
the small quantities involved to run a pilot
test. We were totally stumped and turned
back to Gauteng Veterinary Health. After
deliberation, the State Vet himself (Dr
Louro) and his colleague, Dr Soni, gave us
written permission sanctioning our actions.
The obvious conclusion was that earthworms are not carnivores
A WELL COACHED
TEAM IS A
WINNING TEAM
RéSource May 2012 – 17
But the pilot was limited to half a tonne of
offal and, instead of the numerous tests
that would be done by Onderstepoort Labs,
they would do only two: for E. coli 0157
and Salmonella.
Concurrent to this, we decided to run an
unofficial trial on our own. We ‘found’ 500 kg
of offal from a small abattoir (to remain
unnamed), mixed it with manure and greens,
and composted it for a few months.
Regular temperature, moisture and pH
readings were taken. This was then fed to
the earthworms with moderate success.
Moderate because as it was an unofficial
pilot, the results carried little weight.
During this time, however, (2007 and
2008) I was regularly invited to be a guest
speaker at many abattoir-government-related
conferences and open days in Gauteng,
Mpumalanga, Limpopo and the Northern
Cape. We also had a hearing at the Gauteng
Legislature in May 2008. The word, or
rather the ‘worm’, was spreading – several
large abattoirs had started composting
their offal, instead of the usual practice of
burying or landfilling it.
The National Environmental Management
Bill was grinding its way towards becoming
an Act.
Official pilot 4: 2008-2009
This pilot is the thesis for an Honours
Degree by a Gauteng Vet, Jack Motshegoa
and his thesis subject was approved at
the end 2008. In February 2009, armed
with the necessary letters of permission,
signed undertakings and Memorandums
of Understanding between the various
provincial and municipal departments, as
well as the ‘official’ abattoir and ourselves,
we collected the 500 kg offal and set up
the pilot.
Tests were carried out by Ondestepoort,
Nvirotek Labs and the Soil FoodWeb
Institute. The results were handed to an
expert on compost (Mr Dahan) and his con-
clusion was that ‘it is a good product’ – see
Table 2.
ConclusionNEMA (National Environmental Management
Act) 2009
According to the Waste Hierarchy (right),
NEMA has opened the doors for different
thinking to take place across all walks
of life, from industry and commerce to
domestic, as each section of society has to
find every means possible to prevent (or at
least to minimise) disposal to landfill. This
opens up many opportunities for renewable
operations to establish themselves – see
Table 3
Recycling, conversion and treatment of
various ‘wet’ waste streams
On a very small budget, and therefore
rather informally, it has been proven that
earthworms can be a vital link in the reduc-
tion of certain wastes that would normally
either go to landfill or be buried, namely
abattoir offal, manure and sewage, and veg-
etative matter.
Rehabilitation of degraded lands
In addition, NEMA places the responsibility
on the owners of land to rehabilitate the land
after use to “its former state”. Whether or
not this seems possible or feasible, it never-
theless opens many opportunities for doing
things differently.
The Global Carbon Credit Exchange
platform is just one such means to link
recycling and treatment (prevention of
disposal) of major existing waste streams
through the use of Earthworm Technology,
and also help clean up degraded lands with
the resulting product.

ACKNOWLEDGEMENTSDr Louro and Dr Soni of the Gauteng Department of Agriculture, Conservation and Environment (Veterinary Public Health) – in asking the question of whether or not earthworms can be used to recycle abattoir waste – have initiated the exploration and helped make possible the findings of this project. Although no sponsorship has been received, the project has continued for four years as the basis of a feasibility study for the business Earthworm Waste Management. This is a Section 21 Company, whose mission is to rehabilitate the environment (land, air and water) through earthworm waste management and thereby positively impact society. Its aim is the reduction and management of wet or biological waste to become the leaders in environmental regeneration.

FISCAL 2011 A MOMENTOUS YEAR FOR PETCO
The latest statistics reveal that over 1.4 billion PET bottles are being recycled across South Africa, which equates close to 4 million bottles recycled every day. In addition, PETCO exceeded its PET plastic recycling rate for 2010 by 5 290 t.
Recycling
PET recycling grows despite tough trading markets
collected in the first year to well over 1
billion bottles recycled in 2011. We’ve
have assisted in the establishment of over
430 plastic recovery stations throughout
In 2011, PETCO celebrated its sixth
anniversary and its efforts over the past
year were evident in the outstanding
recycling figures. While the world was still
recovering from the economic recession,
polyethylene terephthalate (PET) recycling
figures in South Africa continued to grow
despite tough trading conditions, and the
organisation is therefore proud to announce
that in 2011 it achieved an annual PET
recycling rate of 42% of post-consumer
beverage PET and 29% of total PET. A
total of 42 651 t of PET was collected and
recycled out of a 145 000 t 2011 resin
market. PETCO also tracked the recycling
rate, including pre-consumer material, and
the tonnage collected and recycled in 2011,
including pre-consumer, equalled 46 276 t,
representing 46% of beverage PET and 32%
of total PET.
Credit where it’s dueThese achievements would not have been
possible without the voluntary financial
support from PETCO’s members. By paying
the recycling levy and other contributions
through grants-in-aid, the PET converters,
bottlers, raw material producers and Coca-
Cola South Africa have all helped PETCO to
be the benchmark for Extended Producer
Responsibility and to reduce the volume
of post-consumer PET plastic in the waste
stream bale-by-bale, year-by-year.
The organisation achieved this recycling
rate in partnership with contracted service
providers, Extrupet, Kaymac and Sen Li Da,
which combine collection, recycling and end-
use in their PET value chain.
Cheri Scholtz, CEO of PETCO, says:
“Over the past six years we’ve gone from
9 840 to 42 651 t of post-consumer PET
bottles recycled or from 324 million bottles
South Africa and supported training of
staff at these drop-off sites. We have also
been involved in numerous separation at
source and school education projects. The
organisation has grown its targets from 16%
to 46% of beverage PET recycled, from 87
000 to 145 000 t of PET resin produced,
from small to large amounts of recycling
levies collected and income opportunities
created, from success to success.” In
addition, the organisation has helped
generate almost 26 000 indirect jobs across
the country. As far as carbon is concerned,
recycling 1 t of PET saves 1.5 t of CO2, so
the total carbon saved via PET recycling is in
excess of 63 000 t of CO2.
A winning formulaThe organisation’s 28 shareholder and 42
associate members have contributed to job
creation and skills development. PETCO

Recycling
post-consumer packaging plastics do not end
up on landfill sites.
Last year also saw the organisation support
projects with a strong focus on public and
consumer-based education and awareness
programmes, and these initiatives and
activities contributed to the visible recycling
of PET. Many of these programmes, such as
beach clean-ups, trade shows and workshops
for members on topics such as designing
PET bottles and containers with recycling
in mind, were convened in Cape Town,
Johannesburg and Durban. Together with
major retailers Woolworths and Pick n Pay,
PETCO has recently established the Retailers
for Recycling Forum, which aims to minimise
the environmental impact of post-consumer
packaging on the South African landscape
by creating awareness among consumers of
recycling issues and supporting retailers as
they work with their own suppliers to ensure
that packaging is designed with reduction,
reuse and recycling in mind.
Looking aheadIn 2012, PETCO needs to meet the targeted
tonnage of post-consumer beverage PET
recycled of 48 356 t or 44% of all beverage
PET resin converted, assist with the
establishment of more collection and drop-
off centres, and progressively build recycling
awareness through compelling and focused
messaging. There has to be a vigorous and
cost-effective strategy from both the public
and private sector.
has also provided millions of rands worth of
financial support to PET recycling companies
and in doing so has managed to expand
both bottle-to-fibre and bottle-to-foodgrade
recycling. “Built on the simple principle of
establishing an industry-driven and -financed
environmental solution for PET, the PETCO
model is now proven to be expandable and
sustainable,” says Casper Durandt, senior
technical operations manager for Coca-Cola
South Africa and PETCO chairman.
According to Scholtz, 2012 will certainly
prove to be a turning point in the
organisation’s development as this will be
the first year that PETCO will be facing a
shortage of end-use market applications for
recycled PET, with the local bottle-to-fibre
market now reaching saturation and local
recyclers have reached capacity. “This means
that as more and more post-consumer PET
bottles are collected, so end-use markets
need to expand and develop,” she explains.
South African PET recycling is unique in that
almost all of the post-consumer PET bottles
collected are recycled into a local end-use
(mainly fibre and more recently bottle-to-
bottle) and not exported to China, as is done
by many other countries.
The largest end-use market for post-
consumer PET bottles in South Africa is
currently the fibre market (bottle-to-fibre).
More recently, there is installed capacity for
post-consumer PET bottles to be recycled
into new bottles (bottle-to-bottle). Bottle-
to-bottle resin take-up is, however, still
relatively slow and PETCO is working with
retailers and brand owners to increase the
demand for PET recyclate.
Industry and consumer initiatives During 2011, PETCO worked closely with
the Recovery Action Group on drafting the
Industry Waste Management Plan for the
packaging and paper industries, the main
co-regulatory instrument within the waste
management system.
At the same time, PETCO now chairs
the newly formed Sustainability Council
of Plastics SA, providing leadership to
the plastics industry in order to reduce
carbon emissions, be more energy effi-
cient, cut transportation and ensure that
In 2012, PETCO needs to meet the targeted tonnage of post-consumer beverage PET recycled of 48 356 t or 44% of all beverage PET resin converted
GENERAL FACTS• Approximately 33 bottles = 1 kg PET
• The fibre for a standard pillow can
be made with nineteen 500 mℓ PET bottles
• According to the UK-based recycling
organisation Recoup, if plastics
were no longer used in packaging,
the weight of packaging materials
would rise by 300%, the volume
of rubbish would expand by 150%
and the energy consumed by the
packaging industry would increase
by 100%.
• Statistics say approximately 12%
of household waste is packaging
waste. Estimates are that some 3%
of this, by weight, is plastic bottles
(estimated to be 100 000 t for
2012 in South Africa).
• Recycling 1 t of plastic bottles
saves 1.5 t of CO2, and decreases
the need for raw materials, thus
saving energy.

Panel discussion
Recycling and the sustainability ‘food chain’There’s more to recycling than separate, drop and go!
Sustainability – the industry buzz word
that’s on everyone’s lips. From small
companies to large corporates, it
seems that everyone is jumping on the green
bandwagon. In spite of the numerous ways
that sustainability can be adopted, from basic
energy and water conservation through to
complex green building designs, none is more
popular than recycling initiatives. But while
businesses and industries have and continue
to establish effective recycling programmes,
the everyday consumer in South Africa still
battles with the concept. This is mainly due
to the fact that recycling at household level in
South Africa can prove to be quite a daunting
task as the infrastructure for collecting
recyclable material isn’t quite where it should
be. Although municipalities are geared to
implement domestic separation at source
kerbside collections, until this is properly
enforced, households are left to separate
their rubbish and take the recyclables to
a municipal drop-off or buy-back centre.
Despite the setbacks, this hasn’t deterred
industry role players who continue to embark
on recycling campaigns, which aim to educate
and create awareness among consumers and
the youth. But recycling doesn’t just include
solid waste; what about the proper disposal
and recycling of e-waste?
Candice Landie facilitates this panel discussion, which looks at the initiatives and projects that role players are involved in at both consumer and industry level, including the outcomes of these campaigns. The discussion also highlights how Extended Producer Regulation can affect manufacturers of recycled products and packaging.

Q. What is Desco’s core business function?A. Desco is a specialist recycler
of e-waste consisting of waste
electrical and electronic
equipment (WEEE). As an
established e-waste recycler
celebrating 20 years of recycling
in this industry in South Africa,
using clearly defined processes
and procedures based on
our ISO 14001 certification
and standards, we are able
to offer our clients a one-
stop solution for their e-waste
recycling requirements. As it
is impossible to recycle all the
identified waste streams on site
in a sustainable and responsible
manner, Desco Electronic
Recyclers uses approved,
specialist downstream vendors,
to effectively recycle the
different categories of waste
fractions, such as ferrous and
non-ferrous metals, plastics,
paper, cardboard and cabling.
Q. What initiatives is Desco involved in at consumer level to promote the recycling and proper disposal of e-waste? A. The following projects have
been in place for the past two
to four years:
Makro Stores: Makro stores
nationally have specialised
6 m closed containers on site
for their customers, who can
place all e-waste products
into the bins for collection
and responsible recycling by
Desco. The initiative started as
a joint venture between Fujitsu
Siemens, Makro and Desco
Electronic Recyclers in 2008.
Incredible Connection: all
stores nationally have a
1 000 ℓ capacity wheelie bin
for their clients to place their
e-waste into, for collection and
responsible recycling by Desco.
Incredible Connection also uses
the wheelie bins as a marketing
opportunity when they run their
trade-in promotions on an annual
basis, encouraging clients to
PANEL DISCUSSION
bring in their old and used
e-waste and receive a discount
on new goods purchased.
Hi-Fi Corporation: currently has
15 stores nationally that have
wheelie bins, similar to those of
Incredible Connection, for their
clients to place e-waste into.
School projects: Acer and Miss
Earth South Africa have bins
placed at six schools in and
around Johannesburg where
pupils bring their e-waste from
home, place it in the bins, which
when full are collected and
emptied by Desco.
Holy Rosary School: Incredible
Connection and Desco have
a 6 m container placed at the
school, offering pupils and the
surrounding local community a
drop off point for their e-waste.
In this initiative, pupils from
the school’s eco committee
manage the entire process of
marketing the initiative and have
launched competitions to create
awareness around the need for
responsible e-waste recycling.
Miss Earth South Africa (in
association with Consol): Desco
has been working closely with
the Miss Earth South Africa
platform to promote awareness
regarding the importance of
e-waste recycling in South Africa.
Q. What is Desco doing within the waste industry to promote recycling and proper disposal? Has the new Waste Act helped increase recycling statistics?A. Desco is interacting more
and more with other role players
within the industry, investigating
synergies and possible
collaborations that can bring
about awareness and education
to understand the importance of
e-waste recycling. As this is the
fastest growing waste stream
within the waste management
arena, it is important for role
players within the industry to
work together on offering more
value-added services to the
consumers, and look at joint
strategies to ensure a steady
growth in the awareness around
the importance of e-waste
recycling. The new Waste Act is
increasing awareness at industry
level, ensuring that the captains
of industry are concerned about
recycling and/or disposing of
their e-waste in a responsible
and controlled fashion,
eliminating the need for sending
e-waste to landfill, as has been
the case in the past.
Q. Desco prides itself on environmental excellence by providing a high-quality service for the disposal of electronic waste. Briefly explain how you ensure this service is always conducted in an eco-friendly manner?A. As Desco has been in the
business of recycling e-waste
for 20 years, we have refined
the art of doing business in this
industry based on excellence
and integrity. Desco is able to
offer this service on an ongoing
basis, based on the following
conformity, compliance and/or
certification, namely:
• ISO 14001 certification
as certified by SGS, an
international auditing company
• Section 20 permit of the
Environment Conservation Act
(Act 23 of 1989) as amended
• compliance to both ISO 9001
and OHSAS 18001: we will
be striving for certification in
OHSAS 18001 standards by
the end of 2012
• recycling authority permit
from Gauteng Department of
Agriculture and Environment
(permission to operate a
recycling facility)
• all our vehicles and drivers are

PANEL DISCUSSION Zimasa Velaphi, PR/marketing manager, Collect-a-Can
Q. What is Collect-a-Can’s core business function?A. Collect-a-Can was established
in 1993 by shareholders
ArcelorMittal South Africa
(tinplate producer) and Nampak
BevCan (steel beverage can
manufacturer). The main
aim is to recover, recycle
and reuse metal cans from
the environment as a litter
abatement and environmental
responsibility project.
Q. Collect-a-Can has a very impressive schools programme and competition running? Can you briefly explain this initiative?A. Collect-a-Can’s philosophy is
that the culture of Responsible
Waste Management through
recycling needs to be inculcated
from a young age for it to become
normal behaviour in South Africa.
One of the vehicles is through
the school’s competition that we
currently run in four provinces:
Gauteng, Western Cape, KwaZulu-
Natal and the North West.
The National Schools
Competition: This is our flagship
competition; it operates in six
Collect-a-Can branches within
South Africa. Schools can
raise funds for themselves by
collecting used cans and stand
a chance to win monthly and
annual prizes, while creating
environmental awareness and
cleaning their community. The
school that collects most cans
per child and per school wins
a prize.
Can Craze Competition: An
exciting competition that
encourages pupils to create
structures or characters using
beverage cans. Through this
exciting team exercise, learners
are required to collect at least
300 cans and use them to build
a structure.
Artistic Competition: This year
we’ve introduced this to tertiary
institutions, where students can
design our logo and create the
new campaign line.
Q. Consumers aside, what is Collect-a-Can doing at industry level to promote recycling and reduction to landfills? A. Apart from recovering

PANEL DISCUSSION
Q. What is Remade’s core business function?A. Remade provides a multitude
of waste management services
specialising in the minimisation
of waste streams and the
collection of recyclable waste.
Q. What initiatives is Remade involved in at consumer level to promote recycling? Do you educate consumers on what can be recycled and how so?A. Remade Recycling provides
Waste Management services
to Commerce & Industry
and promotes recycling to
each of our customers who,
in turn, promote recycling to
their customers.
We do, however, provide an
offtake for most recyclable
products and promote
separation at source of
recyclable and non-recyclable
waste. We encourage recycling
by putting a good market-
related price on all recyclable
material and giving clear
descriptions of what can and
can’t be recycled. We buy
recyclable materials at all our
buy-back centres and branches.
Q. Do you have buy-back centres in Gauteng only? How many and in which areas?A. We currently have 30 buy-
back centres and we buy
recyclable material at the
nine Remade branches as
well. In total we buy back
from the public at 39 centres.
Our branches are located
in: Germiston, Jeppestown,
Newtown, Pretoria, Wynberg,
Springs, Randfontein,
Rustenburg, Klerksdorp,
Witbank and Nelspruit. We also
have operations in Polokwane,
Vereeniging, Vanderbijlpark,
Midrand, Witbank and
Nelspruit. Anyone who is
interested in taking their
recyclables to a buy-back centre
can contact our toll-free number,
0860 736 233, to find a buy-
back centre in their area.
Q. What types of recycling containers/bins are available to your customers?
Is the type of container environment/area specific?A. Bulk containers are available
to industry in different sizes,
that is, 6 m³, 9 m³, 11 m³ and
30 m³ containers and cages.
We supply bags for smaller
customers andprovide cardboard
boxes for office recycling. These
containers are not environment
or area specific, but they are
volume specific.
Generators of large volumes
of recyclables would obviously
receive larger containers.
Q. Do you work with street harvesters/hawkers in the collection of recyclables? How so?A. Yes, we are supplied by
thousands of street harvesters
per day. As mentioned, we buy at
39 centres and each is supplied
by approximately 100 people per
day. They deliver their material to
us and we pay them per kilogram
for all recyclable waste delivered
to a buy-back centre.
We provide training in the
identification of all recyclable
waste to encourage harvesters
to collect as many grades of
recyclable waste as possible.
We provide opportunities
for harvesters to get further
involved in our business and
help to develop them in such a
way that they might one day own
their own Buy-Back Centre.
Q. Consumers aside, what is Remade doing within the waste management industry to promote recycling and reduction to landfill?A. Firstly we needed to make
sure that we are fully compliant
with all aspects of the new
Environmental Waste Act of
2009. I’m happy to say that we
have been very successful in
doing so. We have also created
a division within our Business
called Remade Onsite. This
division offers sustainability and
management programmes to
commerce and industry.
In light of the New Waste Act,
Remade Onsite provides a full
waste management service,
which includes:
a. separation-at-source,
b. retrieving all recyclable material
from a customer’s waste stream,
c. Managing the disposal of all
different waste to the correct
landfill, such as hazardous,
non-hazardous, redundant
stock, etc
We thereby minimise waste
disposed at landfill, thus
ensuring that our customers
remain compliant.
We then created a division called Remade Onsite which offers sustainability and management programmes to commerce and industry

GAYATRI PAPER MILLS1 Power Str, Germiston, Gauteng
Tel: +27 11 821 8600
NOW! Tetra Pak is proud to announce the commencement of local carton
recycling in South Africa with Gayatri Paper Mill, based in Johannesburg. The
last drop of milk or juice does not mark the end of a cartons’ useful life. Used
cartons are a valuable resource-easily recyclable and much in demand.
HOW? Waste management and collection companies throughout South
Africa are encouraged to collect and bale used cartons for resale to Gayatri
Paper Mill. Recycling takes place at Gayatri with a hydro-pulping process
which separates the paper fibre from the polyethylene and aluminium.
The recycled fibre is then used to make a range of cardboard products.
The poly/alu component is separated for aggromulation and pelletisation for
use in plastic injection moulded products.
WOW! In addition, carton packaging is made mainly from paper
board, a natural renewable resource. In fact carton packaging is the only type
of packaging made mainly from renewable materials which gives our
packaging a low carbon footprint.
When the contents are gone,
YES! Cartonsare Recyclable!

PANEL DISCUSSION
Q. What is Tetra Pak’s core business function and what products and services does the company offer?A. Tetra Pak is the world’s
leading supplier of food
packaging and processing
equipment. It was established 60
years ago, supplying packaging
suitable for long-life milk, juice
and other food products. The
company also supplies the food
processing and filling equipment
required for its packaging.
Q. What initiatives are Tetra Pak involved in at consumer level to promote reuse and recycling of its packaging products?A. Cartons can and are being
recycled here in South Africa at
Gayatri Paper Mill in Germiston.
The hydro-pulping technology
was developed by Tetra
Pak’s engineers and involves
the separation of the paper
board from the polyethelene/
aluminium. The fibres (pulp),
once separated, are used to
manufacture cardboard boxes
and other paper products, while
the polyethelene/aluminium is
processed into ‘pellets’ suitable
for injection molding. Most
consumers in South Africa are
unaware that cartons can and
are now being recycled, so we’ve
started communicating this to
them through:
• on-pack messaging
• point of sale promotions
• schools educational
programmes
• collection programmes with
waste management companies
and collectors
• PRASA (Paper Recycling
Association of South Africa)
• leaflets
• drop off recycling centres
• websites.
Q. What effect has Extended Producer Responsibility in relation to the new Waste Act had on Tetra Pak? A. Tetra Pak has been a member
of RAG (Recovery Action Group
of South Africa) and has
worked very closely with all
the other industry associations
to formulate plans for the
efficient and proper collection of
packaging waste in South Africa.
We understand that we have a
responsibility to ensure proper
environmental solutions for our
packaging and will continue to
do so with the brand owners
(for example, Clover, Parmalat,
Ceres and other retailer brands)
using our packaging.
Q. Tetra Pak considers its packaging design to be environmentally sound and sustainable. How so? A. Our cartons are made
of paper board, a natural,
renewable resource. This gives
our packaging a lower carbon
footprint compared to other
types of liquid packaging.
Our long-term goal is to ulti-
mately supply packaging derived
from 100% renewable materials.
We measure our environmental
impact throughout the entire
value chain, from the sourc-
ing of raw materials (mainly
paper board), the manufactur-
ing of laminated board at our
converting factories, the pro-
cessing and filling equipment
used by our customers, to the
distribution of our packs into
retail, and then once consumed,
ensuring that cartons can
be recycled.
Q. With regards to packaging technology, what is meant by Environment Product Declaration Certified, and how does it fair in terms of energy and water reduction?A. Tetra Pak set a climate goal
objective in 2005 to reduce
carbon emissions by 10% by
2010 and ended up achieving a
13% reduction, despite growth
during this period.
New targets have been set
to further reduce emissions
by 2020, measuring impact
throughout the value chain.
Q. Consumers aside, what is Tetra Pak doing within the waste management industry to promote recycling and reduction to landfill?A. Tetra Pak works with packaging
councils, industry associations,
NGO’s, governments and others
internationally to ensure that
waste to landfill is reduced. The
situation is no different in South
Africa. Tetra Pak worked as a
member of RAG, and together
with all the industry associations
formulated the IWMP (Integrated
Waste Management Plan) that
was submitted to government for
approval. The plan encourages
separation of waste at source
(consumer) and then for the
waste to be collected separately
and taken to a Materials
Recovery Facility where it
will get separated, baled and
sold to recyclers. The plan, if
implemented, will reduce waste
to land fill and create thousands
of jobs nationally.

LANDFILL GAS PROJECTS
The capture and destruction or utilisation of landfi ll gas is not a legislative requirement in South Africa, which opens the doors for the commercial sector to develop this resource in the warming climate of carbon credits and green electricity tariffs. By Dr M Griffith, K Naidoo and M Saner
Landfills
The search for feasible landfill gas-to-electricity projects
So what is needed to extract the euros
and rands from society’s detritus?
Landfill site? Check! Trillions of
methane-producing microbes? Check! Proven
technology to extract the gas and produce
green electrons? Check! A local industry
with the experience and expertise to design,
build and operate the facility? Check! Check!
Check! Sadly, it’s not so simple, and the
problems lie in the nature of the landfill sites
themselves, the populations they serve, the
people who operate them and the officials
who regulate the entire chain. Landfill sites
are good projects, with great economic and
ecological benefits; however, a landfill site
does not automatically equate to positive
financial returns and the correct sites must
be chosen.
CEF (Pty) Ltd is a private company owned
by the Department of Energy with a mandate
to search for appropriate energy solutions to
meet the future energy needs of South Africa.
Through the feasibility study of a basket of
20 wholly-owned landfill sites, some valuable
lessons have been learnt on the assessment
of site feasibilities, and being able to tell the
difference between good sites and bad sites
may save time and money.
The feasibility study approachA five-pronged approach is taken in the
development of the bankable LFG feasibility
studies: technical, environmental, legal,
clean development mechanism (CDM)
and financial.
The following activities form part of
each group:
1 Technical – split into two stages, namely
prefeasibility and detailed feasibility
studies.
2 Waste licence and environment study –
the Act regulating landfill gas utilisation
changed from the National Environmental
Management Act of 1998 to the National
Environmental Management: Waste Act of
2008. Consequently, the environmental
methodology changed from a full EIA
to a waste licence application and
basic assessment.
3 CDM – the CDM was chosen as the
system through which the carbon will be
traded due to the higher prices that the
Certified Emission Reductions (CERs)
commanded. The CDM process includes
a methodology assessment, Project Idea
Note, Project Design Document, validation,
CDM registration. Verification of the CERs
forms part of the site operations.
4 Legal – the exclusive rights to utilise the
gas is granted through an agreement
with the municipality, in exchange for a
fair royalty payment. An important issue
is the land use agreement, with triggers
in the Municipal Finance Management
Act causing some lively debate around
the negotiations table. The two primary
revenue streams – the CERs and
electricity – will be secured using long-term
Emissions Reduction Purchase Agreements
and Power Purchase Agreements (PPAs).
5 Financial – Being a commercial endeavour,
the project must generate sufficient
returns to justify the risk of investment.
The technical study, gas flows with CER
as well as electricity generation estimates
and sale prices are combined with the
CAPEX and OPEX estimates to form a
financial model. The model is used to
evaluate the performance and determine
the viability of the project, which is taken
to the shareholder’s board for the final
investment decision.
A positive result for all five aspects is vital
to reach bankability; however the financial
performance has proved to be the greatest
hurdle. As the majority of these activities are
informed by the results of other activities in
other groups, the processes must parallel
each other in a carefully structured fashion.
The experience gained in conducting the 20
feasibility studies is shared below.
Experience shared• Landfill sites are not attractive
(investments): Although those in the know
will argue to the reasons behind it all,
the fact remains that landfill gas CDM
projects are renowned for under-delivery.
Worldwide, the figures are quite appalling
with 35% of the projected CERs delivered
from 48 projects (http://cdmpipeline.org/A fully functional landfill gas-to-energy plant
Landfills
cers.htm). According to Pierce (2009) the
over-projection of landfill gas extracted
was the cause for many project failures.
The challenge to the project developer
is to convince investors or finance
institutes that their project will deliver
as expected. From these experiences, a
more conservative approach is now being
adopted. On the flip side, the financial
institutions must ensure that the right
professionals are appointed for the due
diligence in order to recognise the level
of conservatism that has been adopted
and thus avoid excessive haircuts on
a project that has already been to the
army’s barber.
• Not all sites created equal: An obvious
statement for anyone involved in the
industry. However, a surprising number of
people believe that a landfill site equals
a landfill gas project. Be they ambitious
businessmen or municipal councillors,
these expectations must be properly
managed and the developer often needs
to negotiate its way around the small and
shallow to find those sites that are ‘more
equal than others’. The sites that have
progressed to final bankability all have
the following in common: in-place volume
of more than 1 million cubic metres,
an annual disposal rate of more than
200 000 t and the receiving of waste for a
few years into the project.
• The fuel: To quote a waste-to-energy
professional (McKendry, 2008), it’s all
about the fuel. For a landfill gas project,
the organic waste is the fuel for the
production of biogas. Those industrious
microorganisms supply the methane in
a fairly reliable concentration of about
40 to 60%; however, it’s the quantity
that concerns us the most and methane
formation needs degradable organic
material. Although one can be reasonably
assured that the large general waste
sites will receive organics, be sure of the
proportions of the various waste streams
as a high percentage of inert materials
may mean the difference between a fizzer
and foreclosure.
• Open sites are better: As per the previous
point, the gas supply is dependent on
the incoming waste. Stop the waste and
the gas supply will also cease. Due to
the nature of the organic processes, the
decline is a somewhat drawn-out process
with a half-life (50% of the initial gas flow)
of about five years post closure. This has a
profound effect on the commissioning and
operation of the generation equipment as
the gas engines’ performance deteriorates
when operated below 50 to 65% of
the rated capacity. Hence, if the site is
closed, some sort of engine swapping will
be required. Conversely, open sites will
release gas at a more steady rate, which
can be exploited through ongoing gas field
development. Furthermore, a gas engine
operating at a de-rated capacity will provide
less return for the CAPEX outlay and is a
problem for both open and closed sites,
which can only be resolved through a cost-
benefit analysis.
• Good data is like hidden treasure: Reliable
data can be difficult to find, but it’s worth
finding. Municipal departments often
don’t have readily available access to
the information, but their consultants do.
Add the large number of consultants that
have been appointed by the municipalities
(generally due to procurement processes)
and one often needs to contact many
different professionals in order to retrieve
the information. Despite the advancements
in remote data access that the cyber age
has brought us, the most reliable method
of collecting the info is still physically
visiting the offices. All information
should also be thoroughly interrogated
– weighbridge data is a prime example
as when questions were asked about
the apparent low tonnages at one site,
the response was: “Ja, the site opens at
07:00 but the weighbridge operators only
arrive at 08:30.”
• Local knowledge is vital: South African
waste professionals are excellent; they
know the sites, know the process and
they now have the knowledge to design
and implement landfill gas-to-electricity
projects. Although the technology is
still based on international practices,
a South African engineer can tell you
which manhole cover is more likely to be
stolen and understands concepts like
‘landfill compactor operator risk’. With

list of commissioned landfill gas projects,
currently around nine, the South African
industry is indeed gathering steam.
• Landfill sites are fickle: Although cause is
mostly due to the disposal patterns of the
populations they serve and the regulators
that govern them, an attractive site may
suddenly lose all appeal because the
disposal rate halves or the site is closed
early. This is certainly a challenge as one
progresses through a drawn-out feasibility
study with continual adjustments to the
design required. Significant changes
in disposal trends are sometimes
unavoidable, but can be picked up by
well-directed consultation with the site
owner and its landfill operations plan. As
one can only work with the information
available at the time, the development of
the site should remain conceptual for as
late as possible.
• Projects require patience: A LFG project
developer needs a deep pool of patience
and an even deeper pool of resources
if they wish to see any sort of project
dividend. The feasibility stage, waste
licence and CDM registration processes
are long, drawn-out affairs. When
commissioned, the municipal projects
should have taken more than three years
to implement. It must be said that the
pioneering efforts of the early LFG project
developers have helped significantly, and
these timeframes are getting shorter with
each instance. There are some delays,
however, which are unavoidable and may
catch some cash-strapped developer
unawares. Take CER revenues as an
example: the project is commissioned
and the carbon credits start to flow – not
true. The project is commissioned and the
CER monitoring process begins. After 6
to 12 months (depending on how urgently
you need cash flows) the verifiers arrive
on site, gather the data and write their
reports. More waiting is needed while
the credits are registered and finally
delivered. An 18-month delay between
the commissioning date and the first CER
cash-inflow should be expected.
• Take calculated risks: Linked to the
previous point, the development of
these projects takes time and the
commissioning of feasibility activities ‘at
risk’ is necessary to keep the programme
reasonably short. It is necessary to
identify what activities are required and
when they should be delivered. An EIA,
for example, needs technical information
from feasibility work, while the CDM
process requires feedback from the
EIA, technical study and agreement with
the municipality; the gas rights usage
agreement requires the completion of the
feasibility study. This web of information
transfer requires careful planning and
coordination for information to be
available when needed and to avoid
processes being repeated as a result
of incorrect assumptions being applied.
Additionally, if the project is taken to the
market too early, delays or changes in
figures may result in reputational damage.
• The markets change: In 2008 the projects
had a heavy carbon slant – CER prices
were in the teens and electricity prices
still Eskom-based (see Figure 1). Electricity
accounted for less than 40% of the
project revenues for the 10 years of CDM
registration. Now, the CER market is down,
but REFIT-based electricity prices are up,
with electricity sales accounting for over
65% of the revenue split. Incidentally,
a theoretical price of €15/CER (R154/
CER) would result in a 50/50 total
revenue split with REFIT-based electricity
revenues. Adding to the problem is the
exchange rate with the South African rand
‘pronking’ all over the euro. It’s great for
buying European services or equipment,
but most of the compliance buyers are
also European and the CERs are likely
to be Euro-based. The importance of the
CER revenues is still significant. The CER
revenues are required to make the projects
viable and the markets may recover to
the extent that the carbon surpasses the
electricity revenue, but while on holiday in
Greece you may want to take another look
at that PPA.
• The rules change: The final lesson is that

renewable energy is still a relatively new
player in a parastatal monopolised market.
Thanks to the state’s renewable energy
strategy (the white paper on renewable
energy) and, arguably, the more apparent
Eskom supply problems, the regulations
are adjusting to make development in the
energy industry more accessible to the
private sector. Public feedback is central
to these changes and it is advisable to at
best participate, or at worst be informed,
of the intended legislation. The end
result should be beneficial to the project;
however, the developer must be on the
ball in order to change the game plan if
and when required. We look forward to
a mature renewable energy sector with
an established process and many REFIT
projects delivering green power to the
citizens of South Africa.
ConclusionThe monetising of landfill gas as a
commercial project is a viable and
established undertaking; however, a
comprehensive feasibility study is vital
to ensure the projects that make the
cut are actually able to perform. The
licensing and approval processes makes
the commitment of feasibility funds ‘at
risk’ almost unavoidable if one is to keep
the programme relatively short and the
shareholders may face a long wait for the
first dividends. Changes in site operation,
legislation and markets make these projects
challenging developments and a certain
degree of ‘looseness’ is required to adapt
and move on. The feasibility processes
should be progressed, as recommended, in
a structured and responsible manner in order
to avoid redoing work and to preserve your
reputation in the market.
Finally, landfill gas-to-energy projects are
attractive projects, not only because of
good investment returns: the environmental
impacts of greenhouse gas and odour are
reduced, jobs are created and renewable
energy is delivered to a country that
desperately needs it.

TRANSFORMING WASTE INTO ENERGY, SAVINGS AND INCOME
While the concept of extracting energy from organic waste is defi nitely not something new, most people are of the assumption that these bio-energy solutions are only reserved for large refuse dumps and industrial-sized companies. This is not true. by Jonathan de Magalhães*
Waste to energy
Fuelling the biogas generation
Biogas is a combination of mostly
methane (CH4) and carbon dioxide
(CO2), and is created in the
process of anaerobic digestion, which is
the fermentation of organic matter in the
absence of oxygen.
Simply put, a biogas digester is a water-
tight tank which is fed with organic waste.
And the scope for usable organic waste is
huge: food and table waste, animal manure,
animal fat and blood from abattoirs, sew-
age and even grass cuttings are all perfect
candidates for biogas generation, to name
but a few.
Government support?Unlike some renewable bio-energy tech–
nologies that are fairly new, a quick Internet
search confirms that biogas digesters have
in fact been around for over 150 years. The
first biogas digester was built in Bombay,
India, in 1859 at a leper colony. Currently, it
is estimated that there are around 2 million
biogas digesters in operation in India,
while China supersedes that amount with a
staggering 6 million digesters estimated to
have been installed by 1970.
And yet, the idea of easily converting
organic waste to usable renewable energy is
virtually unknown in South Africa. Even other
African countries, such as Kenya, Tanzania
and to a lesser extent Botswana, have active
governmental assistance programmes in
place to assist in the easy deployment of
biogas digesters. In fact, here are more biogas
digesters installed in Lesotho than there are
in South Africa! In South Africa, the assistance
for any individuals, companies or communities
wanting to take advantage of a waste-to-
energy digester has been largely ignored by
government. As Mark Tiepelt from Biogas SA
observed: “Large-scale commercial biogas
digesters have huge potential, but the most
effective and highest impact way to establish
biogas as a viable sustainable alternative
source of energy is to support its application
of waste-to-energy in whatever way on farms.”
So basically put, don’t expect any financial
assistance from the government in the form of
a REFIT (renewable energy feed-in tariff) or IPP
(independent power producer) agreement.
Great potentialIsn’t it ironic then that the first large-scale
biogas digester privately built to generate
biogas was done by South African pig
farmer L John Fry in the mid-1950s. Known
worldwide, his agricultural digester ran a
bi-fuel generator on biogas for six years
non-stop before he moved to the United
Kingdom. But the good news is that, even
without any financial assistance, biogas still
has huge potential as being a very viable
solution, showing greatcost payback periods
for environments with suitable quantities of
organic waste available. The biogas that is
produced can also be used for a number
of different applications as well. Burning
the gas for heating is the most efficient
way of using biogas. Heating could be a
normal requirement, such as space heating
for ambient temperature control (crucial for
chicken farming in the winter), as well as
water heating. By using a biogas water heater
it is possible to provide instant hot water using
nothing more than your organic waste. Using
biogas stoves, rice cookers and other biogas
appliances that are readily available enables
normal food cooking to be done running solely
off biogas. Lighting can also be provided,
using biogas lights that work in exactly the
same way as a camping gas light.
Energy efficiencyWhile it’s not the most efficient way of using
biogas, running a biogas generator can also
generate electricity. However, the comment of

abundant biogas to generate electricity has
many advantages, regardless of the efficiency
process when running it through a biogas
generator. It was in fact these advantages that
took centre stage at the Bio-Energy session
at the Africa Energy Indaba 2012, recently
held in Sandton, Gauteng. The indaba was
a platform for energy stakeholders,solution
providers and professionals to get together
and look at the solutions available to assist
countries and projects throughout Africa who
are facing various energy challenges.
Biogas specialist, Jan du Preez, who was
at the Africa Energy Indaba, also commented
on the environmental impact of biogas
digesters noting: “Currently there is very little
precedence for EIA (environmental impact
assessment) studies for biogas digesters in
South Africa. If the digester is to treat manure,
sewage and energy crops, only a basic EIA
is required, provided the generation capacity
is less than 10 MW and the land area used
is less than 1 ha. However, if the digester is
to treat other wastes such as the putrescible
animal wastes from abattoirs, then a full EIA
may be required, regardless of the size of
the biogas digester”. So while deploying a
biogas solution can be done relatively quickly,
it is possible that the environmental impact
studies required could take some careful
planning into the roll-out schedule.
No such thing as trashOne of the main advantages of a biogas
system is that the organic waste that is usually
subject to strict health and safety procedures
can now be used to generate free energy.
For new developments, or where a septic
tank system is used, sewage can be routed
directly into the biogas digester. Besides
providing additional organic waste for biogas
generation, using sewage has the benefit
of providing most of the water required for
the biogas digester to function correctly.
Additional benefits include not burdening the
existing sewerage infrastructure system, as
all sewage can now be naturally processed
on site while generating biogas at the same
time. After the biogas has been generated,
the organic slurry produced by the digester
also has a commercial value as an organic
compost and fertiliser.
This can either be used on site if the
installation is on an agricultural holding, or it
can be sold either in its wet form or as dry
pellets to farms requiring fertilisers.
Therefore, a biogas solution offers the
advantages of taking freely available, and
sometimes problematic, organic waste to
generate energy, reduces existing energy costs
in an environment, and provides an additional
revenue stream in the form of creating natural
fertilisers, making the use of biogas a win--win
solution. There is energy in waste. And a lot
of it too!

Waste to energy
BUILDING A BIOGAS DIGESTERThe main components of a biogas digester are the inlet section, the digester tank and the outlet section, and building a small-scale biogas digester is a fairly straightforward process:• First, a hole is dug for the main digester tank. For a 10 m3 digester, this would be around 3.5 m by 3.0 m.• A collapsible shutter system is installed and the inlet and outlet sections are built into the digester tank. The
digester is then formed by pouring 25 MPa concrete over the shutter system.• The shutter system is collapsed and removed, and the inlet and outlet sections are completed and plastered.• A floating dome is then inserted into the digester tank. This dome will be underwater and collects the biogas as
it is produced. • As the dome is underwater, the biogas being collected is automatically under constant pressure, therefore
negating the need for any additional pressure pumps.• Finally, the gas piping is connected to the floating dome and the concrete covers and manhole plates are placed
over the digester tank.

Waste to energy
Energy from waste (EfW) represents
a favourable step towards achieving
complete waste diversion from landfills
– towards the widely used adage ‘zero waste’.
Arguably there will always be waste residues
to any waste treatment or disposal method
adopted – even landfills leak out large
volumes of biogas and noxious leachates.
Planning in South Africa encompassing waste
management plans for cities, metros and
government infrastructure must consider the
full waste hierarchy (as depicted in Figure
1). But to an energy intensive South Africa
(as well as energy-strapped South Africa),
recovery of energy (prior to final disposal) is a
step yet to be fully taken.
Cost analysisEnergy from waste technologies is, by and
large, either biological or thermal. Biological
treatment invoalves the Anaerobic Digestion
(AD) of wastes to produce a biogas for
energy. There are many AD technologies
available being applicable to specific waste
feed-stocks. Thermal processes are similarly
wide and the general descriptions are mass
burn, advanced thermal treatment, thermal
valorisation, pyrolysis, gasification. The
word ‘incineration’ is largely avoided – much
similar to the word ‘dump’ being avoided by
the modern landfills!
AD bankability: AD is, strictly speaking,
aligned to a specialised industrial treatment
process. Technical risk can be identified as
high by funding organisations, in particular,
the operational risks if a specialist operator is
not involved with the ‘AD kit’ implemented. In
comparison to energy outputs, capital costs
are high for AD.
A plant of about 12 000 tpa may offer
up to 500 kWe at a total capital cost of
approximately R30 million to R40 million. The
project financials can also be tough on AD
projects. In the United Kingdom for example,
where SLR Consulting has been involved
with the development of many AD projects,
the availability of Renewable Obligation
Certificates (ROCs) and the high cost of
landfill disposal are significant pushers to
an AD choice. An AD project locally would
have to be supported by a strong ‘gate
fee’, for mainly liquid wastes (avoiding
co-disposal to landfills). Energy sales may
also be significant particularly where a funder
could offer bankability of a Fuel Purchase
Agreement (FPA). Carbon credits are useful
to bolstering project finances but banks
are generally critical of projects requiring
carbon sales for IRR. Several donor funding
opportunities are also available but a
project must be well conceived and detailed
development underway prior to success from
such financial sectors.
Job creation is a significant plus with AD
projects. To provide a ‘clean fuel’ to the
AD plant, food wastes (for example) are to
be separated by hand at source (shopping
centres, restaurants and others). SLR’s
current estimates in South Africa are that
approximately four to six permanent jobs are
created per tonne of waste provided to the
AD plant.
Thermal EfW bankability: Financially viable
mass burn EfW plants are usually large
centralised plants with CAPEX costs in excess
of R1 billion. Financial viability for EfW plants
can be demonstrated where the financials
employ an electrical sales tariff in line with
current Eskom and municipal charges, a
reasonable gate-fee and possible bolstering
with carbon credits, and donor funding. The
latter donor funding is generally accepted by
banks and is arguably the most opportune
catalyst to the financial viability of EfW plants
in South Africa. Recently in South Africa,
commercial organisations are considering
the viability of smaller-scale (<1.0 tph)
decentralised EfW plants, where gasification
and pyrolysis technologies can economically
come into play. Developmental costs for EfW
plants by and large involve:
• a FEED study (Front End Engineering
Design)
• project feasibility studies
• environmental planning and permitting
costs
• detailed emissions studies.
Similar to AD selection, the most important
criterion for technology selection is the
scalability of the plant and the scale of
operations. Additionally, feedstock preparation
requirements and flexibility in potential
feedstock variability are considered.

MINE WATER BALANCE
Engineers and investors alike are increasing their risk margins to incorporate the risk of climate change, where the potential change in rainfall patterns and events could be more threatening to project viability and sustainability. by Peter Shepherd*
Air pollution /CDM
Project risk rising with climate change uncertainties
As part of a pre-feasibility study for a
mine (a new mine or an existing mine
that is being expanded) there is a
risk portion included in the capital portion of
the feasibility study to encompass areas that
may need additional capital. Typical capital
risk portions in a prefeasibility study could
be the inclusion of a liner under a tailings
dam because of the unknown potential for
seepage under the tailings dam. All aspects of
planning and implementation must be taken
into account when assessing the financial
risk faced by any new mining operation or
expansion project, and climate change has
definitely been introducing more uncertainty
into future scenarios for these projects.
In South Africa, for instance, climate change could make the eastern parts of the country significantly wetter and
western regions drier, according to studies by researchers TG Lumsden and RE Shulze. They predict that in the eastern areas of the country, mines will experience a disproportionate increase in the amount of water that is spilled into the environment. On the other hand, mines in the western parts will need to manage their water supply with greater care.Using the Lumsden and Shulze research, SRK scientists, Phillip Hull and
Hediyih Ghassai, predicted that a 40% increase in rainfall could more than double the amount of contaminated water spilled by a mine into the environment.
The risk of spillage is directly related to the rainfall expectations for a particular area – and not just the amount of rain, but also the way in which the rain falls. Looking into the future, we are anticipating that the intensity of precipitation in a particular area could be more intense meaning that the same amount of rainfall
could fall in a much shorter period. This has implications for the amount of run-off that a mine site will need to deal with and could mean that additional stormwater controls that are much bigger than under present conditions will need to be constructed and additional equipment may be needed to manage the silt that flows from the mine site.
BaselineGreenfield projects need data to be gathered over the entire year to incorporate the dry and wet seasons, combined with historical rainfall data, to establish a baseline for how water issues are best incorporated into the design of a new operation. Monitoring systems are put in place to gather primary data over a 12-month period on precipitation, run-off and water quality. The historical data from the various government departments are also collected but usually these records from national water authorities are collected on a regional scale and the local site hydrology and meteology data needs to be collected at the site.
This baseline gives engineers the parameters in which to optimise their designs and make cost-effective proposals to clients about how to manage the various elements of risk. The data collection is relatively small from a hydrological perspective. Clearly, a baseline cannot give a risk-free prediction for what conditions need to be accommodated by site infrastructure, so a risk margin is then built into the future scenarios that need to be considered.
A risk workshop – held with the client – is a good forum for considering the cost implications of the various risk scenarios, and for deciding on strategies that are

Air pollution /CDM
cost-effective while adequately mitigating against any mission-critical failures.
The new unknownThis is where climate change has emerged as a factor that consulting engineers need to flag to clients as a further uncertainty. Given the evidence of changing weather patterns in various parts of the world, we can no longer assume that our baseline reflects a static picture that can be relied upon in the short- to medium-term future.
So we need to ask questions like: • What if rainfall intensity increases –
how much bigger will we need to build our stormwater controls?
• What if rainfall increases – how much bigger will we need to build our dirty water containment facilities?
• Will the yield from our water storage facilities still be sufficient to adequately supply the mine with water if there is a significantly drier period of rainfall than the historical dataset?
• Will an increase in rainfall increase the excess water that the mines will need to deal with?
The risks posed by these uncertainties might be operational, environmental or reputational, but they all affect the sustainability of the operation and therefore need careful consideration in advance of final design and imple-mentation decisions. At an operational level, a relatively small shift in the intensity and length of a downpour could lead to the flooding of an open pit, leading to cessation of mining operations and possible damage to in-pit facilities. If such a precipitation event can be built into the risk profile, however, then the appropriate design could accommodate this.
A relatively simple up-front design solution such as increased pipe diameter and pump capacity could be proposed with only minor impact on the capital expenditure incurred. The solution, even if more expensive, would certainly be substantially less costly than trying to introduce these specifications on an already-operating site experiencing extraordinary precipitation levels.
Regulating impactThere is hardly a country that has not tightened up its environmental laws in recent years, and mines have in many instances been pioneers in mitigating and avoiding environmental impact. The area
remains a significant risk for developers and managers, however, especially as climate change threatens to ‘move the goalposts’. In areas that are likely to experience less rainfall going forward, better reuse strategies will be required to manage the on-mine water balance. Continued improvement is required in the design and implementation of ways to keep dirty water within the mine boundary, and to limit the amount of clean water that mines procure from municipal or other sources. In South
Africa, the Water Act of 1998 has also forced mines to focus on floodlines on or near their properties; in the context of climate change, mines also need to proactively anticipate more frequent flood occurrences, which may even exceed previous record levels.
Reputational riskAny negative impact on surrounding communities is a risk to the reputation of the owners and financiers of a project. Flooding of Return Water Dams is a particular risk in this regard; here in South Africa, it is strictly enforced by the Department of Water Affairs Dam Safety Office. A new dam safety regulation has been promulgated in South Africa that now requires dams to be classified in terms of the size as well as its hazard potential. From a mining perspective all polluted water dams will need to apply for the services of an Approved Professional Person to do the design as well as apply for a licence. Many of the documents that the regulation requires are being prepared by the mines such as design reports (details of dam, hydrology, structural, hydraulic components) plus a flood handling procedure, engineering drawings (locality, layout sections) and dam safety aspects (if inundation of development may occur). The impact of hydrology on the dams is an important aspect for the design of these dams.
Increased daytime temperatures associated with climate change also bring their own risks to the efficient running of a mine and its plant. As mines
pursue water-conserving technologies that rely on reuse of stored water, there may be a higher risk of treatment plants having to deal with more polluted water due to the evaporation increasing the salinity in the water. So the overall impact of climate change on the water risks associated with greenfields and brownfields mining projects is undoubtedly adding more risk – and hence more cost – to the planning and building of new mines and their infrastructure.
But equally, the science behind climate change is improving continuously as we make more detailed studies of shifting weather patterns and their impacts around the world. These are all feeding into a growing body of knowledge that will gradually erode some of the uncertainties we currently face in the management of projects’ water risk. The data, of course, will still need to be modelled for the purposes of prediction, and there will always be a variety of modelling methodologies and results to be considered. But the joint endeavours of on-site professionals, contracted consulting engineers, researchers, academics and other stakeholders will keep us at the cutting edge of technologies to manage water in ways that our enterprises and our environment demand.

We live in an era where it is
generally accepted that future
generations may never lay eyes
on many of the species we have taken for
granted in our lifetime. This is why Food &
Trees for Africa’s founder, Jeunesse Park,
gathered a group of concerned individuals
in 1990 to address climate change, with
the realisation that the real environmental
crisis in this country centred on people.
Twenty-two years later, Food & Trees for
Africa (FTFA) sees the effects of climate
change impacting on more people across
the globe. The importance of education and
awareness about environmental issues could
not be more needed and this underpins all
of FTFA’s work. This green work now includes
the distribution of over 4.1 million trees,
the facilitation of thousands of organic food
gardens for the poor, the world-first verified
bamboo carbon offset programme, organic
farm support and training, and the initiation
of the first carbon calculator and mobile site
calculator in South Africa.
World Forestry Day has been celebrated for
over 40 years now – the concept originating
from the 23rd General Assembly of the
European Confederation of Agriculture in
1971. That same year, the United Nations
Food and Agriculture Organisation gave
support to the idea, hoping that it would
raise awareness of the importance of
forests. World Forestry Day stands as
an annual reminder of the importance of
forests and the numerous benefits we gain
from them.“In a world where people know
more yet understand less about natural
resource extraction and what we are doing
to ourselves by destroying the lungs of the
planet, it is unfortunate World Forestry Day
does not happen everyday,” says Lucky
Xaba, FTFA ecopreneur.
African forestsAccording to a paper by Barbara Unmüßig
and Stefan Cramer¹ on climate change in
Africa, African ecosystems and people will be
the major victims of global climate change.
The small amount of carbon dioxide (CO2)
emissions from technical sources contrasts
with the larger net emissions of CO2, which
result from rapid deforestation. This is true
for the twelve densely wooded countries
of equatorial Africa whose corresponding
annual (2005) emissions are estimated at
approximately 1.1 billion tonnes (FAO 2007;
UNDP 2007). The stock of CO2 stored by
African forests amounts to approximately
60 billion tonnes, about as much as that
of all OECD (Organisation for Economic
Cooperation and Development) countries
put together, including densely wooded
members such as Russia and the United
States of America. A higher quantity of
CO2 is only stored in the forests of the
Amazon Basin. The biomass stored in the
forests is decreasing – and therefore the
emission of CO2 from forests is increasing
– a disastrous development for both Africa
and the global climate. Rain forests are
on the one hand a huge storehouse for
atmospheric carbon, while on the other hand
deforestation sets free huge quantities of
CO2. With proper protection of the African
forests, the continent’s emissions would
be compensated for many times over and,
an important contribution to the fixation of
carbon in forests at the global level would
be made.
As deforestation continues at an alarming
rate, FTFA hopes that society will learn
from the mistakes of the past, and future
generations will get to see what our great
forests look like in real life and not just as
pictures in a book. The United Nations’ data
shows that half of the world’s forests were
destroyed in the last century.

Hazardous waste
Environmentally conscious building
contractors in South Africa can now
enjoy the full benefits of PVC piping
products, following the announcement by
the Green Building Council of South Africa
(GBCSA) in October 2011 that it will remove
the MAT-7 PVC minimisation clause from
its Green Star rating system. The GBCSA
developed the Green Star SA rating tool to
provide the local property industry with an
objective measurement for green buildings,
and to recognise and reward environmental
leadership in the industry. A green building
rating tool sets standards and benchmarks
for green building and enables an objective
assessment to be made as to how ‘green’
a building is. The rating system sets out
a menu of all the green measures that
can be incorporated into a building to
make it green. Points are awarded to a
building according to which measures have
been incorporated and, after appropriate
weighting, a total score is arrived at, which
determines the rating.
The council initially introduced the
clause in 2007 to minimise the use
of PVC products in buildings, due to
environmental concerns regarding the
formulation, manufacturing process and end-
of-life disposal of PVC products. Following
negotiations with the South African Vinyls
Association (SAVA), the GBCSA agreed to
adopt recommendations to remove the
MAT-7 PVC minimisation credit in its rating
system, provided that PVC manufacturers
adhere to best practice conditions.
Initially, a PVC expert reference panel
(ERP) was formed, which acted as an
advisory group to the GBCSA and assisted
with technical matters on domestic and
international best environmental practice
initiatives related to the manufacture, use
and end-of-life of PVC building products.
In particular, the panel advised on the
applicability of the revised Australian Green
Star PVC credit to the South African context.
Commitment from SAVAThe 24 members of SAVA have committed
themselves to the responsible and
sustainable use of
PVC with the signing
of the industry’s
Product Stewardship
Programme (PSP) at
the association’s AGM
earlier this year. “Our
Product Stewardship
Programme is a
series of achievable
commitments that address the industry’s
environmental issues and forms the
cornerstones of the association’s focus and
activities,” explains Delanie Bezuidenhout,
CEO of SAVA. “PVC has, in recent years,
received a bad rap from environmentalists,
the public and the media who are, in many
cases, unaware of the hard work being done
behind the scenes to ensure that vinyls are
environmentally safe and sustainable.”
The association therefore aims to raise
awareness of the good qualities of PVC by
assisting its members, relevant authorities
and experts to understand, characterise
and address product stewardship issues
associated with the life cycle of PVC products.
SAVA is ideally positioned within the local
plastics industry and has representation
on the Recovery Action Group (RAG), the
Packaging Council of South Africa (PACSA)
and the Plastics SA Sustainability Council.
Pipe industry welcomes changeDPI Plastics product manager for pressure
pipe systems, Renier Snyman, says that
the MAT-7 minimisation clause impacted
negatively on plastics sales, as contractors
and architects would avoid the use of
PVC pipes in order to obtain a four or five
star green rating for their building. “In the
past, any projects that used PVC would be
penalised, significantly affecting their rating
in an industry that is becoming increasingly
environment-conscious,” he explains.
GBCSA CEO, Brian Wilkinson, adds:
“In late 2011, the GBCSA completed a
comprehensive credit review process for the
Mat-7 PVC minimisation credit, which is one
out of 69 total credits in the Green Star SA
green building rating system. The GBCSA
Technical Steering Committee resolved to
withdraw the credit after considering the
outcomes of the credit review, which involved
stakeholder engagement through a PVC
Expert Reference Panel and precedents
set by other green building councils
surrounding the treatment of PVC in green
building rating tools.”
Snyman points out that the removal of
the clause now means that the use of PVC
products has a neutral impact on the green
star rating of a building in South Africa. The
neutral rating does, however, only apply to
PVC manufacturers that meet best practice
conditions based on the manufacture and
recycling of the product. Due to its light
weight, high strength, low reactivity and
corrosion resistance, Snyman notes that PVC
is the material best-suited for piping.
After the local PVC industry suffered a huge knock in sales following its bad environmental rap, the Green Building Council of South Africa has offi cially declared that the use of PVC products in eco-friendly projects will no longer be penalised.

HAZARDOUS CHEMICAL SUBSTANCES AND DISEASES
Statistics presented by the Department of Labour at the end of 2011 indicated that hazardous chemical substances are the most common cause of occupational diseases and chemical related incidents in the chemical and metallurgical industries.
Hazardous waste
Understanding environmental health risks in the workplace
Environmental, occupational health,
hygiene and safety involve dealing
with environmental, health and safety
hazards and risk within the micro (work
environment) and macro environments
(communities and external environments)
by applying risk management concepts.
These are regulated in terms of the
National Environmental Management
Act, the Environmental Conservation
Act, the Hazardous Substances Act, the
Health Act, the Occupational Health and
Safety Act 85 of 1993 and incorporated
regulations and standards such as
SANS. Non-compliance to these statutory
requirements can lead to environmental
pollution, accidents, incidents, disabling
injuries and the prevalence of occupational
diseases, which can cost the country
billions in compensation claims a year.
Non-compliance with legislation may
result in prohibition notices (stop work),
contravention notices, penalties and fines.
Health and safety in the workplaceIncreased global awareness of hygiene
in the workplace prompted the formation
of the human impact environmental
testing specialist company, Specialised
Environmental Services. The company is one
of 29 fully accredited Approved Inspectorate
Authority (AIA) companies in Southern Africa,
focusing on people and the impact of the
environment on their health and safety
by ensuring a comprehensive solution for
ensuring employees and clients are exposed
to a healthy and safe environment, compliant
with the Occupational Health and Safety Act
No 85 of 1993, says managing director, Dr
Dave Bernhardi.
Bernhardi says today occupational health and
safety is not only on noise and lights, but the
environment itself. “This is evidenced by the
return of tuberculosis and the advent of swine
and avian flu, as well as diseases such as
legionella, which many have heard about but
don’t understand the implications of. Testing
for hazardous biological agents through swab,
RéSource May 2012 – 47
Hazardous waste
air, water sampling and hard surface testing is
becoming important,” he says. The company
also provides an integrated health risk
assessment service for health risks associated
with the exposure to hazardous chemical
substances (HCSs). This assessment forms an
integral part of any employer’s human resource
protection strategy and drives operational
readiness to ensure the health, safety and
well-being of employees.
The risk assessment processIn many companies, the responsibilities for
Environmental Hygiene and Occupational
Health and Safety are segmented, resulting in
a lack of communication and therefore poor
hygiene and safety standards. Specialised
Environmental Services enters into strategic
partnerships with its clients to implement
project management and support at their
sites. Full risk assessments are conducted
by occupational hygienists and environmental
practitioners, and services include: hard
surface swabs, air quality monitoring
(ventilation and gas), water sampling, sound
testing, light testing, solutions consulting,
staff training and education, and the
management of the testing and solution
process. State-of-the- art equipment is used
to conduct assessments and all procedures
undertaken are done as per standard
legislation.
The first logical step is hazard identification
whereby hazards and risks are identified
and anticipated. Secondly, the risks need to
be evaluated by scientifically quantifying the
occupational and environmental hazards and
risks; and thirdly, to decide on the tolerability
of the risks by applying a risk rating, decide
on the effectiveness of current control
measures in place, and also decide on the
appropriate controls for the risk.
On implementation of the mentioned
controls, their efficacy must be monitored
regularly by conducting control measure
efficacy assessments and routine
occupational hygiene monitoring as prescribed
by methods, standards and legislation.
Findings are documented and a report with
recommendations and corrective actions is
presented by the action committee. These
can highlight the need for increased health
and safety in the work environment, to comply
with hygiene standards or to measure up to
ISO requirements. Training and education
ensures knowledge transfer and buy-in
from all employees, from shop-floor level to
senior management.
The ongoing working relationship offers a
cost effective alternative to annual hygiene
surveys and ensures that regular re-evaluation
and monitoring of the corrective procedures
take place. “Companies will be put under
increasing pressure to present accredited
test results when confronted by charges from
consumers, who have becoming increasingly
aware of their rights since the introduction
of the Consumer Protection Act,” Bernhardi
explains. “The Department of Labour is
also aggressively pushing to ensure hygiene
standards are adhered to. Although certain
commercial and industrial sectors will be
under the spotlight, any company employing
staff and providing services to clients or
consumers is liable to maintain health and
safety standards.”

GLOBAL TRENDS, LNG AND HIGH OIL PRICES
China’s economy eclipsing Japan as the world’s second largest economy has long-lasting impact on global energy production, consumption and prices. These macro changes are not fl eeting but structural, shifting the cyclical rhythm of the global oil and gas market. by Adi Karev*
Hazardous waste
Oil and gas – a balancing act
It used to be sufficient to view global
oil and gas trends in the typical cyclical
rhythms the industry moves in. But,
in the last 5-10 years, significant macro
changes caused spikes in the usual metrics
we evaluate, that is production, consumption
and price. For example, China’s economy
eclipsing Japan as the world’s second largest
economy has long-lasting impact on global
energy production, consumption and prices.
The shift that is occurring is a new balancing
of the geographic flow of petroleum supply
and demand, a balancing of fuel types, and of
the types of players involved. To explain this
balancing trend, here are some examples:
• resurgence of the global LNG trade
• development of unconventional natural gas
• sustainment of high crude prices driving
riskier energy and petroleum (E&P)
investments
• the rising cost of doing business.
Global LNG developments In the early 2000s, about 10 countries
exported liquefied natural gas (LNG), trade
was based on long-term sales agreements
and flowed from producers in South-east
Asia and the Middle East to consumers in
East Asia and Europe. Today LNG is slightly
looking more like a globally traded commodity
with greater spot trading (prices ranging
from $US4 to $US17 (R31.50-R134.30)
per MBTU), new exporters in Latin America
and West Africa, and new importers such as
China and India. In five more years, there
will be more exporters in North America,
Eastern Mediterranean, and East Africa.
And by 2035, LNG could account for 50%
of the international gas trade, increasing
from 26% in 2002. The emergence of new
LNG exporters and importers changes the
dynamic of energy geopolitics. A potential
scenario of Europe buying gas from Israel’s
Leviathan field or from the United States Gulf
Coast, and less from Russia, could change
the supply security in the region. The growth
of LNG also signals a shift in fuel mix as
countries such as the United States, China,
Australia and Japan see a future more reliant
on natural gas than coal in the United States
and China, and nuclear in Japan.
Currently, the tight supply of LNG and high
demand from Japan in the aftermath of
the Fukushima disaster has created a wide
price spread. In 2011, Japan paid as high
as $US18 per MBTU for spot cargoes of
LNG to meet domestic demand, while North
America gas prices remained at around
$US4 per MBTU. According to economics,
the law-of-one-price means global LNG prices
will equalise in the long-term. Though, in the
near-future, we may continue to see a high
price spread considering that ship orders will
be fulfilled around 2015, final investment
decisions for major LNG projects in Australia
will also be made by this time and, post-
2015, we may see significant LNG volumes
exported from North America.
The upward trend of LNG prices creates
opportunities in further developing the
global market. National Oil Companies
(NOCs) and major international players
are forming partnerships in LNG projects,
which include E&P and downstream
infrastructure development. Chinese NOCs
offer much needed cash for expensive
projects, especially in Australia, and in
exchange the NOCs secure future supply
and can potentially play the price arbitrage
opportunity. The price spread, diversified
market of producers and consumers, and
infrastructure development creates conditions
for players to exploit price differences and
divert LNG cargoes to higher-paying buyers.
This development is notable because it
drives innovation in contract clauses, trading
models, and price information sharing, which
are the seeds to grow LNG into a globally
traded commodity.
The global LNG market outlook appears
to be bright, which is good news for sub-
Saharan Africa. Nigeria as a top producer
of LNG will soon be joined by Angola, and
possibly Mozambique and Tanzania, bringing
Angola LNG is on track to deliver its first liquified natural gas exports in 2012

much-needed production capacity to the market. There are
significant challenges throughout the LNG project lifecycle, first
of which is developing natural gas fields, especially offshore. The
capital intensity of liquefaction infrastructure is compounded by
costs related to labour and regulatory processes.
Unconventional gas Part of the LNG equation is unconventional gas. Shale gas and
coal-bed methane resources make it possible for the United States
and Australia, respectively, to be top LNG exporters by 2020. The
theme of rebalancing is clearly seen in the case of the United
States where the shale gas potential could reverse the country’s
trade flow and make it a net exporter. Indeed, plans have been
approved in the United States Gulf Coast to retrofit LNG import
facilities into exporting ones.
The trend of unconventional gas development is a global one.
Countries that seemed to be destined as net importers of energy
face the prospect of self-sufficiency. Shale gas exploration projects
are occurring in China, India, Poland, Argentina, Germany, and
South Africa. The major impediments to shale gas development
include cost, labour, drilling complexities, and above all, the
controversy surrounding fracking, which has been felt in South
Africa given the government moratorium.
Rising cost of doing business Although capital expenditures and petroleum discoveries are on
the rise, so too are operating costs. One of the main drivers of
increased Opex is higher wages, and this could be a long-term
problem with a perceived shortage of skilled labour. In a recent
survey of petroleum executives conducted by The Economist,
shortage of skilled labour was listed as the second major barrier
to growth. The labour factor is an acute challenge in Canada and
Australia where unconventional exploration is more labour-intensive,
the shortage of skilled workers drives up wage rates, and locations
are remote requiring additional costs. For Australia, the labour
rates are compounded by rising construction costs causing LNG
projects to be delayed and over budget. Ultimately these costs
drive up the price of LNG and may impact the competitiveness of
Australian LNG once other production comes online.
In the same survey, 82% of the petroleum executives agreed
that government regulation has become more important. Increased
regulation also impacts operating costs. Related to government
regulation is the revision of petroleum fiscal policies. High crude
prices amid slumped GDP growth are prompting governments to
re-examine profit-sharing agreements, and governments with new
petroleum sectors are carefully crafting their petroleum policies.
Governments revising such policies struggle to balance increasing
revenue with encouraging investment. Using Brazil as an example,
the government last year amended production-sharing agreements
to mandate a 30% stake for Petrobras on strategic blocks and an
oil outtake for the government. The oil and gas industry in sub-
Saharan Africa, with its long petroleum history and bright future in
offshore and unconventional resources, stands squarely in these
balancing dynamics. Understanding this balancing trend offers
a framework to uncover potential risks, and opportunities for
investments, partnerships and cooperation.

The Responsible Packaging Management Association of Southern Africa celebrates ten years of success within the hazardous waste industry. RéSource chats to the association’s executive director and president, Liz Anderson, on its inception and what the next 10 years might hold.
RPMASA feature
A decade of responsible packaging
Q. What is the core function of the RPMASA? A. To be the leading authority in Southern Africa on industrial and chemical packaging, provide information and training to assist organisations with knowledge and tools to be legally compliant, and implement best global practices for sustainable use of resources, protection of people and the environment. The Responsible Packaging Management Association of Southern Africa (RPMASA) is a Section 21 and registered non-profit organisation for everyone involved in the life cycle of industrial and chemical packaging.
Q. When was the RPMASA established and what reason(s) were behind this formation?A. The RPMASA was started by a group of proactive reconditioners who approached me in late 2001 to establish an independent, professional, value chain body to bring together packaging manufacturers, users and reconditioners, to improve cooperation and recovery for
reuse and compliance. It was formally launched in May 2002 as RCMASA – Responsible Container Management Association of Southern Africa to replace the former SADRA – South Africa Drum Re-conditioners – which was formed and run by reconditioners in 1996 but became defunct in 1999. The strategic objectives of the newly formed RCMASA were: • to establish good relations with
international organisations • to adopt the international principles of
responsible packaging management and work with international organisations on best practice and regulations
• to establish codes of practice and national standards
• to establish a national audit and registration scheme to uplift standards and level the playing fields
• to establish training and regional workshops to inform and educate members, users and local authorities
• to work with government on packaging, transport, environmental and waste legislation
• to establish a national collection system for higher recovery to clean for sustainable reuse. Excellent international relations were
quickly established, with the other objectives in place by May 2004.
Q. Who were the founding members? A. The founder members include Adrian Goods, Alan Firmani, Lewis Page-Lee, George Subramoney, Liz Anderson, Chocky Moodley and Derek Cheesman, who is chairman. Other founding members are Ishmael Kunene, Bhizini Kekana, Joseph Malatjiall, Bibi Avivi, Arnand Moodley and Gal Agoustatas.
Q. What have been the RPMASA’s top five achievements?1. Acceptance by international packaging
bodies and assistance to develop the SANS 10406 Standard, Audit Protocol, Training, Southern African Auditor and Training Certification Association Auditor Registration Scheme and Reconditioner Registration Scheme.
2. Approval of application to the United Nations (UN) Committee of Experts for Transport of Dangerous Goods and the Globally Harmonised System (GHS), participation in Geneva meetings and providing information and a wealth of International Expert contacts and network to local Industry.
3. Partnering with eThekwini and working with the street traders for the City Safe drum Policy and provision of new safe “Happy drums” for the poor.
4. RPMASA 2009 and 2011 International Conferences and International Maritime Dangerous Goods and the UN Institute for Training and Research GHS training – bringing knowledge to our country. Looking to the 2013 Conference – we are in planning process with the South African Maritime Safety Authority, and invite companies to contact us to partner, sponsor and exhibit.
5. Providing members the opportunity to participate in Cleaner Production programmes with the National Cleaner Production Centre to improve their operations, save resources and money.
Q. With regard to hazardous packaging, what has been the single worst experience that you have encountered?A. Lack of support and indifference to stewardship and record keeping, especially by large industry for their used packaging resulting in dumping

and poisoning of children through contaminated drums containing heavy residues being sold to traders:• Durban 1997 – 36 children were
hospitalised after using a white chalky residue from a drum (identified as organophosphate), which they licked to chalk the pavement to play hopscotch – two children died.
• Soweto 2004 – 3 children who drank water from a 25 ℓ drum died a painful death from an acrid chemical residue.Also, unacceptable reconditioner sites
(and practices) used and condoned by large business as well as various spills and accidents caused by use of incorrect or non UN certified packaging for chemicals.
Q. What awareness campaigns are currently being run by the RPMASA?A. Safe Happy drums to improve recovery, reduce pollution and protect poor families and communities.• Safe and proper methods for drum
emptying to reduce waste, save money and reduce burden to reconditioners and recyclers – posters in partnership with KwaZulu-Natal Department of Agriculture, Environmental Affairs and Rural Development.
• Duty of Care – EPR Stewardship by companies to record where their waste packaging goes to and ensure safe collection.
Q. Has the RPMASA been involved with government on any projects? A. Yes, at national, provincial and local level:• Happy drum – eThekwini since 2005• Department of Transport – packaging
and transport standards and regulations since 2002
• Departments of environment, health and agriculture – on safe handling of correct specification packaging to reduce risks to people and environmental pollution
• Department of Environment – Waste Act and regulations, as well as request for Sector Integrated Waste Management Plan for industrial and chemical packaging
• Provincial departments – KwaZulu-Natal, Gauteng, Western Cape and Free State on environmental and waste minimisation and pollution prevention
• Department of Labour – safe handling
of chemicals and packaging and GHS of classification and labeling of chemicals and dangerous products for sale and use, that is, workplace and consumers
• Department of Trade and Industry – Environmental Goods and Services sector for the Industrial Policy Action Plan funding to assist members improve their business and job creation for service providers
• Consumer Protection Act and participation in National Standards and International Mirror Standards through the SABS
• International: UN Committee of Experts for Transportation of Dangerous Goods and GHS as well as input to work groups and through our sister organisations.
Q. Where do you see the association in the next ten years?A. Ideally looking back with satisfaction to see: • industry embracing Responsible
Packaging Management
• manufacturing and service companies compliant and implementing Duty of Care and EPR
• that all large packaging is accounted for and recovered for reuse or responsible recycle/use in a sustainable process.
In reality focusing on: • education – technical and regulatory
through participation in international and national committees
• assisting industry with packaging compliance, cleaner technologies, recovery, reuse and recycling of all packagings
• awareness raising and capacity building for communities and seeing the roll out of Responsible Packaging Management and Happy drum across South Africa, SADC and Africa as well as other developing countries
• audit and registration of organisations processing packaging for legal reuse with chemicals and liquids for safe transportation and reduced risks.

Environmental awareness in industry
has come a long way in the 10 years
that RPMASA (Responsible Packaging
Management Association of Southern Africa)
has been championing an environmentally-
friendly, safe and responsible approach to
packaging, manufacturing, transport and
disposal. It is towards this mission that the
National Cleaner Production Centre of South
Africa (NCPC-SA) has also been working for
the past decade.
Established in 2002, the NCPC-SA is a key
industrial sustainability programme of the
Department of Trade and Industry. It assists
industry in preventing waste at source and
in managing resources more efficiently along
the value delivery chain, utilising resource
efficiency and cleaner production (RECP)
methodologies and services.
RECP has become the preferred strategy
in reconciling the dual needs of economic
growth (through competitiveness) and
environmental protection (through waste
minimisation and efficient resource use).
Examples of RECP practices include
the following:
• improved housekeeping, especially around
material flows and maintenance practices
• process modification that may include
surface coatings and filtration
systems
• product redesign that may include
natural material use
• changes to technology that may
combine operations that reduce
wasteful practices
• input material substitution, for
example, substituting a water-based
ink for a solvent-based one in printing
processes
• on-site recycling, which could mean
the recovery of a nickel-plating
solution using an ion-exchange unit.
The NCPC-SA currently focuses on eight
key industrial sectors, which are: agro-
processing; clothing, textiles, footwear and
leather; chemicals, plastics fabrication,
cosmetics and pharmaceuticals; metals
fabrication, capital and transport equipment;
automotives; pulp and paper; tourism and
hospitality; and green industries, including
waste recycling/remanufacturing. Audits
undertaken in companies in these sectors
over two years yielded potential savings
opportunities of more than R78 million
in terms of energy, water and materials
usage (including waste minimisation), and
process improvements.
The NCPC-SA also manages the Industrial
Energy Efficiency Improvement project,
which was launched in 2010 in response
to the growing need to improve energy
efficiency in South Africa. The objective
is to involve companies to demonstrate
the impact of energy efficiency practices
as a means of increasing profitability.
In addition, the centre contributes to
capacity building in the country through
RECP and energy-related training events
presented by international experts, a
studentship programme and an SMME
accelerator programme.

PREVENTING WASTE, MANAGING RESOURCES
Cleaner production – more than just a noble idea“The NCPC-SA’s network of expertise is invaluable in demonstrating successes and assisting companies in exploring new technologies for waste prevention and reuse,” says Liz Anderson, executive director and president of the RPMASA.

Representatives from 24 countries,
OTIF, IAEA, ICAO, IMO and the
WHO together with 29 industry
associations attended the 40th United
Nations (UN) session on the transportation
of dangerous goods. Many corresponding
work groups will continue to work to firm
up formal documents for submission and
approval in the June or December 2012
sessions, so as to be included in the 18th
Orange Book revision due in 2013.
Eva Molnar, director, UN Economic
Commission (UNECE) transport division,
addressed committee delegates at the
December 2011 meetings, thanking all,
especially industry, for their continuing
efforts and inputs from experiences and
technology, to improving the safety in
transportation of dangerous goods (TDG)
across all modes.
Molnar informed members that budget
cuts would impact on the UNECE transport
division in the 2012/13 programme budget
but assured that the secretariat of TDG
and Globally Harmonised System (GHS)
sub-committees would not be affected due
the importance of their work, which has
a significant effect on the entire world’s
transport systems, particularly now with the
launch of the Decade of Road Safety: 2011
to 2020. She encouraged countries that are
not yet embracing the UN Model Regulations
to ensure implementation in their national
legislation and for members to promote
implementation. Molnar further encouraged
participation in the Decade of Road Safety
Programmes across the five main regions:
• Asia and the Pacific
• Africa
• Middle East
• North America
• Latin America and the Caribbean
Ed de Jong, chairman of the Explosive
Working Group, reported on inter-session
progress made and difficulties experienced
with some tests including oxidisers. He
advised that he was expecting a large
number of documents especially on tests,
desensitised explosives and explosion
risks of unstable substances for a parallel
explosives work group session in June 2012.
Applications from two new industry
associations were reviewed and accepted
as NGO (non-governmental organisation)
consultative members, namely, the
Dangerous Goods Trainers Association
(DGTA) and the Global Lighting Forum (GLF),
which addresses the growing concerns on
e-waste. The packaging industry was well
represented with several papers addressing
issues such as marking of manufacture
dates on plastic packaging, preconditioning of
plastic packaging and IBCs for compatibility to
vibration tests, GHS classification of corrosion
sensitivity, and regulations for the transport of
uncleaned waste packaging which contained
dangerous goods – all of which could have far
reaching impacts for the packaging industry.
The Responsible Packaging Management
Association of Southern Africa (RPMASA) is
participating in local working groups for the
above, as well as addressing other issues of
importance within the packaging industry, and
all input is welcome.
Other serious concerns arising at the
meetings included:
• harmonisation of transport classification
criteria with GHS classification criteria for
substances and mixtures corrosive to skin
• IBC packaging instruction requirements for
solids that may become liquid
• packaging with capacities exceeding 450 ℓ• large salvage packaging
• proposal to amend and extend the
transitional period for UN portable tanks
• electronic data interchange
• decade of Action for Road Safety.
Items of general interest included:
• report back from lithium batteries working
group, which included proposals on the
transportation of damaged or defective
goods, and the transportation of waste
such as used batteries
• Lithium battery markings
• fumigation warning mark and coolant/
conditioning unit warning mark to prevent
asphyxiation on opening of containers
• light bulbs containing small quantities of
dangerous substances
• classification and packing of asbestos
• ‘Torch’ cigarette lighters that contain
lithium batteries.
Until the regulations and laws are strictly adhered to, packaging and transport of dangerous goods will continue to rank as important agendas on the global ‘safety list’.

SHARPS DISPOSAL PRACTICES
Medical waste
Case study of diabetic patients using insulinWentworth Hospital is a district-level hospital in Durban that sees almost 12 000 outpatients per month. The hospital pharmacy dispenses about 5 000 insulin pensets monthly, each with a needle, to patients. There is no record of any sharps being returned to the hospital for disposal. by D Govender and A Ross
Insulin-dependent diabetic patients are
not educated on safe sharps disposal
methods, leading to unsafe disposal
of needles. Appropriate education on the
correct disposal of sharps should be an
integral part of their diabetic counseling.
Patients should be advised to either discard
sharps into puncture-resistant containers
placed into their household refuse, or return
them in secure containers for disposal by
the dispensing institutions. Patients should
also be educated regarding health risks
associated with used needles.
We investigated current methods of sharps
disposal by diabetic patients attending
Wentworth Hospital’s (WWH) outpatient
department (OPD), to compare these
practices with the education received by
patients about correct sharps disposal, and
to make recommendations regarding the safe
disposal of sharps by diabetic patients.
MethodsThe study at WWH included insulin-dependent
diabetic patients over the age of 18 attending
WWH OPD who consented to participate. In
consultation with a biostatistician, a sample
of 132 diabetic patients using insulin was
chosen. The sample size was based on the
assumption that the population prevalence of
incorrect needle disposal was 90% and was
calculated to give a precision level of 5%. To
ensure representation of all the racial groups
treated at WWH, the sample was stratified
into 45 Indian, 44 Black, 36 Coloured and
7 White patients. The study took place from
October to December 2010. Questionnaires
on current practices regarding insulin needle
disposal and on education received regarding
sharps disposal were administered to each
participant by the principal investigator. Data
was entered onto an Excel spreadsheet and
the SPSS computer software package used
to analyse the data. Factors associated
with correct disposal methods were
analysed using Pearson’s chi-square tests.
A p-value of <0.05 was considered to be
statistically significant.
ResultsThe ages of the study population ranged from
18 to 86 years; most had type 2 diabetes;
29% were male and 71% female; 4 (3%)
were younger than 25 years, 3 (2.2%) were
between 25 and 39 years old, 64 (48%)
were between 40 and 59 years old, and
62 (46.2%) were over 60 years old. Nine
patients had received no formal education;
31 had only attended primary school, 84
attended secondary school, and 8 had
tertiary education.
Each month, 850 needles were generated
by the 132 patients. Needles were reused
2 to 20 times by patients; 117 (88%)
patients disposed of used needles directly
into their household rubbish bins, 8 (6%)
flushed used needles down the toilet into
the sewage system and 4 (3%) used other
methods such as burying the needles. Only
3 (2.2%) patients returned their needles in
puncture-resistant containers to the hospital
for disposal. No associations were found
between race, gender, education levels and
correct disposal of used sharps. Forty-six
(35%) patients were aware of the potential
health risks associated with injury caused by
the incorrect disposal of used needles.
Of the participants, 91% (120/132) had
received diabetic education and counseling
regarding insulin use, storage and adminis-
tration; 68% (89) rated the diabetic education
as good, 22.7% rated it average and 9.7%
as poor. Despite the positive response to
the education provided on use and storage
of insulin, only 5 (3.8%) patients stated that
they had received education and counseling
regarding correct methods of sharps disposal.
All three patients who were correctly disposing
of their needles had been educated about
how to do so. There was a highly significant
association between education received by
patients and correct needle disposal methods
(p<0.001). Of the five who were educated
in disposal, 60% correctly disposed of the
needles whereas, of the 127 who were not
educated in disposal, none correctly disposed
of the needles.
DiscussionThe race groups recruited for the study are
representative of the patient population with
diabetes seen at WWH. The data showed
that over 97% of the study population
discarded their sharps inappropriately.
No recent studies were found on safe
disposal of sharps by diabetic patients.
However, our findings are consistent with
studies in the early 1990s in Europe and the
United States of America, highlighting the
fact that needle disposal is a global problem
in the developed and developing world.

Medical waste
The large number of patients who dispose
of their needles incorrectly is of concern.
The National Environmental Management
Act of 1998 states that the duty of care
principle requires the generator of hazardous
waste, under all circumstances, to carry
the responsibility of the ultimate fate of
the generated waste. Patients, healthcare
workers or healthcare facilities could be
liable for costs associated with treating
garbage collectors who can prove that they
were infected from contaminated needles.
This serious issue requires urgent attention
from health professionals, who have a
responsibility to provide information to
patients about safe disposal of needles. It is
disappointing to note that since 2009, when
disposal of needles and other hazardous
material was identified as a serious issue at
the Health Care Summit, more emphasis has
not been placed on safe needle disposal.
Despite much work on needle-free products
for the administration of insulin, progress
has been slow and inconsistent, and no
significant needle-free alternative method
of insulin administration is available. As
needles will continue to be part of diabetic
care by all patients requiring insulin for
some time to come in South Africa and other
countries, their safe disposal must therefore
form an integral part of diabetic education.
Although this study’s numbers are small
and the results must be treated with caution,
they suggest that appropriate education
and knowledge on sharps disposal is the
most important determining factor in correct
disposal methods.

Diabetes is conservatively estimated to occur in 4 million South Africans; all type 1 and up to 40% of type 2 diabetic patients require insulin therapy.
Used sharps are a biomedical hazard as incorrect disposal could lead to needle-stick injuries (NSIs), posing the risk of contracting HIV, hepatitis B or C, and other blood-borne diseases.
An individual not protected by prior hepatitis vaccination who sustains an NSI from a needle used by an individual testing positive for hepatitis B surface antigen has a 6 to 30% chance of infection by the virus.
Sharps disposal is a problem in South Africa because of accidental NSI to garbage removers or other persons handling domestic waste.
The 2009 Health Care Waste Summit recognised the problems with sharps disposal in South Africa. The safe disposal of needles and lancets used by insulin-dependent diabetic patients is not only a problem in South Africa; in 1989, 109 NSIs were formally reported by garbage collectors in the Atlanta (United States) metropolitan area, and other studies in Atlanta and European countries have highlighted the problem of incorrect sharps disposal practices by patients at home.

IMPROVING ACCESS TO CLEAN WATER
South Africa is one of the many countries faced with the serious issues of water scarcity and the high cost of potable water. Research has shown that by using rainwater tanks, the need for expensive systems such as recycled wastewater can be delayed.
Wastewater management
Two rainwater harvesting projects revealed
According to authorities and research
organisations in Australia, by using
rainwater tanks for non-potable
applications, the need for expensive
systems such as desalination and recycled
wastewater can be delayed. In leveraging
this, many developers and municipalities are
changing legislations and building codes to
require the installation of rainwater tanks for
toilet flushing, irrigation and laundry uses.
Rocla Southern Africa, in collaboration with
Rocla Australia, launched the Rocla ecoRain
and ecoRain plus water harvesting systems
in a bid to encourage rainwater harvesting,
retention and re-usage. According to Justin
Kretzmer, sales engineer at Rocla, South
Africa is one of the many countries today
faced with water problems, including the
high cost of potable water to consumers.
“In Australia there has been a shift towards
water sustainable cities and integrated
watercycle management. These systems aim
to conserve potable supply by implementing
the rainwater capture and re-use aspects of
water sensitive urban design,” he explains.
With South Africa facing sanitation and
water challenges, the ecoRain system, that
is designed to capture clean rainwater, which
is then stored underground for further use,
is a step in the right direction. As the source
and quality of any captured water cannot be
assured, this system is intended to deliver
stored rainwater for non-potable applications,
helping to save costs and address some
sanitation challenges, while conserving
potable water.
How the system works“The captured water is conveyed through
numerous roof gutter down-pipes to the
ecoRain filter, which removes all debris
and waste greater than 0.5 mm diameter
in particle size. Only clean water is then
transferred to the system’s concrete tank,
while coarse litter is continuously removed
from the filter and discharged through the
overflow to the stormwater drainage system,”
Kretzmer describes.
Since the tank is installed underground,
it will not take up valuable land and the
load-bearing capacity allows it to be located
almost anywhere on site. While common
rainwater harvesting systems are in plastic
form and traditionally placed above ground
exposing the tank to heat and sunlight, these
underground concrete tanks are an ideal
method of storing water, proving an almost
germ-free environment away from light and
heat. “Concrete cisterns are strong, durable,
last indefinitely and help to neutralise
rainwater,” he adds. The concrete tank
capacities range from 3 000 ℓ up to over
RéSource May 2012 – 59
Wastewater management
1 000 000ℓ, and the harvested water can
be used for everyday applications such as
toilets, laundry, car washing and irrigation.
The RAIN project In a bid to preserve every drop of water,
the Replenish Africa Initiative (RAIN) Water
for Schools, aims to improve access to
clean water for over 2 million Africans by
2015 through a $US30 million (R228.83
million) investment in programmes such
as the one at Homba Primary School in
Khayelitsha, Cape Town. Working together
with government, Coca-Cola South Africa is
providing schools in disadvantaged areas
across the country with basic water and
sanitation infrastructure such as working
toilets and urinals, taps with drinking water
in and around the school area, drainage
systems and new basins and taps.
The infrastructure upgrades implemented in
schools varies according to individual needs
as assessed by the Department of Basic
Education.“We started the RAIN Water for
Schools project in 2010, with nine schools
as our legacy project for the 2010 FIFA World
Cup,” says Sammy Mohlaoli, senior manager
of Community Affairs at Coca-Cola South
Africa. “Since then we have identified a total
of 100 schools in all nine provinces of the
country that are in dire need of basic water
and sanitation.”
The lack of running water presents an
obvious set of challenges, in particular,
health risks. The project is a three-year
initiative that will be funded and implemented
by The Coca-Cola Africa Foundation
working with a number of co-finance and
implementing partners, including the Global
Environment and Technical Foundation,
Re-Solve Consulting, the Mvula Trust and the
South African Department of Education.
In line with this year’s World Water Day
theme, which focused on water and food
security, and as part of the Homba Primary
RAIN Water for Schools project, rain water
is collected by the school and used to water
a vegetable garden, which is maintained
by women from the local community. The
produce grown in this garden is sold,
providing economic empowerment for
the women.

REDUCING YOUR TRUCK’S FOOTPRINT
With today’s increasing focus on waste footprint reduction, proper route optimisation provides a substantial opportunity for waste collection companies to reduce their footprint in kilometres travelled, fuel used, vehicle maintenance costs and labour cost. by Terry Daley* and Matthew McCarthy**
Waste equipment
Rebalancing residential collections
While normal city council terrain may be relatively flat, population densities can vary considerably
with satellite pockets of suburb shopping centre clusters, dispersed along main road arteries from rural fringes into denser city dwellings. Differing terrain divided by geographic features such as rivers, mountains, rail lines or main roads and the variable distance of run areas from depots to and from nearest disposal sites on different days of service means widely different sets of time and workload capacity go into the balancing mix for route optimisation. This case study shows how Townsville City Council, Australia, went about capturing bin lift data automatically for balancing and reducing travel and time across disparate population density areas and different waste streams.
Merging of council runsThis project started with the merging of two separate councils’ waste services into
one consolidated council, which resulted in the need to re-balance residential collection areas within days of service boundaries. There was no packaged software that we could find available at the time, so the resulting innovative approach was developed as an iterative method of applying available technology to assist with the computerised mapping analysis in a study of how travel, time and workload could be optimised and balanced across disparate population density areas and different waste streams using actual presentation (lifts) from onboard automated data capture.
This real-world review project involved the use of cadastral map data that served as a background for plotting the dots of where different residential services (bins) were located and then overlaying data from GPS devices that could automatically capture actual travel data and each bin-lift arm movement. This enabled review of actual travel time, distance and number of lifts (real presentation rates) against number of potential property services on the map. We were then able to project the likely travel time, collection (lifting) time and distance in these areas bound by
different trucks capacities and diversions to nearest disposal sites.
Project objectivesThe project in Townsville started with the following objectives:• to review and equalise existing
collection runs from the amalgamated councils
• to resolve the large disparity in the time vehicles are operating daily (some operators finishing early and some being paid overtime)
• to optimise small teams by geographic area under the control of a leading hand
• disruption to commercial and domestic collection days must be kept to a minimum
• incorporate capacity for growth in developing areas
• drivers and supervisors to be involved in design/testing process
• produce revised run areas in electronic and printed format.

major make-over. Too many council waste collection companies sit back and accept the timeworn path their drivers weave.
Planning relies on old driver road knowledge and out-dated yellow-marked wall-maps and the experience and intuition of depot managers, rather than on any empirical calculations or projections based on readily available hard data.
Manual planning approaches have been using figure eights (8s) or ever-diminishing circles or flower patterns for gated-property-estates under an iterative trial and error approach to gauge any impact on total kilometres travelled. Yet variable terrain factors can make this difficult.
Major express ways also act as geographic dividers with restricted access and egress points and city centre peak
traffic times add occasional traffic snarls as they slow travel times to parking-lot speeds after accidents hem in trapped trash transporters.
Geographic Information System (GIS) is a key enabling technology combined with new on-board, automated data gathering devices (GPS) for giving visibility to management on current travel times and distance.
Data required for route optimisationStart by gathering what you are doing now. A typical list of the data you will most likely need to pull together for a residential mapping route optimisation project is as follows:GIS geographical map data• street map centre lines and ability to
section these into cross streets• street map network and any road
section restrictions• speed limits, maximum weight
restrictions, one way sections, turn limitations
• time restrictions – noise restriction hours, school zones, traffic time restrictions
• house numbers alongside of street sections or cadastre property boundaries
• size of properties and property type for example parks, industrial estates, apartments, high rise buildings).
Ratepayer data• ratepayer addresses and property
classifications (these address records can be used with a lot number to cross-check for correct spelling and suburb classification and valid house number ranges against the mapping data)
• Townsville is a coastal city in Queensland (Australia) with a population of 170 000 residents, and has a major port for the export of mining materials as well as a large military air force defence base.
• Townsville Waste Services has a staff of 82 for covering waste collection, transport and disposal using 19 side lift vehicles, three overhead lift trucks, three rear-loaders and one hook-lift truck and there are two landfills servicing the area.
• There are approximately 18 000 wheelie bins, 12 000 waste bins and 6 000 recycling bins collected each day as well as some 200 bulk bins and 150 litter bins emptied per day.
• the number and type (size) of bins allocated to properties (either by property type or individually)
• special properties classifications (for example infirm or walk-in servicing required) – this has an impact on how many bins are likely to be at which properties (often this can be extracted from combinations of ratepayer service records linked to lot numbers).
Other useful statistics and data• projected population growth by suburb expected over life
of contract• the waste streams involved per bin type and average
weight/volume per stream/bin size • likely presentation rates for each waste stream/service type• depot locations and which vehicles work from what depots• fuel locations and truck range between fuel stops• the number and type of available vehicles and their weight
and volume capacity• local labour and operational time limits• how long a typical driver day is expected to be• what driver fatigue rest breaks are required at what
intervals• truck start-up pre-check time allowance (they can’t all get
out the gate at once)• likely truck unload times at landfills• end of shift truck wash and refuel time allowances• landfill or transfer station disposal site addresses for
geographic locations • site operating hours if these are likely to be restrictions.
Challenges facedMain operational challenges• quantifying existing bin collection runs• getting the unions onside• changes to start and finish times/overtime• some drivers fear technology• getting internal departments onside (fleet, IT, GIS).
Geographical challengesWhile in a normal city council the terrain may be relatively flat, population density in areas can still vary considerably. Satellite pockets of suburbs around shopping centre clusters, dispersed along main road arteries from rural fringes don’t tend to follow any regular geometric pattern. Denser city dwelling areas and smaller properties means more lifts per kilometre compared to sparser coastal stretches meaning longer travel for less bins. Also the distance of different run areas away from depots or disposal sites means differing transit times and less available pickup time in a run area if you have more travel time getting to and from the area or to and from the disposal points.
Putting the dots on the mapPlotting residential services within day of service run boundariesGeo-coding is a process that involves translating a street address to a dot on the map. If the address is wrong, the dots can’t be plotted correctly so this process of correcting addresses – although a simple task, it can be very time

Waste equipment
consuming. Geo-coding utilises property and street centreline data. Property geo-coding should provide a match rate better than 95%, but relies on up-to-date cadastre (geo reference property data layers). Data quality is usually not an issue where you can use a single property identifier field (a second property identifier such as lot plan may also be utilised during geo-coding). Adequate data currency might require a property table update periodically for high growth areas.
For properties which don’t match to property identifier, a street address geo-code is attempted. This attempts exact address, street name only, suburb and finally postcode matching.
Geo-coding processes are usually able to match based on aliases for street type and to correct for ‘vanity’ suburb allocation (not likely to be an issue with rateable property addresses). New subdivisions with no property or address information may not match with either geo-coding method.
Drawing route boundaries Drawing route boundaries with modern GIS mapping systems is also an easy process – as simple as clicking lines on a map – and you can often scan in a picture of your old paper maps to use as an underlying guideline or look at aerial photos or satellite views to check property features so you know lines are in the right place. This is where we found you could get great driver involvement as they could relate to the picture and aerial views; they also felt important being consulted for advice. This ensures driver buy-in at an early stage.
Check your run area maps Using GPS tracking you can validate where trucks are actually travelling as well as see what actual pick-up vehicles are doing on the run. Simple integration to PTO gear or electronic piezo switches linked to lift arm activation can give you such presentation rate data.
Let the computer do the countingThe next step is to get the computer to count the dots within the day of service plots. This helps to summarise key statistics like kilometres in each collection area and number of lifts or bins in the area. Once you have these
counts summed up based on the number of services within the run boundary, you can go back to moving the boundaries and have the computer count up the bins within the borders.
Multi-vehicle route planningOur experience from this project found that the trickiest technical processes to master were what the mapping gurus called Multi-Vehicle Capacitated Route Planning (MVCRP) algorithms.
These took into account the wide range of factors from depot start times, shift duration limits, driver vehicle checks, service point locations, disposal tip locations, vehicle capacities, ideal shift lengths, vehicle refuelling time, truck wash times and lift rates by area type (city, urban, rural), and were used in formulae to suggest how to break a day of service area up into roughly equal workloads in time, travel and number of lifts for the nominated truck capacity (multi-vehicle capacitated planning).
In simple terms, this means the computer mapping technology can help to auto-divide a designated day of service area into even workloads for the number
of trucks you have within nominated lift, time and volume or tonnage capacities.
All that then needs to be done is to road-test the result and override with manual boundary adjustments where necessary. For this again you can use live GPS data to validate assumptions made in optimising factors.
Side of street route optimisingThe next step is to get the computer to suggest which way the trucks should travel within any nominated single truck area to get the least amount of travel. In addition to this, you may also want to add counts for items you want to minimise – such as cross traffic turns or number of reversing points or U-turns – all of which can be occupational health and safety risks to people on the street, as well as to minimise risk of vehicle damage.
ConclusionAt the completion of our project we had achieved the following:
We’d reviewed and equalised existing collection runs from the amalgamated councils. This resolved the large disparity in the length of time vehicles are operating per day, with some operators finishing early and some being paid overtime.
Disruption to collection days were kept to a minimum, with only a need to change collection day of service for some 3 000 residents (this can be one of the most
costly areas and complaints contributors if you have to change people’s habits for getting bins out on the right day of the week). After automated mail-outs to affected residents, there were only 12 calls from the public. Given that we now have a technical mapping data base to do calculations on, it is easy to project and balance service counts factored by population growth projections per year as well as being able to adjust for population migrations from one area of concentration to another. We also managed to streamline commercial collection schedules with site access time restrictions and litter bin collection schedules. Projected cost savings for the year (based on 10% labour and fuel savings) amounted to over US$250 000 (R 1.9 million).

Legal
The Consumer Protection Act (CPA) lays
down general principles, as opposed
to the details provided by the Waste
Act and other laws in this field.
Supply chain – strict liability
One of the main differences between the
CPA and the Waste Act is that in terms of
the CPA, any supplier within the supply chain
can be held liable in full for the negligence
of any of the others in that chain, regardless
of whether that supplier (held liable) is
negligent or not. There does not have to be
a monetary aspect for a supply to be created
in this chain. This is in contrast with the
Waste Act in terms of which the liability is
interrupted when the goods/containers are
handed over to responsible people, such
as those who specialise in waste disposal.
Therefore, theoretically, the initial supplier in
the chain can be held liable in terms of the
CPA for the people poisoned by its drums
that eventually end up on a refuse site.
Know the harmScope of harm suffered in terms of the CPA
Suppliers will only be held liable for harm
suffered by the consumer if the harm
relates to the supply of unsafe goods: a
product failure, defect or hazard in goods,
or insufficient instructions or warnings given
to the consumer relating to any hazard
arising from the use of those goods. But,
as above, negligence is not required to
establish liability.
Types of harm covered by the CPA
The harm for which a supplier can be
held liable includes death or injury of
a consumer; an illness of a consumer;
any loss of, or physical damage to any
property, whether movable or immovable;
The Consumer Protection Act diverges from most other legislation as it benefi ts the consumer more on almost every occasion. On this basis, it is the third most important statute in South Africa, behind the Constitution and the Public Financial Affairs Legislation. by Gavin Gow*

Legal
as well as any economic loss that results
from the abovementioned harm – that is,
consequential damages. The CPA contains
important definitions of ‘unsafe’, ‘defect’
and ‘hazard’. It is important that suppliers
of chemicals and hazardous substances
familiarise themselves with these definitions
and take reasonable steps to avoid liability
in terms of the Act.
If there are reasonable grounds to believe
that any goods may be unsafe, or that there
is a potential risk to the public of exposure
to those goods, the National Consumer Com-
mission may require the producer undergo an
investigation as to the nature, causes, extent
and degree of the risk to the public and to
carry out a recall programme on any terms
required by the commission. The Act also
deals with the recovery and safe disposal of
designated products or components.
CPA compliance It is important to ensure that all the
suppliers within your supply chain are CPA
compliant. Besides civil liability through
the courts, the CPA imposes a maximum
sanction of 10% of the annual turnover of
the entire group.
Relevant sections of the CPAWith regard to waste disposal, there are
various very serious sections of the CPA
that have to be complied with. Some of
these are:
• Warnings and instructions: warning of risks
for hazardous goods, for example.
• Safety monitoring and recall (industry
codes).
• Recovery and safe disposal.
• Packaging: This should
enable consumers to
understand the goods
supplied to them and
to see what they are
buying. This should avoid
many returns in the first
instance, to which the
consumer is entitled in
terms of the CPA, due to
implied warranty of quality in terms of
the CPA.
• Product labelling: The CPA also sets
standards for product labels and marketing
of goods and services. A supplier must
not apply a trade description to a product
that could mislead a consumer as to
that product. The supplier must not, by
words or conduct, directly or indirectly
imply a false, misleading or deceptive
representation to a consumer in relation to
the marketing of any goods or services.
• Displaying of prices.
Waste management plan for the packaging and paper industry The Waste Management Plan (WMP) for any
industry must comply fully with the CPA.
There are two key components to the plan –
the waste supply chain and the development
of markets – to absorb the extra waste
collected. There is a specific section of the
CPA that states that where the industry and
WMP, or regulations, have provided for a
goods collection facility for specific waste
types, consumers may dispose or deposit
such goods at such facilities.
No exemption clauses are allowed in terms
of which the consumer waives any rights
accruing to them terms of the CPA. Further,
the original supplier cannot delegate any
responsibilities to the end supplier or
anyone else.

FIVE-YEAR INDUSTRY PLAN
Municipal service delivery in terms of domestic household waste collection and disposal currently varies from very poor to good in South African cities and towns. The Institute of Waste Management of Southern Africa (IWMSA) has identifi ed a few key issues, which require resolution over the next fi ve years so that signifi cant progress can be achieved within this critical fi eld.
IWMSA news
Committed to send waste packing
With the new Waste Act (Act 59 of
2008) now in place, as well as a
new National Waste Management
Strategy, new standards for waste collection
have been gazetted for comment, aiming
to provide the necessary levels of service
delivery required for all citizens. IWMSA
president, Stan Jewaskiewitz says: “In
terms of the new Waste Act, all relevant
waste management facilities will need to be
licensed and appoint waste management
officers who will have significant legal
responsibilities with regard to compliance.
These new and improved standards include
providing more stringent requirements for
landfills, while simultaneously reducing and
limiting the amount of waste that arrives
at landfill, especially hazardous industrial
liquid wastes. Many landfill sites are not
presently licensed and of those that are,
some are poorly run or managed, causing a
detrimental impact on the environment and
local communities. Government recognises
that at local government level, there is a
significant lack of capacity and expertise.
To this end they have initiated a number of
interventions such as training and assisting
with the financing of various initiatives, all of
which entail investing funds into training and
capacity building.” Jewaskiewitz continues:
“We at the IWMSA are proud of our
involvement in municipal training workshops
and are delighted to now offer accredited
basic Waste Management training courses.”
The Department of Environmental Affairs
has been running an annual Waste Khoro
for the past two years, aimed at informing
and up-skilling municipalities to meet
the requirements of the new legislation.
However, many municipalities do not
have the necessary skills, capacity or
management experience to run effective
waste collection and disposal systems. They
also do not have any planning processes in
place and as a result do not have sufficient
financial budgets to implement such
systems. Industrial and commercial waste
are therefore generally handled by private
sector waste companies whose service,
while not excellent, is adequate in respect of
both general and hazardous wastes.
According to Jewaskiewitz, companies in
this sector have already begun a process
of looking into and implementing waste
recycling and waste treatment systems
especially for industry and are gearing up
in anticipation of the implementation of the
new standards.
The IWMSA focuses on providing education
and training for its members, as well as
other interested parties, whether private
individuals or government entities. For more
