Waste facts
6000 tons of waste is produced daily in CT
• 2.2 mil tons / year
• 1.7 kg waste / person / day
Waste produced yearly would fill a row
of trucks the distance from CT to Jo’burg
Our Wasteful Economy
90% of materials used in production are wasted:
• To produce 1 ton of paper, 100 tons of water is used
• 1 litre of beer requires 10 litres of water in fermenting
• Producing a cellphone requires 75 kg of resources
• 1,5 kg of coal, oil and water makes 1 toothbrush

Glass
• Glass is a valuable resource that should not
just be thrown away:
• It takes 1 ton of cullet (recycled glass) to
make 1 ton of glass bottles
• Cullet melts at a lower temperature which
saves energy
• 4,5% of landfill site is glass
Glass – not recyclable
• Drinking glasses
• Cups, saucers and ceramic ware
• Sheet glass, such as windscreens and
window panes
• Light bulbs and tubes, including fluorescent
lights
• Mirrors and reinforced glass
• Car headlights
• Laboratory glass
Tin cans and metal
• Tins are100% recyclable and can be used
time and time again
• Cans are the most recycled form of
packaging in Africa : 66 % in SA
• Cans chill quicker in a fridge than any other
packaging - saving electricity
• They stack closer and take up less fridge
space – saving transport
Tin cans and metal
• Please rinse out food tins before recycling
• Motor oil cans should be kept separate
• 70% of recycled scrap metal comes straight
from the industry waste stream, not
consumers
Paper
• 38% of our landfill is paper
• Recycling 1 ton of paper saves 17 trees
• FSC promotes responsible use of forests look for the FSC logo on paper
• Paper made from sugar cane is renewable
and better for environment
Paper – not recyclable
• Wet or dirty paper, such as tissues, paper
towel, food wrappings, paper with spills,
paper plates and cups
• Wax, plastic or foil-coated packaging, such
as milk cartons, bags for dog food or potato

or cardboard waste, with some
plastic – often related to
packaging – and some
electronic or hazardous waste
At your desk

wrapping paper
• Reuse paper printed on one side
• Use paper made from recycled product
that is chlorine-free and has the Forest

• Set your printer to print both sides by default
• Become a paperless office
At your desk
• Sign documents with digital signatures
• Do not print agendas and minutes for
meetings and rather use electronic
equipment
