Waste facts
• 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
6000 tons of waste is produced daily in CT
Our Wasteful Economy
• 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
90% of materials used in production are wasted:
Reduce, reuse, recycle

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
• Carbon paper, stickers, self-adhesive paper.
• Chemically treated fax or photo paper.

Reduce waste generation
At the office
A typical office environment will have large quantities of paper or cardboard waste,
with some plastic – often related to packaging – and
some electronic or hazardous waste
At your desk
• Re-use envelopes, paper clips and wrapping paper
• Reuse paper printed on one side • Use paper made from recycled product
that is chlorine-free and has the Forest Stewardship Council (FSC) logo
• 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
• Buy environmentally friendly stationary• Use refillable ink cartridges and ensure
that old cartridges are disposed of safely• Ensure that your electronic waste is
disposed of safely
Kitchen / canteen
The office kitchen or canteen would mostly include
packaging waste such as paper, plastic, polystyrene, glass or tin cans, as well as
organic waste.
Kitchen / canteen
• Avoid disposable cups and plastic lids in your office
• Use cutlery made from stainless steel instead of disposable plastic
