  4. Extraction to dumping Extraction Production Disposal Distribution Consumption

  5. 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

  6. 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

  7. Reduce, reuse, recycle Disposal

  8. Types of waste

  10. 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

  11. 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

  12. 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

  13. 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

  14. 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
