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
