  1. 1. Waste and Recycling Tim Clark. Adelaide Biocity Studio 2008 Recycling truck emptying its load inside a Materials Recovery Centre (MRF) Zero Waste SA
  2. 2. If we continue to degrade or over-use our environmental resources (natural capital) we will leave future generations with a serious and increasing environmental debt (Suzuki 2003) We need to use our resources more efficiently Waste management and recycling
  3. 3. Modern cities have a linear metabolism Input resources Output waste We need to close the materials loop by taking measures to prevent waste generation and to reincorporate waste into the economic cycle Girardet Report 2003
  4. 4. The Wuppertal Institute has calculated the ‘ecological rucksack’ (the amount of waste generated in producing everyday products) is 1.5 kg for a toothbrush, 75 kg for a mobile phone and 1500 kg for a personal computer. Use of substantial amounts of natural resources and the associated impacts on the environment can therefore be avoided by reusing or recycling these products in their waste phase and by designing them in a more eco-efficient way. Commission of the European Communities 2003 equals
  5. 5. Waste disposal in South Australia have been reliant on landfill as the lead technology Adelaide currently has six landfills licensed to receive metropolitan waste streams <ul><li>Southern Waste Depot, Maslin Beach </li></ul><ul><li>Southern Region Disposal Depot, Pedler Creek </li></ul><ul><li>Integrated Waste Services, Dublin </li></ul><ul><li>Waste Management New Zealand, Inkerman </li></ul><ul><li>Waste Management New Zealand, Nuriootpa </li></ul><ul><li>Northern Adelaide Waste Management Authority Balefill, Uleybury </li></ul>At current rate of disposal these sites will meet Adelaide’s requirements for several decades
  6. 6. Waste avoidance, reduction and recovery- material or energy We need to consider Zero Waste SA Waste prevention includes cleaner production processes, better product design and more eco-efficient production and consumption patterns
  7. 7. There are problems with landfill Why is this necessary? <ul><li>Burying waste in landfill prevents ongoing use of that product and potential for higher resource value through reuse, recycling and resource recovery </li></ul><ul><li>Anaerobic decomposition of organic matter leads to greenhouse gas emissions -particularly methane (a more effective greenhouse gas than carbon dioxide) </li></ul>Proper landfill siting, urban encroachment and landfill design, construction, operation and post closure management are essential to control potential impacts such as <ul><li>Leachate </li></ul><ul><li>Dust and mud on the site and prevention of discharge from site </li></ul><ul><li>Odour emission on and off site </li></ul><ul><li>Noise emissions </li></ul><ul><li>Vermin, birds and other disease carriers </li></ul><ul><li>Storage and handling of dangerous substances </li></ul><ul><li>Storage, maintenance and fuelling of machinery and equipment on site </li></ul><ul><li>Litter management </li></ul><ul><li>Traffic management </li></ul><ul><li>Fire prevention, control and associated emissions </li></ul>
  8. 8. Recycling activity in South Australia 2005-2006 Final Report Comparison of reported per capita recycling activity, by State
  9. 9. Annual South Australian landfill diversion and overall waste recycling In 2006-07 2.43 million tonnes of materials was diverted from landfill in South Australia which is an increase of 1.6% from the previous year The SA diversion rate is the highest of any State, exceeded only by ACT The waste to landfill figure is the lowest in the past 4 years The recycling and reprocessing industry needs to continue to grow alongside the growing the population Review of Recycling Material in South Australia 2006/07
  10. 10. Greenhouse gas savings benefit of recycling The recycling of aluminium saved 315,000 tonnes of CO2 equivalent to almost 73,000 cars off the road Review of Recycling Material in South Australia 2006/07
  11. 11. Origin of SA sourced reprocessed materials Majority of recycled materials are from construction and demolition, and commercial and industrial sectors Municipal recycled materials makes up only 16.8% of total materials processed Review of Recycling Material in South Australia 2006/07
  12. 12. Kerbside recycling Councils have been at the forefront of encouraging householders to contribute to recycling the provision of either separate bins or separate compartments in existing bins for recyclables puts onus on householders City of Marion Council After collection all garbage, recycling and green organics are taken to the Adelaide Waste and Recycling Centre on Morphett Road at North Plympton. The Centre incorporates: * domestic and commercial transfer facilities for waste and recycling * residential and commercial green organics drop-off and pre-processing * hard waste transfer and recycling * a full Materials Recovery Facility.
