Waste Recycling | Biocity Studio

Published on

Each household produces 681kg of waste per year. South Australia’s landfills create 60 million cubic metres of landfill airspace. The state is one of the best at recycling and manages to divert 65% recyclable from the landfill. One of the major challenge for recycling is competing with landfills. Cheap landfill costs, disposal contract and global warming are the current crisis issues for waste in South Australia.

Transcript of "Waste Recycling | Biocity Studio"

  1. 1. Waste Recycling liyana mohamed yusof
  2. 2. municipal solid waste ‘ food, packaging, garden organics, plastics, glass, steel cans, paper/cardboard’
  3. 3. commercial & industrial waste ‘ food/kitchen wastes, cardboard, paper, metal, wood/timber, tyres/rubber, plastics’
  4. 4. construction & demolition waste ‘ soil , rocks, rubble, asphalt, timber, metals, concrete, plastics, plasterboard, asbestos ‘
  5. 5. ‘ 681 kg of waste per household per year is collected from kerbside in metropolitan and 722 kg in non-metropolitan’
  6. 6. factors <ul><li>The growth of population </li></ul><ul><li>Wealth </li></ul><ul><li>The growth of technology & economy </li></ul><ul><li>The growth of packaging industry and industrial </li></ul><ul><li>products </li></ul><ul><li>Lack of public awareness </li></ul>
  7. 7. factors <ul><li>The growth of population </li></ul><ul><li>Wealth </li></ul><ul><li>The growth of technology & economy </li></ul><ul><li>The growth of packaging industry and industrial </li></ul><ul><li>products </li></ul><ul><li>Lack of public awareness </li></ul>

  10. 10. factors <ul><li>The growth of population </li></ul><ul><li>Wealth </li></ul><ul><li>The growth of technology & economy </li></ul><ul><li>The growth of packaging industry and industrial </li></ul><ul><li>products </li></ul><ul><li>Lack of public awareness </li></ul>

  12. 12. landfills <ul><li>The important part of South Australia’s waste management </li></ul><ul><li>infrastructure are landfills because the waste disposal here </li></ul><ul><li>has been dominated by these landfills. </li></ul><ul><li>Adelaide is served by : </li></ul><ul><ul><li>Southern Waste Depot , Maslin Beach </li></ul></ul><ul><ul><li>Southern Region Disposal Depot , Mclaren Vale </li></ul></ul><ul><ul><li>Integrated Waste Services Balefil, Dublin </li></ul></ul><ul><ul><li>Waste management New Zealand, Inkerman </li></ul></ul><ul><ul><li>Waste management New Zealand, Nuriootpa </li></ul></ul><ul><ul><li>Northern Adelaide Waste Management Authority Balefil, Uleybury </li></ul></ul><ul><li>These infrastructures provided 60 millions cubic </li></ul><ul><li>metres of landfill airspace </li></ul>
  13. 13. existing issues <ul><li>Low landfill costs </li></ul><ul><li>Disposal contract </li></ul><ul><li>Global warming </li></ul>
  14. 14. existing issues <ul><li>Low landfill costs </li></ul><ul><li>Disposal contract </li></ul><ul><li>Global warming </li></ul><ul><li>Major landfills service in Adelaide and small rural landfills </li></ul><ul><li>received 12.8 million tonnes of solid waste every year. </li></ul><ul><li>This is happening because due to low landfill costs, it is </li></ul><ul><li>more effective to dump rather than recycle. </li></ul><ul><li>When the waste is disposed to landfill, we will bury many </li></ul><ul><li>useful resources and prevent ongoing use of the materials. </li></ul>
  15. 15. existing issues <ul><li>Low landfill costs </li></ul><ul><li>Disposal contract </li></ul><ul><li>Global warming </li></ul><ul><li>It needs a high level of design to ensure the sitting, </li></ul><ul><li>rehabilitation and management of the landfills. </li></ul><ul><li>The operators of the landfills has to encourage the local </li></ul><ul><li>government and businesses to enter the long-term </li></ul><ul><li>contracts and set a minimum volume of waste to them. </li></ul><ul><li>This again will encourage them to dispose the waste to </li></ul><ul><li>the landfill instead of recycling. </li></ul>
  16. 16. existing issues <ul><li>Low landfill costs </li></ul><ul><li>Disposal contract </li></ul><ul><li>Global warming </li></ul><ul><li>In landfills, the anaerobic (without oxygen) decomposition </li></ul><ul><li>of the organic leads to emissions especially methane </li></ul><ul><li>and also carbon dioxide and nitrous dioxide. </li></ul><ul><li>Methane is more effective green house gas than carbon </li></ul><ul><li>dioxide and has much greater greenhouse effect. </li></ul><ul><li>However the amount of the methane depends on the </li></ul><ul><li>quantity of the waste and the design n management </li></ul><ul><li>of the landfill site. </li></ul>
  17. 17. future issues <ul><li>Shortage of landfill </li></ul><ul><li>In 2004 the disposal from the six landfills licensed to </li></ul><ul><li>received Adelaide's waste will only meet the Adelaide’s </li></ul><ul><li>requirement for several decades. </li></ul><ul><li>The will be possibilities that Adelaide will has not enough </li></ul><ul><li>space for landfill sooner than that. </li></ul><ul><li>They will need a new landfill and this can create more </li></ul><ul><li>issues in finding the logistic. </li></ul>
  18. 18. Amount of waste disposed of to landfill increased from 860,000 tonnes in 1995-1996 to 1,1100 tonnes in 2001-2002
  19. 19. <ul><li>32,800 tonnes from domestic waste </li></ul><ul><li>169,000 tonnes from commercial & industrial waste </li></ul><ul><li>509,000 tonnes from construction and demolition waste </li></ul>
  20. 20. recycling <ul><li>SA is one of the most best in recycling. It managed to divert </li></ul><ul><li>65% recyclable from the landfill </li></ul><ul><li>The waste is either recycle within the plant or will be </li></ul><ul><li>transferred to business that could process the material. </li></ul><ul><li>One of the major challenge for recycling is they have to </li></ul><ul><li>to compete with landfills. </li></ul><ul><li>Other problem is low value waste and mixed of waste </li></ul><ul><li>make it difficult to recover usable materials. </li></ul><ul><li>This waste will then be disposed in the cheapest way </li></ul><ul><li>which is landfill. </li></ul>
  21. 21. “ Despite increase in the number of people recycling, the amount of waste going to landfill is increasing’ The 2003 State of the Environment Report for South Australia
