Discard/dump or burn
In order to reducepollution:sanitary landfilland incineration
Soil, water and airpollution of thebiosphere, ourhabitat
Solid Waste Management | Dr. Lucas Dengel��� Auroville Green Practices Seminar 2010 8 of 17
• Blocked open sewers > fly & mosquito breeding >feces-borne & mosquito-borne diseases
• Groundwater becomes polluted microbiologically(sewage, feces) and chemically (e.g. heavy metals) >distant groundwater sourcing and depletion
Public Health & hygiene concerns
Solid Waste Management | Dr. Lucas Dengel��� Auroville Green Practices Seminar 2010 9 of 17
Air pollution by dioxins and furans caused by low-degree smoldering fires burning PVC (halogen-containing plastics & plastics additives)
bio-accumulation in fat tissues: mother milk / nervous tissue, seriousdamage to fetus and embryo – see agent orange damage in Vietnam war

Moral IssuesThe Management of the commons
Solid Waste Management | Dr. Lucas Dengel��� Auroville Green Practices Seminar 2010 11 of 17
Incineration
• High temperatures• Fast cooling• Air filters• Adequate use of fly ash
Technical Issues
Sanitary landfill
• Lining• Covering• Collection & treatment of leachate• Methane retrieval & use
No universal solution for all kinds of waste
Solid Waste Management | Dr. Lucas Dengel��� Auroville Green Practices Seminar 2010 12 of 17
• Adequate collection services missing• Adequate processing services missing• Capacity building at lower levels required• Corruption in administrative & political offices

Reduce – Re-use – Recycle
• Avoid unnecessary packaging (value addition, branding…)
• Implement waste separation
• Demand adequate collection services
• Compost bio-waste, channel it towhere there is a need, staydecentralized as far as possible, keeptransport routes short
• Challenge manufacturers ofhazardous waste (e.g. batteries) andcomplex waste (e.g. IT industry) torecycle
