24 Waste Management in Asia Region Waste Quantity is less but increasing dramatically Still many people is not receiving waste management services Most of waste is disposed of by open dumping Disposal cost is so cheap and modern technology like incineration is not adapted Regulation is not likely enforced. Not enough experts. Recycling is done by informal sectors.

25 Disposed by Municipality Disposed by Private Company 1 Municipal Solid Waste 3 Waste from Household Wastes from Business Activities Industrial Waste Wastes from Industrial Sector 4Waste Collected by Municipality Waste Brought by Generators Self Disposal Recycle Processing Recycle Processing Final Disposal 2 Designed Disposal Quantity Self Disposal Quantit Recovery of Recyclable Item by Voluntary Citizen Grou Recycle Final Disposal

26 Waste Generation Increases as GDP Increases Waste Generation (g/cap/day) 1, ,000 10,000 (GDP/cap/yr)

27 Municipal Solid Waste Generation (kg/cap/year) High generation group : y=100.72x R= Middle generation group : y=36.73x Low generation group : y=27.544x R= R= GDP (US$/cap./year)

28 Solid Waste Generation in the World until 2050 billion ton/ year 億 / 年 Solid Waste Generation in the World (t/year) 2000 ; 12.7 billion ton 2015: 17 billion ton 2025; 19 billion ton 2050 ; 27 billion ton ASIA Europe Northern America Latin America and the Caribbean Africa Ocea

29 Quantity and Disposal Level of MSW million tons in world (980million tons(60%) in level 1) 790million tons (49%)in Asia (680million tons(86%) in level 1) million tons in world (1400million tons(44%) in level 1) 1700million(53%) tons in Asia (890million(64%) tons in level 1)

30 Strategic Improvement of Municipal Solid Waste Management

31 Improvement To achieve the objectives Current Solid Waste Management Future Gap? Unsanitary Condition, Low public Health Level By Open Dumping, Open Burning and Scattered Waste

32 Sustainable Society and Waste Management Input Better Quality of Life Output resources energy waste Environ mental impact Waste Manag ement Circulative Use of Resources 3R Reduce Reuse Recycle Environmental Policy Water Pollution Control Processing and Disposal of Solid Waste Sludge Air Pollution Control Dust

33 Promotion of a regional 3RSociety in collaboration of the local governments and NGOs/NPOs NPOs Local governments support activities to collect used papers, used magazines, used clothing, etc. by citizens groups, NGOs/NPOs, etc. (group collection ) 1~4/kg of collected recyclables are subsidized. About 3,000 tons/year of solid waste are recycled through this group collection [Details of waste by group collection in Japan (thousand tons)] Group collection of recyclable waste ,638.0 紙類 Papers 金属類 Metals ガラス類 Glass ペットボトル PET bottles プラスチック類 Plastics 布類 Fabrics その他 Others

34 Basic Principle of Waste Management (3R Principles) Reduce Producers (Design for Environment) Consumers (Sustainable Life Style) Reuse Discharge/Classification Collection by Voluntary Group Recycle Municipality (Material and Energy Recovery) Proper Disposal

35 Objectives of MSW Management Improvement of Public Health Level Protection of Living Environment Benefit provided by waste management should be maximized.

36 Improvement of waste management Introduction of continuous-operational furnaces in waste incineration facilities contributed to reducing gas emission Liner sheet and effluent treatment facilities are utilized in sanitary landfill sites 1960s Present 1970s Present

37 Waste Management and Environmental Risk Management Input Resources/ energy Waste management Landfill Circular use of resources Reduce Reuse Recycling Leachate treatment Dioxins Heavy metals BOD/COD Vent gas treatment Dioxins Soot and dust HCl, NOx, SOx Environmental Risk Management Solid waste Collection/ transportation Wastewater treatment Dioxins Heavy metals Output Incineration

38 Improvement toward Better Waste Management Refuse Collection Coverage Open Dumping Sanitary Landfill Incineration Rate for Combustible Waste Land fill Disposal Rate Recyclin g Rate W aste Generation Rate

39 Constraints Limited Budget (Efficiency) Limited Man Power Limited Equipment Limited Facilities Limited Landfill Space (Volume Reduction) No Environmental Impact (Risk Management) No Health Impact Natural Resource Conservation (Recycling)

40 Cost-Benefit Analysis Now Future + Cost Public Health Living Environment Public Health Living Environment Benefit

41 Cost and Benefit Before and After Cost or Benefit (yen/ton) β0 Environmental Conservation β Cost C0 Public Health C β0 C0 0 now β/ c 1.0? Future (Improvement)

42 Cost-Benefit Analysis Cost Budget =C+ΔC Waste Management Budget For Human resource development And to buy Advanced facilities Benefit Public Health=B1+ΔB1 Living Environment=B2+Δ B2 ΔB1+ΔB2 ΔC > = 1

43 Benefit provided by waste service should not be underestimated

44 Financial Mechanisms Solid waste may generate financial resources Regional management to recover material and energy and to dispose of solid waste may be better. Central government should finance to built essential waste management facilities with the help of international financing banks to improve public health and environmental. PPP (Polluter pay principle ) apply for waste management basically.

45 Level of risk arising from landfill site Acceptable risk: Level of risk the society can accept (tolerable risk level) Risk arising from stable type landfill sites High cost High Low Desired level of appropriate treatment Landfill of sludge Landfill of sludge Low cost Landfill of shredder dust and plaster board Landfill of shredder dust and plaster board About the cost: Tolerable risk level has come down with time. The cost of responding to the contemporary acceptable level of risks (to satisfy the desired level of appropriate treatment) goes up, accordingly. 1970s 1980s 1990s 2000s 2010s Decade (period)

46 Disposal Cost goes up as GDP increases Disposal Cost ($/ton) 0 0 1,000 10,000 GDP/cap/yr

47 Cost payer of MSW Management Separation/Stock Consumer Tax Municipality Collection Transfer Recycle Incineration Land fill Fee Producer Containers and Packaging Recycling Home Electronics Recycling Automobile Recycling

48 Capacity Development Constant improvement of solid waste management is required. Create section of 3Rs and/or solid waste management in local and central governments. Workers in MSW should be trained and educated always and respected and treated as professional staffs. Then efficiency of waste management will be improved. Experts conducts Cost/Benefit analysis for service of solid waste management. Experts can develop capacity of human resources, institutions, and science and technology.
