  1. Benefits of Managing Solid Waste Non-sanitary landfills: Risk assessment & risk mitigation

  2. Indonesia, country of natural wealth !! 2/21

  3. Indonesia, country of natural wealth ?? 3/21

  4. PRESENT SITUATION OF LANDFILLS IN INDONESIA • Landfilling is major route for processing of wastes • Alternative solutions, including incineration, composting or separate collection with recycling are hardly applied • These alternatives are costly, are not suitable or require big change in waste management system) • Collection rate of waste is 50-60% (so, much waste is dispersed into environment) 4/21

  5. WHAT IS THE (REAL) COST OF LANDFILLING ? • 1. Landfills causes sliding of wastes (in 2006 many people died because of this problem) 5/21

  6. WHAT IS THE (REAL) COST OF LANDFILLING ? • 2. Landfills creates unhealthy situation for men (gases, smoke, hurting, diseases) 6/21

  7. WHAT IS THE (REAL) COST OF LANDFILLING ? • 3. Biogas from landfills creates risk for explosions (fires, explosion of wastes, etc.). Biogas must be released into atmosphere 7/21

  8. WHAT IS THE (REAL) COST OF LANDFILLING ? • 4. Leachate water is hazardous and pollutes the environment (as result from rain water infiltrating the landfill). 8/21

  9. WHAT IS THE (REAL) COST OF LANDFILLING ? • 5. Health risk for workers on or near landfill (diseases, medical cost) 9/21

  10. WHAT IS THE (REAL) COST OF LANDFILLING ? • 6. Global Warming (sea water rising, hurricanes, drought, diseases etc.) 10/21

  11. WHAT TO DO ? 11/21

  12. STRATEGY, PLANS, MEASURES • National waste strategy: should support short term and long term solutions. Should promote sustainable solutions. • Appropriate plans: should be realistic from technical and financial point of view. Should focus on modernizing the landfills. • Measures: immediate measures should mitigate the immediate risks. Should focus on major risk: collection and utilization of the biogas 12/21

  13. IMPORTANT IMMEDIATE MEASURE • Collection of biogas: • mitigates the risks for humans • improves waste management operations (and increases income) • promotes production of sustainable energy & local energy generation • promotes transfer of technology to regions of Indonesia • generates income from electricity 13/21

  14. BIOGAS • Biogas (containing methane or CH4) is a valuable source of energy but cannot be utilized without measures and investments: • 1st phase: structuring of waste disposal • 2nd phase: placing of biogas collection system (including covering of waste) • 3rd phase: production of electricity 14/21

  15. BIOGAS 15/21

  16. Biogas investment programme for regions of Indonesia - Example of Palu 16/21

  17. Palu landfill was visited, investigated and assessed. 17/21

  18. Palu landfill was visited, investigated and assessed. 18/21

  19. Some observations on Palu landfill: • some technical improvement measures were taken (covering) • part of landfill was not well organized • neighbouring people are afraid of extension of landfill (leachate) • capacity of landfill to receive waste is still large (> 2012); more waste means more income • registration of incoming waste should be improved • biogas is not collected and spilled into atmosphere • Regency and waste managers support improvement programme 19/21

  20. Recommendations on waste management and biogas collection: • Be realistic and do not everything at once • “First things first” • Improve overall situation at landfill and make proper plan • Start recovering biogas ! • Generate jobs, acquire technological know-how, create better life for all • Promote biogas collection projects under CDM 20/21

  21. L eft: uncontrolled dumping of waste; right: organized disposal of waste and covering of landfill body 21/21
