National Workshop on Pro-Poor and Sustainable Waste Management in Secondary Cities and Small Town Prospects for the Application of Anaerobic Digestion Process to Treat Municipal Solid Waste/MSW in Indonesia by: Rudy A. Arifin Head of Subdirectorate of Municipal Solid Waste Management Directorate of Environmental Sanitation Development Directorate General of Human Settlements Ministry of Public Works and Housing Republic of Indonesia 2014 national policy and strategy INDONESIA Population 2012 : 244,723,038, with annual growth rate 1.49 % Area : 5,180,053 km2 Number of provinces : 34 Number of cities/districts : 511 Number of metropolitan/big/medium cities: 10/13/56 Daily MSW generation in urbanized area: 76,305 tons The Levels of MSW Handling System ARAS SPASIAL TUJUAN Spatial 1. Regional PENDEKATAN Approach Goal To handle in the regional level between cities or districts To develop a regional handling RUANG LINGKUP KEGIATAN KETERPADUAN PROGRAM Compatibility Activity MSW treatment plant Regional landfill 2.

Community To reduce the MSW quantity and polution potential, for optimizing the transport and further treatment processes To reduce and partially treat MSW To facilitate the construction of 3R infrastructures To provide the collection and transportation infrastructures Priority area (KADAL program), regional economic development (KAPET program), real estate program, and MSW treatment plant program 4. Neighbourhood To enforce reduce, reuse, and recycle of the MSW To enforce the community involvement To educate from school level To disseminate the campaign for MSWseparation at the MSW source To endorse the 3R activity Pilot project of 3R infrastructures Green & Clean City program To endorse the composting process or organic MSW at the household level Composting of organic MSW program 5. Household To reduce the quantity of organic MSW from the source of MSW generation To treat organic MSW to solid compost The Paradigm of MSW Handling System in Indonesia OLD NEW MSW Reduce Collection Reuse MSW Transport Residue Disposal Transport Treatment Recycle Aspects in MSW Handling System TECHNOLOGY MSW HANDLING SYSTEM FINANCIAL LEGAL COMMUNITY INVOLVEMENT ORGANIZATION Policy at the National Level Target based on the Medium Term National Development Plan 2010-2014 1. To increase the MSW collection by 75%. 2. To increase the performance of landfills in 210 cities. 3. To reduce MSW quantity and polution potential. Program 1. To promote 3R (Reduce, Reuse, and Recycle) activities . 2. To educate through campaign. 3. To enhance institutional development. 4. To optimize and develop MSW infrastructures. 5. To revitalize landfill and apply the regional system for landfill. 6. To promote private investment. Policy 1. To reduce MSW generation rate and polutant potential, from household level. 2. To increase the role of community and private sector as a partner in MSW handling. 3. To increase the service coverage and performance of MSW handling system. 4. To develop the institution and legal aspects. 5. To find the alternative of financial resources. Strategy at the National Level To optimize the use of existing infrastructures. To increase the service coverage. To increase the capacity of MSW infrastructure. To revitalize the landfill. To optimize the current landfill process towards controlled landfill (for small and medium cities) and sanitary landfill (for big and metropolitan cities). To increase the implementation of regional landfill. To perform research in appropriate and environmental friendly technologies. Readiness Criterion to Get Technical Assistance from Central Government – (1) In line with the Ministry of Public Works Strategic Plan. Listed in the cities’/regencies’ Medium Term Investment Plan Document. Listed in the City Sanitation Strategy (Program Memorandum is preferred) In line with the duty of the Directorate General of Human Settlements. Other criterion: The availability of managing institution. The availability of land, detail engineering design, and environmental impact assesment. MoU between local governments (for regional landfill). Readiness Criterion to Get Technical Assistance from Central Government – (2) Commitment to optimize the existing infrastructures. Commitment from the Local Government to: Sign the MoU and allocate adequate funding for institution strengthening as well as for operation, maintenance, and rehabilitation of the infrastructures. Developing and/or provide supporting infrastructures. Prepare the Loan Proposal and Loan Acceptance by the Local Government. Clarify the performance indicators, as well as the program output and outcome. MSW treatment plants (communal base vs institutional base) Communal Base vs Institutional Base As the policy of Ministry of Public Works, in regards to provide the basic need, thus landfill technology has currently been selected as the most efficient technology that can be affordably operated by Municipalities An urge to provide other technologies than landfill, has marked the construction of institutional base MSW treatment plants, as has been constructed in Kota Bima, Kota Banda Aceh, and Kota Tangerang Selatan, as prototype However, Ministry of Public Works pushes the construction of institutional base MSW treatment plants that can generate income in an adequate amount, to the private parties through the PPP scheme From these perspectives, Ministry of Public Works focuses on the communal base MSW treatment plants, with the capacity to serve 100200 households/day or equal to 1.5-3.0 m3 of mixed MSW/day MSW treatment plants (institutional base) In Kota Bima, Nusa Tenggara Barat capacity 20 m3 of shredded organic MSW/day MSW treatment plants (communal base) Process Selection The scarcity of land in cities for construction of landfill, as the solely centralized MSW treatment plants The need to push the technological concept “the highest ratio between MSW treatment capacity within the smallest requirement of areas, in affordable cost and ability to be operated-maintained-rehabilitated” The initial step through the aerobic (windrow composting) process, that has been commonly practised and spread in almost 500 locations all over Indonesia, with the communal-base mechanisms Passive aerobic process would not be able to cope the small requirement of space, due to the shallow organic waste heap height as the limiting factor The process modification through anaerobic process that can be more resilient in term of organic waste heap height, enriched with the double-stage anaerobic process to enhance the process performance Additional by-products can be harvested through anaerobic process, such as biogas, as the renewable energy source, that can be used as the partial substitution of energy for cooking purposes, with the communal base mechanism Aerobic (Windrow Composting) Process capacity 0.5 m3 of shredded organic MSW/day MSW treatment plants with communal base: module SIKIPAS (SIstem Komunal Instalasi Pengolahan Anaerobik Sampah) Process Flow 20 days of anaerobic process + 20 days of aerobic process biogas generation unit hydrolysis unit solid compost leachate collection unit electricity generation unit biogas biogas combustion unit adjusted pH to 6.5-7.5 leachate resirculation unit biogas measurement unit liquid compost Process Specification operating capacity 1 m3/day ;
