Abstract:
Nowadays, Municipal Solid Waste (MSW) becomes a crucial problem worldwide where it is created the impact to environment, social as well as health. The nonŽsanitary landfill is widespread used for waste disposal in the rural area because of its low investment and operation cost. However, it has negative effect on human health and environment. Furthermore, there is still a hidden energy inside this waste; therefore it is needed to treat MSW properly as well as to harvest maximum energy. Hence, this study emphasizes on the development of micro gasification power plant from MSW for municipalities which has a capacity of 30Ž50 ton per day (tpd) and Amnadcharoen municipality was selected as a case study. Currently, 30 tpd of MSW is generated in Municipality. Instead of nonŽsanitary open dumped, this study proposed the Mechanical and Biological Treatment (MBT) combined with the downdraft gasification technology as the integrated waste management technology for material and energy recovery from MSW. Refused Derived Fuel (RDF) obtained from MBT is used as fuel for electricity production by the downdraft gasifier which was conceptually designed by mass and energy balance. From the conceptual design, the downdraft gasification system with the RDF feeding of 17 tpd can produce 780 kW electricity with the overall efficiency of 15 %. By the economical viewpoint, it is feasible and has the payback period of 8 years.
