THE ENERGY POTENTIAL OF MUNICIPAL SOLID WASTE FOR POWER GENERATION IN INDONESIA
Keywords:
Energy potential, Municipal solid waste, Electrical energy, Power plant.Abstract
Utilization of municipal solid waste (MSW) as fuel in power plants in Indonesia has gained the attention of the government and investors. For this study, the estimation of energy potential of MSW was conducted to determine the potential of electrical energy that can be generated in each city and the economic value of MSW as a fuel in the power plant in Indonesia. In estimating the energy potential of MSW in Indonesia, ten cities with large population which produce large volume of MSW were selected. The MSW energy potential estimation was 2,991,905 MWhr/year of ideal electrical energy, 1,172,380 MWhr/year of actual electrical energy, 343 MW for capacity of power plant, 2,034,510 tons/year (about USD 170,898,840) for economic potential of MSW; coal - equivalent and of 1,130,405 tons/year (about USD 678,243,000); oil - equivalent. Combustion of one ton of MSW can produce about 2.5 tons of steam, about 0.5 MWhr of electrical energy, and about 0.021 MW or 21 kW of power. Based on the calorific value of the fuel, one ton of MSW would be equivalent to 0.3 tons of coal or 0.2 tons of oil. Based on the results obtained, it can be concluded that MSW in ten cities in Indonesia has the energy and economic potential to be used as fuel in power plants. Utilizing MSW as a fuel in power plants is one solution that can overcome environmental issues and the shortage of electrical energy in Indonesia.References
