Energy recovery potential from excavating municipal solid waste dumpsite in Indonesia

Abstract

There is no proper intermediate treatment for municipal solid waste in Indonesia before dumped in a landfill. Most of the Indonesian dumpsite already over capacity and need intensive treatment. This study examines Jatibarang Dumpsite in Semarang City, Indonesia to assess the material recovery potential for solid fuel. After excavation obtained material consist of 46% of the combustible material (organic and plastic), 52% of the fine particle, and 2% of the incombustible material (metal and glass). A simulation of incineration with the steam turbine is used to predict the electricity generation. The simulation results show that the amount of electricity produced could reach 461.67 kW with CO2 emission up to 0.18 kg/sec.
