Characterization of municipal solid waste for waste to energy feedstock in Jakarta

Abstract

The characterization study of municipal solid waste for waste to energy facility is very important to Jakarta City because of its waste is still in mixed condition and may contains several materials those are not suitable for incinerator. The purpose of this study was to determine the character of the waste from several sources (shopping areas, office areas, industrial areas, city parks, and households) in the city of Jakarta and to analyse the quality of the waste to be feedstock of incinerator. The research used a random sampling method for the wastes which were transported to the Bantargebang final disposal site. Samples were taken proportionally from the garbage truck to determine the composition, proximate and ultimate analysis. The results showed that wastes were dominated by combustible material and had a good potential as an incinerator fuel in terms of the characteristics of moisture content (less than 50%), volatile matter (above 25%) and ash content (less than 60%), as well as its LHV (above 6 MJ/kg). However, the existence of bulky waste, hazardous waste, non-combustible waste, and several types of waste that are not allowed to enter the incinerator needs to be a concern. Those wastes potentially interfere the performance of the incinerator.
