Conversion of municipal solid waste to refuse-derived fuel using biodrying

Abstract

Municipal Solid Waste (MSW) in Indonesia comes from urban settlements, markets, and industries. MSW decomposes naturally and without being used at all. The purpose of this study to convert MSW to refuse-derived fuel (RDF) using biodrying. The research was conducted on a laboratory scale using a biodrying reactor. The biodrying process takes place aerobically with an airflow rate of 6 L/min, the highest temperature reaches 60oC on the third day and the water content on the 21st day is 32.65%. The final RDF calorific value is 6,102.82 cal/g. This calorific value is equivalent to low-energy coal (brown coal). RDF from MSW can be applied to the cement industry that requires heat >6000 cal/g, PLTU requires 5242 cal/g, the metal industry requires 6000 cal/g, and the paper industry requires 5240 cal/g to carry out the production process.
