Abstract

This study examines the potential for RDF production from a mixture of municipal solid waste (MSW) using bio-drying technology to be used as an alternative fuel industry in Indonesia. The most suitable waste for the production of the RDF method is waste that has a high carbon content after being separated from recyclable waste. This bio-drying method is usually carried out by an aerobic process. The advantage of the bio-drying process is that it reduces waste mass and emissions of CH4, CO2, SO2, NOX, and dust emissions from landfill waste into the atmosphere. An economic model for the use of RDF in the Indonesian industry, especially the cement plant, has been created. This model produces RDF material as an alternative fuel to replace coal which is currently used. The cost analysis carried out will result in economic savings and is environmentally friendly and can be used for other industrial fuels. In this study, urban waste that is processed into RDF is 120 tons/day. Research shows that adding 58% RDF as a substitute fuel, equivalent to 70 tons/day of fuel used in a cement kiln would save 70 USD/day in petcoke costs with 65.8 tons/h of CO2 being emitted into the atmosphere. The bio-drying process allows a decrease in the wastewater content of up to 59% and an increase in the calorific value of the waste (LHV) by 600% (14.55 MJ/kg), as a result of the decrease in the wastewater content.
