PRARANCANGAN PABRIK REFUSE DERIVED FUEL DARI SAMPAH PERKOTAAN DENGAN KAPASITAS 45000 TON/TAHUN

Abstract

Refuse Derived Fuel (RDF) is a type of alternative fuel that can be used as a substitute for coal that is inherently environmentally friendlier as it is sourced from Municipal Solid Waste (MSW). Currently the market for RDF is quite small both in Indonesia and other countries around the world, but amid growing concerns of climate change and stricter emission regulation for industries, it is a very real viable option of producing fuel while reducing waste in landfills. Taking this into account, establishing an RDF plant in Indonesia is promising, either as its own production plant or as a utility plant for existing production facility that employs coal as a fuel source. To meet domestic and foreign needs, the plant is planned to be built in Kesugihan district, Cilacap regency with a production capacity of 45,000 tons/year. The process uses MSW as with a feed of 325 tons/day or 13541.6667 kg/hour into 5956.7402 kg/hour of pelletized RDF or RDF-5 as the main product. The pelletized RDF is set at a price of Rp1.650.000,00 per ton with 2020 as the year of reference. The production steps include the manual sorting of glass from the waste, the sorting of magnetic and non-magnetic metals by magnetic separator and eddy-current separator respectively, the size reduction of the sorted waste, drying of the waste until it reaches 15% in terms of moisture content and finally pelletizing it for easier storage and transport. The side-product of the production is the glass, and magnetic and non-magnetic metals that was sorted. The utilities needed is 1737,5491667 kg/hour of water, 4638.943617 kW of electricity, and 15.6755 kg/hour of compressed air. The amount of labor needed totals at 199 people. Based on the economic feasibility study, the total capital investment needed is Rp304.878.765.091,96, at 100% production capacity the production cost is Rp51.510.848.821,60 with a ROIb of 41.83%, ROIa of 31.35%, POTb of 2.39 years, POTa of 3.19 years, BEP of 26.67%, SDP of 8.53% and IRR of 16.0758%. These results indicates that the RDF plant is economically justified with long term investment in mind.
