Utilization of municipal waste as refuse-derived fuel – RDF (Indonesia)

The Griyo Mulyo Final Processing Site (TPA) as the only final waste processing facility owned by Sidoarjo Regency receives a waste generation of 201,975 tons/year in the 2022 period. As much as 82.2% of the total waste is landfilled at the landfill without prior processing. Therefore, this research was conducted to examine the potential for reducing waste at Griyo Mulyo TPA with RDF technically. In addition, an analysis of the feasibility of RDF processing and an analysis of the environment resulting from the process was carried out using the integrated risk-based approach (IRBA) risk analysis method. The condition of RDF financial processing needed to be analyzed financially, whether this activity could be said to be feasible according to the parameters of NPV, BCR and IRR. Data on sales of RDF results, RDF investment costs and operational and maintenance costs were required. In terms of environmental impact, an environmental risk index assessment and potential hazard of waste landfilling were carried out based on the potential for waste reduction in TPA by RDF processing.
