Technical and financial feasibility study of utilization municipal solid waste as Refuse-Derived Fuel (RDF) in Griyo Mulyo landfill

Griyo Mulyo landfill, the only final waste processing facility owned by Sidoarjo Regency, received a waste generation of 201,975 tons/year in 2022. Most of the municipal solid waste received by the Griyo Mulyo landfill was straightly dumped at the old landfill at 82.2% of total solid waste. Therefore, this research examined the potential for solid waste reduction at Griyo Mulyo final processing site with the Refuse-Derived Fuel (RDF) plant. In addition, an analysis of the financial feasibility of the RDF process and the environmental impact resulting from this process was also carried out. In this study, an analysis of the generation, composition, and density of solid waste received by Griyo Mulyo Landfill was carried out. From these data, the calculation of the mass balance of waste processing is carried out. The financial condition of RDF processing needs to be analyzed for financial feasibility, whether this activity is economically feasible. Some financial data required to calculate feasibility are sales of RDF products, RDF investment costs, and operational and maintenance costs. The result shows an average reduction in RDF raw material was 7.72% annually. The financial analysis on waste recovery to the RDF conversion system on Griyo Mulyo final processing site is feasible to be applied.
