This study assesses the feasibility of implementing a 1 MWe gasification plant fueled by Refuse-Derived Fuel (RDF), proposing an innovative solution for municipal solid waste (MSW) management and decentralized renewable energy generation in small and medium-sized cities. By integrating data from a pilot RDF briquetting and gasification facility in Brazil-along with Computational Fluid Dynamics (CFD) modeling and economic analysis-the research offers a robust framework for designing commercial-capacity plants. The technical results confirm optimal gasification at an equivalence ratio (ER) of 0.35, yielding syngas with a calorific value of 5.38 MJ/Nm~3, gasification efficiency of 80 %, and net electrical efficiency of 15.9 %. Energy Return on Investment (EROI) values of 1.13 (net) and 1.59 (gross) underscore the system's energy performance. Economic viability was demonstrated with net present value (NPV) ranging from USD 5.6 to 7.8 million, internal rates of return (IRR) between 32 % and 38 %, and payback periods of 4.2-5.4 years. Sensitivity analysis revealed that the operational lifespan has a stronger impact on profitability than the performance degradation rate. The proposed configuration is particularly attractive in municipalities with fewer than 100,000 residents, where higher MSW disposal fees improve the financial case for RDF-based power systems. This work bridges the gap between pilot experimentation and practical implementation, contributing to the advancement of replicable waste-to-energy strategies aligned with the UN Sustainable Development Goals.
