Evaluación técnico-económica y ambiental de una planta de gasificación de residuos sólidos municipales para la producción de electricidad en la ciudad de Sincelejo, Colombia

In this work, the technical-economic and environmental viability of a municipal solid waste (MSW) gasification plant for the production of electricity in Sincelejo, Colombia was investigated. The study was carried out using a model implemented in Aspen plus, which allowed obtaining material and energy balances, essential for the calculation of technical, economic and environmental indicators. The economic calculations were carried out following the methodology established by Peters & Timmerhaus. Different types of MSW were considered including food waste, wood, paper and cardboard residues, as well as pruning and garden remains. Two waste utilization scenarios were evaluated: scenario 1, with 69% utilization and scenario 2, with 34% utilization. The results revealed that the overall efficiency of the process was 14.3% and an energy resource efficiency of 49%. Both scenarios present technical feasibility, however, the differences in their scales, 167 t/day in scenario 1 versus 85 t/day in scenario 2, impacted the viability of the project and operating costs. Scenario 1 presents significant economic viability, with a positive NPV and a favorable IRR, attributable to its larger scale of operation. In contrast, while Scenario 2 is not economically favorable. In both cases, without subsidies or incentives, the projects are unviable. In conclusion, both scenarios represent a clean solution for waste treatment, significantly reducing CO₂e emissions compared to landfilling, highlighting the importance of sustainable policies and advanced technologies for waste management.
