Solid waste management is a problem in Costa Rica.Multiple solutions have been proposed, but the Costa Rican lifestyle requires more efficient methods and less environmental impact.This work evaluated incineration, gasification, plasma gasification, and pyrolysis as energy generation solutions for solid waste in Costa Rica.We used quantitative and qualitative criteria to compare the methods, including economic, energy, environmental elements, solid waste management, and technology maturity.In cases where it was not possible to establish a direct relationship or comparison, we established an indirect relationship or comparative based on information between technologies.Plasma gasification had the optimal results in power generation capacity, applicability of available waste, and caloric value.Additionally, the plant required the lowest installation area, with few emissions of pollutants to the environment, and the best in terms of waste-reducing capacity, the latter being a notable characteristic that puts it first to the problem and solution in the elimination of the landfills and landfills.This would release large land extensions, in addition to the great benefit of relieving the environment of large amounts of waste that would take many years to disintegrate.
