TRATAMENTO E DISPOSIÇÃO FINAL DE RESÍDUOS SÓLIDOS URBANOS (RSU) COM VISTAS À GERAÇÃO DE ENERGIA: estudo de caso em usina termoquímica em fase de implantação em Boa Esperança - MG

Abstract

This work deals with the treatment and final destination of Solid Urban Waste in a practical case, resulting in the generation of energy, from a plant of Thermochemical Plant for the transformation of waste, being implemented in the municipality of Boa Esperança - MG. The technology used was raised, comparing it with the most used around the world, thus verifying its viability. Such an approach is necessary due to the need to solve the serious problem of final destination of Urban Solid Waste in Brazil and also to create alternative sources to the current energy matrix. The objective of this work is to analyze, through a practical study, if the use of the technique of Gasification by Fluidized Bed, used in the Plant of the Thermochemical Plant in implantation in the municipality, is viable when compared to some more used technologies, available for the transformation of MSW into energy. electric. This attempt was achieved through an exploratory research and a case study, carried out at the plant itself, which addressed the proposal for the implementation of the plant and an interview with the technician in charge. The research showed that the gasification technique, chosen for application in the plant of the Boa Esperança Thermochemical Plant, becomes the best technological route for treatment and final disposal of urban solid waste (MSW) with a view to energy generation (waste-to -energy) to meet the demands of the municipality, being able to solve the accumulated liabilities of Urban Solid Waste, this meeting the technical, economic, environmental, social and legal aspects involved.
