Estimativa teórica de geração de biogás do futuro aterro sanitário da microrregião das chapadas do alto Itapecuru - MA

Abstract

Alternative energy sources are the main inducer of the world energy matrix based mainly on biofuels from Biomass. Biogas has in its composition carbon dioxide (CO2) and methane gas (CH4).  Resulting from the decomposition of organic matter, the study to be developed aims to evaluate the feasibility of using biodigesters for the energy use of biogas produced by the decomposition of organic matter from municipal solid waste, which contains a significant portion of biodegradable organic matter that goes through an anaerobic digestion process transforming garbage into clean energy. The study will be developed using as parameters the generation of waste in the municipalities that make up the Middle Sertão Maranhense having as methodological procedure, the application of the IPCC method. This method is generally applied to design landfill scenarios that are not yet operating. The present work seeks to contribute to scenarios in the face of discussions about the need to invest in alternative energies that minimize the current stage of greenhouse gas emissions, as well as to show the energy potential that this gas has and the possibility of transforming methane into useful energy, making biogas a profitable gas and mitigating the pollution problem. In total, the methane generated at the landfill in the 20-year period was 3,514,372.58 m³ CH4, generating an average of 175,718.62 m³ CH4/year.
