Aterros sanitários para geração de energia elétrica a partir da produção de biogás no Brasil: Comparação dos modelos LandGEM (EPA) e Biogás (Cetesb)

Abstract

Landfills for electricity generation from biogas production in Brazil: comparison of LandGEM (EPA) and Biogas (Cetesb) models Currently there is increasing concern about the environmental impacts generated by the production of solid waste, which helps to accelerate ongoing climate change. Solid wastes in landfills generate biogas as a product of anaerobic decomposition of organic compounds found in them. This research note estimates of the amount of biogas and energy generated by the anaerobic decomposition produced in a landfill in the city of Três Corações, Minas Gerais. To estimate these parameters, LandGEM (EPA) and BIOGAS (Cetesb) models were used. Both models showed similar results with a variation of only 5%. LandGEM model shows an accumulative biogas production of 26,075,960 m3, with an accumulated energy of 128.68 GWh and media power generation of 242 kW. BIOGAS model shows an accumulative biogas production of 27,476,360 m3, with an accumulated energy of 141.31 GWh, for an average power generation of 255 kW.
