GERAÇÃO DE ELETRICIDADE A PARTIR DO BIOGÁS DA ETE SÃO JOSÉ EM VARGINHA-MG: Análise do potencial e a viabilidade do aproveitamento

Abstract

This paper proposes an assessment of feasibility and potential of electricity generation from biogas of wastewater treatment plant (WWTP) São José in Varginha-MG. That approach was because the biogas produced in the studied plant being burned without producing electricity. This study wants to analyze feasibility for the energy use, leading to economical and environmental benefits to the city. That goal will be reached by a data survey of the WWTP to quantify the produced biogas and the cost of the infrastructure of this proposal. With the data, it’s possible to analyse economic and environmentally the proposed plant. The analysis resulted in the economic infeasibility of the proposed plant to the WWTP operator, part by the high costs of equipments and the unfavorable currency exchange, part by the low volume of biogas produced. Considering the CO2 emissions in comparison to the brazilian’s energy matrix emissions, this enterprise would led to a reduction of the emissions. This study is necessary in the future, because the city growth and reduction of currency exchange could bring different results.
