Estudo da viabilidade econômica da geração de energia elétrica a partir do biogás: estudo de caso em criação de ovinos

Abstract

Energy is a fundamental resource for a country’s economic growth and human development. Taking this into account, it is fundamental to guarantee stability of energy offer, with reduced production costs and environmental impact. Distributed generation allows properties to generate their own electrical power, reducing their consumption through the grid. Biomass has been gaining participation in the internal supply of electrical power, since it uses as input environmental liabilities, leftovers from agriculture, to generate power. This study has as objective to analyze the economic viability of power generation using biogas created from sheep waste, aiming to meet the demand of a small property. It is an economical and environmental analisys based on literature and suppliers for different sheep flocks. It was shown that, to fulfill the power demand for the property being studied, would be necessary a herd of 140 animals.
