Pré estudo da viabilidade técnica e econômica do aproveitamento energético em um aterro sanitário de médio porte no estado do Ceará

Abstract

The main objective of this work was to study the technical and economic feasibility of biogas energy utilization in a medium sized landfill in the state of ceara. It happens in landfills, the phenomenon of anaerobic digestion with municcipal solid waste generating biogas. This biogas can be recovered and used to generate electricity. This case study comprises the analysis of biogas production, the sizing system used and an economic analysis. It was based on three scenarios of biogas production, and three scenarios for the sale of electricity were applied to these production scenarios. This method of analysis generated a basis for analysis of nine scenarios that demonstrated the economic viability of the model shows a sensibility to the selling price of electricity higher than the factors of production of biogas.
