Estudo da viabilidade econômica do aproveitamento do biogás produzido no aterro sanitário de Foz do Iguaçu–PR como fonte de energia elétrica

Abstract

The final disposition of urban solid residue in sanitary landfill is one way to destination less impactful and more environmentally suitable to discard the residue. Although this alternative reduce considerably the environment problems occasioned by the inappropriate disposition of residue, the microbiological degradation of organic matter produce hight ratter of pollutants gases emission, in special the methane gas. In this context, the methane energetic use in sanitary landfill can show a economic and environment solution, once, besides avoiding the air pollution can also serve the local energy demands. Thus, the study objective was made an analysis of the economic viability of the energetic biogas use generated in the Foz do Iguaçu – PR sanitary landfill. Using the Intergovernmental Panel on Climate Change IPCC 1996 methodology to estimate the potential of methane emission of 2001 to 2010, and the method of project to estimate the generating biogas after closing the cell, also it was accomplished the sizing and the costs the implantation of the catchent system and the energetic biogas use. Based in this results, the analysis of the economic viability of the project was made using this criterions: payback, VPL and TIR, showing that to the landfill in study is uneconomical and environment feasible to carry out the energetic biogas use, once the technology costs of the use are very hight.
