AVALIAÇÃO DO POTENCIAL METANOGÊNICO DE CHORUME GERADO EM ATERRO DE RESÍDUOS SÓLIDOS DOMICILIARES: O CASO DO CONSÓRCIO INTERMUNICIPAL DO PONTAL DO PARANAPANEMA (CIPP)

Abstract

Leachate is a liquid produced by the decomposition of organic and inorganic waste in landfills and can pollute soil and groundwater, as well as pose a risk to public health if not properly managed. In this work, the methanogenic potential of the leachate generated in the landfill of the Intermunicipal Consortium of Pontal do Paranapanema was evaluated to estimate the volume of biomethane produced from the leachate. Subsequently, an environmental and economic assessment was made of the potential replacement of diesel used by the waste collection fleets of the member municipalities of the consortium with biomethane. The results indicate that biomethane would supply 23.2% of the demand for fossil fuel, providing savings and a reduction in the amount of CO2 emitted into the atmosphere. This study demonstrated that the biomethane generated from landfill leachate can be an important source of renewable energy generation for the Intermunicipal Consortium of Pontal do Paranapanema to replace the diesel used by the waste collection fleets with biomethane.
