Biomethane Generation Produced in Municipal Landfill

Abstract

Biogas emerged as a renewable technology that converts waste organic matter into energy. Among its components, in terms of energy, methane is the most important chemical composition, particularly for the combustion process in vehicle engines. The use of methane derived from organic matter residues in landfills to replace fossil fuel minimizes the environmental impact, providing a significant reduction in the emission of greenhouse effect gases,as does the use of the amount of urban waste generated by the population in a planned way, with a specific technological focus at the forefront of generating solutions for ecological, social, economic and management challenges, which are themes that characterize smart cities. Thus, this study is based on the investigation and analysis of the potential of biogas generated by the theMunicipal Landfill West of Caucaia (MLWC - AterroSanitário Municipal Oeste de Caucaia/CE (ASMOC))with the objective of estimating the amount of methane gas produced in the referred landfill, based on data already published related to the amount of solid waste disposed at the landfill and applying it in the Biogas - Energy Generation and Use Aterro(version 1.0) software, developed by the Environmental Company of the State of São Paulo (ECSSP - Companhia Ambiental do Estado de São Paulo (CETESB)).As main outcomes, it was found that the landfill can generate, between the years 2018 to 2034, more than 3 million m³of CH4, capable of supplying more than 201,362 vehicles fuel.
