Description
Summary:This study aims to evaluate the potential of energy use by in MSW landfill sites by considering the use of landfill gas and solar photovoltaic system, through a case study. In the case of photovoltaic solar energy, it is considered that the system would be installed on the top deck of the landfill. For a Brazilian case study in a landfill consortium in Itajubá, south of the Minas Gerais’ State, the landfill gas generation was calculated using the LandGem ® software. The optimum power and generator number for thermal power plant were obtained by a staggered method. The energy potential of a solar photovoltaic plant at this landfill was calculated using the PVSyst ® software. During the considered periods, the analyses show that the two systems presented economic viability. There are positive effects when they are benefited as mini- and micro-distributed generation systems as preconized by the Brazilian National Electric Energy Resolution no. 482/2012 updated by the Resolution no. 687/2015. The biogas system could generate a total of 162.1 GWh for 30 years, and the solar system 15.1 GWh for 25 years of operation.
