The present study is an analysis of the potential for energy recovery of municipal solid waste (MSW) and its consequent reduction in greenhouse gases (GHG) emissions. For the study, a daily production of 330 tons of MSW was considered and the generation of electric energy was evaluated through the incineration and methane recovery of a landfill. Methane generation was obtained using the LandGEM 3.02 model and the MSW LCV was calculated using the Dulong-Petit law. GHG emissions were estimated using the methodology proposed by UNFCCC (2018). Results showed that incineration would generate 77.500 MWh.year-1 of electricity and avoid the emission of 22.250 t CO2.year-1. Methane recovery would generate 23.500 MWh.year-1 of electricity and avoid the emission of 12.500 t CO2.year-1. Thus, in terms of energy recovery, incineration was more advantageous, however the choice of technologies involves, in addition to technical issues related to efficiency of the process, environmental, social, political and economic issues.
