摘要：

The potential energy uses of landfill gas (LFG) are investigated herein, focusing on electricity generation and leachate evaporation. LFG generation is estimated with the application of the GasSim method, using real data on the municipal solid waste disposal at the Metropolitan Sanitary Landfill of Joao Pessoa (Northeast Brazil). The results show significant LFG generation, with an estimated peak production of 11,277.28 t in 2028, and LFG generation until 2042. Commercially available biogas-operated equipment were analysed for electricity production in situ, considering production and operation restrictions at the landfill. It was verified that after 2018, a cogeneration facility can generate electricity and the available heat is sufficient to evaporate leachate. Positive net economic results are obtained, with an internal rate of return over 30% after 26 years, demonstrating that the cogeneration facility is profitable and self-sustainable.
