Abstract
Urban solid waste (USW) destined for landfills produces garbage gas from anaerobic decomposition, which is an excellent source of energy with a high lower heating value (LHV). The objective of this article is to quantify the generation of methane in biogas and to estimate the production of electric energy utilizing internal combustion engines (SI) for the landfill in Marituba, in Pará. Utilizing three methodologies of biogas: LandGEM, IPCC, and Cetesb, to obtain greater accuracy in the results. Methane production, from 2015 to 2025, was estimated at 58.4 107 m3 using the IPCC methodology, 37.1 107 m3 of CH4 using the LandGEM methodology, and 29.2 107 m3 of CH4 using the Cetesb methodology. For generation bioenergy utilized 60% of CH4 and the efficiency of SI medium value 28.6%. Through the Cetesb result, approximately 20.93% of the population of the city of Marituba can be served with electricity in 2021, by the LandGEM methodology, approximately 26.37% of the Marituba’s population in the year 2021 and by the IPCC methodology, approximately 43.04% of the population of Marituba. Through the results, the present study demonstrates the importance of the use of USW to bioenergy production, in addition to the great energy potential of the landfill.
