Landfills contain a large amount of organic matter, due to the deposition of residues in its cells. The decomposition of organic matter generates gases, such as methane, which is generated in large quantities and which is the main constituent responsible for the energy potential of biogas. To face the need to diversify the Brazilian energy matrix and to reduce the emission of greenhouse gases, the use of biogas may present some advantages. The objective of this study was to quantify the theoretical potential of the biogas energy utilization in the Sabará / MG landfill. For this, the methane gas generation during the life of the landfill was quantified. From this point, the power of power generation and the number of families that could be met with this energy potential were determined. The results show the landfill will produce in its 13th year about 510,316.52 m³ of methane, capable of generating a maximum power of 4,312.11 KW / year, serving around 19,674 families.
