Abstract: Population growth has increased the production of municipal solid waste (MSW). The processes of degradation of MSW generate products poluants such as biogas. However, reforming biogas into biomethane for energy use can reduce impacts and increase energy supply. This study aimed to assess the technical and economic feasibility of using biomethane generated from landfills in the Southeastern region of Brazil to supply vehicles. The economic feasibility of this endeavor was verified using Net Present Value (NPV), and the Internal Rate of Return (IRR). We estimated Greenhouse Gas (GHG) emission reductions by replacing diesel with biomethane, using a methodology proposed by the Intergovernmental Panel on Climate Change. We analyzed 50 different landfill consortia. Consortia with installed capacity less than 5500 m³/day were economically unviable. The NPV ranged from around US$-20.00 million to US$120.00 million, while project IRR, with CAPEX from US$ 4 million, remains approximately constant, around 35%. Replacing diesel oil with biomethane produced can offset 29.14 trillion tons of CO2eq emissions. Biomethane is one option for replacing fossil fuels. This study is innovative because it presents an analysis of biomethane's energy and economic potential in southeastern Brazil, the country's most developed region, helping develop the national biomethane market.
