Energy potential and economic feasibility of biogas: case study of a landfill in Minas Gerais, Brazil

The final disposal of solid waste in landfills may result in the production of a clean and renewable energy through the exploitation of biogas generated in these locations. This study aims to estimate the methane production in a landfill, with a total population of 237,298 inhabitants, and a total g...
