Current and prospective situation of municipal solid waste final disposal in Mexico: A spatio-temporal evaluation

Mexico, similarly to other developing countries, has planned landfilling as the central technology manage municipal solid waste (MSW). In this research, current and future situation of final disposal MSW in Mexico was studied, focusing on spatial temporal evaluation sites (FDS), landfill gas (LFG) emissions, potential power generation an 80-year horizon. Geographic information systems were applied for evaluation.
