As a result of the increasing global energy demand and the negative environmental effects associated to the use of fossil fuels, the interest in alternative and more sustainable energy sources is growing. This research study processes of energetic conversion of municipal solid wastes to produce electrical and thermal energy or biomethane. A technical and economical analysis of anaerobic digestion plant is carried out after the characterization of wastes through the measures of total solids and organic substances. Municipal solid wastes such as, with wood cellulosic with biocell are analyzed, obtaining values of total solids equal to 37.81�±9.66 g, 59.26�±9.07 g, 50.13�±18.24 g respectively; values of organic substances are respectively equal to 87.62�±4.43 g, 89.74�±0.82 g, 83.03�±12.03 g. Pro II software simulation is used: The anaerobic digestion occurs at 328 K with a volume equal to 1300 m3 and a residence time of 24 days. Results suggest that with 20000 t/year of feed the plant can produce 2660 MWh/year of electrical energy, 1670 MWh/year of thermal energy and 2136000 m3/year of biogas at 62% of CH4. The VAN is 1690000 â�¬ and ROI of 6 years: Due to the economical incentives the plant is economical feasibility. Removing the CO2 from biogas, the plant can produce 695200 kg/year of biomethane for the immission in the network at the same condition. The VAN is 2960000 â�¬ and ROI of 5 years. Future researches should be about the study of new configurations of the plant to optimize the production of biogas and biomethane.
