Abstract: The use of fossil fuels has come along in recent years to foster a growing concern, not only related to environmental issues but also due to problems that the energy dependence from outside sources can cause to national economies. As an alternative to fossil fuels, many alternative energy sources have been studied, being the renewables those that have aroused most interest, especially due to its ecological character. In the field of renewable energy there are several forms to produce energy, being this variance the result of using different sources - wind, solar radiation, ocean waves, underground heat, dams or biomass. This diversification allows us to find solutions to the most varied needs, portending a future in which energy is produced from this mix of renewable energy solutions. The aim of this work was to study five different raw materials with potential use for the production of biogas through the process of anaerobic digestion. We used three agricultural substrates (oats, yellow lupine and oilseed radish) and two WWTP sludge (from fish and vegetables processing industry). The oats and yellow lupine produced about 400 m3 of CH4/ton SV, values very close to or even higher than those reported in the literature. The sludge from fish processing industry reached values close to 700 m3 of CH4/ton SV.
