Feasibility of a novel use for agroindustrial biogas

For this mixture, maximum methane production reached has been 6.58 Nm3 methane/m3 substrate (mixture). According to those results, an AD plant has been designed. Biogas produced from this co-digestion would be used by local farmers to power motor pumps which would pump irrigation water. From the economic analysis we can deduce that the proposed biomethanisation plant is economically feasible, since there is a four year return on the investment if compared with the cost of the electricity consumed each year in the Regantes region.
