Oudon Biogaz’s goal is to recover, in a sustainable manner, more than 140.000 tons of effluent produced in its 72 farms, 85% of which are composed of agricultural by-products such as slurry, manure and straw, to generate 55 GWh of biomethane per year, equivalent to the consumption of 9.000 families in the Craon area. Scraps of the cereals and local agri-industry by-products to feed the plant. The biogas produced will be put into the national grid and will avoid the emission into the atmosphere of about 14.000 tons of CO2, equivalent to the greenhouse gas emissions generated by 5.500 cars (with an average mileage of 20.000 km/year). The digestate will, on the other hand, be used in the 7.700 hectares of the fields of Oudon Biogaz farms, giving the opportunity to reduce the use of chemical fertilizers. The Oudon Biogaz plant will not only contribute 25% of biogas production in the Mayenne Department but will also create 10 jobs.
