Features Flotate fats and oils from the food industry supply approximately 75% of the energy produced. The electricity generated in the biogas plant in Rohan is sold in its entirety to the energy company EDF. The generated heat is used by the agricultural firm Le Crom itself in order to heat the fermenter of the biogas plant. In addition, the company uses the exhaust heat to dry fermentation residues and to heat the flotate fats and oils from the food industry. Flotate fats and oils account for 75% and thus the majority of the energy produced at the plant, which is also generated from manure and maize silage. The agricultural firm has established long-term contracts with farming and industrial companies from the region, who supply much of the waste materials utilised by the plant.
Every farm or food enterprise generates by-products which are eminently suited to biogas production. The targeted utilisation of organic waste can help generate energy and heat. This lowers overall production costs and is also good for the environment. In short: what you would normally dispose of is a valuable source of energy.
