Methanation Methanation is a natural biological process for the oxygen-free decomposition of organic matter. Placing waste in an anaerobic environment enables decomposition of the organic matter to transform it into biogas and compost. Biovalis’s mastery of this process enables the company to meet the specific needs of local authorities that wish to reduce the impact of their waste while producing secondary energies. Have a look at the industrial methanation and composting unit set up at Lavigny (Switzerland). Have a look at the optimization works at the fermentable waste composting platform for the Puisaye joint syndicate in the Yonne department.
