Making the Best out of Organic Waste - Biogaz du Pays de Château-Gontier
Every year, France produces about 350 million tons of organic waste. This waste comes mainly from agriculture, industry and municipalities. Several alternatives exist to reuse this waste and convert it into energy.

Biogaz du Pays de Château-Gontier is a methanization unit located in Mayenne near Laval, whose operation is based on the collaboration between the various local actors: a private operator (Evergaz), farmers, industrialists, and local authorities.
The plant recovers 35,000 tons of waste every year. It combines four modes of energy recovery: electricity, heat, bioGNV, and soon bio-methane. The site can process a range of 1,200 different types of waste, i.e. all the types of organic waste produced in the region.
Thanks to co-generation, the methanization unit supplies the equivalent of 3,200 homes with green electricity. Nearby, Evergaz has also built a bioNGV station open to the public, which supplies green fuel to the community's vehicles. Finally, the plant allows the spreading of natural fertilizer on the fields of 63 local farms.
