Biogaz du Pays de Château-Gontier
Biogaz du Pays de Château-Gontier is an anaerobic digestion unit located in the industrial zone of Pays de Château-Gontier in the Mayenne department (53). With its 4 forms of energy recovery - green electricity, green heat, bioNGV and now biomethane - the unit is a perfect example of circular economy. It recovers the organic matter produced locally by farmers, agri-food industries or the community. It supplies the equivalent of 1,700 homes with green electricity, for a treatment capacity of 35,000 tonnes of waste per year.
Project description
The facility forms part of the local economic fabric of the Azé industrial park where it is located. The unit is supplied by approximately forty farms, agri-food waste collectors and two local industrial companies: an abattoir and a cheese dairy which uses the heat generated. Evergaz built an NGV and bioNGV station open to the public in direct proximity to the biogas facility.
