Biogaz des Vieilles Vignes is a France-based renewable gas company focused on producing biomethane from agricultural and other organic residues via anaerobic digestion. The biogas is upgraded to grid-quality biomethane for injection into the natural gas network or for use as a low-carbon fuel.
Its operations link agriculture with the energy and chemical value chains by converting local biomass into renewable gas and returning nutrient-rich digestate to fields. The company contributes to circular economy goals, greenhouse gas reduction, and the reliable supply of renewable gas for heat, power, mobility, and industrial applications.
The 40th EnviThan plant in France processes 100 tonnes of agricultural residues daily, feeding biomethane into the local grid. A new plant in Montans is set for 2026.
