TER’GREEN has joined forces with a farmer in the Drôme department and the semi-public company ROVALER to design and co-finance the BIOTEPPES biomethane plant. The plant will be supplied with agricultural feedstock, including manure, intermediate energy crops and cereal offal. The plant is expected to be operational in March 2024. The biomethane produced will be injected into the GRDF network at a flow rate of around 90 Nm³ CH₄/h.
