Operating and maintaining

Since 2014, we have helped optimize the performance of biomethane plants. To do this, we offer services that leverage all operational drivers requiring concurrent management.



As organic waste experts, we bring together waste producers and short-circuit plants to recycle waste and benefit the country as a whole.

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/h.
