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 is designing and financing a biomethane plant in the Gien commune in the Loiret department. The plant will be able to handle 28,500 tonnes of the region’s agricultural waste and biowaste, producing 250 Nm³/h of biomethane that will be injected into the GRDF network. The digestate produced will be used by partner farms as a substitute for conventional fertiliser.
