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 been commissioned by the French National Centre for Space Studies (CNES) to design and fund a biomethane plant in Guyana. This plant will be able to process 17,500 tonnes of agricultural waste and biowaste from the region and produce 800 tonnes of liquid biomethane that will be used to power a CNES space launcher and the local transport system. The digestate produced will be used by partner farms as a substitute for mineral fertiliser.
