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.

Built by NASKEO, this plant is kitted out with a biowaste deconditioning unit and is the product of a collaboration between agricultural businesses TER’GREEN and AOC développement. It will process around 20,000 tonnes of organic waste per year and generate 17 GWh HHV of biomethane injected into the GRDF grid. The digestate produced will be used on the plots of agricultural land owned by the project leaders.
