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.

A project led by TER’GREEN, the Grand Dole agglomeration community and 19 farmers, this biomethane plant was built by NASKEO and is operated by SYCOMORE. It processes almost 30,000 tonnes of organic waste every year, producing 25 GWh HHV of biomethane annually that is injected into the GRDF network. The digestate produced is used by the farmers who provide the feedstock. It’s a great example of regional synergies at work!
