Co-development of and co-investment in biomethane projects

Drawing on many years' experience, we help you develop your projects, from compliance with the relevant regulations right through to operation.


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.
