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.

200 Nm³/h of biomethane

This communal project brings together 25 farming businesses and CYCLAD, a waste processing union in the Charente-Maritime department. It processes 34,000 tonnes of effluents, agricultural and agri-food industry co-products each year. The biogas is converted into biomethane then injected every year at a rate of 215 Nm³/h. Following liquefaction, the CO2 produced is also reused and the digestate is spread over 1,600 hectares of farm land.
