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.


Feedstock sources

40 000 tonnes per year



Cereal offal



285 Nm³/h of biomethane

Methavie is a regional project that brings together 19 agricultural businesses, two farming cooperatives (CAVAC and AGRIAL), industrial dairy Bonilait and the semi-public company Vendée Energie. An innovative flagship project in the Vendée department, it has injected 270 Nm³/h of methane and produced 2,800 tonnes of liquid biogenic CO2 per year since 2022. The plant processes 34,000 tonnes of manure, cereal offal and diethyl ether every year. It consists of two reception tanks for liquid feedstock, two digesters and two post-digesters, as well as storage for liquid digestate. The feedstock is prepared for the digestion process in a Fleximix system developed by Naskeo.
