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

30 000 tonnes per year


Manure / Liquid manure

Cereal offal



160  Nm³/h of biomethane

Methabraye is an innovative project that brings together 17 agricultural businesses. Processing 30,000 tonnes of feedstock each year, it purifies the biogas produced before liquefying and injecting the resulting biomethane at a site 17 km away. The liquefied biomethane is transported in a lorry equipped with a cryotank. Facts and figures:
• Processes 30,000 tonnes of organic waste a year, primarily livestock waste
• Works with 34 farmers
• Produces 135 Nm³/h of biomethane a year
• Generates 12 GWh a year, enough to power 1,000 households or 47 NGV (natural gas vehicle) buses
• Saves 2,800 tonnes of CO2 per year
