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.

EARL du Lac de Matefan is an organic pig farming business that already produces enough food and energy to be self-sufficient. Its biomethane plant was built with the aim of advancing this approach, recycling the effluents generated through animal husbandry and generating 160 kW of electricity. The biogas produced is converted into heat and electricity. The digestate is used to fertilise crop fields to produce feed for the animals. The heat produced is used to heat farrowing barns, a private residence, a gite and a swimming pool.
