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.

260  Nm³/h of biomethane

One of the KEON Group’s flagship projects, this regional biomethane plant is equipped with several processing systems, which enable it to adapt to different feedstocks (manure, intermediate energy crops, animal by-products, etc.), producing 260 Nm³/h of biomethane. Working alongside regional farmers, TER’GREEN financed this plant, NASKEO built it, SYCOMORE is operating it and TEIKEI supplies it with feedstock. It’s a prime example of all of KEON’s subsidiaries working in synergy!
