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.


100% of projects we assist with come to fruition

From feasibility studies to securing feedstock sources, from financing to securing bank loans, from creating a watertight business plan to overseeing construction and, finally, operation, we work with you every step of the way to ensure the success of your biomethane project.

We are a French firm specialising in the co-development of and co-investment in biogas projects. Since 2018, our raison d’etre has been to provide support at every stage of your biomethane plant project, from inception through development to operation.

We help accelerate the project development phase

We specialise in the development of regional biomethane projects led by farmers, communities, manufacturers, semi-public companies and key players in the energy sector. We also collaborate on CNG/bio-CNG refuelling station, biogenic CO2 recovery, solar panel installation and self-consumption projects.

Take your project to the next level

We secure investment

From securing bank loans to strengthening capital funding and firming up business plans, we can help with every financial aspect of your project. Our experience combined with the trust-based relationships we have forged with key players in the biomethane industry make us the ideal partner in your project.

We optimise technical and economic performance

While designing, financing and building are the key stages in any biomethane plant project, the operation phase is equally important. That’s why, as project partners, we monitor day-to-day performance, providing expert advice and support, analysis and audits, operational assistance and business operation management tools.
