We design and build your project working alongside you
Our design team provides support at the administrative and development stages of your biomethane project, from feasibility studies right through to the final connections, including help with compiling administrative and financial documents.
Our injection and cogeneration technologies
We specialise in the design, build and commissioning of biomethane plants. We adapt our solutions to the different feedstocks you use in order to optimise the performance of your future plant and ensure ease of operation. We can set up different processes including continuous stirred or wet digesters and dry digesters, as well as offering different biogas recovery methods such as biomethane injection and cogeneration.
Our latest projects
Located in the Fontrailles commune in the Hautes-Pyrénées department, the Pays de Trie Agrogaz biomethane plant produces 310 Nm³/h of injectable biomethane from biogas. Led by a group of 72 farmers, Agrogaz company shareholders, the plant processes 70,000 tonnes of feedstock consisting mainly of livestock manure. In addition to injecting biomethane into the GRDF network, it also produces reusable biogenic CO2 thanks to a purification system. 4789Households supplied with gas 112Gas-powered buses
Led by a group of farmers, the OCEALIA cooperative, Zoo de la Palmyre and TER’GREEN, the collective Agri-Seudre Énergies project processes 20,000 tonnes of agricultural feedstock (manure, vegetation cover silage and cereal waste). A prime example of a successful regional project, the plant produces 150 Nm³/h of biomethane.Find out more 2177Households supplied with gas 51Gas-powered buses
Located in the foothills of the Pyrenees, this plant was founded by a group of four farmers and processes 20,000 tonnes of effluents and crop residues every year. The biogas is cleaned to create biomethane, which is injected into the GRDF network. Find out more 1741Households supplied with gas 41Gas-powered buses
