Our methanisation solutions
Methanisation is an energy recovery process whereby renewable gas is produced from organic waste. A virtuous technology that contributes to the ecological and energy transition, and at the same time encourages the circular economy. Explore our methanisation offers!
Working alongside you to make your methanisation projects a reality
Do you want to launch a methanisation project in agriculture, in industry, or within a local authority? We can support you and help you define your requirements to make the best technological and economic choices:
Choose your methaniser technology
There are two types of methanisation solution: dry or wet. Dry systems can accept a larger proportion of dry matter, whereas wet systems allow better mixing of the input material. We can offer you different solutions depending on your needs: what type of inputs do you want to recycle? What volumes? Are you aiming to use the gas you produce yourself, or is it for injection into the grid? We can advise you on the most suitable technological solutions for each project.
Finance and organise your project, alone or with partners
Our experts will support you in making the best preparations for your project, and will propose finance and co-finance solutions.
The solutions we offer
How does methanisation work?
Methanisation (or biomethanisation) uses the natural fermentation of certain waste matter to produce biogas. The raw materials used (or “inputs”) are organic waste from farming (manure, slurry, crop residues etc.), from agribusiness, or from local authorities (sewage sludge, household waste, cuttings from roadside verges etc.).
The process takes place within a methanisation unit: in a large tank, called a “digester”, the organic waste is heated and broken down by bacteria and micro-organisms in the absence of oxygen. This natural anaerobic digestion activity generates methane, a biogas that can be used directly to produce heat and electricity. It can also be injected into the natural gas grid to encourage the consumption of this renewable energy at a regional and national level. In this case, the biogas is purified so that its characteristics are similar to those of natural gas. This is referred to as “biomethane”.
Methanisation: a technology with many economic and ecological benefits
Energy recovery from waste
Through methanisation, organic waste becomes a valuable source of renewable energy. Methanisation also allows the recycling of fatty or very wet organic waste, which cannot be composted, and is thus a way of reducing the quantity of waste to be processed by other sectors.
A lever for the circular economy
Biogas and biomethane production can also be part of a circular economy approach, leading to many virtuous developments: local and non-relocatable energy production for local consumption, job creation, and a solution to the problem of managing household waste and agricultural co-products. It also enables agriculture to become more sustainable, generating additional income for farmers, and producing an alternative to synthetic fertilisers: the digestate, a coproduct from methanisation, is in fact a natural fertiliser.
An asset in achieving national and European energy decarbonisation targets
Methanisation allows the methane produced naturally by the breakdown of organic matter – particularly livestock effluents – to be captured and utilised. A valuable asset in the fight against greenhouse gas emissions!
Biogas and biomethane can also replace fossil fuels such as oil, coal and natural gas, because they can be transformed into heat, electricity or renewable fuel (BioNGV). According to “Methanisation in 10 questions” from Ademe, every kWh of biomethane injected into the gas grid could thus avoid 200 g of CO2 equivalent.
