METHANIZATION
The Design Office in Vannes
In the heart of the Gulf of Morbihan, an enthusiastic and experienced team is committed to offering cutting-edge technical solutions adapted to your needs.
​
Our ambition? Intelligently and confidently bring to fruition projects that meet the ecological and economic challenges of the future.
A solution for every situation
Methanization is an anaerobic process for transforming organic residues and waste into decarbonized and renewable energy (biogas) while producing a green fertilizer intended to enrich the soil and promote crop development.
Liquid methanization
We are particularly targeting a clientele of communities, developers and agricultural groups with projects exceeding 18GWh/year of energy.
Liquid digestion technology is recommended for deposits with limited sediment and floating matter and where the mix to be treated tends to be slightly dry.
With a drawer offer ranging from the process brick to a turnkey unit, we will be able to support you at each phase of your project, guaranteeing efficiency, performance and reliability.
With the support of our manufacturing workshops and our own assembly and automation teams, we can guarantee responsiveness and adaptability during the construction, commissioning and operating phases.

Methanization in the pasty piston flow process
Continuous dry or pasty methanization technology was developed in the 1980s to recover energy from local authority deposits (green waste and FFOM).
Building on its success, the patented METHAVOS digester is aimed not only at local authorities but also at territorial projects or agricultural groups with straw and dry deposits.
With a drawer offer ranging from the process brick to a turnkey unit, we will be able to support you at each phase of your project, guaranteeing efficiency, performance and reliability.
The strengths of METHAVOS patented technology
Steel construction system integrating an external heating solution to the media. Reduced on-site implementation time, stability and sealing of the structure over time and no risk of crusting on the heating network.
Digester sizes ranging from 1500 to 2100 m3 for a production capacity of 400 to 560 Nm3 Biogas/hour.
Controllable multi-zone slow agitation. Low energy consumption, resilience of the solution in the event of an agitator stopping, no maintenance related to agitator wear.
No sedimentation or flotation of material. No cleaning required throughout its operation.
Continuous operation, mesophilic or thermophilic regime.
Very short stay times (between 17 and 25 days).
External mixing before introduction by piston pump or transfer screw guaranteeing good homogeneity of the media.
Very favorable water balance (minimization of liquid digestate).
