Shaping the future of the French biomethane industry
Commendations, Time for change, France
A leading project by: ARKEMA (France) Subcategory: Circularity and Climate neutrality
Arkema has undertaken an ambitious journey to reduce the carbon footprint of its bio-based high-performance materials. A major milestone of this initiative is a long-term agreement with ENGIE, started in January 2023. The agreement involves the supply of 300 GWh/year of renewable biomethane in France, marking it one of the largest private biomethane deals in Europe to date.
A Sustainable Supply Agreement

The collaboration between Arkema and ENGIE enables the production of advanced materials using renewable energy and raw materials, specifically castor seeds. These seeds are known for their minimal environmental impact, as they do not compete with food crops, do not cause illegal deforestation, and can be grown on marginal soils of low agricultural value.
This sustainable supply agreement significantly reduces the carbon footprint of Arkema’s bio-based polyamide 11 and elastomers.
Impact on Production and Carbon Emissions
Biomethane, a renewable alternative to natural gas, is produced through the fermentation of organic matter. In France, over 95% of the feedstock for biomethane comes from agricultural residues and organic waste, ensuring no competition with food resources.
The biomethane supplied by ENGIE is used in the production of Arkema’s bio-sourced polyamide. This renewable gas replaces fossil natural gas in the boilers at Arkema’s factory without requiring any modifications to the existing processes. Arkema’s Energy Purchasing department expects this development will lead to an annual reduction of 55,000 tonnes of carbon dioxide equivalent in the production of bio-sourced polyamide, further reducing its carbon footprint.
Historic Agreement
This agreement is historic not only in terms of its duration and the volumes involved but also in the care taken by both parties to optimise the conditions for producing this green energy. Biomethane emits around 40g CO2/kWh compared to 200-250g CO2/kWh for natural gas, highlighting its environmental benefits.
