Cap FilMI 2 Brique 1 : Un projet innovant pour l'industrialisation du miscanthus dans la Vallée de la Seine

The Cap FilMI 2 Brique 1 project is part of an ambitious initiative aimed at structuring and developing the miscanthus industry along the Seine corridor. Certified by three competitiveness clusters, including Polymeris, Next Move, and Cosmetic Valley, this project is a key step in establishing this industry in the region for the long term. Addiplast, a member of Polymeris, is also a partner in this innovative project, reinforcing its commitment to developing sustainable and bio-based solutions.

Project objectives

Cap FilMI 2 Brique 1 aims to regionalize the activities of the miscanthus industry, from upstream to downstream, in a pilot region: the Rouen Seine Eure metropolitan area. Building on previous successes, such as the Alkern Miscanthus Block and the Renault Dashboard, the project aims to:

Develop new multi-sector industrial bioproducts.
Integrate production and processing activities within a local ecosystem.
Identify new industrial outlets for miscanthus, particularly in green chemistry, cosmetics, and packaging.
Support farmers in diversifying their activities and offer them a sustainable source of income.

A structuring project for the region

The project focuses on the Gaillon Area, a 25 km territory around Gaillon, which has major advantages:

The presence of key industrial sites, such as Alkern Seine Eure for the production of miscanthus concrete blocks and Astradec Gaillon for pre-plastic processing.
The commitment of local elected officials and the mobilization of several hundred hectares of miscanthus to meet industrial needs.
A comprehensive and sustainable organization of activities, integrating farmers, logisticians, industrialists, and builders into a common structure (SCIC).

Environmental and economic issues

Miscanthus, a non-invasive and regenerative plant, plays a central role in the ecological transition thanks to its carbon storage properties, high yield, and lack of pesticides. The Cap FilMI 2 project also focuses on decarbonization of industry, the circular economy, protection of water resources, and the use of river transport for materials.

Outlook and impact

With the Alkern Seine Eure production unit scheduled to come online in 2025 and mass production of the first bioproducts set to begin in 2026, the project promises to have a significant economic impact. Industry estimates predict the manufacture of 3,000 houses per year and 4,000 tons of composites, requiring more than 400 hectares of miscanthus. These advances make it possible to envisage a viable economic model that can be exported to other areas of the Seine Valley by 2030.

Conclusion

Certified by Polymeris, Cap FilMI 2 Brique 1 is a flagship project for the industrialization of miscanthus, combining innovation, economic development, and respect for the environment. Thanks to close collaboration between farmers, manufacturers, and local authorities, this project is laying the foundations for a sustainable and promising industry for the future.
