Startup Dossier
CGREEN
Nantes-based startup developing biosourced, low-carbon carbon fiber made from cellulose — a renewable, local, and abundant resource. The company’s innovation reduces the CO₂ footprint of conventional petro-based carbon fiber by a factor of three while maintaining equivalent mechanical performance. Originating from a decade of R&D under the FORCE project led by IRT Jules Verne and supported by Forvia, CGREEN aims to industrialize a French biosourced carbon fiber sector to strengthen industrial sovereignty in strategic materials.
