Sovereignty and Eco-Design: How a Basque Startup is Reinventing Advanced Composites with Cellulose
The global high-performance materials industry is undergoing a profound transformation, driven by the critical need to break away from fossil resources and high-carbon manufacturing footprints. While traditional composites are highly valued for their lightweight and robust properties in cutting-edge industries, they suffer from a heavy carbon footprint and recycling chains that are still in their infancy. Within this landscape of technological disruption, the Basque startup Aerboard is challenging manufacturing paradigms by converting an everyday resource, recycled cardboard, into an ultra-lightweight, exceptionally strong structural composite material.
The origin of this scientific innovation stems from an ingenious moment of improvisation during the global pandemic, when founder François Jaubert, a naval architect and engineer, faced a severe shortage of raw materials needed to build his own sporting equipment. By exploiting the physical properties of discarded cellulosic fibers and combining them with bio-based resins, he established the foundation for a patented technology capable of matching the mechanical performance of aluminum, wood, or traditional engineering plastics. Now operating from the Technocité hub in Bayonne, France, the company is drawing significant interest from diverse sectors including furniture design, luxury luggage, and aerospace engineering.
For the International Transition & Bioproduction Alliance (ITBA), the emergence of industrial solutions like Aerboard proves that bioproduction can meet the rigorous technical standards required by the most demanding global markets. One of the primary advantages of this technology lies in its entirely dry transformation process, which completely eliminates industrial water usage during material shaping. Furthermore, by optimizing the internal structure of the cellulose, the young company successfully controls a variable elasticity module, delivering a resistance to deformation superior to conventional plastics without suffering from the brittle failures typical of fossil-based composites. This dramatically cuts the carbon footprint, showing an environmental impact up to 95% lower than standard composite structures.
Beyond the technical and ecological achievement, this upcycling model provides a practical answer to contemporary industrial sovereignty challenges. Relying exclusively on local and 100% French raw material sources allows the supply chain to remain entirely independent of global geopolitical friction and petrochemical market volatility. This economic stability, paired with high-profile validation phases, such as prototyping structural aerospace components with the French National Centre for Space Studies (CNES), demonstrates that bio-based materials are no longer just laboratory concepts. Structuring these new industrial networks and establishing rigorous certification standards represent the next vital step toward normalizing high-performance cellulose on a global scale.
