Composite materials are widely used in various growth sectors of the cross-border region: transportation, sports, sanitation, wind power and aeronautics. These materials are made of a polymer matrix (thermoplastic or thermosetting) and reinforcing fibres (glass, carbon, natural fibres). Their recycling is a cross-border problem due to the fragmentation of a sector essentially composed of SMEs. It therefore consists of a major challenge in the context of a European transition towards a circular economy for the effective use of resources and a reduction in environmental impact throughout their life cycle. Hence, the RECY-COMPOSITE project aims to respond to the challenge of recycling composite materials with an overall cross-border approach on three levels: material recycling, thermochemical recycling and energy recovery only as a last resort. Applied research will be conducted both for waste from the production of thermoset composites and end-of-life composite materials, and will aim to improve the life cycle of these materials. This integrated and innovative cross-border approach is made possible by pooling the complementary skills of the six partners to cover the recycling loop of the composite materials and thus respond to the needs of the companies in the area.
