    Recovery of recycled glass and carbon fibres into new recyclable composites

    RESITES is developing innovative solutions for the circular economy by means of technology that reuses carbon and glass dry fibre offcuts, which are materials that are usually discarded after the cutting processes in composite manufacturing.

    • The initiative transforms this industrial waste into high-performance technical materials, suitable for manufacturing advanced structural components.
    • This approach is an efficient alternative that reduces waste, cuts industrial costs and improves sustainability in composite material production.
    • One of the main benefits of the solution is the possibility of reintroducing textile fibre waste directly into the production cycle, so it does not end up in landfill.
    • The process has been designed to be easily implemented in the industrial facilities themselves, following the proximity principle, allowing for the treatment of offcuts right where they are generated.

    Unlike other composite waste, dry fibre offcuts do not show degradation

    These composite residues retain a high structural potential. As a result, the resulting materials are compatible with out-of-autoclave (OOA) manufacturing processes such as infusion or resin transfer moulding (RTM) – technologies that are widely used in the composite industry.

    The solution is also compatible with recyclable resin systems, including reversible-bonding thermoplastic and thermoset matrices, reinforcing the project’s commitment to more circular and sustainable industrial models.

    Strategic sectors such as aeronautics, automotive and wind power

    The technology is aimed at strategic sectors such as aeronautics, automotive and wind energy, as well as any industry that generates dry fibre trimmings waste and is looking to transform them into high value-added materials.

    With this breakthrough, RESITES demonstrates how innovation in composite materials can become a key tool to boost industrial sustainability and resource efficiency in Europe.
