06 May BBI Call for proposal : Develop biobased solutions to recycle composites

The Bio-based Industries Joint-Undertaking (BBI JU) is a EUR 3.7 billion public-private partnership between the European Union and the Bio-Based Industries Consortium (BIC). Operating within the framework of Horizon 2020, this EU body is driven by the vision and strategic innovation and research agenda (SIRA) developed by industry.

In the 2020 annual work plan, a call related to composites was launched: “Develop biobased solutions to recycle composites“.

Specific Challenge

The full recyclability of composites through the effective separation and recovery of their components is still an issue. This is mainly due to the adhesives used to bind the different layers and materials together. The fossil-based bonding components that are currently used cannot easily be separated from the other components, nor can they be recycled together with the matrix material.

Industry can improve the recyclability of composites by designing bio-based bonding materials that will decompose under specific conditions (e.g. pH, temperature, microorganisms). These new bonding materials will replace fossil-based counterparts in composites and allow multilayer plastics and composites to be recycled more easily.

A useful concept when considering recyclability is ‘extended producer responsibility’ (EPR). EPR makes manufacturers of composites – or any product – responsible for the entire life cycle of the product, especially for the take-back, recycling and final disposal. EPR is crucial for creating a sustainable and circular bioeconomy. EPR will be an important input to some quickly expanding application areas, such as 3D printing of cellulose-based materials, which offers new opportunities for regional industries.

The specific challenge is to increase the recyclability of composites.
