Circular-C Kick-Off Meeting June 2025

New Horizon Europe project CIRCULAR-C Kicked off: Novel biobased formulations for CIRCULAR Construction materials

Major Barriers to Wood Fiber Recycling – Adhesive Contamination as Primary Obstacle

The scientific literature continually identifies adhesive residues as the main contaminant preventing effective wood fibre recycling. Urea-formaldehyde adhesives, which represent the prevailing binding system, create multiple recycling challenges such as cross-linked polymer networks and particle quality degradation as well as chemical contamination issues. This significantly complicates the recycling process, since up to 60% of collected wood waste consists of physical and chemical impurities.

A new generation of circular chemicals

The CIRCULAR-C project will focus on developing a new generation of circular, sustainable, and biobased adhesives, coatings, and functionalized fibres. Designed specifically for wood panels, which are commonly used in flooring, furniture and insulation, these innovative formulations will feature reversible chemical bonds and fire retardancy. This approach enhances recyclability and significantly reduces environmental impact, paving the way for a more sustainable and circular construction industry. An integral part will be the inclusion of Digital Product Passports (DPPs). The development will follow the Safe and Sustainable by Design (SSbD) principles and include environmental safety and life cycle assessments. As the project name suggests, the focus of the CIRCULAR-C project is on circularity throughout the whole life cycle. Therefore, investigation of recycling and secondary recycling as well as secondary market applications are included in the project. Through these efforts, CIRCULAR-C is aiming at increasing the capacity of biobased sectors by maximizing residue valorisation and material recycling, as well as minimizing environmental and climate impact.

Kick off in Alkmaar, Netherlands

On 17 and 18 June 2025, the Circular-C consortium, came together at the project’s kick-off event in Alkmaar, Netherlands, hosted by TNO, to launch the project’s activities. The project, funded by the EU’s key funding programme for research an innovation, Horizon Europe, will run for 48 months and be coordinated by the Belgian research organization VITO. The Steinbeis Europa Zentrum will contribute with its expertise on project communication, dissemination, exploitation and stakeholder engagement and lead the respective work package.

The project consortium is composed of ten partners from seven European countries.
