Owens Corning, one of the largest manufacturer of fiberglass composites, and Gjenkraft AS a recycling company based in Norway, have entered into a strategic collaboration to accelerate circular economy initiatives within the composites industry. This partnership underscores the composites industry s transition toward sustainable manufacturing models, where innovation in recycling processes becomes a core enabler of future growth.

The two companies have signed a Letter of Intent (LOI) to jointly develop scalable solutions for recycling post-industrial composite waste, aiming to transform end-of-life materials into valuable secondary raw inputs for new composite production.

Through this partnership, Owens Corning aims to incorporate recycled glass fibers produced via Gjenkraft s advanced thermolysis-based recycling process back into its glass fiber manufacturing. This closed-loop model seeks to demonstrate how high-performance composite waste can be reprocessed and reintroduced into industrial applications, reducing both landfill dependency and carbon emissions.

This marks a significant step toward industrial circularity in the glass fiber sector. It reflects the growing demand from manufacturers and regulators for sustainable materials with verified recycled content. Owens Corning s commitment to integrating recovered glass fibers aligns with its broader sustainability objectives, advancing resource efficiency, lowering the environmental footprint, and enhancing the recyclability of composite products.

Gjenkraft s proprietary thermolysis technology enables the recovery of glass fibers and other valuable constituents from composite waste streams, providing a practical and scalable route for circular composite production. The collaboration with Owens Corning validates the potential of Gjenkraft s process to operate at industrial scale, ensuring both economic and environmental viability.
