ECIA Identifies New Opportunities for Circular Cellulose Insulation

Recent project results highlight opportunities to further strengthen circularity and resource efficiency across the cellulose insulation value chain.

One key development is the increasing use of recovered cardboard as a supplementary fibre source. As the availability of traditional newspaper feedstock continues to decline, cardboard offers a readily available and technically suitable alternative for insulation production.

The project also explored the potential of BioChar production from recycled cellulose insulation. This innovative end-of-life pathway enables long-term carbon storage while creating additional value from recovered insulation materials.

Together, these developments demonstrate how cellulose insulation can support resource-efficient construction through circular material flows and improved material utilisation throughout the building life cycle.

Looking Ahead

The combination of alternative recycled fibre sources and innovative end-of-life solutions provides a promising pathway for further strengthening the circular economy credentials of cellulose insulation and supporting the transition to a more sustainable built environment.
