Recent project results confirm the strong sustainability potential of cellulose insulation and highlight new opportunities to further strengthen circularity across the 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 continue to contribute to more sustainable construction by improving resource efficiency, supporting circular material flows and reducing the environmental impact of buildings over their 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.
