Fungi-based insulation boards that absorb CO2, resist mold formation in walls developed

Researchers from Germany's Hof University of Applied Sciences have developed a new insulation material made from mushroom mycelium that captures CO2 and is compostable. The project, called Mycobuild, aims to produce these eco-friendly insulation boards at an industrial scale by 2026, using locally sourced plant residues. The material is tested for flexibility, moisture absorption, and thermal conductivity, showing promise in reducing mold risk through the integration of a mineral top layer. The team focuses on optimizing production while addressing consumer concerns about potential mold issues.
