Cutting the Carbon from Insulation Cellulose-Mycelium Composite Material
The National Renewable Energy Laboratory (NREL) will develop a cost-effective, easy-to-fabricate bio-based insulation from celium (a cellulose-mycelium composite) to reduce the embodied and operational CO2 footprint of new and retrofitted residential housing. NREL will create celium by valorizing cellulose with mycelium, the root network of fungi, to create a new class of high-performing, carbon-capturing and -storing textiles, foams, and composites. The team will fabricate a net CO2 negative celium material with high-performance thermal, acoustic, and antimicrobial properties. They will move the material from lab to market by improving the manufacturing process to allow local fabrication of construction materials using local materials and expertise, further lowering the CO2 footprint of buildings.
HESTIA projects will facilitate the use of carbon storing materials in building construction to achieve net carbon negativity by optimizing material chemistries and matrices, manufacturing, and whole-building designs in a cost-effective manner.
