Mykofoam is a type of rigid insulation developed by Mykor, made from mycelium the root structure of fungi. It is formed by naturally binding mycelium to waste materials generated by paper and pulp production. This unique insulation is not only renewable and bio-based, but also boasts a manufacturing process that has a negative impact on carbon emissions. In addition to its environmental benefits, Mykofoam has excellent thermal and acoustic properties, making it a highly effective insulation material.
Current status of the market and challenges
Fires like Grenfell and in Valencia have pushed customers away from flammable plastic insulation. Although mineral wool is safer, it has high embodied carbon and relies on non-renewable materials for its production. The market lacks affordable, high-performance, low-carbon alternatives.
The insulation market is made 55% plastic materials and 37% mineral wool, both with drawbacks. Mykofoam offers a superior thermal performance, fire resistance, and affordability. Derived from waste feedstock, it reduces energy costs and enhances living conditions. Strong partnerships with manufacturing construction companies ensure market reach, setting Mykor apart from competitors lacking distribution networks.
If Mykofoam captured 5% of the EU market it could provide insulation panels for roughly 50,000 homes, both new builds and renovations alike. This would divert 250,000 tons of biomass from incineration.
In Portugal, for instance, using Mykofoam in a 1002 home could lead to energy savings of 535 EUR per year compared to a non-insulated building. The total payback period for the investment would be just 10 years.
What is the INBUILT project doing to enhance MykoFoam?
The INBUILT project is enhancing thermal performance of the Mykofoam. Durability and moisture absorption have also improved through successful coating formulations. A life cycle analysis is underway, supporting environmental sustainability efforts. The target Technology Readiness Level (TRL) is 8, reflecting significant progress toward market readiness.
How will the Mykofoam be tested?
Mykofoam will be tested as insulation in two demo sites. In the transportable tiny houses (Germany), 50mm boards will be applied externally to assess insulation, breathability, moisture absorption, and durability. In the Historic Industrial Building (Birmingham, UK) 100mm boards will serve as the sole insulation, also testing acoustics.
The final objective is to achieve a 35% to 55% reduction in energy demand compared to the building's energy consumption pre-renovation.
