Mycelium-bound hemp/hay insulation panels as fossil-free alternative to EPS/XPS foam.
Mykor inoculates agricultural waste (hemp shiv, hay, brewery residue) with fungal mycelium that self-binds the substrate over ~4 weeks without synthetic adhesives, producing rigid insulation and partition panels. It directly addresses the embodied-carbon vs. regulatory conflict: incumbent petroleum foams (EPS, XPS, PUR) are carbon-intensive; emerging net-zero standards (Future Homes Standard, UKGBC) demand lower-carbon solutions, but bio-based alternatives lack thermal performance guarantees and regulatory approval. The product is at pilot scale (Portuguese facility operational, €4.6M raised 2025) with promising third-party impact ratings but incomplete certification.
Mykor inoculates agricultural and brewery waste with fungal mycelium that self-binds into rigid panels over approximately four weeks, producing insulation and partition elements without synthetic adhesives or petroleum-derived foam — directly targeting the embodied-carbon conflict at the heart of current energy efficiency regulation in the UK and Europe, where EPS, XPS, and PUR remain incumbent despite net-zero pressure. The €4.6M raised in 2025 and an operational Portuguese pilot facility give this more commercial traction than most mycelium material ventures, and UKGBC endorsement signals policy alignment. The fundamental performance gap, however, is that thermal conductivity and U-value data have not been publicly documented or independently verified: the core thermal claim that makes this a viable EPS/XPS replacement has not been made available for a specifier to evaluate, which is a significant omission at commercial readiness stage. Moisture sensitivity and long-term durability in wet or humid environments are also uncharacterised — mycelium-based materials can degrade, support secondary colonisation, or lose structural integrity under conditions that mineral and petroleum insulants tolerate — and current building regulation certification for multi-storey or structural use is incomplete. The four-week biological curing time creates manufacturing lead-time and inventory inflexibility that conventional foam extrusion does not impose. Mykor represents a credible direction in bio-based insulation and warrants engagement at the research and pilot specification stage, but a specifier cannot commit it to a U-value calculation or a regulatory compliance path until thermal performance data and Building Regulations certification are published.
Pilot production is real and funded (€4.6M 2025 round). UKGBC technical note and FirstPlanIt independent review confirm material recognition within UK AEC discourse. However, no published third-party EPD, CE mark, or thermal performance data (λ-value, U-value) is publicly accessible. Carbon-negative claims rest on biomass sequestration during growth but lack third-party verification. No confirmed building regulation approval for multi-storey structural use. Source webpage HTML is mostly JavaScript framework boilerplate, not substantive technical content. Durability, moisture sensitivity, and long-term structural integrity in real building conditions are not documented in accessible sources.
