Ferment
Research project to develop and test building insulation materials made from ensiled (anaerobically stored) plants, for use in the retrofit of buildings. November 2026 - July 2027
Having received funding from the Future Observatory at the Design Museum, we aim to unlock the potential of mixed plant by-products from food crops grown on regenerative farms – as an alternative to monocultural fibre, that competes with food systems for land.
The project will prototype production of fermented insulation in a Harvest-to-House system – accessible to farmers at all scales, using existing machinery, skills and infrastructure to supply local markets.
We hope to demonstrate the power of fermentation to provide a lower carbon, faster curing and stronger insulation product.
Ferment is follow-on research from our project Ag.Lab. that was completed in 2025, using grant funding from Ecological Citizen(s) Network+ (Royal College of Art).
Future Observatory is the Design Museum’s national hub for design research and the green transition. Established in partnership with the UKRI Arts & Humanities Research Council (AHRC) they act as a catalyst by supporting design research that can have real impact.
