Spotted: Construction and demolition is responsible for more than a third of overall waste in the European Union. But now, British company Biohm is reducing this waste by helping the construction industry shift to a circular model.
The startup’s first product is insulation made from mycelium, the thread-like roots of fungi. The material is not only biodegradable, but outperforms typical foam insulation, having less thermal conductivity. It is also slower to burn than other types of insulation and, importantly, it can be composted at the end of its life and used to grow more insulation.
Biohm grows its mycelium by feeding it agricultural and food waste, making the final product carbon negative. The insulation is grown in the shape of a standard panel, then cured to form a strong and rigid material. This approach completely avoids the use of toxic chemicals and fossil fuels and the panels do not produce harmful dust when cut.
Springwise has spotted mycelium being used to replace other materials, including in fireproof building cladding, packaging, and even clothes.
