Insoles made using mushroom spores are great for feet and the environment.
Now, Israeli students have produced an insulation material from mushroom cells that grow abundantly under the soil.
The lightweight material is made from mycelium and rapeseed straw that has been recovered from agricultural waste.
Then, the cultured fibre networks can be heated and pressed into blocks. The resultant construction material is both stronger than polystyrene and highly insulating.
Currently the team is working on using less heat in production, with the aim of eliminating CO2 emissions completely.
