Greensulate – Insulation from Mushrooms

In the very cool but very warm plant product category this week, we have Greensulate – a low-cost, rigid insulating board made from mushroom spores.

“The insulation is created by pouring a mixture of insulating particles, hydrogen peroxide, starch, and water into a panel mold. Mushroom cells are then injected into the mold, where they digest the starch producing a tightly meshed network of insulating particles and mycelium. The end result is an organic composite board that has a competitive R-Value a measurement of resistance to heat flow and can serve as a firewall.” (Thanks Sustainable Times)

Spores from oyster mushrooms are used in the board which according to David Blume can be grown on distillers grains. Another part of link in the permacultural chain? Corn – alcohol – distillers grains – oyster mushrooms – earthworms – castings – and insulation board? I may have to get one of these NZ oyster mushroom kits for Christmas.
