This biological material is grown from mycelium, a fungal network of threadlike cells found in the root structure of fungi (think mushrooms). The mycelium is mixed with agricultural crop waste and then placed in a mould, where it digests the crop waste in less than a week, binding it into a structural material. The grown parts are then put through a dehydration and heat treating process that kills the mycelium. There are never any spores involved, and the finished product is just as dead as lumber.
It is used in packaging as a sustainable alternative to expanded plastics (e.g. polystyrene). Applications include packaging for furniture, wine bottles, and computers. It is being investigated for use for thermal insulation, car parts, and as a core material in sandwich panels.
The manufacturer can use a broad range of feedstocks to tweak the density, strength, texture, and appearance of the material. It can be composted in the garden. he sample is just one of several variants of the material. It is generally cost-competitive with expanded plastics depending on volume and application.
Use it for cushioning in disposable furniture for festivals.
The sample measures 90 mm x 90 mm x 20 mm. There is small hole in the sample where the information card is fixed.
