Description: Mycelium is the vegetative part of a fungus, consisting of masses of branching hyphae. These fibres easily bind to other materials, especially those which are organic. Tŷ Syml has developed a number of processes that allow the mycelium to be combined with a variety of different substrates. As part of our business model, we have identified by-products from various industries such as wood chips, sawdust and brewers’ spent grain (BSG). By introducing mycelium we are able to transform these substrates into innovative materials within a period of 5 to 10 days. During this time period, the two elements (mycelium and substrate) fuse together to form a new material. The result of this process of combining mycelium with a substrate is the production of new materials that are surprisingly strong and lightweight. They are also 100% natural, can be recycled and are fully compostable.
