There is an essential need for a change in the way we build our physical environment on all scales. Mycelium, a living fungal organism, is able to replace conventional materials, having the ability to act as a binding agent of natural fibers. Because all the components can be grown, this approach has no limitation by resources. In the form of a stool, Myomerge acts as a multi-layer biobased component and is able to carry a load beyond 20 times its weight. The product is fully biodegradable, hence fulfills the requirements of the circular economy.
