Researchers at the University of Kassel in Germany developed a method to make a wood mycelium composite construction for CO2-neutral, circular interior fittings for office spaces.

Mycelium is the root system of mushrooms. It can be grown in virtually any shape and has similar properties as polystyrene, yet is biodegradable. The material grows on plant-waste like coffee grounds or agricultural waste and has been used in anything from packaging material to insulation and acoustic solutions. However, non-reinforced mycelium-based materials have a low load-beading capacity.

The researchers in Kassel developed an automated glueless process to efficiently create 3D lattice structures from indigenous maple wood. This wood serves as reinforcement and moulding scaffolds for the mycelium to grown on. The wood ensures the composite’s load-bearing capacities.

The aim of the project was to create CO2 neutral, circular fittings to upgrade existing office buildings.
