Permafungi SA is a Belgian circular bio-manufacturing enterprise founded in 2014, operating an industrial-scale myco-materials manufacturing facility located in Forest (Brussels). Originally started in underground urban agriculture growing mushrooms on spent coffee grounds, the company expanded into industrial bio-materials to replace polystyrene and petrochemically derived solids.
Permafungi cultivates mycelium on organic residues, primarily local sawdust sourced from Belgian sawmills. The mycelial network colonizes the substrate within custom molds to grow solid, biodegradable 3D structures that are water- and fire-resistant, emitting ten times less CO2 and consuming eight times less energy than expanded polystyrene.
The company provides custom-engineered bio-packaging, interior acoustic panels, and design objects for European luxury brands, hospitality chains, and industrial clients.
