BioKnit: development of mycelium paste for use with permanent textile formwork

mycolabadmin

Researchers developed a new type of injectable mycelium paste combined with knitted fabric formwork to create lightweight, sustainable building materials. The BioKnit prototype demonstrates that this approach can produce large, complex structures like an arched dome using fungal material instead of traditional construction materials. The textile framework dramatically strengthens the mycelium composite while keeping the material environmentally friendly and relatively easy to produce.

Properties of Sound Absorption Composite Materials Developed Using Flax Fiber, Sphagnum Moss, Vermiculite, and Sapropel

mycolabadmin

Researchers created new environmentally friendly sound-absorbing panels using lake sediment (sapropel) as a binder mixed with natural fibers and minerals. These composite materials work well for reducing noise in buildings and have a decorative natural appearance. However, because they contain organic materials, they are susceptible to mold growth and need antimicrobial protection, with materials containing vermiculite performing better than those with moss.

Comparative Evaluation of Mechanical and Physical Properties of Mycelium Composite Boards Made from Lentinus sajor-caju with Various Ratios of Corn Husk and Sawdust

mycolabadmin

Researchers developed biodegradable composite boards using mushroom mycelium (Lentinus sajor-caju) grown on agricultural waste like corn husks and sawdust. By adjusting the ratio of these materials and board thickness, they created boards with properties comparable to commercial softboards and acoustic panels. These eco-friendly boards could replace synthetic materials in construction and furniture, reducing waste and pollution while maintaining good mechanical strength and sound absorption properties.

Development and Characterization of Mycelium-Based Composite Using Agro-Industrial Waste and Ganoderma lucidum as Insulating Material

mycolabadmin

Researchers developed an eco-friendly insulation material using mushroom mycelium (Ganoderma lucidum) combined with waste plant materials from Colombia: Arboloco pith and grass clippings. The resulting material is lightweight, thermally efficient, and comparable to commercial insulators like expanded polystyrene. However, the material shrinks significantly and absorbs water when exposed to moisture, so additional treatments are needed before it can be widely used in buildings.
