Scientists at Newcastle University in the UK are exploring the use of fungal networks, known as mycelium, to construct buildings that are lighter and more environmentally friendly than those made with concrete. Mycelium, which are small strings that form part of a fungus, intertwine underground with tree roots, creating a network through which plants can share water and nutrients. Researchers are harnessing the growth properties of mycelium to develop a substance called mycocrete, a paste that, when dried, is stronger and more versatile than other biomaterials derived from fungi. The process involves mixing mycelium spores with materials that the spores can grow on, such as grains, and placing the mixture in a warm, dark, and humid environment until the mycelium forms and dries into a building material. The team at Newcastle University has improved this process by using flexible, tube-shaped knitted molds, which allow for more oxygen to enter and facilitate the creation of mycocrete. Their innovative construction technique was demonstrated through the creation of a freestanding dome called BioKnit, which was tested for strength and outperformed previous samples. The potential impact of using mycelium as a replacement for concrete is significant, as concrete is the most consumed product on Earth and its production contributes to 4.4 billion tons of air pollution annually. However, further research is needed to develop the right mycelium mix for widespread use in construction.
