What You'll Learn
How is mushroom leather made?
Mushroom leather is an innovative, eco-friendly, and cruelty-free alternative to traditional leather. It is made from mycelium, the thread-like, dense cellular structure that forms the vegetative part of a fungus. Mycelium consists of a network of fine white filaments called hyphae, which can penetrate various substrates, including soil, wood, and organic matter.
The process of making mushroom leather begins with selecting and moisturising the right substrate to provide food that allows the mushrooms to thrive. Materials like corn, straw, wood chips, compost, and agricultural waste allow the mushrooms to attach to them so they can grow. Once the substrate is wet, it's placed into a bag and pasteurized. As the mushroom grows, the environment is primed to protect it against bacteria to promote faster, healthier growth of the mycelium. As the mycelium grows with plant fibres, it transforms into a flexible, soft textile similar to animal leather. The mycelium forms a sort of glue between the fibres to keep everything consistent and together. In most cases, the process takes about two to three weeks for the leather growth to complete.
Then, a mixture of water, starch, minerals, and hydrogen peroxide is poured into a mould and injected with living mushroom cells, and placed in a dark environment so the cells can grow. The mushroom cells digest the starch and form thousands of cellular strands that can grow to be one inch thick. The form is dried to prevent mould and it's now able to be used as leather. If the mushroom leather remains moist, it's more pliable and can be used for various applications.
The most common type of mycelium used in mushroom leather comes from commercial Oyster mushrooms. However, companies like Bolt Threads are experimenting with different types of fungi to obtain unique leather attributes. Their product, Mylo, is a supple yet durable material that has the potential to biodegrade and replace real and synthetic leather. It is grown by expert mushroom farmers in indoor vertical farming facilities and processed by scientists.
