How mushroom leather is made
Mushroom leather is a vegan-friendly and environmentally sustainable alternative to animal leather. It is made from mycelium, the vegetative part of a fungus that comprises the root structure of mushrooms. 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 pasteurised. As the mushroom grows, the environment is primed to protect it against bacteria to promote faster and healthier growth of the mycelium.
Mycelium grows by breaking down molecules like sugars in materials such as wood and plant waste and absorbing those smaller components. Its branched cellular structure gives mycelium a natural strength and durability, making it an effective alternative to leather. 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.
The most common type of mycelium used in mushroom leather comes from commercial Oyster mushrooms. However, companies like Bolt Threads and MycoWorks are experimenting with different types of mushrooms to obtain unique leather attributes. For example, MycoWorks uses reishi mushrooms, named after the Japanese name for the genus of mushrooms first used, to create a material that has the look and feel of leather. Bolt Threads' Mylo™ is another popular mushroom leather made from mycelium. It is supple yet durable and has the potential to biodegrade and replace real and synthetic leather. The material can be produced in days, significantly reducing its environmental impact.
