A new vision, a new way, a new leather.

Sustainability 101

June 14, 2021

Innovation is incredible and here’s why. Mylo could be a break through for the future of leather. A material made from mycelium aka the renewable underground root systems of mushrooms, it is certified bio-based and can therefore be found in nature. This is great news, because it is a renewable material and will inevitably always regrow. Created using the principles of Green Chemistry, Mylo is designed to reduce any environmental impacts from start to finish. It is an example for how science is unique, fun and honestly just awesome. The mycelium used to make Mylo is grown from mulch, air, and water in just a few short week and the process starts with mycelium cells grown on beds of sawdust and other organic material. Next is when the most incredible things happen - billions of cells grow to form an interconnected 3D network (isn’t nature just amazing?!) which is then processed, tanned, and dyed to make Mylo.

Processing and finishing chemistries are evaluated and selected using Green Chemistry principles as well. The material is made by the company Bolt Threads, who not only take a comprehensive approach to the product life cycle including production inputs, energy and water use, and product end-of-life but also states that they excludes highly hazardous chemistries such as DMFa and chromium and unsustainable practices from the onset of product and process development. Nevertheless, the impact assessment of Mylo is at a preliminary stage, and Bolt Threads states that a full Life-cycle assessment (LCA) will be released in 2022, prior to large scale commercial rollout. It is so exciting that mycelium leather could be the material that will replace conventional leather in the fashion industry. This would considerably reduce the environmental and social impact associated with leather production. 

Fingers crossed for an eco-friendly, vegan Mylo leather future.
