What is mycelium?

You may have heard about mycelium in recent months as a sustainable alternative to leather and "pleather", with some brands trailing the material to create bags and shoes. But what exactly is it?

The fashion industry is still heavily reliant on petroleum-based materials like polyester, nylon, acrylic, and many others that are harmful to the planet. The production and consumption of these synthetic fibres generate greenhouse gas emissions, perpetuate the use of non-renewable resources, and release microplastics into the environment.

However, there are many exciting new innovations and promising alternatives that can replace traditional plastic-based fibres — like mycelium!

You may have heard about mycelium in recent months as a sustainable alternative to leather and “pleather”, with some brands trailing the material to create bags and shoes. But what exactly is it?

Mycelium is the vegetative or root-like structure of mushrooms. Growing mainly underground, it acts as nature’s recycler and communicator by taking leaf litter and wood debris and transforming them into mushrooms. Additionally, mycelium helps to supply nutrients and water to the plants in the forest while receiving vital sugars in return.

Known for its structural integrity and thermal insulation, mycelium can be grown and processed into an effective alternative to synthetic materials, making it a great bio-based, sustainable option for the fashion industry.

Our innovator Ecovative has successfully developed the technology to unlock the natural potential of mycelium, producing leather-like hides and technical foams that can be used in a wide range of applications, including fashion.

    Key findings from the Collaborative Ecovative Mycelium Pilot

    Leather production can have varying environmental impacts depending on the practices and standards employed. While some traditional leather is produced using responsible and sustainable methods, there are also growing concerns around its environmental footprint.  While there are multiple “vegan” leather alternatives available on the market, many of them contain synthetic materials, have worse performance metrics than conventional leather, or are not available at scale. These partly plastic materials cannot be recycled and fewer still are compostable. Alongside this, synthetic foams, often made from polyurethane, are made from petroleum, a non-renewable virgin resource.  There are lots of opportunities for innovation in both leather and foam alternatives: Ecovative’s petrochemical-free mycelium hides and foam alternative promises to be a more sustainable alternative, grown in a fraction of time compared to animal leather, and with minimal resources.

    The Untapped Agricultural Waste Project

    In February 2022, Fashion for Good started the ‘Untapped Agricultural Waste’ Project to validate and scale technologies capable of transforming agricultural residues into textile fibres. With catalytic funding from Laudes Foundation and collaboration from key industry partners such as adidas, Bestseller, PVH Corp., and Vivobarefoot, the project aims to reduce the negative impacts of burning agricultural waste, lessen dependence on virgin fibres, and foster the adoption of lower-impact alternatives.
