TECHNOLOGY ASSESSMENT

Mycelium Leather Technology Assessment

You know that mushrooms have been a food source for centuries. These days, their use in building materials and as packaging is replacing plastics in a sustainable way. MII is particularly excited about growing mycelium as animal-free leather. For this technology assessment, we went underground for the real story of how the roots of mushrooms can change the way leather is made. 

LEARN ABOUT NEXT GEN SILK TECHNOLOGY

Decoding Nature's High-Performance Fiber with Alex Connor

Are you curious about how scientists are working on developing replacements for silk in the lab? In this presentation, Alex Connor, a PhD student in chemical and biological engineering at Rensselaer Polytechnic Institute explains in a very approachable and digestible way what silk is by looking at its components, including amino acids, peptides, and proteins, and then how the silk proteins can be replicated through non-animal sources into fibrils, fibers, and then woven fabrics. He also explains why industry is trying to replicate silk. Silk is such a unique fiber with high tensile strength, elasticity, and toughness and well as being lightweight, biocompatible, temperature stable, and completely biodegradable. It also has significant negative attributes such as killing trillions of silkworms per year and having the most negative environmental impact out of all materials used in the fashion industry. A handful of companies have already developed next gen silk materials which do not use animals and are more sustainable. 

MATERIAL TESTING REPORTS

Material Performance and Sourcing: Bovine Leather

In order to replace leather, we need to know what makes leather desirable. People don't buy leather because they want an animal to be killed. They buy leather because of its look, feel, quality, and performance all of which can be replicated using non-animal and less environmentally damaging materials. This report lays out the attributes brands look for in leather, how to test for them, and what metrics material companies need to meet in order to satisfy brand requirements. The more we understand why people purchase leather, the better we can produce materials which meet their needs but are animal-free and more sustainable.

We will be adding new reports every month. Please check back here or sign up for our newsletter for updates.
