Why Mylo™ is the future of fashion
In 2017, Stella McCartney partnered with the visionary scientists and innovators at Bolt Threads. Bolt Threads grow mycelium in a vertical farming facility with just air, water and mulch to recreate a process that naturally occurs beneath the forest floor, using ingredients found in nature.
Mylo™ feels more substantial and elevated in comparison to many other animal leather alternatives, thanks to the way it is created. The mycelium is harvested as a ‘foamy layer’ – uniquely mimicking the microstructure of collagen – giving the final material a supple warmth and sponginess that is not possible in 100% synthetic options.
Additionally, Mylo™ is treated by highly skilled artisans who add a special finish that protects and enhances the luxurious feel of the material. This is created according to Green Chemistry principles – without the use of harmful chemicals like dmfA and chromium, which are commonly used in animal leather production.
Why we believe in replacing animal leather
As well as being needlessly cruel, the environmental and social impact of producing animal leather is incredibly high. Animal agriculture accounts for around 19% of the world’s total greenhouse gas emissions and is driving the destruction of our rainforests.(1)
According to the WWF, the farming of cattle for beef and leather products is responsible for 80% of the Amazon’s deforestation. Around 1.4 billion hides and skins of animals were used in global leather production in 2020 alone. That is approximately one animal for every five people on the planet. (2)
Leather tanning is commonly outsourced to developing countries, where people must work in poor conditions with little safety or protections in place and are exposed to harmful and carcinogenic tanning chemicals. In Bangladesh, 90% of tannery workers die before the age of 50. (3)
