Through our global Innovation Platform, Fashion for Good supports critical innovations on their journey to scale, providing hands-on project management, access to funding and expertise, and collaborations with brands and manufacturers to accelerate implementation in the fashion supply chain. In this series, we are proud to introduce some of the groundbreaking innovators who are driving the change to make fashion a force for good.

In its current state, the mainstream production of conventional animal leather is linked to serious sustainability issues at each step of the supply chain, often requiring significant energy and harmful chemicals in its production. But, mainstream ‘leather’ alternatives are not always a good sustainable alternative, as they’re commonly made from different types of plastic polymers, making them neither sustainable nor biodegradable.

Biophilica has developed a technology that converts green waste into a new ‘leather’ alternative called Treekind®. The innovator collects leaves, agricultural waste, and other green waste, also known as lignocellulosic materials, from London parks, dries and turns them into a powder, that then is mixed with a natural binder and dried into sheets. The resulting material is then coated in a bio-based layer to make it water resistant/repellent.  

Treekind® can be recycled or home composted as verified in the ISO 14855-1 test. It uses less than 0.1% of the water equivalent to leather processing and has a very low carbon footprint. It is non-toxic, PETA vegan certified, and contains zero plastic, while delivering on performance.

Treekind® material is compostable, which has now been verified in the ISO 14855-1 home composting test performed by Eurofins Ecotoxicology in France, and it’s currently in the process of becoming USDA certified as 100% biobased. 1kg of Treekind® material uses less than 0.1% of the water used in conventional leather processing, has zero toxic chemicals in its formulation, and because of its plant content, boasts a significantly reduced carbon footprint compared to leather.

In the next few months, they will be working on scaling their Treekind® ‘leather’ alternative to a roll-to-roll manufacturing process, which will enable production at scale. They are planning the commercial release of their 100% biobased adhesive and they are working on exciting new brand partnerships.
