Treekind® is an innovative, low-resource material that is often used as an alternative to leather. Treekind® is developed by UK-based Materials Science company, Biophilica.

Treekind® is made by combining fallen tree leaves (lignocellulosic feedstock) with a natural binder. It is fully biodegradable and can be home composted.

Treekind has the following certifications:

• 100% biobased by the USDA's BioPreferred Program.
• 100% vegan by PETA (Navigate to "Vegan Leather" then "+ See the full list of suppliers")

Treekind® has been ranked the #2 leather alternative in the world by Ecocult.

As Treekind® does not use wood, the material does not require FSC (Forest Stewardship Council) certification.

Water droplets will not start the biodegradation of Treekind®. Rather, the material begins to breakdown only when introduced to the compost.

Treekind® has passed the test for home composting (ISO 14855), with 97% of the material biodegrading in 281 days.
