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.

Currently, a large percentage of textiles end up in landfills or are incinerated, rather than being recycled or reused. Circ’s technology offers a solution to this problem by recycling polycotton — what the majority of our clothes are made of — into materials that can be re-entered into the fashion supply chain to make new clothing. The innovator’s hydrothermal process takes textile waste and turns them into materials that can be reused. 

By separating synthetic fibres (like polyester) from cellulosic content (like cotton, bamboo, lyocell, viscose, etc), they are able to recover the majority of the raw materials in textile waste, producing high quality fibre and reducing our reliance on virgin materials.
