Stella McCartney Releases World’s First Biodegradable Stretch Denim

Stella McCartney is continuing her lifelong commitment to sustainability by creating a new, innovative pair of jeans. The biodegradable stretch denim has been created in partnership with the Italian manufacturer Candiani, who have been world leaders in responsible denim production for 80 years. The material was made using plant-based yarns and organic cotton was wrapped around a natural rubber core, which resulted in a fabric free from plastics and micro-plastics. The material, Coreva Stretch Technology, is innovative but doesn’t compromise on elasticity and recovery properties.

The average pair of 100% cotton jeans requires 7,600 litres of water, from the water required to grow the plants through to the dying process which releases toxic chemicals into the water. These dyes are harmful for the environment and also pose a threat to workers' health and safety. However, Stella McCartney states that Coreva is produced in a safe, toxic-free environment. Two processes reduce the consumption of water, energy and release of chemicals; Kitotex Vegetal, a patented biodegradable ingredient that replaces sizing agents, and Indigo Juice which keeps the indigo superficially on the yarn.

The collection includes ten pieces in two colours and five styles. There are two flared pairs, one cropped, the other long, and a beautiful straight leg cut with a mid-waist. So, it seems that style no longer has to compromise to nature.

The biodegradable jeans will be available in-store and online globally from May 2020.
