The fashion designer intends to use Parley for the Oceans recycled plastic yarn instead of woven or recycled polyester in her line of shoes, accessories and outerwear.
She has previously designed a sneaker for adidas in partnership with the non-profit organisation which aims to raise awareness of the beauty and fragility of the oceans and to inspire people to find a solution to eliminate plastics from the sea.
McCartney said: “To take something that is destructive and turn it into something that’s sexy and cool, how can that not be luxury?
“When I was younger, leather equaled luxury and people could not get their head around the fact that I was not using leather. Leather is cheaper than some of the non-leather alternatives, it’s less interesting or fashionable.
“Is a recycled plastic ever going to be something people think is a luxury? If they don’t notice it and if they feel that living on this planet longer is a luxury, then yes, to me that’s my idea of luxury.”
Cyrill Gutsch, Founder of Parley for the Oceans, said: “We felt by creating a premium material out of this trash, we can raise awareness for the problem in general.”
Stella McCartney expects to roll out pieces made with Parley’s material next month. One of the first pieces is a backpack, made from recycled marine plastic. 100 per cent of the proceeds will go towards Sea Shepherd, an international nonprofit ocean conservation organisation.
The label has already teamed up with the Natural Resources Defense Council and the Wildlife Friendly Enterprise Network and prefers to rely on materials such as viscose sourced from non-endangered or ancient forests and cashmere derived from post-factory waste.
