Adidas will launch new fabrics made from recycled polyester and marine plastic waste and expand the product lines that use them after the success of shoes made with the Parley for the Oceans initiative, the sportswear firm said Tuesday.

Adidas first teamed up with Parley in 2015 and gradually ramped up production of shoes using plastic collected on beaches and coastal regions to make more than 11 million pairs in 2019, still only a fraction of a group total of more than 400 million.

The Ellen MacArthur Foundation, a charity that promotes shifting the economy to a circular model that eliminates waste, says less than 1 percent of material used for clothing is recycled, a loss of more than $100 billion (¥10.9 trillion) worth of materials each year.
