Nike Grind is Nike's collection of recycled materials that is composed of pre-consumer manufacturing scraps, recycled post-consumer shoes from the Reuse-A-Shoe program, and unsellable footwear. The purpose of Nike Grind is to eliminate waste in line with the tenets of sustainable fashion practices and close the loop on Nike's product lifecycle. Materials recycled include rubber, foam, fiber, leather and textile blends, which are separated and ground into granules.[1]
Recycling process
Nike Grind materials are primarily composed of manufacturing scraps but also include a mixture of recycled and unsold shoes.[2][3] Many of the recycled shoes are collected through Nike's Reuse-A-Shoe program, which began in the early 1990s and takes in around 1.5 million pairs annually.[4]
