Since its implementation in 1990, Nike's Reuse-A-Shoe program has recycled 28 million pairs of used shoes. They collect the worn out sneakers (those you can't donate), break them down into three parts: rubber, fabric, and foam, then transform them into raw materials for soccer fields, running tracks, tennis courts, basketball courts, carpet padding and climbing wall decks. Since its implementation, Nike started working on the design of the new footwear in order to make it easier to recycle them; Their ultimate goal is to close the recycling loop to make new Nike products out of old ones.
This is one of those success stories where the community wins, the environment wins and the company improves the way people see their brand.
