Nike Grind
From Wikipedia, the free encyclopedia
Nike Grind is part of Nike's Reuse-A-Shoe program that was started in 1993. The purpose of the program is to eliminate waste and close the loop on Nike's product lifecycle by collecting post-consumer, non-metal-containing athletic shoes of any brand, including Nike shoes that are returned due to a material or workmanship defects.
Once collected, the sneakers are ground up and separated into three distinct types of material: rubber from the outsole, foam from the midsole and fabric from the shoe's upper. Nike and its partners (FieldTurf, Connor Sports Flooring, Rebound Ace and Atlas Track) take the granulated rubber and create soccer, football and baseball fields as well as weight room flooring. They use the granulated foam for synthetic basketball courts, tennis courts and playground surfacing tiles. The granulated fabric from the shoe uppers becomes the padding under hardwood basketball floors.
