In 2019, Adidas expects to make 11 million pairs of shoes with recycled ocean plastic. That's more than double what it made in 2018. Adidas says the partnership has prevented 2,810 tons of plastic from reaching the oceans. But how are these shoes made? It all starts at the beach. Parley and its partners collect trash from coastal areas like the Maldives. The waste is then sorted, and the recovered plastic is sent to an Adidas processing plant. Adidas uses plastic bottles that contain polyethylene terephthalate, or PET. And if it's something Adidas can't use, like caps and rings? Those get sent to normal recycling facilities. The processing plant crushes, washes, and dehydrates the waste, leaving nothing but small plastic flakes. The flakes are heated, dried, and cooled, then cut into small resin pellets. Normally, polyester is made from petroleum. But Adidas melts these pellets to create a filament, which is spun into what they call Ocean Plastic, a form of polyester yarn.
