Adidas Is Turning Plastic Ocean Waste Into Sneakers
How are These Shoes Made?
It all starts at the beach. Parley (Parley for the ocean) 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. Adidas uses Ocean Plastic to form the upper parts of shoes and clothing like jerseys. Each item in the Parley collection is made from at least 75% intercepted marine trash. And they still meet the same performance and comfort standards of Adidas' other shoes. Recycled polyester uses less water and fewer chemicals and helps prevent plastic pollution.
The yarn drawn from recycled plastic is divided into 3 grades. Most of the bottles on land are transparent and colorless, and their appearance is relatively clean, so they can be made into fabrics, which are class 1 materials. However, the color of the bottle that has accumulated in the sea for many years is blue, and there are many impurities on the card, which increases the difficulty of handling. In the past, if there were impurities in the raw materials, it would usually only be made of stuffed cotton and classified as a raw material of level 2.
It is not easy to reprocess the second-level raw materials into first-level materials that can be used in the upper.
