From a DesignBoom online article:
the recycling technology is the result of a partnership between coca-cola, the dutch startup ioniqa technologies and indorama ventures, one of coca-cola’s suppliers of PET plastic. to process the material, ioniqa technologies used a depolymerization technology to break down the PET into its monomers that allow it to be re-produced as a new. it was then sent to an indorama ventures facility to be polymerized into new plastic.
coca-cola has introduced the world’s first bottle created using recycled plastic waste from the ocean. the company has launched an initial edition of 300 bottles made of 25% plastic from the marine waste collected by volunteers during 84 beach cleanups in spain and portugal.
