BP Petrochemicals is testing a new technology to enable circularity for unrecyclable PET plastic waste that can also be used to recycle plastic into polyester for clothing, according to the company. The BP Infinia technology involves converting complex PET plastic waste back to monomer feedstocks through chemical depolymerization. The technology also aims to purify these monomers into recycled purified terephthalic acid and recycled monoethylene glycol, which would then be interchangeable with those produced from traditional hydrocarbon feedstocks. The recycled feedstocks could then be used to make high-performance polyester for packaging, industrial fiber products and applications, and indeed clothing.
