Polyester product recycling

According to the announcement by Teijin Corporation of Japan, they have successfully developed a highly advanced recycling technology for polyester products. This new technology can make the recycled polyester product into its original composition material and then use it to make a new polyester product. The new technology can recover polyester raw materials DMT (dimethyl terephthalate) and EG (ethylene glycol) from the vast majority of polyester products. Even recycled polyester products contain some additives and materials that can be used during processing. The recycled, high-purity polyester formed after recycling can be equated with a petroleum feedstock product. Since 2002, Teijin Corporation in Japan will process 30,000 tons of waste polyester annually at the Tokuyama Plant in Yamaguchi Prefecture, equivalent to about 1 billion PET bottles. At the beginning stage, the PET bottles are mainly recycled, and the recycled materials formed after processing are used to make household products. This chemical recovery and reuse technology, together with the technology used by the God Company to use PET bottles to make fibers, is a tremendous contribution to the human society. The foundation of chemical recycling and recycling technology announced by Teijin Corporation in Japan was laid in 1962. After inventing the polyester fiber in 1958, it was chemically decomposed in order to utilize the polyester waste yarn produced in the production, but the new technology now greatly improves the original method because it can eliminate additives in the waste. And impurities during processing. Chemical recycling technology has expanded their existing business of making fiber from PET bottles. This new system can be used on most polyester products, economically reusing recycled raw materials into fibers, resins or films with the same quality as petroleum feedstocks. In addition, dimethyl terephthalate (DMT) made from the recycling bottle using the new technology method can also be made into terephthalic acid (TPA) by chemical reaction, and then the polyester bottle can be made. Teijin Corporation has applied for 57 patents in the recycling of polyester products.
