Technological watch

Teijin Limited, JGC Holdings Corporation and ITOCHU Corporation announced that they formally agreed to establish a joint venture company, RePEaT Co., Ltd., to license technology for the chemical recycling of polyester products.
Recycled PET with Same Quality as Petroleum-derived PET
The new joint venture will use a chemical-recycling technology called dimethyl terephthalate (DMT), which decomposes and converts polyester (PET) and then repolymerizes it. Notably, the DMT method removes dyes and impurities, making it possible to manufacture recycled PET with the same quality as petroleum-derived PET.
Teijin has extensive experience in using DMT technology for the commercial production of polyester products including colored textile waste and colored PET waste. In response to urgent needs to counter global warming, the fiber and textile industry is working on measures, including the establishment of ecosystems for resource recycling, to address issues such as CO2 emissions from manufacturing processes and the mass disposal of used clothing.
Currently, disposed textile products are used as a heat source (thermal recovery) or as raw materials for the production of other products (material recycling). Chemical recycling, however, is a revolutionary method that uses chemical decomposition for textile-to-textile recycling that turns used textile products into new textile raw materials. After concluding a preliminary agreement in April 2021, the three companies explored commercial opportunities to globally license the technology, utilizing Teijin’s DMT expertise and know-how, JGC’s general engineering experience and know-how in plant construction, and ITOCHU’s global network in the textile industry.

Consulting Services to Promote Recycling
In view of the strong global demand envisioned for their licensed technology, the partners have now decided to proceed with establishing a commercial joint venture. RePEaT will license recycling technology that was first developed by Teijin and then jointly streamlined and packaged by JGC and Teijin. Customers in Japan and other countries are expected to use the technology to launch chemical-recycling businesses for the production of polyester products.
In addition to technology licensing, RePEaT will provide consulting services to help customers establish ecosystems that collect used polyester fiber products for reuse as raw materials, thereby contributing to a more sustainable world through recycling.
