Teijin Frontier develops new chemical recycling technology for polyester fibers

Teijin Frontier Co., Ltd., the Teijin Group's fibers and products converting company, announced today that it has developed a recycling technology using a new depolymerization catalyst to recycle colored polyester fibers without losing the quality of polyester fibers made from petroleum-derived raw materials. The new technology also lowers environmental load compared to conventional recycling.

The technology produces recycled materials equivalent to petroleum-derived polyester raw materials. Using a new depolymerization catalyst for the conventional bis (2-hydroxyethyl) terephthalate (BHET) method, spent polyester is chemically decomposed and purified back into BHET intermediate raw material before being repolymerized into polyester. The production process is simpler than using dimethyl terephthalate (DMT) and ethylene glycol in a transesterification reaction, so recycling is achieved with less energy consumption. Also, the new technology reuses resources such as wastewater, waste liquid and depolymerization catalysts.

Teijin Frontier will launch a pilot facility at its Matsuyama Plant this month and proceed with verification tests. It also will continue developing recycling technologies to improve the quality of recycled polyester raw materials and reduce environmental load. Aiming to realize a sustainable value chain for a circular economy, Teijin Frontier is working to establish a mechanism for sustainable fiber-to-fiber recycling of polyester in cooperation with partner companies and consortiums both in Japan and global.

Compared to material recycling, which melts and molds used products including polyethylene terephthalate (PET) bottles, DMT-based chemical recycling results in less deterioration of quality due to recycling, but its energy consumption is high. The BHET method is often used when recycling from colorless and transparent PET bottles as new PET bottles, and also its energy consumption is lower compared to the DMT method, but there were difficulties in producing high-quality recycled polyester raw material because foreign substances, such as dyes used for colored polyester fibers, could not be completely removed, resulting in discolored recycled raw material.

Teijin Frontier, guided by its THINK ECO® environmental initiative, is striving to improve its environmental value, including through eco-friendly plant management and the development of greener materials and products for applications ranging from clothing to industrial materials.

Teijin announces availability of DPP-compliant products aligned with Europe’s ESPR Environmental Regulation

Teijin Limited announced today that it has started rolling out initiatives to enable aramid fibers and carbon fibers to be accompanied by Digital Product Passport (DPP) technology, which enhances supply chain transparency by verifying the origins of materials and supporting sustainability claims. The company is using the supply chain traceability system from Netherlands-based Circularise B.V., in which Teijin has invested since November 2024, to develop DPPs for each product.

The milestone establishes the industrial recycler among a select group of manufacturing infrastructure providers verified as meeting B Lab Standards for social and environmental performance, transparency, and accountability.

Recover™ and Ünteks Group partner to scale recycled cotton in knitwear

Recover(TM), a global producer of low‐impact, high‐quality recycled cotton fiber, announces a new partnership with Ünteks Group, a vertically integrated textile manufacturer based in Turkey. The collaboration focuses on the development of circular knit fabrics and garments, combining Recover’s recycled cotton fiber with Ünteks Group’s integrated capabilities across knitting, dyeing, printing, and garment production.

ALADIN paves the way for circular and demand-driven textile production in Europe

Textile production can be organized sustainably by utilizing short supply chains and preventing overproduction. This can already be achieved today by intelligently connecting and efficiently utilizing existing infrastructure. At the same time, production becomes circular when innovative technologies and materials are used that enable high-quality recycling. The ALADIN research project, launched in May 2026 and co-funded with five million euros under the EU Horizon Europe program, is creating the conditions for this.

Ence and ShareTex begin initial testing of the ATENEA innovation project to promote textile recycling in Spain

Ence and ShareTex are making progress on the Atenea R&D project, which aims to develop a complete value chain for textile recycling in Spain. Specifically, the goal of the ATENEA project—which is funded by the Center for Technological Development and Innovation (CDTI)—is to connect all the necessary stages for the recovery of textile waste, from collection and management, through recycling and transformation into new raw materials, to their incorporation into new textile products.

Rieter sees Barmag integration on track as orders and sales rise

The first half of 2026 was shaped by the successful completion of the largest acquisition in Rieter’s history. The Man-Made Fiber Division enables entry into the growth segment of man-made fibers and sustainably strengthens Rieter’s market position in the Asia region. The expanded Group is now the world’s leading system supplier for the processing of natural and man-made fibers. In the first half of the year, initial cost savings in material costs and operating expenses have already been realized. The targeted synergies are expected to amount to at least CHF 20 million by the end of the 2028 financial year. Due to the completion of the acquisition on February 2, 2026, the first half of the year for the Man-Made Fiber Division only amounts to five months.
