The Hong Kong Research Institute of Textiles and Apparel (HKRITA) has launched a tripartite initiative, the Green Machine Circular Textile Ecosystem in collaboration with Jeanologia and Looptworks. This strategic alliance transitions hydrothermal recycling from localized laboratory trials to industrial-scale application. At the core of this infrastructure is the Green Machine 4.0, a proprietary system capable of separating cotton-polyester blends and recovering polyester at a purity level of 98 per cent or higher. By eliminating the reliance on aggressive chemical processes, the technology addresses a persistent bottleneck in apparel sustainability: the inability to effectively recycle blended materials.
Engineering industrial integration
The partnership leverages the unique strengths of each participant to ensure operational viability. Jeanologia, serving as the official machinery partner, is contributing industrial-grade equipment engineered to stringent European CE high-pressure standards, ensuring the ecosystem can be deployed across global production hubs. Meanwhile, Looptworks will utilize the output to manufacture Global Recycled Standard (GRS)-certified fibers, effectively reintroducing them into the supply chain. Jake Koh, Chief Executive Officer, HKRITA, noted that the circular economy has moved beyond a theoretical goal, emphasizing that the Green Machine is now fully ‘adoption-ready’ to meet the urgent requirements of brands striving to reduce virgin resource dependency. As the global recycled textile market continues its projected expansion, this ecosystem offers a definitive pathway for manufacturers to convert waste into high-value raw material streams, despite the operational challenges of managing mixed-material input.
Focusing on circular economy and functional fiber development
A leading research center dedicated to advancing textile technology, The Hong Kong Research Institute of Textiles and Apparel (HKRITA) focuses on circular economy solutions, sustainable manufacturing, and functional fiber development. The institute collaborates extensively with global brands and manufacturers to commercialize breakthrough technologies, significantly improving efficiency and reducing the environmental footprint of the textile and apparel sector.
