As it celebrates its 20th anniversary in 2026, the Hong Kong Research Institute of Textiles and Apparel (HKRITA) is solidifying its position as a global circular economy pioneer through strategic technology expansion into Mainland China. Their cutting-edge innovation, known as the ‘Green Machine,’ was recently honored as one of the ‘20 Shanghai Outstanding ESG Cases’ at the Corporate Sustainability Development Conference. This achievement marks a new chapter in the $2.5 trillion global apparel industry’s effort to solve one of recycling's toughest bottlenecks: separating polyester-cotton blends.
This hydrothermal separation technology can isolate polyester from cotton in blended textiles with a recovery rate of 97 percent. The ‘Green Machine’ stands out not only for its ability to process post-consumer waste but also for its remarkable energy efficiency. Industrial-scale trials indicate that the machine requires only 19 GJ of energy per ton of recycled PET—roughly 30 percent of the energy consumed in virgin fiber production. This efficiency gain is pivotal as the global textile industry faces mounting pressure to hit net-zero targets.
During a roundtable session in Shanghai, HKRITA CEO Jake Koh emphasized that a circular economy cannot rely on hardware alone. To achieve a net-zero supply chain, end-to-end carbon reduction is essential. "We are now advocating for digital monitoring and carbon footprint transparency to validate circularity for global brands," Koh stated. He added that this technological integration aligns perfectly with China’s National 15th Five-Year Plan, which prioritizes green upgrading and digital-twin manufacturing.
To bridge the gap from the lab to the market, HKRITA has also signed a Memorandum of Cooperation with Chengdu Qinggong Polytechnic University. This first-of-its-kind international research agreement targets talent development and startup incubation through the "Open Lab" residency program. The partnership aims to utilize Chengdu’s industrial resources to stabilize the supply of high-purity recycled cellulose powder while scaling HKRITA’s intellectual property within a major manufacturing hub.
These strategic moves demonstrate that scaling circularity in the textile sector relies as much on regional information exchange and technology sharing as it does on mechanical innovation. With a portfolio of over 150 patents, HKRITA is not just celebrating two decades of progress; it is building a bridge between Hong Kong’s innovation and the manufacturing power of Mainland China and ASEAN. Looking ahead, the ‘Green Machine’ is expected to become a global standard, transforming unmanageable waste into valuable resources that support a sustainable planet.
