The Green Machine, created by Hong Kong Research institute of Textiles and Apparel (HKRITA), is the world’s first technology that can separate blended textiles at scale, without any quality loss.
Green Machine is a polyester and cellulose recycling system by hydrothermal treatment and dissolution treatment on cotton and polyester blends. Through decomposing cotton into cellulose powders, it enables the separation of the polyester fibres from the blends. The quality of the polyester fibres is maintained, permitting fiber-to-fiber recycling. Recycled cotton cellulosic powder will be used in re-spinning and agriculture.
And it was selected as one of the winners of the 2022 R&D 100 Awards in the category of Process/Prototyping.
