Swiss fluid engineering company Sulzer announced that its partnership with H&M Group and Worn Again Technologies is developing technology for closed-loop recycling of textiles. Because of the complexity of garment production, chemical recycling techniques to date have been applied to a minor share of end-of-use textiles and clothing. As the major technology partner for U.K.-based Worn Again Technologies, a company majority owned by Sulzer and H&M Group, Sulzer brings in its expertise with a new technology to recycle old textiles back into reusable textiles, enabling circularity. The teams will now engineer a demonstration plant and further scale up this novel closed-loop recycling process with a planned output of 1,000 tons per year. The new facility will convert used cotton and polyester garments into polyester pellets and cellulosic pulp that can then be re-spun into new fibers. Photo: Sulzer.
