The ambition to replace the synthetic fibers polyester and polyamide in textiles has led to Renewcell and HeiQ forming a strategic partnership to manufacture circular HeiQ AeoniQ cellulose filament yarn from Circulose pulp supplied by Renewcell. This partnership enables the incorporation of recycled raw materials in a modern and environmentally friendly yarn production process that facilitates 100% circularity in the textile industry.
Capitalizing on their shared vision of a circular and bio-based textile industry, HeiQ Materials AG, Zurich/Switzerland and Renewcell, Stockholm/Sweden, have joined forces to commercialize 100% circular and biobased high-tenacity filament yarns as a viable replacement for fossil-based fibers like polyamide and polyester at scale. Promising results in initial tests using Circulose as a feedstock for production of HeiQ AeoniQ yarn create an opportunity for collaboration between the partners in their effort to lead the current textile industry transformation, positioning both companies and Europe as a pioneer region incorporating recycled raw materials in the most modern and environmentally friendly yarn production processes that allow true circularity in the textile industry.
Circulose is a branded dissolving pulp product that Renewcell makes from 100% textile waste, such as worn-out jeans and production scraps. Dissolving pulp cellulose is what the textile industry uses to make viscose, lyocell, modal, acetate other types of regenerated fibers. The only difference with Circulose is that it is made from textile waste instead of wood. Cellulose is the most abundant organic polymer in the world. It's what makes up the cell walls of most plants and trees. The purest cellulose found in nature is cotton.
HeiQ AeoniQ yarns are made out of cellulosic biopolymers that during growth bind carbon from the atmosphere while generating oxygen. This high-performance yarn is positioned to potentially substitute synthetic filament yarns which constitute over 60% of global annual textile output. Further, when compared to conventional cellulosic products, HeiQ AeoniQ yarns do not draw on arable land, pesticides or fertilizer in their production. HeiQ AeoniQ yarns are designed for cradle-to-cradle circularity and can be recycled repeatedly while maintaining consistent fiber quality. The manufacturing process is expected to consume 99% less water than cotton yarns and HeiQ AeoniQ is designed to offer comparable performance properties to polyester, nylon and conventional regenerated cellulose yarns.
»This latest strategic partnership with Renewcell is further proof of how circularity motivated suppliers to the textile industry can collaborate and be the movers and shakers that drive the transformation of the industry to becoming more environmentally friendly. With Circulose as one source of feedstock for our HeiQ AeoniQ we will be rescuing tons of textiles from ending up in landfills and preserving our trees and forests. We eagerly anticipate uniting our ingredient branding expertise to jointly convince brands of the huge advantages of replacing all synthetic, fossil-fuel based textiles and how embracing circularity is both in their interests as well as those of their customers and the planet. «
