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 the most 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 and Renewcell have joined forces to commercialize 100% circular and biobased high-tenacity filament yarns as a viable replacement for fossil-based fibers like nylon 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 (also called 'man-made cellulosic fibers').

The only difference with Circulose is that it's 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 (Aeon: striving for eternal circularity) 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 of 108 million metric tons.

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.
