Under the strategic partnership Circ will use Selenis’ polymerisation infrastructure and technical knowledge to convert recycled monomers derived from end-of-life textiles into premium-grade Circ Polyester.
This material is suitable for various apparel segments, including activewear, essentials, and high fashion. The partnership aims to provide a scalable, circular solution that can be easily integrated into current supply chains.
This collaboration is set to enhance the commercial production of Circ Polyester within Europe. It is also in line with the company’s efforts to offer circular alternatives for polyester and synthetic cellulosics like lyocell within the fashion industry’s supply chain.
Circ CEO Peter Majeranowski said: “Selenis has been a long-standing partner in our journey, and we’re proud to take this next step with them to bring Circ Polyester to market at industrial volumes. This is also a defining moment that affirms Circ’s dual-product strategy, offering both recycled lyocell and polyester — as we meet growing demand for circular materials across categories.”
Selenis, headquartered in Portugal, specialises in creating high-performance polyesters for diverse markets. Their alliance will propel the development of the next generation of recycled polyester and broaden the spectrum of circular solutions accessible to fibre producers, textile mills, and fashion brands.
Selenis CEO Duarte Matos Gil said: “This partnership reflects our commitment to reducing waste and scaling up advanced recycling solutions. “Circularity is no longer a concept; it must become an industrial reality. Whether it is bottle-to-bottle or textile-to-textile, the goal is the same: materials must complete a full life cycle and return as high-quality products, again and again. A bottle should become a new bottle, not downcycled. A garment should be reborn as another garment, not wasted. To achieve this on a scale, we need both innovation and regulation. Supportive, forward-looking legislation is essential to unlock investment and create a level playing field for truly circular systems.”
