Resortecs x Decathlon: Industrialising Recyclable Swimwear

Resortecs has joined forces with Decathlon, the global leader in sports equipment and apparel, to develop a fully recyclable swimwear collection without compromising performance, functionality, or aesthetics. This collaboration blends state-of-the-art technology with high-performance design.

Acerina Trejo Machin, the Chief Technology Officer at Resortecs, explains, “We all know that a high percentage of elastane prohibits the recycling of fabrics, but eliminating elastane lowers the functionality and performance of a garment. To balance performance and recyclability, Decathlon developed Negombo, a fabric ensuring elasticity without the use of elastane.”

However, creating a swimwear garment with a recyclable fabric alone isn’t enough to meet the required performance and comfort, for which elastic bands are needed. Those elastic bands are not processable by recyclers and block the recycling of the swimwear. This is where Resortecs comes into play. Resortecs’ Smart Stitch™, combined with Smart Disassembly™, enables the efficient separation of the elastic bands from the main fabric at the end of the garment’s life cycle.

Acerina elaborates, “Resortecs’ active disassembly process ensures the maximum recyclability rate of the swimwear garment. Our technology allows for fully automatic disassembly, without any manual intervention, at a scale of up to 10 tons a day. This results in an impressive 63% increase in material recovery and is 10 times faster than conventional methods.”

The synergy between Resortecs and Decathlon allows for the creation of swimwear that is not only high-performing but also fully recyclable, without making any compromises in design, durability, or comfort. 

Closing the loop has never been easier. By incorporating Resortecs’ disassembly solution, product designers can ensure circularity while focusing on their ultimate goal: creating garments that best fit their customer needs.

HNST Studio, the Antwerp-based label dedicated to creating jeans that embody transparency and circularity, partners with Belgian eco-design innovator Resortecs to launch new products made to be unmade—easy to disassemble for repair and recycling at the end of life.

The partnership debuts with the newly introduced Geri (for women) and Simon (for men) pants: crafted with up to 70% recycled cotton, these are HNST’s first jeans to feature an elastic waistband and drawstrings for unparalleled day-to-day comfort and flexibility. 

Completely eco-designed for recycling, the jeans’ waistbands are stitched using Resortecs’ Smart Stitch™, an award-winning thread engineered to disappear under heat. This thread change at the design phase ensures that the jeans can be disassembled without manual intervention at the end of their lifecycle—allowing for their recyclable fabric to be automatically sorted out of the non-recyclable materials added to the waistband for more comfort. 

“Our other jeans didn’t have elastic waistbands because they would be critical blockers for recycling. Collaborating with Resortecs allowed us to explore new possibilities to give our customers more comfort without compromising our non-negotiable commitment to circularity” stated Eva Engelen, Sustainability and Product Manager at HNST.

“We are two Belgian innovators trying to rewrite the future of fashion in a circular way,” said Cédric Vanhoeck, CEO at Resortecs. “This partnership with HNST showcases how our technology can unlock new possibilities for fashion players that want to design for recycling while keeping the creativity, functionality, and quality of their products”, he added.

The Simon and Geri pants are just the first drop of the HNST x Resortecs partnership. Both companies are committed to further integrating Resortecs’ design-for-disassembly solutions into other HNST designs, solidifying their shared vision of establishing circularity as the standard in the fashion industry. Consumers everywhere can now shop the collection at letsbehonest.eu and at select independent retailers in Europe, North America, and Japan.
