setup which can easily be adapted to accommodate changing sorting needs. A Heimdal RGB camera module is used for colour detection and AI classification of textile types. A Mimir NIR sensor module detects material composition and wet textiles, with pre-trained material compositions including cotton, viscose, polyester, wool, silk, and fibre mixtures such as cotton with elastane or cotton/polyester blends. The package also includes an Odin X-ray sensor module which uses AI to detect dense materials, such as buttons and zippers in metal and plastic, and also accurately measures the weight of each textile. NewRetex has developed the Hugin


manufacturing execution system, designed for traceability and streamlining sorting operations. Real-time monitoring of machine performance, material flow, and data storage, ensures maximum efficiency while tracing the textiles throughout the value chain, it says. The system registers incoming material, traces it through the sorting and recycling journey from waste input to recycled fibre output, and generates reports for the recycler’s downstream customers.


Another notable feature that Theilgaard


Lauridsen pointed out is the line’s conveyor technology for separating fractions. Instead of blowing garments into containers, commonly done in other systems, the NewRetex line is fitted with inclined conveyors that reverse when the textiles reach their designated exit to then be dropped down chutes into the relevant fraction containers. A sorting line can be fitted with any number of these Bifröst sorting modules.


Classifiers challenge Tomra Recycling is a long-standing supplier of sensor-based sorting technology, with decades of experience in the plastics and metals recycling markets. Recognising the need for high-tech solutions in the textile industry, Tomra has been dedicating resources to textiles development over the past decade. The Autosort is Tomra’s flexible


multifunctional sorting system, which combines NIR and VIS spectroscopy with other features such as AI. Louisa Hoyes, Segment Director Textiles – Business Development, told TextilesLoop at the


Textiles Recycling Expo that after circa 30 years of development, the Autosort technology is very well established. The company is busy working with a large number of textiles sorters and recyclers on two connected objectives: to ensure its technology is adapted to meet their needs and also to help drive market development. “I see my role as a consultant,” she said. Tomra is conducting a lot of work on the


development of classifiers for textiles for use in its sorting technology, which is no easy task given the variety of fibre types plus the complexity of blends and multi- material structures. Adding to the challenge is the fact that each recycler varies in the mix of waste it is targeting. This has led to Tomra operating an “open door” policy for textiles recyclers to test their feedstocks at its test centres, and this enables the company to gather the data that is vital in building its classifier database. Hoyes said that one challenge is that


there is no standardisation in textiles sorting and it is important for Tomra technology to be developed with adaptability. “What the technology needs to sort will change as downstream recycling


Leading the Way in Automated Textile Sorting NewRetex has developed the world’s first fully automated textile sorting facility with a traceability system. We specialize in automatic textile sorting and mechanical recycling, transforming post- consumer fiber into valuable new resources for the textile industry. Our mission is to be the market leader in textile sorting technology and to create high-value materials through innovative processes.


Advanced Technology and Sorting Facilities for Sale


We design and sell textile sorting lines that integrate artificial intelligence, data collection systems, and advanced sensor technology. Our systems empower companies to efficiently manage textile


waste, stay ahead of upcoming EU regulations, and actively contribute to a more circular economy.


Proven Results in Fiber Recycling


At NewRetex, we have accumulated extensive knowledge about post-consumer fibers and successfully developed yarns and products, proving that these fibers can be effectively recycled for the future of the textile industry.


Building a Scalable and Sustainable Supply Chain


We have established a strong and scalable supply chain that provides the industry with access to high-quality recycled fibers, yarns, and finished products—ready to be integrated directly into new collections.
