OnceMore® and TreeToTextile brought together leading brands, retailers and industry experts in Sweden for a field trip demonstrating how next‑generation man‑made cellulosic fibres (MMCFs) can move from innovation to scale – spanning the full value chain from forest and recycled textiles to pulp, fibre and end‑use.
OnceMore® from Södra and TreeToTextile AB have completed a one-and-a-half-day field trip in Sweden, bringing together brands, retailers, and industry experts for an end-to-end view of how next-generation man-made cellulosic fibers (MMCFs) can be scaled; from responsible forestry and recycled textile feedstock to dissolving pulp, fiber innovation, and end-use applications.
The field trip was arranged in connection with the Challenge The Fabric conference in Paris, and in collaboration with the global non-profit organization Textile Exchange. Participants visited Swedish forests owned by one of Södra’s more than 50,000 members, toured OnceMore® production at Södra’s mill in Mörrum, and visited TreeToTextile’s demonstration plant in Nymölla. It was a first, showcasing how innovation in the earliest steps of the value chain can drive sustainability while also enhancing the properties of the final garments.
By opening their doors together, OnceMore® from Södra and TreeToTextile enabled participants to connect strategy with operational realities, including forest stewardship and traceability, the integration of recycled textile waste into dissolving pulp, and the technical pathway toward next-generation cellulose fibers designed to complement existing material portfolios.
The program also included a sample session featuring fashion items already on the market based on OnceMore® pulp, as well as apparel and home textile samples crafted from TreeToTextile’s Nyense™ fiber, enabling dialogue on performance requirements, sourcing considerations, and what is needed to move from pilots to broader adoption.
“Scaling innovation is about building confidence, in performance, in supply chain readiness, and in the people and partners behind the technology,” says Dr. Roxana Barbieru, CEO of TreeToTextile. “It was highly valuable to host open discussions with brands and experts on what is needed next, and to share progress from our demonstration plant as we continue the journey toward industrialization.”
“The textile industry needs solutions that work in practice, and that requires transparency and collaboration across the value chain,” says Tina Lemke, Marketing & Brand Experience Manager, OnceMore® from Södra. “This field trip created a shared baseline, from sustainable forestry and recycled textile feedstock to industrial production, and it gave participants the opportunity to ask detailed questions and see the processes up close.”
Adam Gardiner, Recycling Lead at Textile Exchange said:
“The opportunity for brands, retailers and industry partners to visit production systems is key to understanding how materials are made and how production systems can be improved. This trip provided valuable insights into textile-to-textile recycling as well as responsible forestry management practices.”
What participants experienced during the field trip
- Sustainable forestry practices in FSC® & PEFC™-controlled Swedish forests
- OnceMore® dissolving pulp production, integrating recycled textile waste with wood from responsibly managed forests
- TreeToTextile’s demonstration plant in Nymölla and the development of its next-generation cellulose fiber
- Hands-on sample session with materials and products made from OnceMore® pulp and TreeToTextile’s Nyense™ fiber
Key outcomes
- Shared understanding of traceability and stewardship considerations from forest to fibe
- Deeper technical dialogue on feedstock, process requirements, and performance expectations for MMCFs
- Identification of next collaboration topics, including data needs, sampling, and pathways to scale
- Increased alignment on the role of recycled textile content and next-generation fibers in diversified material strategies
Participant perspectives
”The field trip was a great experience and truly gave us the opportunity to witness something exciting. In a few years’ time, I will be able to say that I was there from the beginning, when you first opened your the Demo plant to an external audience and demonstrated what can be achieved with this new fiber technology. For ZDHC, we must acknowledge the challenges involved in developing new technology and ensure that our guidelines and tools are designed to match the new conditions that such innovation brings.”
Maria Arroyo, Sector Partnership Lead, ZDHC
“The development of next-generation cellulose fibers is really exciting for the MMCF industry. Not only is it a matter of sustainability, it is also imperative that we remain competitive in Europe and become less dependent on imported resources.”
Frédéric Van Houte, Director General, CIRFS
“This field trip highlighted the importance of looking at environmental impact as well as material performance when evaluating new fiber solutions. In addition to promising environmental performance, TreeToTextile’s fiber shows characteristics such as low pilling and strong color fastness, which are important to support garment durability.”
Anneke Keuning, Nature & Climate Impact Manager, BESTSELLER
About the field trip
The field trip took place May 28–29, 2026, in Mörrum and Nymölla, Sweden, with start/end in Copenhagen, Denmark. The program was designed for brands, retailers, industry experts, and textile value chain partners seeking deeper insight into scalable MMCF pathways.
