Södra was founded in 1938 on the idea that we are stronger together. Södra is now the largest forest-owner association in Sweden, with over 50,000 family forest owners as members. Together, the members of Södra own a world-leading industry that processes forest raw material into renewable products such as paper and dissolving pulp, liquid bioproducts, energy, timber and building systems.

Founded in 1973 and after a few decades, the IMPETUS Group has become one of the world’s leading companies in the textile sector. What started with six people, four machines, and a family dream, has become the launchpad for an industrial and commercial presence with a global dimension.

Driven by nearly half a century of experience and a commitment to customers and the community, IMPETUS’ management remains solidly based on a family basis, backed by a new generation that shares the same values.

Currently, the IMPETUS Group is one of the most complete integrated vertical structures in Europe, supported by several departments, which, in addition to the production process, include R&D, Design, Quality, and Logistics. The improvement of this structure guarantees the flexibility and capacity to offer customers a service of the highest quality and adjusted to their needs.

Although it started by producing only underwear and loungewear, the experience and know-how acquired over the years, together with the significant investment in new technologies, allowed it to expand the portfolio to a wide range of technical products, such as workwear and sporty, with and without seams.

OnceMore® from Södra is the world’s first large-scale process for recycling blended fabrics. The process combines post-consumer textile waste with wood from responsibly managed forests to produce high-quality textile pulp.

– An industrialized solution that is commercially available, at scale.
– A drop-in quality solution performing as well as traditional viscose.

What was once waste becomes new products made from OnceMore® material and it’s the forest that makes it all possible.

Nanollose’s innovative fabrics begin life in a facility where microbes naturally ferment agricultural wastes and by-products into microbial cellulose, a cotton-like alternative to wood pulp. This is then transformed into the company’s Nullarbor™ fibre using the lyocell process by its partner, Birla Cellulose. The production of microbial cellulose requires very little land or energy and doesn’t contribute to deforestation. Moreover, the production cycle for microbial cellulose is just 12-18 days, compared to 12-18 years for the trees required for wood pulp. Nullarbor is also stronger than conventional lyocell made from wood pulp.

Accelerating Circularity is a nonprofit that catalyzes new circular supply chains and business models to turn used textiles into mainstream raw materials. ACP envisions a world where textiles are no longer wasted. Its approach is to research, map, model, and test circular, textile-to-textile systems from collection, sorting, preprocessing, and recycling through the conventional supply chain at standard commercial scale. The work demonstrates that textile-to-textile circular systems are feasible and worth engaging in for the entire supply chain. Because textiles are too good to waste.

Legislation, Policy, and Traceability

Over the last few years, we have seen an increase in legislation related to sustainability in textiles. For example, the EU Strategy for Sustainable and Circular Textiles will require the use of more sustainable and recycled materials as well as identification through the Digital Project Passport (DPP). Organizations such as the Textile Exchange are supporting the industry by developing standards to classify preferred materials. Also new startups are focusing on helping brands achieve visibility on their supply chains. How can fashion brands and suppliers alike navigate this new landscape? What role can stakeholders like innovators, NGO’s and industry organizations play? What is required to educate and disseminate knowledge on legislation, policy, and traceability? This panel will explore these important topics.
