The strategic heart of European textile recycling, the Ortviken plant in Sweden, is preparing to resume operations by the fourth quarter of 2026. Reborn under the brand name Circulose following a successful acquisition by investment firm Altor, the facility is poised to address the fashion industry’s raw material crisis. As the only commercial-scale plant in Europe capable of producing high-quality dissolving pulp from 100% textile waste, its restart marks a pivotal moment for the continent’s sustainability goals and the scaling of textile-to-textile recycling.
Located in the industrial zone of Ortviken, near Sundsvall, the plant’s transition to the Circulose brand follows a major rescue operation of its technological assets. The restart is not merely the saving of a unique innovation but a strategic move to stabilize the global textile supply chain, allowing international brands to integrate truly circular materials into their mass-market collections.
From Bankruptcy to Strategic Restart: The Evolution of Circulose
The path to restarting the plant was preceded by significant economic shifts. Renewcell, the company that originally established the facility, was forced to file for bankruptcy in February 2024, leaving the future of sustainable textile materials in Europe uncertain.
The turning point occurred in June 2024, when the Swedish investment firm Altor acquired Renewcell’s assets. The new owners have not only secured the technology and physical infrastructure but also streamlined the corporate strategy: both the company and its flagship product now operate under the unified name Circulose. According to Magnus Lundin, CEO of Circulose, the planned restart in the fourth quarter of 2026 (Q4) is essential for rebuilding market confidence and meeting the growing demand for circular fashion.
60,000-Ton Capacity and Technological Breakthrough
The technological foundation of the Ortviken plant is unique on a global scale. The facility specializes in processing discarded, high-cotton-content textile waste, purifying it at a molecular level, and transforming it into dissolving pulp. This pulp is then used by fiber producers to create viscose, lyocell, or other man-made cellulosic fibers that match the quality of virgin wood-based materials.
The plant’s planned capacities and metrics include:
-
Annual Capacity: At full utilization, the facility is designed to produce 60,000 metric tons of recycled pulp per year.
-
Raw Material Composition: The production process utilizes 100% textile waste, directly reducing the fashion industry’s reliance on forestry and virgin wood pulp.
-
Supplier Network: The company already coordinates the Circulose Supplier Network (CSN), which currently boasts 116 members (including yarn spinners and fabric mills) ready to receive and process the material.
The European Role and the Future of Circular Fashion
The scheduled launch of the Ortviken plant is of strategic importance to Europe. With the European Union’s tightening environmental regulations and the upcoming mandates for the separate collection of textile waste, industrial-scale processing capacities like Ortviken are indispensable. The facility serves as a cornerstone for the continent’s technological independence in the sector of recycled textile raw materials.
Circulose® has previously been integrated into collections by global fashion giants such as H&M, Inditex (owner of Zara), and Levi’s. The stabilization of the plant by late 2026 will enable these brands to scale their sustainability projects and meaningfully reduce the proportion of fibers sourced from fossil or virgin resources.
The return of Circulose is more than just the reopening of a factory; it is the practical, industrial-scale implementation of the transition from the textile industry’s linear model to a truly circular economy.
