Spinnova has begun a new round of testing at its Woodspin demonstration plant in Jyväskylä, Finland, as it works toward bringing the facility back into regular operation. The company said the Spinnova Woodspin trial runs are designed to confirm efficiency improvements and quality enhancements before it commits to a full production restart, which it is aiming to achieve in 2026.
According to Spinnova, the latest trials will focus on raising output efficiency by implementing technological solutions that have already been proven in smaller-scale pilot work. The company added that results from the trial phase will directly shape the schedule for restarting larger-scale production at Woodspin, with the broader objective of returning the site to steady operations next year.
Woodspin, which opened in May 2023, is a demonstration-scale facility with an annual nameplate capacity of 1,000 tonnes of fibre. The plant produces Spinnova fibre using the company’s patented mechanical process, converting wood pulp—or certain waste streams—into textile fibre without dissolving the raw material and without using harmful chemicals. Spinnova positions the fibre as a material that can be blended with other fibres to create yarns and fabrics suitable for cotton-like applications, including apparel and accessories.
Spinnova CEO Janne Poranen said the company plans to ramp activity gradually and treat the trial phase as a key proof point for improved performance. “Our aim is to proceed with the ramp-up of the demo facility step by step, and the upcoming trial runs are an important step towards starting actual production. With the trial runs now starting, we aim to validate the technological solutions tested at a smaller pilot scale to improve production efficiency and fibre quality. This is a key phase in delivering Spinnova fibre to customers and scaling our technology to an industrial level, which is the direction we are heading.”
The Woodspin restart effort follows a change in ownership structure. In October 2025, Spinnova took full ownership of both the Woodspin and Suzano Finland demonstration factories, after binding agreements were executed in August 2025. The sites have since been placed under the Spinnova Refining unit, which houses infrastructure used both to produce Spinnova fibre and to prepare microfibrillated cellulose (MFC), a key raw material in the process.
With Spinnova Woodspin trial runs now underway, investors and customers will be watching whether pilot-validated upgrades translate into stable efficiency and quality gains at demonstration scale—an important step for any later move toward broader industrial deployment.
