The bark boiler will reduce reliance on fossil fuels, while the new digester is expected to improve energy and water usage across production and has further enhanced the strength of the company’s paper products.
The Dynäs mill holds official recognition from the Swedish edition of Guinness World Records for producing the world’s strongest paper.
The fibre line and digester were brought into operation during the site’s annual maintenance shutdown in May 2025.
