Mondi Dynas is undergoing a major transformation with a multi-year investment including a new fibre line, continuous digester, bark boiler, bark dryer and tall oil plant.
These upgrades will support the long-term competitiveness and operational stability of the mill, energy efficiency and environmental performance. The new bark boiler will significantly cut fossil fuel use, while the digester will improve energy and water management. The world’s strongest paper, officially recognised by the Swedish edition of the Guinness World Records, is now even stronger thanks to our new digester, which further helps to improve the strength properties of our paper. This means we are able to meet increasing customer demands for innovative kraft paper solutions.
This project at Dynas enables us to build a more agile business and drive Mondi’s future growth by increasing capacity, strengthening our competitive position in the market with reduced carbon emissions and improved resource efficiency, creating lasting value for our customers.
A major milestone for the fibre line
In May 2025, the project reached a key milestone with the successful launch of the new fibre line during the mill’s annual maintenance shutdown. This included the start-up of the new continuous digester, a critical step in improving pulp quality and reducing energy use.
Managing complexity while keeping operations running
Despite the mill’s limited space, the team has kept operations running with minimal disruption. Careful planning and close coordination have been essential, especially during the construction phases that brought up to 650 people on site, an increase of more than 50% compared to the usual number of employees on site. Safety has remained central throughout this large-scale project. Despite the additional people on site and complex construction activities, the team recorded only seven Recordable Cases. This strong outcome was supported by a simple but effective approach to on-site monitoring based on the “boots-on-the-ground” principle.
