ANDRITZ Selected to Modernize MM Kwidzyn Pulp Mill with Low-Emission Cooking Technology

ANDRITZ LoSolids continuous cooking plant with a single-vessel digester

(IN BRIEF) ANDRITZ has secured an order to supply a LoSolids continuous cooking plant for MM Group’s pulp and paper mill in Kwidzyn, Poland, replacing the site’s existing batch digester system as part of a major sustainability-driven upgrade. The new installation will enable flexible softwood and hardwood pulp production while significantly reducing energy consumption and CO₂ emissions. Featuring advanced digestion, chip feeding, and heat recovery technologies, the project is scheduled to start up in the fourth quarter of 2026 and will play a key role in strengthening MM Kwidzyn’s efficiency, environmental performance, and long-term competitiveness.

(PRESS RELEASE) GRAZ, 15-Jan-2026 — /EuropaWire/ — ANDRITZ has been selected to deliver a next-generation cooking plant for MM Group’s integrated pulp and paper facility in Kwidzyn, Poland, as the mill advances a large-scale transformation focused on sustainability, lower emissions, and improved energy performance. The project represents a significant upgrade to one of the mill’s most critical production stages.

As part of the modernization, the existing batch digester system will be replaced with a LoSolids continuous cooking solution supplied by ANDRITZ. The new installation is designed to provide operational flexibility by allowing seamless transitions between softwood and hardwood pulp processing. This technological shift is expected to substantially reduce overall energy demand while lowering CO₂ emissions at the Kwidzyn site.

The scope of supply includes a single-vessel digester that enables uniform cooking conditions and greater control over the pulping process. To further enhance efficiency and product quality, ANDRITZ will install its Turbofeed chip feeding system together with a Diamondback chip bin, maximizing chip presteaming and ensuring consistent pulp characteristics. The delivery also features a vapor reboiler that improves heat recovery within the digester and reduces odorous gas emissions generated during operation.

Filip Drofiak, Chairman of the Board of MM Kwidzyn, emphasized that the investment strengthens both environmental performance and operational flexibility. He noted that the ability to process different wood types while cutting energy consumption supports the company’s sustainability ambitions and reinforces the mill’s competitive position, energy autonomy, and long-term resilience.

Commissioning of the new cooking plant is planned for the fourth quarter of 2026. Once in operation, the upgraded system will support MM Kwidzyn’s production of premium virgin fibre cartonboard for pharmaceutical and luxury packaging applications, as well as packaging kraft papers, uncoated fine papers, and pulp for a wide range of markets.
