Mondi overhauls Swedish kraft paper mill for improved energy and production efficiency

11 May 2023 --- Mondi is modernizing its Dynäs pulp and paper mill in Sweden to increase efficiency and further improve the overall environmental performance. 

The project includes installation of new and upgraded machinery to improve energy and production efficiency at Mondi Dynäs in Sweden. Investing in the future of the mill, Mondi is upgrading the mill to meet customer demand for paper-based packaging solutions. 

Roman Senecky, chief operating officer at Mondi Kraft Paper, says: “The modernization program at Dynäs represents a significant investment in the future of this well-established mill.” 

“By producing sustainable sack and specialty kraft paper, we continue to contribute to our MAP2030 goals and meet customer demand with innovative solutions such as Advantage StretchWrap, an alternative to plastic film pallet wrapping, and Advantage MF EcoComp, used for high-strength packaging like paper bags for wet organic household waste. The mill supplies paper across Europe and plays an important role in the local community.”

The Dynäs mill produces high-quality sack and specialty kraft papers used for various paper-based packaging solutions. Upgrades for reduced emissions
The Dynäs mill produces high-quality sack and specialty kraft papers, used for various paper-based packaging solutions for industrial and consumer industries. The mill is said to be an important part of Mondi’s Flexible Packaging business. 

The project includes installing and upgrading machinery and equipment, such as a new cooking plant and bark boiler, which will improve the mill’s energy efficiency, says Mondi. Upgrades will further reduce air and water emissions, resulting in better wood utilization at the mill. 

The Swedish Land and Environmental Court approved Mondi’s modernization works application in March 2023. Construction is expected to be completed by the end of 2026.

Paper in the news
Last week, DS Smith kickstarted a new “state-of-the-art” combined heat and power (CHP) plant at the UK’s largest mill for recycled paper. The CHP plant – financed, built and operated by energy provider E.On – has been designed to reduce CO2 emissions by 36,000 metric tons per year. 

With the new CHP plant, E.On equipped DS Smith with an electrical capacity of 73 megawatts, generating steam and power to boost the Kemsley Paper Mill’s manufacturing capacity to over 830,000 metric tons of recycled paper yearly.

DS Smith also invested €145 million (US$159 million) into its paper mill in Viana, Portugal. The investment package included rebuilding the existing paper machine and a new recovery boiler, one of the most modern in Europe, says DS Smith.

The boiler is said to improve environmental performance by enhancing steam efficiency at the mill by 25%, with steam from the boiler being recycled back into the mill. The new boiler, provided by Valmet, is expected to start up in early 2025.

Meanwhile, UPM Communication Papers invested €100 million (US$109 million) in its Nordland Papier mill in Dörpen, Germany, to reduce CO2 emissions by 300,000 metric tons annually. The investment increased energy in the facility and fed surplus power back into the electricity grid, contributing to Germany’s energy security.
