ANDRITZ has received an order from Nordic Paper to deliver a new wood room with chip and bark handling for its Bäckhammar mill in Sweden. The new wood room contributes to meeting high pulp quality standards at the Bäckhammar mill. The plant will have the capacity to process over 1.4 million m3 sob of pine and spruce logs annually. The Bäckhammar mill manufactures unbleached kraft papers of different qualities primarily for packaging end-uses.
"The investment will further improve sustainability performance and strengthen the competitiveness of Nordic Paper Bäckhammar mill," said Christian Persson, Director of Operations at Nordic Paper. "The new wood room provides for both strategic flexibility in raw material sourcing and efficiency gains in production."
The scope of delivery includes a new debarking and chipping line with steam de-icing in the debarking drum, which ensures a high debarking degree with low wood losses and at the same time saves energy. This technology also significantly reduces water use and effluent water load.
Chipping in horizontally fed HHQ-Chippers ensures efficient use of the wood raw material and provides the highest chip quality on the market, ANDRITZ said.
In addition, efficient operation is supported by key digital packages from the ANDRITZ Autonomous Wood Processing product portfolio, which optimizes production and quality and ensures low wood losses. Chip quality is monitored with Metris ChipSCAN technology. The energy value of the bark will be maximized with the unique and further developed HQ-Press bark press and BioCrusher solution.
Start-up of the new plant is scheduled for the fourth quarter of 2025.
