Stora Enso is to invest €22 million at Skoghall Mill in Sweden in an expansion of the existing water treatment plant. Increased capacity and new, modern technology will enhance the water treatment process at the mill. This will reduce the environmental impact of the operations and help to meet future environmental requirements.


In the water used in the production of cartons, small particles of wood fibre remain. By expanding the plant, the separation of sludge is improved, which in turn improves the quality of the water that is returned to the near by Lake Vänern. The sludge can also be used as biofuel.


‘We always strive to use as much of the wood as possible, to find new uses for our by-products, and to minimise our environmental footprint,’ said Margareta Sandström, environmental manager at the Skoghall Mill.


The project consists of three larger pools for more efficient sedimentation, along with associated process and control systems. Work is due to start immediately and is expected to continue until early 2020. 


‘This is another example of an environmentally sustainable investment which, even at start up, has a direct positive impact. It is also a key element of the continued development of the Skoghall Mill,’ said Hans Olsson, head of technology and investments at Skoghall Mill.
