Finland-headed forest industry major Stora Enso Oyj has announced that it will invest SEK 232 million (≈ EUR 22 million) at its Skoghall Mill in Sweden in an expansion of the existing wastewater treatment plant (WWTP). 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 recipient Lake Vänern. The sludge can also be used as a biomass fuel.
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 ponds 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’s also a key element of the continued development of the Skoghall Mill, said Hans Olsson, Head of Technology and Investments at Skoghall Mill.
Founded in 1917, Stora Enso Skoghall Mill in western Sweden is a modern producer of cartonboard for demanding consumer packaging and printing purposes, including liquid packaging and dry foodstuffs board. The mill has an annual capacity to produce 855 000 tonnes of cartonboard.
