Water Water is a priority for SCA because pulp and paper mills use large volumes. The Group has set new targets for reducing water usage in water-stressed areas, and for ensuring that only high quality, treated water leaves the mills. We aim to achieve water sustainability and we will reduce our water usage in water-stressed regions by 10% by 2015, with 2010 as reference year. All SCA pulp and paper mills will employ mechanical and biological water treatment plants by 2015. Outcome 2013 By year-end 2013, water usage in water-stressed regions in relation to the production level had declined by 10.4%, compared with the reference year of 2010. Of the Group’s 44 pulp and paper mills, mechanical and biological effluent treatment systems have been installed at 42 plants.
