To achieve our target, we have defined mill-specific measures which improve water recycling and reduce water withdrawal from natural sources. Some of the projects still lack a final investment decision and the times shown are indicative. Over 50% of total process water reductions per product tonne will be due to the phase 2 of the renewal of Husum pulp mill.
