Stora Enso's main environmental parameters continued to develop favourably during 2001.
Discharges into water declined in absolute terms as follows:
COD by 38 700 tonnes; AOX by 170 tonnes; Nitrogen by 260 tonnes; and Phosphorus by 40 tonnes. In specific terms, expressed as kg/tonne of products, these figures correspond to reductions of 13% for COD, 15% for AOX, 5% for Nitrogen, and 3% for Phosphorus. The greatest improvements in discharges into water were recorded at Skutskär Mill, where a new external treatment plant has recently been installed. View trends.
Emissions into air of NOx and Sulphur dioxide declined by 2 200 tonnes and 1 700 tonnes, respectively. In specific terms, expressed as kg/tonne of products, these figures correspond to a reduction of 3% in NOx emissions, and an increase in Sulphur dioxide emissions of 2%. The rise in the relative emissions of Sulphur dioxide was largely due to the use of fossil fuels for intermittent energy production during periods with frequent interruptions in production. Another factor was the increase in the production of Combined Heat and Power (CHP), also involving fossil fuels. View trends.
The disposal of solid waste has been reduced by 41 000 tonnes overall, with particularly remarkable improvements reported from Wisconsin Rapids Pulp Mill and Skoghall Mill. View trends.
