Audits show improvements in energy conservation
At Reisholz Mill, a shoe press was installed in Paper Machine 2, leading to 30% decrease in steam consumption (from 3.5 GJ/tonne to 2.3 GJ/tonne in 2001); since with less moisture remaining in the paper after the pressing phase, less energy is needed in the drying phase.
At Veitsiluoto Mill, process water is now heated with secondary heat from the bleaching plant. This improvement has led to annual energy savings of 350 TJ.
At Hylte Mill, annual NOx emissions were reduced by more than
11 tones, through improvements in the oil and natural gas burners of Boiler 2 that eliminate excess air.
