Papir- og fiberinstituttet AS Paper and Fibre Research Institute Energy reduction in pulp and paper processes Reduced electrical energy consumption: Norske Skog consumed 7.7 TWh electricity during 2010 and most of this was used in the thermo-mechanical pulping process (TMP). In the TMP process, fibres are separated and developed and at the same time steam is produced. About 50-60% of this steam can be used for drying the paper on the paper machine. PFI has together with Norske Skog and Andritz developed a new process called ATMP (Advanced TMP) where at least 25% of the electrical energy consumption can be reduced. Implemented, the new technology would reduce the electrical consumption in Norske Skog with TWh annually. In the ATMP process, new process stages are introduced and chemicals are used to facilitate the fibre development. Reduced heat consumption: Drying of paper requires huge amounts of steam energy and through furnish engineering, the energy consumption suring drying of newsprint has been lowered by 7 %.
