Thermo-chemical converting Torrefaction, pyrolysis for energy densification of biomass. Conversion to energy products (bio-fuel, bio-oil, pellets) and green materials/chemicals. Characterization Chemical and morphological of raw materials, intermediate- and end products.

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 2.0-2.5 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 %.
