PROCESSING OF WOOD FIBRE FRACTION

摘要

The invention is based on performing, in an alternative step, biological or biochemical processing on a wood fibre fraction generated in connection with pulp making and unsuitable for paper making, whereby one or more biocatalysts having a disintegrating influence on the structure of wood fibres and wood fibre bundles are added to the fraction for weakening the bonds between the wood fibres. The fraction is subjected to physical processing whereby, as a consequence of the physical processing, at least some of the wood fibres processed with a biocatalyst or not processed with a biocatalyst gellify, forming a gel-like pulp. The method then comprises recovering the formed gel-like pulp.
