Abstract (en)

[origin: EP0743393A2] A paper material of excellent characteristics is produced from industrial textile waste and exhausted sugarbeet pulp, which, derived from the diffusion extraction of sucrose, is pressed to bring the dry substance to a content of 22-28%, and is stored, in the absence of chemical additives, by inducing anaerobic fermentation. Following treatment in conventional pulping facilities, or in Bi-Vis machines, or in a steam explosion facility, a paper pulp of exhausted beet pulp (2-50%) and industrial waste cellulosic textile fibers is prepared with or without papermaking additives, and the pulp is used in traditional manner to produce paper comparable with that produced using currently used chemical pulp.
