A process for treating lignocellulose pulp using a preparation containing at least one enzyme that produces a solubilizing action and, potentially, a hemicellulolytic action on lignin. The enzymes are derived from the bacterium Streptomyces viridosporus. This enzymatic treatment may be used for the separation of lignin from lignocellulose pulp in a procedure, for example, that complements a bleaching treatment.

Effluent containing inks undergoes flocculation by the action of a flocculating agent, followed by the continuous centrifuging of the effluent consisting of an acceleration between 1,000 and 20,000 g, while avoiding an air-liquid interface during centrifuging.

A biocompatible hydrophilic material is based on purified cellulose, from which material all or the majority of the water has been removed and which has a modulable potential for water recovery of up to an amount of water of approximately 60%. The material can be used for the production of fitting sheaths for articulated prostheses.

A packing paper comprising a support layer and a coating layer. The coating layer contains minerals, which give it a white pigmentation, has a content of between 25 and 50% by weight of dry materials, has a good degree of whiteness which is at least equal to 70, and has good capacity for flexographic printing.
