CA 2243294

The use of fermented sugar beet pulp for making paper or cardboard is disclosed as well as a fermented sugar beet pulp composition produced according to a method which comprises the steps of (a) storing the sugar beet pulp under conditions suitable for lactic acid fermentation, particularly until the pH is less than around 5 and advantageously higher than around 3.5, to give fermented pulp, (b) diluting the fermented pulp, particularly until its dry matter content is of around 1-10 %, (c) mechanically processing the diluted fermented pulp to separate the parenchymal cells from the pulp and achieve a pulp size of less than around 1000 micrometers, and (d) optionally bleaching the fermented pulp from step (a) simultaneously with step (b), or bleaching the fermented pulp from step (c).

L'invention concerne l'utilisation de pulpes de betterave à sucre fermentées pour la préparation de papier ou de carton. L'invention concerne également une composition de pulpes de betterave à sucre fermentées telle qu'obtenue par le procédé comprenant les étapes suivantes: a) on ensile des pulpes de betterave à sucre dans des conditions appropriées pour donner lieu à une fermentation lactique, et notamment jusqu'à ce que le pH soit inférieur à environ 5 et avantageusement supérieur à environ 3,5 pour obtenir des pulpes fermentées, b) on dilue les pulpes fermentées, notamment jusqu'à ce que la teneur en matières sèches soit d'environ 1 % à environ 10 %, c) on soumet les pulpes fermentées diluées à un traitement mécanique, notamment un cisaillement, permettant de séparer les cellules parenchymales contenues dans les pulpes et d'obtenir une dimension des pulpes inférieure à environ 1000 micromètres, d) on soumet éventuellement: les pulpes fermentées obtenues à l'issue de l'étape a) à un blanchiment simultané à l'étape b), ou les pulpes fermentées obtenues à l'issue de l'étape c) à un blanchiment.
