Abstract

L'invention se rapporte à un procédé de blanchiment de pâte de cellulose, ladite invention comprenant l'utilisation d'une enzyme d'oxydation. L'invention se caractérise en ce qu'un élément métallique de transition tel que du manganèse est utilisé selon le procédé, et, lorsque cela s'avère nécessaire, le niveau du potentiel redox du procédé de blanchiment est régulé. Selon le procédé, de la laccase peut ètre avantageusement utilisée comme enzyme d'oxydation. Ledit procédé permet de réduire efficacement la consommation de produits chimiques à base de chlore dans le blanchiment de pâte de cellulose ainsi que la teneur résiduelle en composés de chlore organique des eaux usées provenant de l'étape de blanchiment.
