A method for the manufacture of paper products includes the feeding of a carbon dioxide stream to a product flow which includes a material containing an aluminum compound. The material is preferably wastepaper containing aluminum sulfate or papermaker's alum. The material may also be a product flow of wastepaper (containing aluminum sulfate) to which a supply of virgin pulp has been added. The carbon dioxide addition to the product flow reduces the pH of the product flow to a level of acidity which allows a dissolution of the aluminum compound and incorporation thereof throughout the product flow.

Un procédé de fabrication de produits du papier consiste à envoyer un flux de dioxyde de carbone dans un circuit de produit contenant une matière renfermant elle-même un composé de l'aluminium. La matière est de préférence du vieux papier renfermant du sulfate d'aluminium. La matière peut également être un circuit de vieux papier (contenant du sulfate d'aluminium), auquel on a ajouté de la pâte vierge. L'addition de dioxyde de carbone au circuit de produit réduit le pH du circuit à un niveau d'acidité qui permet la dissolution du composé de l'aluminium et son incorporation dans le circuit de produit.
