| description | The present invention relates to a process for recovering starch present in paper and/or cardboard, by: [a] preparation of an aqueous suspension A of fibres, [b] treatment of the aqueous suspension A and formation of two fractions: - fraction B containing water, fibres, fines and fillers; - fraction C containing water and dissolved and/or colloidal starch, fines and fillers, [c] separation of fraction C into two fractions: - fraction D containing water and dissolved starch, - fraction E containing water and colloidal starch, fines and fillers, [d] use or treatment of fraction D, [e] use or exploitation of fraction E.
La présente invention concerne un procédé de récupération d'amidon présent dans du papier et/ou du carton, par : [a] préparation d'une suspension aqueuse A de fibres, [b] traitement, de la suspension aqueuse A et formation de deux fractions : - fraction B contenant de l'eau, des fibres, des fines et des charges, - fraction C contenant de l'eau et de l'amidon dissous et/ou colloïdal, des fines et des charges, [c] séparation de la fraction C, en deux fractions : - fraction D contenant de l'eau et de l'amidon dissous, - fraction E contenant de l'eau et de l'amidon colloïdal, des fines et des charges, [d] utilisation ou traitement de la fraction D, [e] utilisation ou valorisation de la fraction E. |
