This study assesses the possibility of obtaining regenerated cellulose products (beads and films) from eucalyptus sawdust dissolving pulps produced by non-conventional processes, compared with a commercial pulp as reference. Eucalyptus were obtained soda pulping followed two TCF sequential bleaching processes OOpZ, OOp, cold extraction. The characterization involved alpha-, beta- gamma-cellulos...

Three approaches were examined for the reutilization of cold caustic extraction (CCE) lye. The term CCE lye refers here to used NaOH solution with relatively high alkali content, which could be wasted if not reused properly. results showed that can effectively applied in deinking, alkaline hydrogen peroxide bleaching, and oxygen delignification processes. improved physical strength dried sheet ...
