The mechanical strength degradation of recycled paper (RP) caused by the keratinization of recycled fibers is a basic problem to be solved urgently in the waste paper recycling industry. Compensating RP strength in a sustainable pathway is imperative and challenging. Cellulose nanofibrils with a three-dimensional interpenetrating network structure (3DIPN-CNFs) developed as a new family of strength additives for RP were demonstrated herein. The 3DIPN-CNFs were obtained from bagasse in a single bath treatment with H
3 PO4 and H2 O2 under mild aqueous conditions. The tensile index and tear index of the RP with 3DIPN-CNFs were increased by 78% and 39%, respectively. 3DIPN-CNFs are less expensive and easier to obtain than Isolated-CNFs because homogenizing mechanical treatment is not required and are expected to become a sustainable strength additive for RP.
