(2016). Valorization of corn stalk by the production of cellulose nanofibers to improve recycled paper properties. BioResources, 11(2), 3416-3431.1930-212610.15376/biores.11.2.3416-3431https://hdl.handle.net/20.500.14352/88917Corn stalk, an agricultural waste, was valorized by the production of cellulose nanofibers (CNF), which were tested for improving recycled paper properties. CNF from eucalyptus kraft pulp (E-CNF) was used as a reference. Addition of 0.5% wt. CNF produced from corn organosolv pulp (C-CNF) to recycled paper increased the tensile index by 20%, whereas the same improvement with E-CNF was achieved at 1.5% wt. Tensile index was further enhanced by increasing the E-CNF, whereas C-CNF achieved its maximum effect at this dose. Different recycled furnish compositions were studied to evaluate C-CNF as a product additive. C-CNF improved tensile strength in all the different recycled furnishes studied. The tensile index improvement caused by C-CNF did not depend on the proportions of old newspaper and old magazine paper used. Addition of C-CNF to recycled corrugated board fluting increased the tensile strength, but to a slightly lower extent than in the case of recycled newsprint paper.engAttribution-NonCommercial-NoDerivatives 4.0 Internationalhttp://creativecommons.org/licenses/by-nc-nd/4.0/journal articlehttps://doi.org/10.15376/biores.11.2.3416-3431open access66CNFCorn stalkAgricultural wasteRecycled paperNanocellulosePaper propertiesIngeniería químicaIndustria del papelResiduos3303 Ingeniería y Tecnología Químicas
