It included the production of 170 g/m2 paperboard, using mixtures of short-fiber and long-fiber fractions from recycled pulps with typical mill additives. In all cases, 3 wt. % of nanocellulose was added to the pulp suspensions. The first scenario involved three types of nanocellulose addition in a mixture of 78 % long-fiber/22 % short-fiber pulps. The second scenario included the addition of two types of nanocellulose to an unrefined long fiber pulp to produce a multilayer paperboard. Drainage time and physical-mechanical properties of the handsheets were evaluated. Nanocellulose improved the mechanical properties in all cases. The tensile and burst indexes increased 19 % and 28 % in Scenario 1 and up to 60 % and 43 % in Scenario 2, respectively. The lower values in mechanical properties for Scenario 1 were attributed to the effect of the retention system. A new retention system using a cationic polymer with a high charge density produced decreases up to 79 % in the drainage time. 2023 artículo científico 0717-3644 https://www.redalyc.org/articulo.oa?id=48575202039 https://www.redalyc.org/journal/485/48575202039/ https://www.redalyc.org/journal/485/48575202039/html/ https://www.redalyc.org/journal/485/48575202039/48575202039.epub https://www.redalyc.org/journal/485/48575202039/movil 10.4067/s0718-221x2023000100437 en http://www.redalyc.org/revista.oa?id=485 Maderas.
