Pre-treatments reduce energy consumption for the production of cellulose micro/nanofibrils (MFC/CNF). The objective of this work was to study sodium silicate (Na 2 SiO 3 ) solutions as pre-treatment for  Eucalyptus  sp. and  Pinus  sp. pulps. The treatments were identified as  EUC SS  5 % and  EUC SS  10 % when 5 and 10 % Na 2 SiO 3  were used, respectively. The treatments for Pinus sp. pulp were identified as  PIN SS  5 % and  PIN SS  10 %, and the untreated pulps as  EUC control  and  PIN control . The lowest hemicellulose content was obtained for  PIN SS  10 %.  EUC SS  10 % showed the highest WRV values.  EUC SS  5 % (∼ 4100 kWh/t) and  EUC SS  10 % (∼ 4200 kWh/t) showed the lowest energy consumption. The pre-treated MFC/CNF showed diameters below 45 nm. The lowest viscosity was obtained for  EUC SS  5 % (5.5 cP) and the highest for  PIN control  (7.7 cP), respectively. The zeta potential indicated moderate stability of the suspensions (−24 ∼ −18 mV). Na 2 SiO 3  showed efficiency for MFC/CNF production due to reduced energy consumption and better individualization. The suspensions have compatible characteristics for application as a stabilizer of colloidal systems and reinforcement of composites.
