Abstract

The benefits of bio-deinking of waste paper are investigated in this study. ENZYMATIC MODIFICATION of MIXED OFFICE WASTE PAPER and OLD MAGAZINE pulps was performed at two TEMPERATUREs, 20 and 50 °C. Nonionic SURFACTANT with different hydrophile-lipophile balance values and sodium tripolyphosphate was used as the deinking agent. The deinking process was conducted for pulps with and without enzymatic treatment. The results show that, for MIXED OFFICE WASTE PAPER and OLD MAGAZINE pulps, the highest strength properties are achieved using lower hydrophile-lipophile balance at 20 and 50oC, respectively, while using higher hydrophile–lipophile balance has a significant influence on the optical properties at 50 °C. Further, the results show in the presence of sodium tripolyphosphate, the optical properties of treated pulps, especially OLD MAGAZINE pulp significantly improved at 20oC (ESST system). For MIXED OFFICE WASTE PAPER, the optimum values of burst, tear and tensile indices, folding endurance, E-MOD, tensile energy absorption and elongation are 2.97 (kPa m2/g), 7.68 (mN m2/g), 93.47 (N m/g), 13, 8024 (GPa), 100.16 (J/m2) and 2.53 (%), respectively. Moreover, the results from measuring optical properties of handsheets show that the optimum values of brightness, dirt count, dirt area and DEINKING EFFICIENCY are 44.72 (%), 11, 0.221 (mm2) and 78.07 (%) correspondingly, while for OLD MAGAZINE, the formers are 2.35 (kPa m2/g), 6.77 (mN m2/g), 77.77 (N m/g), 9, 6199 (GPa), 72.61 (J/m2) and 2.37 (%) and the latters are 60.93 (%), 1, 0.005 (mm2) and 99.52 (%), respectively.
