N2 - The enzymatic deinking process was developed in two stages, the first one was the enzyme pretreatment and the second one the subsequent flotation deinking, both conducted at pH = 5.5 and temperature = 55°C. Other process parameters were: enzyme concentration = 1545.96 FPU, air flow rate of 0.5L/min, and Na2SiO3 concentration of 48.65 Be. The optimal deinking conditions were: Enzyme dosage of 0.15%, enzymatic action time of 20 min, flotation consistency of 0.5%, whereby the 70% of essays reached ISO brightness over 70%, with a maximum value of 80% and an average yield of 90%.
