In this study, first of all, pulping processes were applied on white A4 office paper which was applied laser printing. Then, mixtures were prepared in the proportions determined on the pulped office papers. In this pulping and mixture preparation process, different ratios of chemicals and enzymes were utilized. As chemical substances, oleic acid, sodium hydroxide, sodium silicate, calcium chloride and hydrogen peroxide were used and cellulase, xylanase, amylase and β-gluconase were used as enzyme. Then, ultrasound effect was examined. Finally, the pulp suspension was removed from the inks by flotation. At the end of all these processes, wastewater analysis was performed. [ABSTRACT FROM AUTHOR]
