| Using enzyme Xylanase deinking could be carried out. Recycled waste paper has become an important and environmentally harmless source for new paper making. Office waste papers with laser prints is considerable available waste for recycling due to increased utilization of these papers. However, the reuses of these waste papers are limited. Inks are fixed by fusion with combination of pressure and heat (Carr, 1991). Moreover most of the conventional deinking techniques require usage of large amount of chemical agents such as sodium carbonate, sodium hydroxide, sodium silicate, hydrogen peroxide and surfactants (Prasad et al., 1993) which results in a costly wastewater treatment (Jeffries et al., 1994). Furthermore, enzymatic deinking is free from alkaline environments required in traditional deinking process, which consequently reduce chemical and waste treatment cost. Therefore, commercial available enzymes such as cellulase, and xylanase were attempted in present study for their efficacy. In addition the enzymatic treatment improves brightness of paper |
