Abstract
The deinking experiments of waste newsprint with biological enzymes had been done to evaluate the effect of enzyme deinking and to improve the quality of regeneration of waste paper. A newsprint enzyme deinking process had been established, and the deinking samples had been prepared. The quality of deinking process was evaluated by whiteness and residual ink area percentage. The deinking effect had been compared with one-component enzyme preparation and two-component complex enzyme preparation. The results show that the best one of one-component enzyme preparation deinking is lipase, with the whiteness of 55.33 % and the residual ink area percentage of 2.11 %; two-component complex results show that the cellulase and lipase enzyme works best with the whiteness of 55.69 % and the residual ink area percentage of 1.85 %. Three enzymes all can remove ink from waste newsprint and the deinking effect could be enhanced when mixed.
