초록

The objective of this study is to assess the possibility of ozone as an environmentally friendly new deinking alternative for conventional deinking method. Ozonization could removed the ink particles above 300 microns and improved the ink removal efficiency. Ozonization also improved the WRV of recycled fiber and apparent density, scott bond strength, breaking length, double fold and tear index. Thus, we believe that ozonization could be used as a deinking means of white ledger instead of conventional deinking method.
