Abstract
The objective of this study is to assess the possibility of ozone as an environmentally friendly new deinking alternative for conventional deinking method. It is well known that the white ledger is very difficult to deink because the toner ink has the peculiar shape and size. Ozonization could remove the ink particles above 300 microns and thus 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 the convention미 deinking method.
