Abstract
This paper reports on bleaching of mixed office waste using a high tem perature hydrogen peroxide bleaching process. With this process - in c ombination with hydrosulphite or FAS - it is possible to bleach MOW-co ntaminated with colored ledger, mechanical pulp and OCC fibres to brig htness levels well over 80% ISO and, simultaneously obtain a low color shade of bleached pulp.
