Waste papers(MOW and ONP) were deinked with alkaline cellulolytic enzyme from Coprinus cinereus 2249. The effectiveness of alkaline enzyme on sticky contaminant removal and bleaching of recycling pulp was investigated. The conclusions obtained from the results are as follows. The brightness of deinked pulps MOW and ONP was most high in 0.4IU enzyme treatment. circled2 The removal effect of sticky contaminant was enhanced with alkaline cellulolytic enzyme treatment. Bleaching with sodium hydrosulfite was most effective in one and two stage bleaching after enzyme treatment of mixed wastepaper of MOW and colored paper. circled4 The brightness of alkaline enzyme deinked ONP was increased 20％ with $H_2O$$_2$ bleaching.
