The combined de-inking technology of ultrasonic, UV irradiation and enzymatic methods
was introduced into the de-inking process of HP laser printed paper. The purpose was to …

Waste paper recycling has increased dramatically in recent times, and will continue to do so
in the foreseeable future. Ink removal constitutes one barrier to converting this raw material …

Aims: It is recognized that laser printed paper are difficult to deink using conventional
method. This had lead to the suggestion of enzymatic approach to overcome the problem …

This paper reports the effects of multipass laser ablation over large areas and single lines of
multiple layered coloured inks which have been printed upon ordinary white wood pulp …

This work investigated the effect of a chelator-mediated bio-mimetic free radical treatment on
repulping and flotation operations during the deinking of laser printed copy paper. A chelator …

Colored offset newsprint was deinked at low pH with several enzyme preparations
containing cellulases and hemicellulases. Brightness, freeness, and strength properties …

The protocol for the enzymatic deinking of laser printed waste papers on a laboratory scale
using cellulase (C) and hemicellulase (H) of Aspergillus niger (Amano) was developed as …

The aim of the present study was to characterize the enzymatic deinking of various types of
waste paper. Studies on the optimization of enzymatic deinking have been performed …

This paper reports the effects of laser ablation upon multiple-layered coloured inks which
have been printed on an ordinary white paper. The aim of this work is to examine the …

The performance of a newly developed pilot scale continuous enzymatic deinking system
has been evaluated using a mixture of cellulase and xylanase enzymes in the deinking of …
