Enzymatic deinking of laser printed office waste papers: Some governing parameters on deinking efficiency

Bioresource Technology, 2007
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 an effective method for paper recycling. A maximum deinking efficiency of almost 73% by the enzyme combination of C:H was obtained using the deinking conditions of pulping ...

Application of Deinking Selectivity in Evaluating the Deinking Performance of Flotation Equipments

Advanced Materials Research, 2012
A deinking progress selectivity concept that be expressed by deinking efficiency and pulp yield was proposed for comparing different flotation equipments or progresses. Expression of deinking selectivity was given out in the paper, which is expressed by the ratio of deinking efficiency and flotation rejection loss.

Cavitation-jet deinking: A new technology for deinking of recovered paper

TAPPI Journal, 2014
A new method and in-house device for treating secondary fiber were developed. The method is based on the fluid-jet cavitation technique. In this apparatus, pulp suspension was injected into the reacting vessel by using a high-speed jet that produced cavitation bubbles around the jet. The impact of the collapse of cavitation bubbles detached ink, binder,

Neutral Deinking Process Optimization and Comparison with Alkaline Deinking of Old Newsprint

Advanced Materials Research, 2011
Pulping parameters in neutral deinking of old newsprint (ONP) and its impacts on deinking efficiency were investigated as well as comparison with alkaline deinking was carried out in this paper. The results showed that the low pulping consistency and short pulping time mostly contributed to the removal of ink in neutral pulping stage.

Deinking of newsprint by flotation method

1995
There is much current interest in development of processes which lead to . greater utilisation of secondary fibres in papermalcing operations, both in Australia and overseas. The removal of ink from paper (deinking) is a major step in these processes. After repulping, ink can be removed from aqueous suspension by a number of techniques, one of which is

Quality of deinking sludge

Journal of Environmental Science and Health . Part A: Environmental Science and Engineering and Toxicology, 1993
Abstract A study was made of the quality of deinking sludge originating from five wood‐processing factories in four European countries in 1990. Heavy metals and polychlorinated biphenyls were the main focus of this study and their concentrations were found to be low.

Hydrodynamics of deinking flotation

International Journal of Mineral Processing, 1999
Abstract The technological parameters relating to the aeration, mixing and separation steps of the flotation cells currently used in the field of waste paper recycling are reviewed in this paper. A laboratory flotation cell was designed to study the effects of the hydrodynamic flotation parameters, and tested on different deinking furnish.
