Neutral Deinking Process Optimization and Comparison with Alkaline Deinking of Old Newsprint
Advanced Materials Research, 2011Pulping 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.

The Optical Properties of Deinked Pulp
Journal of Imaging Science and Technology, 2005Optical properties of handsheets made from pulp resulting from deinking flotation of multicolored and desaturated prints from digital and conventional offset printing have been observed. The prints were made on different models of digital offset machines.

Application of Deinking Selectivity in Evaluating the Deinking Performance of Flotation Equipments
Advanced Materials Research, 2012A 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.

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 ...

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, 1999Abstract 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.

Deinking of newsprint by flotation method
2023There 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

Flotacijski deinking uredskog papira
2000Recikliranje otpadnog papira jedan od važnih čimbenika u zaštiti okoliša. Na taj se način racionalizira korištenje prirodnih resursa, reduciraju se velike količine krutog otpada(novine, časopisi, ambalaža, uredski otpad).Svrha ovog rada je prikaz specifičnosti uredskog otpada u kontekstu postupka reciklaže i analiziranje karakteristika recikliranih ...

New process engineering for deinking
2004Possibilities to develop the deinking process towards an easier detachment of inks, optimal fragmentation of inks and a less wearing process for the wood fibres were studied. Work was done to optimise the use of deinking chemicals with different raw material and deinking processes, taking under consideration new technologies and the energy consumption.
