Enzymatic Hydrolysis of Waste Office Paper Using Viscosity as Operating Parameter
Biotechnology Progress, 2001AbstractEnzymatic hydrolysis of waste office (WO) paper with feeding WO paper in a reactor was investigated using apparent viscosity as operating parameter. Since the apparent viscosity was correlated with the concentration of pulping WO paper, the amount of hydrolyzed WO paper was assumed by measuring the decrease in the apparent viscosity.

A pollution reducing enzymatic deinking approach for recycling of mixed office waste paper
Environmental Science and Pollution Research, 2020The efficiency of xylano-pectinolytic enzymes, co-produced by a single microbial strain Bacillus pumilus, was analysed for the recycling of mixed office waste paper through deinking and compared with the alkaline chemical deinking method. Enzymes showed maximum deinking at pH 8.5, pulp consistency of 10%, xylanase-pectinase dose of 12 and 4 IU per gram

Comparison of morphological properties waste paper fibers from newspaper and office paper types
Известия СПбЛТА, 2023Представлены сравнительные результаты научных исследований структурно-морфологических свойств макулатурной массы после флотации с предварительным мокрым и сухим роспуском. В качестве макулатуры использовалась газетная бумага и офисная бумага с печатью. Известно, что эти виды макулатуры существенно различаются по качеству и цене, так как бумажная масса,

Waste Management, 2015
In the present study, functionalization of mixed office waste (MOW) paper has been carried out to synthesize carboxymethyl cellulose, a most widely used product for various applications. MOW was pulped and deinked prior to carboxymethylation. The deinked pulp yield was 80.62 ± 2.0% with 72.30 ± 1.50% deinkability factor.

Waste office paper filled polylactic acid composite filaments for 3D printing
Composites Part B: Engineering, 2021Abstract Developing 3D printable waste paper based biocomposites is a potentially greener alternative to traditional waste paper recycling methods. In this paper, waste office paper (WOP) filled polylactide acid (PLA) biocomposites were prepared as filaments for Fused Filament Fabrication (FFF).

Bioconversion of waste office paper to hydrogen using pretreated rumen fluid inoculum
Bioprocess and Biosystems Engineering, 2016In this study, a microbial consortium from an acid-treated rumen fluid was used to improve the yields of H2 production from paper residues in batch reactors. The anaerobic batch reactors, which contained paper and cellulose, were operated under three conditions: (1) 0.5 g paper/L, (2) 2 g paper/L, and (3) 4 g paper/L. Cellulase was added to promote the

Study of Flotation Deinking of Old Magazine and Mixed Office Waste Paper
Advanced Materials Research, 2012The effect of flotation parameters such as flotation consistency, temperature, flotation time, air to pulp ratio, and velocity of pulp flow (turbulence level) on OMG/MOW deinking efficiency was studied by using a high-consistency laboratory pulper and a laboratory deinking cell. The optimized flotation conditions were: flotation consistency 1.1%, 40°C,

Utilization of waste office paper to reduce nitrate leaching into the Northern Guam aquifer
Biology and Fertility of Soils, 2000Rapid nitrate leaching losses due to current agricultural N management practices under the humid tropical environmental conditions of the Pacific island of Guam may contaminate fresh and salt water resources. Potential environmental contamination of the Northern Guam aquifer, which is overlain by shallow limestone-derived soils, is a major public ...

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 ...
