Conversion of WastePaper into Dissolving Pulp: A Path for Circular Bioeconomy

ChemistrySelect, Volume 9, Issue 30, August 12, 2024.
The potential of wastepaper to produce dissolving pulp was demonstrated in this article. By employing and optimizing chemical processes to wastepaper pulp, a noteworthy increase of 84 % in pulp Fock reactivity was achieved (from 45.6 % to 84.1 %). The pulp characteristics were followed throughout the different treatments allowing better understanding ...

Effect of Electron Beam Irradiation on the Properties of Softwood Unbleached Kraft Pulp

Journal of Korea Technical Association of The Pulp and Paper Industry, 2015
Electron beam irradiation is also an eco-friendly treatment compared to other physical and chemical treatments. In this study, we attempted to evaluate the possibilities of energy savings by applying electron beam irradiation to the refining process. After softwood unbleached kraft pulp (UKP) was irradiated with electron beams at 50 and 100 kGy, it was

Fiber Modification of Unbleached Kraft Pulp with Laccase in the Presence of Ferulic Acid

BioResources, 2013
Unbleached kraft pulp fibers were modified with laccase and ferulic acid (FRC) to improve their physical strength properties in paper products. The optimal conditions of laccase-FRC modification were examined in terms of the physical properties of pulps. The effects of laccase-FRC modification on the carboxyl group content and surface lignin content of

The Effect of Packaging Types on Fresh Peaches in the Direct‐To‐Consumer Environment: Distribution Testing, Life Cycle Assessment and Economic Impact

Packaging Technology and Science, Volume 37, Issue 7, Page 667-684, July 2024.
This study evaluated different package types' sustainability, cost and protective capacity on peaches in the direct‐to‐consumer distribution environment. The vibration response of peaches in all package types is amplified in the same frequency region as the input from truck‐trailer systems, and damage from shock events is correlated with the freedom of

Using Paper as a Biomimetic Fog Harvesting Material

Advanced Materials Interfaces, Volume 11, Issue 8, March 14, 2024.
Paper materials are turned into biomimetic fog harvesting surfaces by applying a superhydrophobic coating with hydrophilic glass particles. The combination of the optimal water‐draining superhydrophobic background with smooth pinning centers provides superior fog harvesting potential, especially compared to model substances (glass, polyethylene, and ...
