The aim of the present work was to find a suitable Kraft cooking process for olive tree pruning (OTP), in order to produce pulp of kappa number about 17. The Kraft pulp produced under optimized conditions showed a viscosity of 31.5 mPa·s and good physical, mechanical, and optical properties, which are suitable for paper production. The physical-mechanical and optical properties were measured be...

Paper furnishes often contain a mixture of a weak pulp with relatively short fibers and a strong pulp with relatively long fibers. Whereas increased proportion of the long-fiber pulp can be expected to impair formation, it has been unclear to what extent a change in formation through the pulp ratio affects the strength efficiency. (Strength efficiency is a measure of how well the strength poten...

INTRODUCTION Arundo donax, Poaceae, commonly known as “nalgrass,” is a member of the reed family that grows both wild and cultivated in California. Evaluated as a potential paper fiber source in Italy and Hungary over 50 years ago and included in the 1970s USDA evaluation of potential annual fiber crops, the high potential of A. donax has not been widely recognized. A new evaluation was begun i...

Abstract Addressing solid waste recycling, this study aims to develop biodegradable kraft paper from buffing dust (BD) and post‐consumed jute fiber (JF). Employing a simple solution casting method with polyurethane binder, the was fabricated characterized using UV–Vis spectroscopy, FTIR, XRD, SEM, TGA, OTR, biodegradability, tensile tests. The findings revealed covalent hydrogen bonding between...

The Multi-Criteria Decision Analysis (MCDA) procedure was used to compare waste management options for kraft pulp mill sludge following its anaerobic digestion. Anaerobic digestion of sludge is advantageous because it produces biogas that may be used to generate electricity, heat and biofuels. However, adequate management of the digested sludge is essential. Landfill disposal is a non-sustainab...

This work offers a comprehensive understanding of the conditions required for the selective masking of the phenolic hydroxyl groups in technical kraft lignins, which is pivotal in determining their subsequent chemical and thermal reactivity. To this effect, we have examined the chemistry and developed the conditions for the facile, mild, and selective masking of the phenolic hydroxyl groups in ...
