Based on data collected from seven commercial harvesting operations in Western Australia, the study developed a productivity model for chain flail delimber-debarker-chippers (CFDDCs) used in blue gum (Eucalyptus globulus Labill.) plantations. The tests covered 45 h and 3395 cycles, and were...

Hardwood vessel elements generate problems in industrial uncoated wood-free printing paper operation, causing vessel picking and ink refusal. These problems are mitigated using mechanical refining at the cost of paper quality. Vessel enzymatic passivation, altering its adhesion to the fiber network ...

To estimate the effect of chemical treatment of wood or typify the phenotypes of genetically modified plants, it is necessary to know the coexistence mode of wood components. Herein, the average states of carbohydrate/lignin coexistence in ball-milled and cellulase-treated wood powder samples were...

This work establishes the main guidelines to produce high-performance Eucalyptus globulus Labill finger jointed solid timber and glued laminated timber laths and analyse their potential for application in multilayer strained gridshells. To this end, a proposal for strength grading of eucalyptus...

The preservation of non-durable woods such as Ayous through the use of environment friendly products is nowadays a major concern to many tropical wood researchers. The objective of this work was to assess the potentials of Jatropha curcas oil (JCO) alone and in combination with Cymbopogon citratus...

The process of prehydrolysis followed by soda-anthraquinone (AQ) cooking and totally chlorine-free (TCF) bleaching with peroxymonosulfuric acid (P_sa) was investigated to develop a biorefinery process. Eucalyptus globulus, showing a high syringaldehyde (S_a) to vanillin (V_a) molar ratio after...

The re-profiling from paper-grade to dissolving pulp production is a common trend for acid sulfite cooking of wood. This provides substantial changes in the composition of the spent sulfite liquor (SSL) affecting its potentialities in subsequent processing within the biorefinery concept. In this...

Eucalyptus globulus Labill is an important raw material for pulpwood for which low lignin content and high S/G ratios are important parameters. This work shows a highly significant positive and strong correlation between S/G ratio and acid-soluble lignin (ASL) content among E. globulus trees....

Micro- and Nano-Fibrillated Cellulose (MNFC) have gained increasing attention due to their remarkable properties, but their production usually requires an intensive multi-step process. This study proposes to find a novel approach involving steam explosion for the production of lignin-containing...

The use of glued finger joint in green wood, directly from the sawing process, would open the possibility to obtain glued timber from small-sized wood, achieving an efficient use of the original raw material. The gluing of finger-jointed green wood, with moisture content above the fibre saturation...
