Firewood and charcoal are widely used as solid fuels in thermal, mechanical, and electrical energy generation processes in Brazil. Their production comes from silviculture or extractivism. The objective of the present study is to verify whether the expansion of forestry crops, mainly of eucalyptus, ...

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...

Highly filled composites of poly (methyl methacrylate) (PMMA) and cellulose fibers with 25-75 wt. % cellulosic filler content were prepared by a flocculation/coagulation process of a mixture of a cellulose fiber suspension and PMMA emulsion. Two types of cellulose fibers, namely never dried...

The thermal degradation of the wood of two commercially used eucalyptus species from South Africa, namely Eucalyptus dunnii and Eucalyptus macarthurii was studied. Both are valuable pulpwood species and the financial loss due to wildfires each year is significant. This study aimed to understand how ...

The cross-laminated timber (CLT) construction system has recently emerged as an excellent alternative for civil construction. The objective of this work is to analyze the structural performance of CLT panels using plantation lumber, especially eucalyptus (Eucalyptus grandis) heartwood and pine (...

This article analyzes the behavior of surface finish and pressing time in glued pieces of eucalyptus wood. The importance of the study lies in verifying the influence of two variables (surface finish and pressing time) on the gluing of wood pieces for the furniture industry over time. For this...

This study assesses the possibility of obtaining regenerated cellulose products (beads and films) from eucalyptus sawdust dissolving pulps produced by non-conventional processes, compared with a commercial dissolving pulp as a reference. Eucalyptus sawdust dissolving pulps were obtained by soda...

Using the molecular dynamics software Materials Studio, a micro-level carbon dioxide - cellulose model was established to study the supercritical carbon dioxide drying of eucalyptus wood. The change of the primary components of the eucalyptus wood cellulose were also studied, by simulating various...

The use of recycled raw materials and renewable sources are necessary for economical, social, environmental and technological development. In this context, this work aims to study the influence of two lignin types, one derived from pine (Lig I) and the other one from eucalyptus, (Lig II) on polymer ...

Corymbia hybrid is a fast growing inter-specific hybrid of tree species. Physical and mechanical properties of Corymbia hybrid were evaluated in present study. Results show that mean density of Corymbia is 0.71 g/cm³ and it increases from pith to periphery. Mean radial and tangential shrinkage are...
