Firs and pines dominated the global picture of the raw materials for paper industry until the 1950s. At that time, the interest in introducing new species, mostly hardwoods, led the researchers intensify efforts to look ...

The burning of wood generate a significant amount of ash, where the main nutrient found is the calcium present in the form of quicklime (CaO) which gradually becomes calcium carbonate (CaCO3) and to add water to the lime, ...

In this paper we investigate the influence of extractives, lignin and holocellulose contents on performance index (PI) of seven woods used or tested for violin bows. Woods with higher values of this index (PI = root MOE/rho, ...

We focused in selecting four fungi, naturally living in Eucalyptus sp. fields, for application in accelerating stump decay. The wood-rot fungi Pycnoporus sanguineus (Ps), Lentinus bertieri (Lb) and Xylaria sp. (Xa) were ...

Technical lignins derived from kraft, organosolv, soda, and ASAM pulping as well as a fermented lignosulfonate from a sodium sulfite process have been subjected to oxidative ammoniation (ammoxidation) aimed at producing ...

This study aimed to evaluate the decay potential of fungi isolated from plantations of Eucalyptus spp. for biological stump removal. Therefore, an accelerated decay test was performed with fungi isolated from stumps of ...

Thermal treatment (thermal rectification) is a process in which technological properties of wood are modified using thermal energy, the result of Which is often value-added wood. Thermally treated wood takes on similar ...
