A field test with Benzotar, an industrial residue, as a wood preservative
1985 - IRG/WP 3349
Benzotar, a residue of production of benzoic acid, was tested in field as a wood preservative. Results, after 6.5 years of exposure, showed that this product presents properties that improve the performance of wood in ground contact. This paper describes these results and presents a discussion an some aspects of its potential utilization in Brazil....

Electrodialytic remediation of a soil from a wood preservation industry polluted by CCA
1998 - IRG/WP 98-50101-14
Soil contamination is often found at wood preservation sites due to spills, dripping of excess preservatives and deposition of sludge associated with dissolved salts of copper, chromium and arsenic (CCA). The electrodialytic process is a promising heavy metal soil remediation technique. It is based on a combination of the electrokinetic movement of ions in soil with the principle of electrodialysi...

Wood preservation sites polluted by CCA. Is potassium diphosphate incubation a catalyst for the electrodialytic remediation of these soils?
1998 - IRG/WP 98-50106
As part of an evaluation of a newly developed electrodialytic soil remediation technique, we investigated the incubation of a contaminated soil (from a Portuguese wood preservation site polluted with CCA) with potassium diphosphate as a possible catalyst for the removal of heavy metals and metalloids. A chemical sequential extraction scheme (SE) applied to the soil has shown that the potassium dip...

Characterization of waste from Pinus radiata generated during industrial thermal-treatment
2016 - IRG/WP 16-20586
The thermal-treatment is an established chemical-free process to modify wood, improving the durability and physical properties of wood through its service life. During the hydro-thermolysis several reactions from wood components occur, releasing volatile and non-volatile compounds from wood to the chamber. Once the process is accomplished, solid residues agglomerate below the wood load and gaseous...

Study of the effect of extractives on the natural durability of Eucalyptus bosistoana wood
2018 - IRG/WP 18-10928
Wood as a natural material is degradable both by biotic deterioration agents (fungi, bacteria, marine borers, insects) and abiotic (UV and IR radiation, moisture, fire, etc.). The inherent resistance to the attack of the deteriorating agents is defined as the natural durability of the wood. This is an important property when considering the shelf life of wood products exposed to extreme conditions...

Engineered wood constructions in Brazil: the challenge of protection against biodeterioration for market growth
2019 - IRG/WP 19-40878
This paper presents some thoughts about Brazilian wood constructions market regarding to biodeterioration and protection against biodeterioration, especially termites. Despite of being a forestry country, there is no tradition in wood engineered buildings and some prejudice must be overcome. New companies are interested in this market and as a continental country, different problems regarding of...
