Wood preservative obtained by recycling – preliminary selection of leaching inhibitor
2008 - IRG/WP 08-50252
Based on recycling of used household batteries, a process was developed to enable the recovery of major manufacturing components, leading to a solution of zinc (32 g.l-1) and manganese (15 g.l-1) salts, free of heavy metals. The potential use of the above solution as wood preservative was demonstrated by means of assays both of fungicidal activity -using white and brown rot fungi- and of insectici...

Effect of Heavy Metals on the Expression of Manganese Dependent Peroxidases of Phanerochaete chrysosporium
2010 - IRG/WP 10-10722
This work is part of an ongoing investigation that studies the application of a solution rich in Zn and Mn, obtained from a recycling process, as a preservative for wood. The effects of Zn2+ and Mn2+ on the enzyme-expression level of manganese-dependent peroxidase (MnP) from Phanerochaete chrysosporium was studied by real-time PCR. The glyceraldehyde 3-phosphate dehydrogenase gene (gpd) was used a...

Ammoniacal zinc borate as solid wood preservative
2014 - IRG/WP 14-30659
Zinc borate, well-known for its fungicidal, insecticidal and flame resistant properties, is widely used in manufacture of lignocellulose particle board. This form of borate is the least water soluble form available providing advantages as well as disadvantages for use as a wood preservative. This form does not leach from wood under conditions of high humidity, but it is also very difficult to appl...

Five-year evaluation of a field trial of Eucalyptus grandis poles treated with zinc and boron
2017 - IRG/WP 17-30721
Round Eucalyptus wood treatment in sequential stages with inorganic borates and metal salts (zinc sulfate and boric acid+borax) was studied; the aims were to form an insoluble precipitate of zinc borate inside wood and to reduce treatment costs by performing the first treatment by simple ascent and diffusion of the preservative, at the same time as it was sought to impregnate the heartwood. The se...
