Laboratory evaluation of borate amine: Copper derivatives in wood for fungal decay
2010 - IRG/WP 10-30543
The aims of this study were to evaluate borate: amine: copper derivatives in wood for fungal decay protection as well as the permanence of copper and boron in wood. Wood treated with each of four derivatives of borate:amine:copper prevented fungal decay. Disodium tetraborate ecahydrate (Borax):amine:copper derivatives with retentions of 0.61 to 0.63% after water leaching prevented decay by Gloeo...

Using plant oils as hydrophobic substances for wood protection
2010 - IRG/WP 10-30550
The increased interest to use oils as hydrophobic agents and the current debate about the further use of creosote emphasises the urgent need of better understanding of plant and other oils as wood protectors. The present study sheds light on the hydrophobic properties and distribution of various plant oils in the anatomical structure of Scots pine sapwood. Oil retentions from approximately 70 to 5...

Wood Protection in Croatia – Situation from the Acquisition of Independence till Today
2010 - IRG/WP 10-40501
In the last eighteen years in Croatian wood-working industry, respectively wood protection industry, many good changes happened. In such a short period of time Croatian industry changed their “product philosophy”. After the fatherland war and acquisition of independence the most logs and sawn wood products have been exported from Croatia. With such “kind of philosophy” Croatian wood-workin...

Ecological methods and products for wood protection used for restoration and conservation of built heritage cultural assets to increase natural durability and duration of exposure in open air museums
2010 - IRG/WP 10-40506
Wood is a perishable material, hygroscopic and fuel, which cause attention to selecting the wood species that is going to be exhibited in relation to humidity and soil. With variable depending on its humidity and moisture from the atmosphere or soil, wood is a good living environment for fungi and insects, but suffer biodegradation processes and dimensional changes. Observations over time on wood ...

Towards designing eco-friendly buildings with in-built termite protection
2010 - IRG/WP 10-50273
The increase in greenhouse gases, leading to global warming, is considered by a consistent scientific worldview not due to natural variation, but due to the growing concentration of carbon dioxide (CO2), methane (CH4) and other atmospheric pollutants. Global emissions of carbon dioxide from fossil fuel combustion and cement production rose from 22.6 billion tons in 1990 to an estimated 31.2 billio...

Fungal biodegradation of CCA-treated wood wastes
2011 - IRG/WP 10-50276
Fungal biodegradation could be employed as a pretreatment method to alleviate problems caused by landfill disposal of CCA-treated wood wastes (e.g. a shortage of landfill space and a release of leacheate). It could be used to decrease the volume of waste and to remove metals from waste simultaneously. We have screened hundreds of decay fungi, including fungi isolated from CCA-treated wood in servi...

Decay resistance attributes of teak (Tectona grandis L. f.) wood: comparison of the fungicidal activities of quinones
2011 - IRG/WP 11-10752
The implication of quinones in decay resistance of teak wood is controversial. To better understand the role of individual quinone in this property, we studied the correlations between this latter and the content of 2-(hydroxymethyl)anthraquinone, tectoquinone, anthraquinone-2-carboxylic acid, 1,4-naphthoquinone, lapachol and the new compound 4’,5’-dihydroxy-epiisocatalponol found in teak wood...

Measuring fungal cellulolytic enzyme activity in degrading wood
2011 - IRG/WP 11-10753
An enzyme assay which measures enzyme activity directly from wood will assist in the fundamental understanding of the enzyme components of the decay mechanism of rot fungi and any changes in the presence of wood protectants. At present, to measure fungal carbohydrate degrading enzyme activity in the presence of wood, two methods are used: either 1) the enzyme is measured in the growth media contai...

Quantification of four dark colored mould fungi by real time PCR
2011 - IRG/WP 11-10754
Coated wooden claddings in building facades are widely used in the Scandinavian countries, and are often preferred to other materials. Wood is facing increasing competition from other materials that are less labor intensive at the construction site and materials with less demand for maintenance thru service life, and makes further development of wooden claddings essential. Growth of discoloring mo...

Wood protectors sensitivity of Fusarium circinatum, a quarantine organism in Europe
2011 - IRG/WP 11-10755
In the last decade, two new organisms with a high potential damage in Conifer forests have been detected in Europe. They are the nematode Bursaphelenchus xylophilus and the fungus Gibberella circinata (anamorf: Fusarium circinatum), and have driven the European Union to protect the stands from propagation and dispersion of these new pathogens.
The nematode was detected first in Setubal (Portugal)...

Characterisation and evaluation of various chitosan oligomers, and decay resistance
2011 - IRG/WP 11-30562
Chitosan, a polymer of D-glucosamine, is known for its antimicrobial activity. However, the physicochemical properties of chitosan depend upon three principal factors, i.e. source of raw material, molecular weight and degree of deacetylation. Here, we report synthesis and characterization of chitosan oligomers prepared by deaminative depolymerization of chitosan (s) obtained from Sigma Aldrich and...

Tannin resin-boron for outdoor wood protection and fire retardancy
2011 - IRG/WP 11-30567
Boron in the form of boric acid is well known for its efficacy against wood destroying organisms, as well as for its high leachability from treated wood when in outside exposure. Moreover, due to the European directive 2008/58/EC, boric acid is only authorized at low levels. In order to keep considering boric acid as an interesting active ingredient for wood protection, the issue is now to fix it ...

Design, synthesis, characterisation and effectiveness of ‘Locked-in-Boron’ chemicals for H3.2 level of wood protection
2011 - IRG/WP 11-30577
Boratrane molecules with five-membered and six-membered molecular ring systems, and with various ring substituents were synthesised, characterised and formulated for wood treatment for accelerated laboratory bioassays using wood decay fungi as test organisms. Six-membered ring boratranes showed lower efficacy in laboratory assays than five-membered ring boratranes. One alkyl-substituted boratran...

The resistance to Basidiomycetes fungi of chipboard 35 years after their industrial preservation with wood preservative on fluoroborate basis
2011 - IRG/WP 11-40546
The research on wood-based panels’ (WBP) behaviour towards fungi impact demonstrated rather low resistance of wood-based materials to wood rotting fungi. However, these materials are used in construction under conditions favourable to fungi growth. In such conditions WBP treated with wood preservatives should be used. Preservation durability is of great importance in such cases. The resistance o...

Evaluation of an optimized industrial process aiming to improve the natural durability and mechanical behavior of bamboo for outdoor use
2011 - IRG/WP 11-40554
Mao Bamboo (Phyllostachys pubescens) is characterized by high contents of sugar and starch and by high hygroscopicity, which makes it susceptible to biodegradation, and specifically to fungal decay. Still, many bamboo based products regularly enter the European wood construction market, competing with traditional solid wood products used for outdoor decking and cladding. The performance of a heat ...

2011 - IRG/WP 11-40571
The performance of zinc borate (ZB)-treated oriented structural straw board (OSSB) against mold fungi, decay fungi and termites was examined in standard laboratory evaluations. OSSB was fabricated with split wheat straw and diphenylmethane diisocyante (pMDI) resin. The ZB was added during panel manufacture to achieve preservative levels (wt.%) of 1.0%, 1.5%, 2.0%, and 3.0%. Untreated (0.0% ZB) OSS...
