What molecular biology can tell us about the biodegradation of lignocellulose: the utilization of molecular techniques for the detection, identification and enhanced understanding of wood degrading organisms
2013 - IRG/WP 13-20528
Molecular techniques are now routinely used in the identification, detection and analysis of wood degrading organisms. An overview of some of the early work on nucleic acid isolation and characterization will be followed by a discussion of the power of sequencing and other procedures for better understanding: the mechanisms involved in the biological degradation of wood, the metabolic basis of pre...

Performance of untreated wood and wood impregnated with copper-ethanolamine based preservative solutions in Northern Adriatic Sea
2013 - IRG/WP 13-30623
Sea water applications of wood are among the most challenging ones. Impregnated wood is exposed to leaching and to variety of marine borers, Limnoria sp. and Teredo sp. being the most important. In the present research, durability of pine wood impregnated with copper-amine based preservative solution (Silvanolin) of different concentrations, exposed to the sea water, was investigated according to ...

Marine Borer Resistance of Acetylated and Furfurylated Wood – Results from up to 16 years of Field Exposure
2016 - IRG/WP 16-40756
Furfurylated and acetylated Scots pine sapwood has been tested since 1999 in a marine field with high marine borer activity. In 2004, two test groups with acetylated southern yellow pine (product later known as Perennial Wood™) were put out and over the whole test period differently furfurylated wood (later marketed as Kebony®) test groups have been started. Furthermore, some combinations of mo...

Hibernation or spring awakening? – The research on wood durability and protection in marine environment
2018 - IRG/WP 18-10929
Wooden structures in marine applications are exposed to severe degradation conditions caused by mechanical loads and wood degrading organisms. The present paper presents the use of wood in marine environments in Europe from a wood protection perspective and gives an overview over relevant research topics. It compiles the most relevant literature with an emphasis on new wood protection methods and ...

Resistance against marine borers: About the revision of EN 275 and the attempt for a new laboratory standard for Limnoria
2020 - IRG/WP 20-20669
Wood protection technology in the marine environment has changed over the last decades and will continue to do so. New active ingredients, newer formulations, and novel wood-based materials including physically- and chemically-modified wood, together with increasing concerns over environmental impacts of wood preservatives, urgently demand a major revision of EN 275 “Wood preservatives – Deter...

Validating a short-term laboratory method to assess the resistance of timber to biodegradation by marine wood-borers
2021 - IRG/WP 21-10975
Novel approaches to protecting wood in coastal and marine environments are needed as the use of traditional broad-spectrum biocides are now restricted. Wood is widely utilised in marine environments where it can be rapidly degraded by wood-boring organisms, causing billions of dollars of damage per annum. Biocidal compounds such as CCA and creosote have been popular treatments for timber products ...

Experience Experience from over 20 years of field trials of resin treated wood – Marine borer resistance of MMF and DMDHEU modified wood
2021 - IRG/WP 21-10976
In 1999 a field test of Scots pine treated with MMF (Methylated Melamine Formaldehyde) resin and acetylated Scots pine post treated with MMF resin was started. Six years later a commissioned full NWPC test for BASF of Belmadur® (DMDHEU resin treated wood) was started at the same site.
The testing, according to European Standard EN 275, was done in a bay by Kristineberg Marine Research Station o...

Field tests of different tropical wood species in sea water
2022 - IRG/WP 22-30773
A number of tropical timbers have been tested according to EN 275 at Kristineberg Marine Research Station in Sweden since 1999. Most of these tests have started during the last 5-8 years.
Wood species included have been Lophira alata (Azobé/Ekki), Minquartia guianensis (Manwood/Acaria), Chlorocardium rodiei (Greenheart), Cyclodiscus gabonensis (Okan/Denya), Shorea spp. (Bankirai), Dicorynia guia...

Long-term Performance of Treated Timbers in a Sub-tropical Marine Exposure
2023 - IRG/WP 23-11015
The long-term performance of preservative-treated and modified wood in marine exposures was assessed in Brisbane, Queensland, Australia. This report describes the final destructive assessment of the surviving Australian panels after 11 years of exposure. This site presents the potential for attack by shipworms (likely Bankia spp.), pholads (Martesia striata), Limnoria and Sphaeroma terebrans. Mos...

Assessing changes in hardness of furfurylated wood on a nano-scale to mimic levels experienced by the marine wood-boring crustacean, Limnoria
2023 - IRG/WP 23-11016
Wood-boring crustaceans and bivalves can cause severe damage to wooden structures in the marine environment, warranting the need for novel protection systems, such as chemical modifications. Furfurylation increases mechanical properties and resistance of timber species that would usually be susceptible to biodegradation by these borers, such as pine. In rapid laboratory and field testing, furfuryl...
