Effect of soil parameters on biocide depletion: laboratory and field studies of water- and emulsion-borne preservatives
2000 - IRG/WP 00-30234
Two field test sites with different soils were selected. Soil analysis showed that the soil at the two sites had considerable texture, base saturation, acidity, and cation exchange capacity differences. Five sets of field stakes were treated as follows: three with water-borne CCA to about 0.4 pcf (6.4 kgm-3) retention, one with 0.75% DDAC, and one with 0.75% DDAC:0.25% chlorothalonil. The last two...

Life-cycle assessement of treated wood: A view from the roa
1996 - IRG/WP 96-50078
Life Cycle Assessement (LCA) is being used increasingly as a tool to structure information on the environmental characteristics of material and processes. This paper is based on the experience gained from our LCA studies on treated wood products over the last 4 years. The comprehensive and logical examination af the information available on treated timber provided by LCA has allowed identification...

Removal of CCA from Spent CCA-Treated Wood
2002 - IRG/WP 02-50192
A novel method for the removal of CCA components from spent CCA-treated wood has been developed. The CCA-treated wood was first converted into liquid in the presence of polyethylene glycol and glycerin at mild temperatures (120 – 150 0C) by using sulfuric acid as catalyst. The resulting viscous liquefied wood was then resolved in acetone/water solvent. The hazardous components (i.e., Cr, As, and...

An evaluation of the potential of ion mobility spectrometry for detection of organic wood preservative components in solutions and treated wood
1994 - IRG/WP 94-20038
For the disposal of wood waste under ecological sound conditions information about its hazardous potential is required. Until now, no highly sensitive rapid analytical methods are available for the detection of wood preservatives under industrial process conditions. Preliminary experiments showed that Ion Mobility Spectrometry (IMS) could be a promising method for rapid detection of organic preser...

Bamboo preservation in Vietnam
2009 - IRG/WP 09-40457
This paper presents the current state of bamboo preservation in Vietnam. The report focuses on the importance of bamboo preservation in relation to the bamboo resource and utilization, the major methods for preservation (such as non chemical und chemical methods), and emphasises the today’s pressing problems of research, standards as well as information for the bamboo preservation industry in Vi...

The resistance of wood coated with different solvent-borne paints against colonisation by decay fungi
2009 - IRG/WP 09-40468
This paper examines different solvent-borne paints characteristics and their decay resistance when applied on pine wood surface. It was determined by the standard ENV 839 procedure. The part of samples were subjected to accelerated ageing according to the EN 84 standard. The discussed commercial paint systems were typical stains or penetrating oil-based products, with or without biocides....

Bioprocessing preservative-treated waste wood
2000 - IRG/WP 00-50145
Disposal of preservative-treated waste wood is a growing problem worldwide. Bioprocessing the treated wood offers one approach to waste management under certain conditions. One goal is to use wood decay fungi to reduce the volume of waste with an easily managed system in a cost-effective manner. Wood decay fungi were obtained from culture collections in the Mycology Center and Biodeterioration res...

Timber infesting species of Col. Lyctidae and Bostrichidae imported into Germany since ca. 1985
2000 - IRG/WP 00-10385
This contribution to the knowledge of passively and unintendedly dispersed species of Col. Bostrichoidea has been derived from the author's private investigation in cooperation with German quarantaine institutions from 1996 to 1999. It is a brief summing-up of the importations of timber infesting "Powder-post Beetles" (Col. Lyctidae) and "Borer Beetles" (Bostrichoidae) into a European ind...

Environmental risk assessment of treated timber in service: The Environment Focus Group approach
2000 - IRG/WP 00-50162
In the context of the Biocidal Products Directive (98/8/EC), and of the OECD work on wood preservatives, the Environment Focus Group (EFG), comprising 8 institutes and the European Wood Preservative Manufacturers Group, has been working on the environmental risk assessment of treated timber in service. A literature review of emissions from treated timber has revealed that very little existing data...

The Effect of Soil on the pH of Untreated Southern Pine in Ground Contact
2010 - IRG/WP 10-10742
Untreated southern yellow pine samples were subjected to three soils that had been amended to provide acidic, neutral and alkaline conditions. Wood pH was measured prior to, and then one, two, four and eight weeks after being placed in the soil to determine the effect of soil pH on wood pH....

Accreditation: mutual benefits for research and industry
2010 - IRG/WP 10-20452
The wood preservation laboratory of the CIRAD had its first ISO 17025 accreditation from the COFRAC in 2006 for 5 standardized test procedures. The so called “first cycle” of its accreditation will be mid-2010. This laboratory is now accredited for 8 tests and is planning to increase the field of its quality management and accreditation. This poster describes how research projects, pre-normati...

Moisture uptake and volumetric swelling as probable factors also affecting leaching in CCA-treated wood. A preliminary study of treated Eucalyptus saligna sapwood
2003 - IRG/WP 03-30318
IRG/WP 03-30318
A number of factors affecting leaching of CCA from treated wood have been variously investigated and discussed. However, the possible effects of moisture movement in treated timbers on leaching have not received attention yet. The present study examines and compares moisture uptake and volumetric swelling in CCA-treated and untreated sapwood of Eucalyptus saligna, and tries to establish a correl...

The influence of wood moisture content on the fungitoxicity of methylisothiocyanate in Douglas fir heartwood
1987 - IRG/WP 3430
The fumigant methylisothiocyanate (MIT) effectively controls decay fungi in large wood structures, but the influence of environmental factors on its performance are not well understood. Experiments found wood moisture content to greatly influence the fungitoxicity and sorption of MIT in Douglas fir heartwood. At constant, low MIT vapor concentrations (less than 1 µg/cc air), wood at 10% MC bound ...

The effectiveness of deltamethrin against subterranean termites (final report)
1993 - IRG/WP 93-30011
Two series of block tests of Pinus sp were treated by dipping them for 1 (one) minute in a solution with 0.015 (w/w) and 0.05 (w/w) of deltamethrin, respectively. In both cases, an average retention of 47 kg/m³ (0.32 l/m) was reached. One part of the block tests remained under laboratory conditions during 9 months, and the other was stored during equal period of time in a theater basement submitt...
