Building solid foundations to support market growth of preserved wood in the UK – treatment quality, product approval and the largest national field trial of preservative treated wood in 50 years
2015 - IRG/WP 15-30662
The Wood Protection Association (WPA) has just commissioned Britain’s largest ever durability trial of home grown timber, having contracted Building Research Establishment (BRE) to conduct a long term controlled field trial of sawn and pressure treated British Softwood posts at two sites with differing soil conditions. This large scale Field Trial is the last of an innovative and substantial thr...

The Environmental Impact of Timber Products Compared to other Building Materials - A Survey of Published Environmental Product Declarations
2016 - IRG/WP 16-50314
One of the positive aspects of using wood in construction is the environmental benefits that this can potentially bring. However, manufacturers of all construction products and materials make claims about the ‘environmental friendliness’ of their products, making it exceedingly difficult for the end user to make informed choices about the advisability of using one product over another. This st...

Penetration behaviour of different hydrophobic carrier substances for oily wood preservatives in Beech and Scots pine sapwood
2017 - IRG/WP 17-40804
The use of creosote as a wood preservative has a long history. Current areas of application are railway sleepers, transmission poles, timber bridges and marine applications. If the approval for creosote will not be prolonged, alternative wood preservatives will be needed. As the penetration behaviour after pressure impregnation of different alternative oily products in this fields of application i...

Declaring life cycle inventory of toxicity related emissions in environmental product declarations of preservative treated wood products
2018 - IRG/WP 18-50339
Life cycle assessment (LCA) including impacts on toxicity for preservative treated wood has been shown to have large uncertainties. With the growing demand for verified LCA in environmental product declarations (EPD), the need for reliable data is crucial for realistic assessment of wood products. Uncertainty is caused by several issues such as service life prediction, leaching rates and calculati...

COPPER NAPHTHENATE: A Product for All Seasons: Protecting the Americas’ Infrastructure for Over 100 Years and Potential for Expanded Usage in Europe
2019 - IRG/WP 19-30738
This paper is a brief review of the history and use of the wood preservative Copper Naphthenate, with a focus on use patterns within the USA and opportunities for expansion in Europe and Canada. This paper reviews how copper naphthenate has performed to preserve and protect cellulosic and wooden items essential to critical infrastructure, and why it is the ideal choice for use in the replacement o...

Chemical composition and performances of slow pyrolysis by-product from sugarcane bagasse for wood protection
2020 - IRG/WP 20-30752
Pyrolysis distillate or bio-oil, a by-product of biomasses’ slow pyrolysis in the char-making process, has been traditionally used as bio-pesticides by Asian farmers. Due to its large composition of bio-active chemicals, bio-oil obtained from various biomass has become of interest in many applications, including wood protectants. This study aims to characterize the chemical composition of bio-oi...

Impregnation of railway sleepers - Investigation of a system-sleeper as an alternative for creosote treated sleepers
2020 - IRG/WP 20-40896
For nearly 200 years wooden railway sleepers are impregnated with creosote. After initially using vacuum pressure processes for impregnation, empty-cell processes have been developed quickly and are used until today. Because of political developments, creosote will probably be banned on the European market in the near future. The Fürstenberg-System-Sleeper, which combines for Europe innovative as...

Efficacy of a wide-spectrum plant bio-based anti-termite product - Laboratory trials
2023 - IRG/WP 23-11024
Compared to the number of timbers available, the list of wood species resistant to termites is rather limited and largely composed of tropical timbers. In addition, due to climate change and environmental degradation, together with global trade, a significant global expansion of termites is predicted along with the economic losses due to their activities. Therefore, there is a demand to find produ...
