Impregnation of railway sleepers - Pressure gradient and transversal penetration
2016 - IRG/WP 16-40731
Based on the possible ban of creosote in the future, the need for oil based alternative products has gained in importance. Due to possible differences in impregnation properties compared to creosote the need for re-implementing former technology is given, to determine if momentarily used impregnation processes have to be modified. The here reported tests measure the pressure gradient during the im...

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...

Guidance on the European Biocidal Products Regulation Concerning Efficacy of Wood Preservatives
2017 - IRG/WP 17-20627
In Europe wood preservatives belong to Product Type 8 (PT8) of the Biocidal Products Regulation (BPR, EU n. 528/2012), which regulates the authorisation of biocidal active substances and products in the European market.
The applicant, who aims to obtain authorization to place a product onto the European market, needs to submit data to substantiate the label claims for the intended uses. Label cla...

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...

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...
