The spread of technology in a simple wooden pile construction method to prevent shallow landslides
2025 - IRG/WP 25-20733
This study introduces the development and practical application of an innovative slope stabilization technique called the Wood Pile Root System Method (WPRSM), aimed at preventing shallow landslides, which have increased due to the rising occurrence of extreme weather events caused by climate change. This method effectively reinforces slopes using thinned timber, providing a sustainable and cost-e...

Improvement and practical application of dry-type pressure treatment method
2025 - IRG/WP 25-20734
In years, the need for environmental consideration has been reaffirmed worldwide, and in Japan too, there is a demand for the expansion of the uses of wood in order to achieve a decarbonised society. So, there is also a need to develop and improve wood preservation treatment methods that overcome the weaknesses of wood and enable it to be used in a wide range of applications. The authors have impr...

Enhancing the Fire Resistance of Spruce Wood through Treatment and Additive Application: Small Flame Test Method
2025 - IRG/WP 25-20737
Spruce panels treated by spraying with Burnblock® spray, were tested using “Small flame test method” according to EN ISO 11925-2:2011. The fire retardant product from Burnblock ApS is reported by the Danish company to be bioderived and non-toxic. The results for the untreated planed spruce showed moderate flammability whereas the Burn Block treated panels exhibited exceptional fire resistance...

AI Models for Accelerating Wood Protection Testing: Development of Predictive Tools Based on Long-Term Field Test Data
2025 - IRG/WP 25-41023
In this study, we present the development of DecAI, an artificial intelligence (AI) model designed to optimise and accelerate performance evaluations of wood protection products in the European EN 330:2014 "Field test: L-joint method." The Danish Technological Institute (DTI) compiled a dataset of over 100,000 data points from approx.10,000 L-joint samples collected over +15 years at field sites i...

Validation of a measurement method for cyproconazole retention in pressure-treated wood through an interlaboratory study
2025 - IRG/WP 25-41037
The Japanese Agricultural standard (JAS) defines national regulations for preserved wood and wooden materials, in Japan. Traditionally the JAS focused on quality of product, however, the revision of the JAS Act in 2017 enabled standardisation of test or measurement method for the quality evaluation. The Japan Wood Protection Association (JWPA) has been working toward standardisation of methods for...

Non-destructive methods for field assessment of wood biodeterioration in hardwood trailer decks exposed to tropical environments
2025 - IRG/WP 25-41039
Apitong (Dipterocarpus spp.), an increasingly rare tropical hardwood from the rainforest in Southeast Asia, has long been used as decking materials for open-bed trailers and trucks across North America. As the natural population of Apitong trees steadily declines, there is an urgent need to find sustainable, domestically sourced alternatives for trailer decking. A recent project evaluated the perf...

Durability Enhancement of US Hardwoods for Use in Open Trailer Decks
2025 - IRG/WP 25-41048
Apitong, a tropical hardwood derived from endangered species within Dipterocarpus genus, has long been used as a decking material for open flat-bed and lowboy trailers in the U.S. However, as more Dipterocarpus species are classified as endangered and critically endangered by International Union for Conservation of Nature (IUCN) due to the declining population of Apitong trees, there is a growing ...

Physical and chemical characterization of post-consumer wood chips for recycling
2025 - IRG/WP 25-50414
Post-consumer wood (PCW) is a valuable resource that can partially substitute virgin wood in material applications. This communication paper presents key findings from a study that analysed PCW collected from three recycling facilities in southeastern Norway over eight months. A total of 20 mixed and 4 pre-sorted PCW samples were evaluated regarding their material composition, particle geometry, a...
