Evaluation of 'Deep Penetration Treatment' for wood preservation
2025 - IRG/WP 25-20746
‘Deep Penetration Treatment’ (DPT) is a recently developed wood preservation technique in Japan designed to meet the preservation standards required for residential foundations. This method involves spraying a specially formulated solvent-borne wood preservative onto properly incised dried lumber. Despite being a non-pressure treatment, DPT achieves penetration levels comparable to conventiona...

Influence of incising methods and wood moisture content on ‘deep penetration treatment’ in Japanese cedar and larch
2025 - IRG/WP 25-20749
To expand applicability of ‘deep penetration treatment’, a solvent-borne and non-pressure treatment that is commonly coupled with roller-type incising using a flat blade, we investigated drill and laser machining as alternative incising methods and examined the influence of wood moisture content on the preservative penetration. Various incising methods were applied to heartwood of Japanese ced...

Effect of biodiesel-containing solvents on the performance of Copper Naphthenate and Pentachlorophenol: 118-month assessment and depletion analysis
2025 - IRG/WP 25-41022
Solvent systems are incredibly important in determining the performance of oilborne wood preservative systems and they can cause early failures in commodities treated with an otherwise effective preservative system. It is important to assess new solvent performance with oilborne preservative systems to ensure these systems continue to function with the changes. One solvent/preservative combination...

Durability evaluation of outdoor-exposed CLT treated with various wood presevatives using CT scans
2025 - IRG/WP 25-41035
Methods for wood preservation treatment of large materials such as Cross Laminated Timber (CLT) are limited. It is unclear which wood preservation treatment methods can effectively protect CLT from rot risk. In this study, accelerated rot tests (fungus cellar test) of CLT treated with the solvent-borne wood preservative by non-pressure treatment, named ‘deep penetration treatment’, were conduc...

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...

Recycling wood treated with copper-based preservatives to produce hard carbon materials for energy storage applications
2025 - IRG/WP 25-50401
In this study, we explored the possibility of recycling wood treated with copper-based preservatives to produce hard carbon materials for use in energy storage devices. We pyrolsed both untreated and copper-treated wood into hard carbon, conducted microstructural and physicochemical characterisation, prepared electrode materials, and evaluated their electrochemical performance in sodium-ion batter...

Evaluation of Fungicide Transfer to Fruit Stored in Bins Constructed from Anti-Sapstain Treated Radiata Pine
2025 - IRG/WP 25-50417
This study investigates the potential transfer of fungicides to apples stored in bins made from wood treated with the anti-sapstain fungicides Antiblu® CC, containing carbendazim and chlorothalonil, and Antiblu® 375, containing oxine copper as an active ingredient. The analysis examines residues of chlorothalonil, carbendazim, and copper in apples exposed in mini-bins made from anti-sapstain tre...
