Evaluating the Effects of Post Dip-Treatment Laser Marking on Resistance to Feeding by Subterranean Termites
2016 - IRG/WP 16-10854
Dip-treatment of wood packing materials is often used instead of pressure treatment mainly because of issues relating to simplicity and cost. Packaging boxes fabricated for the United States Army are required to be dip-treated for at least one minute in an approved preservative solution prior to use. These boxes are expected to have a service life of up to 20 years in a wide variety of environment...

Natural resistance of Bambusa vulgaris to termite and powder-post beetle attack in laboratory and graveyard tests
2018 - IRG/WP 18-10925
Deterioration is the major setback to the utilisation of bamboo products. To enhance bamboo utilization, an understanding of the level of resistance to degradation is important. In this study, level at which Bambusa vulgaris will naturally resistant attack by subterranean termites and powder-post beetles were evaluated. B. vulgaris aged 2, 3 and 4 years were subjected to attack by subterranean ter...

Non-stochiometric oxidation and ROS generation promoted by guaiacol lignin structures and lignocelluose surfaces may be a component of brown rot fungal degradation mechanisms
2019 - IRG/WP 19-10937
Model guaiacol compounds representing lignin monomers, as well as DHP-lignin and wood flour of controlled particle size were used to assess iron reduction at the pH of the natural wood cell wall. All compounds functioned as electron donors for ferric iron, with the lignin monomers demonstrating capacity for non-stochiometric reduction of iron with multiple moles of ferric ion reduced per mole of l...

Post-layup protection of mass timber elements in above ground protected exposures: 2-year results
2022 - IRG/WP 22-30766
Mass timber has seen increased use as a building material for low and mid-rise construction in recent decades. The durability of mass timber elements has not been fully examined and the effects of wood destroying organisms on this these materials merits attention. The effectiveness of currently labeled soil termiticides and passively applied biocides at post-construction or as remedial agents need...

Bio-based thermal insulation panels – a way of cascading utilization of post-consumer wood
2024 - IRG/WP 24-50388
Cascading wood utilization is critical to fulfilling a circular economy frame in the wood industry. The work's aim was to apply wood dust from plywood production to the production of innovative bio-based thermal insulation panels. Trametes hirsute fungus was used as a composite binder, and then a composite structure and thermal insulation properties, water absorbability, and strength properties of...

Levels of chromated copper arsenate in aged radiata pine vineyard posts
2024 - IRG/WP 24-50389
At the Centre for Timber Durability and Design Life, Australia a cooperative project is underway with Forest and Wood Products Australia, supported by a consortium of timber producers, chemical suppliers and timber users to identify alternative pathways for treated timber and EWP’s. Under this initiative, we are focusing on establishing the current and forecasting future volumes of treated timbe...

mpact of Fence Post Footings on Wood Post Durability
2025 - IRG/WP 25-41025
Residential wood fence posts may be dug directly into the ground, secured to a metal spike that goes into the ground, or secured to a concrete footing with a metal boot. It was hypothesised that by keeping wood posts out of the ground both spikes and boot attachments would increase protection against decay and termites and extend the service life of the post. After 9-years of exposure in Kincardin...

Timber reuse and circularity: Insight from Norway's SirkTre and CircWOOD initiatives
2025 - IRG/WP 25-50409
Timber is central to the EU’s decarbonisation strategy, particularly in the building sector, which faces challenges related to climate adaptation, resource constraints, and rising costs. The four-year SirkTRE project aims to improve circularity in the timber industry by developing standards, promoting reuse, and expanding market opportunities. A key focus of SirkTRE is to increase the longevity ...

Leveraging Geospatial Mapping for Timber Circularity in Australia
2025 - IRG/WP 25-50410
Timber, renowned for its low embodied carbon and renewable characteristics, is a prime candidate for integration into the circular economy. However, challenges arise in the reuse, repurposing, and recycling of chemically treated materials. The National Centre for Timber Durability and Design Life (NCTDDL) at the University of the Sunshine Coast (UniSC) is leading a collaborative initiative with Fo...

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...
