Bio-durability and weathering performances of cardanol-treated wood
2024 - IRG/WP 24-30809
Cardanol is an excellent insecticide, fungicide, and termiticide derived from thermally treated cashew nutshell liquid (CNSL) and has been extensively explored in the chemical industry and for medicinal uses. However, its potential for wood protection remains unexplored. This study aims to understand the bio-durability and weathering properties of cardanol-treated wood. The southern pine and yello...

Field performance of preserved shakes and shingles
2024 - IRG/WP 24-41000
Wood shakes and shingles are used in applications where they are at risk of decay, either in sidewall (UC3.1) or roofing (UC3.2) applications. Material durability may come from using the heartwood of naturally durable species, using preservative treatments, or both. Through a series of long-term field tests, this paper explores the performance of naturally durable and preserved shakes and shingles...

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...

Copper migration from preservative-treated Douglas-fir decking: models vs laboratory leaching data
2024 - IRG/WP 24-50390
The ability of a model to predict copper migration from Douglas-fir treated with organic metallic substances into a freshwater slough was evaluated against data generated through simulated overhead leaching. The model predicted very high loadings of ammoniacal copper zinc arsenate, alkaline copper quaternary or copper azole that had the potential to impact water quality while data from the exper...

Quantitative assessment of wood preservative emissions to waterways
2024 - IRG/WP 24-50393
The Organisation for Economic Co-operation and Development (OECD) Emission Scenario Document (ESD) for Wood Preservatives provides methods to quantify the release of active substances from treated wood for various scenarios including sheet pilings in a flowing waterway (OECD 2013). The ESD is used for environmental risk assessment of wood preservatives according to the Biocidal Products Regulation...
