Overview of the treated wood quality control program in the United States with the recent challenges and advances
2017 - IRG/WP 17-20616
In the past two decades, there have been significant and rapid changes in wood protection technologies for residential applications which have moved away from long established heavy duty metal oxide based products such as chromated copper arsenate (CCA). The successor generation of wood protection systems usually contain copper as the primary biocide, in combination with carbon-based co-biocides s...

Possibility of using lichen (Usnea filipendula) and mistletoe (Viscum album L.) extracts as potential natural wood preservative
2017 - IRG/WP 17-30712
Increasing environmental pressures on toxic chemical wood preservatives lead to the development of natural and environmentally friendly wood preservatives. In this study, using possibilities of lichen (Usnea filipendula) and leaves of mistletoe (Viscum album L.) as potential natural wood preservative were researched. Treatment solutions have been prepared with two different solvents, water and met...

The Effects of Pre-Microwave Treatment on Retention Levels And Some Mechanical Properties of Spruce Wood Treated with CCA
2017 - IRG/WP 17-40800
Microwave (MW) treatment of wood has been evaluated in recent years for different purposes by several scientists. Microwave conditioning improves permeability, reduces density and heat conductivity and changes dimensional stability. Furthermore, it could even improve the permeability of refractory wood species such as spruce and Douglas fir. In this study, MW pre-treatment was applied to spruce wo...

The anatomical determination of wood samples found in the “Fürstengräber” from Lübsow (Poland)
2018 - IRG/WP 18-10930
The paper presents the results of anatomical research identifying three wooden fragments from the “Princes Graves” (“Fürstengräber”) in Lübsow, Poland. The research demonstrates that the wooden fragments are typical of wood harvested from European forests.
The physicals conclusions are important for the research of Jan Schuster, from the University of Lodz, Institute of Archeology, Pol...

Treatability of South African-grown Eucalyptus grandis with water-borne copper azole and disodium octaborate tetrahydrate wood preservatives
2021 - IRG/WP 21-40920
This study investigated the treatability of the sapwood and heartwood of sawn Eucalyptus grandis with copper-azole (CuAz) and disodium octaborate tetrahydrate (DOT) water-borne preservatives towards improving its durability for enhanced use in structural solid wood applications. The results obtained showed that, at a moisture content of 12 ± 1%, sawn E. grandis sapwood can be impregnated to a mea...

The influence of climate changes on Central European forests with an emphasis on Slovenia
2022 - IRG/WP 22-50368
When forests are managed sustainably, they play an essential role in protecting climate and biodiversity. They protect soils and water resources, provide livelihoods, and contribute to the well-being of rural and urban communities. European forests are multifunctional and provide a range of ecosystem services. These include the production of renewable materials that can replace materials with a la...

Preservative properties of boron-treated paulownia wood
2024 - IRG/WP 24-20729
This research was performed to investigate the preservative retention properties of paulownia wood treated using boric acid/borax at mass ratio of 1:1.8. Different portion of paulownia wood (top, middle, bottom) were used as a sample throughout of this study. In the treatment process, the paulownia wood was dipped in the 1% boric acid/borax solution for 1, 24, 72, 120 and 240 hours to achieve requ...

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...
