Evaluatiang the potency of cinnamaldehyde as a natural wood preservatives
2007 - IRG/WP 07-30444
Since cinnamaldehyde, the major constituent of leaf essential oil from Cinnamomum osmophloeum, has significant antifungal and antitermitic activities, it is worthy of understanding whether cinnamaldehyde has potential to be used as a natural preservative for improving the durability of wood. In this study, the fungi and termite resistance of cinnamaldehyde-treated wood (CTW) were evaluated accordi...

Tar-oil uptake vs time in immersion treatment of short pine posts: A simple technique applicable to rural communities of Papua New Guinea
2012 - IRG/WP 12-40608
Pinus caribaea and Araucaria cunninghamii logs ca. 100 mm in diameter were shortened to lengths 25-30 cm, conditioned to at/below fibre saturation point (FSP) for immersion/dip treatment using a hot- and- cold bath open- tank process. Before oven-drying and subsequent treatment, individual test specimens were numbered, their green weights and volumes, and dry weights recorded for basic density, vo...

Bio-Based but Toxic? The Neglected Ecotoxicity of Leachates from Wood Preservatives—A mini-review
2025 - IRG/WP 25-50403
Bio-based Wood preservatives, derived from renewable biomass, are emerging as promising alternatives to traditional synthetic wood preservatives. Research groups all around the world are studying the development of bio-based – environmentally friendly – wood preservatives and their fixation to wood finding natural compounds with very promising wood preserving potential. However, there is a ver...

The applicability of life cyle analysis and alternative methods in the wood preservation industry
1994 - IRG/WP 94-50023
In the Netherlands, several case studies have been performed using the life cycle analysis method (LCA). This type of research is aimed at an inventory and classification (sometimes including also evaluation) of the environmental impacts of a product, from the raw material to waste stage ("cradle to grave" approach). In a LCA each environmental impact is assessed in terms of, for example, mass of ...

The evaluation of permethrin for wood preservation
1977 - IRG/WP 3107
The toxicity of the synthetic pyrethroid permethrin (NRDC 143) to a range of wood destroying insects has been investigated. In tests using Hylotrupes bajulus, Anobium punctatum, Lyctus brunneus and Reticulitermes santonensis permethrin showed a similar order of toxicity to that of gamma-BHC. Although the toxicity of permethrin to adult Anobium punctatum was of the same order as that of gamma-BHC, ...

A proposal for an international wood preservation standard
1994 - IRG/WP 94-20031
Two factors are driving the need for an international wood preservation standard. First, the global need to use our natural resources more wisely and second, the movement towards free trade exemplified by the General Agreement on Tariffs and Trade. The International Research Group on Wood Preservation is the ideal organisation to undertake the task of developing such a standard. This paper is inte...
