Potential for migration of boron from fused boron rods used as internal remedial treatments of utility poles
2014 - IRG/WP 14-50301
The distribution of boron in Douglas-fir utility poles and in the surrounding soil was assessed over a 54 month period following application of fused boron rods. Boron levels in the wood never reached the levels that might be predicted if diffusion were to produce a uniform chemical distribution, nor did levels in the soil suggest that boron was becoming more concentrated. The results suggest th...

Influence of Exposure Direction on Leaching of a Biocide from Painted Wood Surfaces
2014 - IRG/WP 14-50303
The objective of this project was to investigate the influence different exposure directions – North, East, South and West on the cumulative quantity of a biocide leached from painted wood surfaces due to rainfall and the consequences for the risk assessment. The study included a solvent-borne primer without biocides and a topcoat protected with a biocidal active substance. Both products were a...

Environmental Fate of Micronized Copper
2015 - IRG/WP 15-50310
The environmental fate of wood preservatives is an important aspect to estimate the health and environmental impact. Although biocides from treated wood may be released into the soil, water or air, the latter pathway is frequently neglected in favour of leaching studies. Nonetheless, wood dust is well known to cause a variety of adverse health effects, in particular diseases to the respiratory tra...

The Environmental Impact of Timber Products Compared to other Building Materials - A Survey of Published Environmental Product Declarations
2016 - IRG/WP 16-50314
One of the positive aspects of using wood in construction is the environmental benefits that this can potentially bring. However, manufacturers of all construction products and materials make claims about the ‘environmental friendliness’ of their products, making it exceedingly difficult for the end user to make informed choices about the advisability of using one product over another. This st...

Contamination of recycled wood from selected recycling companies in Europe
2016 - IRG/WP 16-50322
Recycled wood is becoming more and more important material source for production of new materials and chemicals. For good quality of end products predominately clean recycled wood should be used. In present research, we have focus on concentrations of non-wooden materials in recycled wood and presence of inorganic pollutants: chlorine (Cl), chromium (Cr), copper (Cu), zinc (Zn), lead (Pb), iron (F...

Wood Protection and Environmental Performance of Products - Impacts COST Action FP1407 Aims to Bring
2016 - IRG/WP 16-50323
Though many aspects of wood modification (chemical, thermal, impregnation) treatments are known, the fundamental influence of the process on product performance, the environment, and end of life scenarios remain unknown. To contribute to the low-carbon economy and sustainable development, it is essential to integrate interactive assessment of process parameters, developed product properties, and e...

Response of Terminalia mantaly H. Perrier wood to beetles tunneling in Southern Nigeria
2018 - IRG/WP 18-10918
Terminalia mantaly (TM), is extremely susceptible to beetles attack, as evidenced by the many scars and/or tunnels on nearly all the trees in the Southern Nigeria. However, information on the responses of wood to insects tunnelling is poorly known for tropical species. To examine the response of TM stem wood to beetles tunnelling in the University of Port Harcourt, we scheduled field observational...

Influence of different triazoles as co-biocides in wood preservatives on efficacy and the environmental impact
2018 - IRG/WP 18-50333
In this study we investigated the efficacy and impact on the environment of different co-biocide triazoles in wood preservatives. Four different formulations (all containing 9.5% Copper) contained individual and combinations of cyproconazole, tebuconazole, propiconazole as co-biocides. Four formulations were tested according to EN 113 and EN 84 (ageing) to determine the brv for each formulation. T...

Long service life or cascading? The environmental impact of maintenance of wood-based materials for building envelope and their recycling options
2018 - IRG/WP 18-50336
A major restraint in choosing bio-based materials (i.e. wood-based) for external use, is the lack of confidence that architects, designers and customers have toward these materials. In particular, the limit state of bio-based materials, which defines the frequency of maintenance operations, might be reached earlier for wood than for other materials (i.e. concrete). On the other hand, resource and ...

Declaring life cycle inventory of toxicity related emissions in environmental product declarations of preservative treated wood products
2018 - IRG/WP 18-50339
Life cycle assessment (LCA) including impacts on toxicity for preservative treated wood has been shown to have large uncertainties. With the growing demand for verified LCA in environmental product declarations (EPD), the need for reliable data is crucial for realistic assessment of wood products. Uncertainty is caused by several issues such as service life prediction, leaching rates and calculati...

Environmental protection and long term in-service sustainability of preserved wooden poles is secured by non-toxic barrier protection system – History and case studies in South Africa
2018 - IRG/WP 18-50340
Non-toxic flexible sheeting systems have been developed to encapsulate the ground contact regions of preserved wooden poles and prevent their premature failure in South Africa since 1992 but the technology also has a long history of resistance by individuals with vested interests in the built-in redundancies of such poles. The concept has, however, been simultaneously validated by many independent...

DuraSoft Project: a multidisciplinary approach for softwood protection
2021 - IRG/WP 21-50367
Over the course of millennia, fishing and agro-pastoral activities have produced unique housing types in the Italian lagoons and in the Slovenian highlands where the use of wood is predominant. They are associated with wooden service infrastructures such as piers, moorings, piling and fences. However, the existence of these structures and the associated cultural heritage are subject to constant ...
