Life cycle approached environmental information to promote treated timber
2005 - IRG/WP 05-50224-13
This paper exemplifies the possibilities to compare products and product systems with help of life cycle assessment (LCA) as a tool for environmental assessment. IVL Swedish Environmental Research Institute has developed a concept for evaluation of environmental impacts based on normalisation, based on so called environmental quality objectives (EQO). This concept makes it possible to compare a pr...

Life Cycle Assessment of treated timber: methodological aspects and first results
2009 - IRG/WP 09-50264
Environmental information on products is more and more required as a key to the market, and the building sector in Europe is certainly advanced in that direction. In France, Environmental Product Declarations are becoming very common for construction products. Therefore, the CTB P+ and CTB B+ certification comity as commissioned FCBA to perform the Life Cycle Analysis of treated timber in order to...

Guideline for Environmental Product Declaration for Thermally Modified Timber
2012 - IRG/WP 12-50287
Environmental Product Declarations (EPD) intend to enable the comparison of the environmental attributes of products that meet equivalent functional requirements. This guideline describes the proceedings of EPD for thermally modified timber (TMT). The main objective is the general survey on requirements on EPD which are based on European and international standards.Up to now only a few EPDs for na...

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...

Danish wood preservatives approval system with special focus on assessment of the environmental risks associated with industrial wood preservatives
2001 - IRG/WP 01-50166-01
The following is a description of the procedure used by the Danish Environmental Protection Agency to assess the environmental risks associated with preservatives used in the pressure impregnation of wood. The risk assessment covers issues considered to be of significance for the environment and which are adequately documented so as to allow an assessment. Such issues are persistence and mobility ...

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 ...

Environmental status of wood preservation in the UK
1994 - IRG/WP 94-50018
The environmental status of wood preservatives and treated wood in the UK is summarised. The current legislatory position with respect to approvals, supply, use and waste disposal is considered. The bibliography at the end of this paper contains details of all publications referred to together with other relevant information although this cannot be exhaustive....

Loss of preservatives from treated wood during service
1992 - IRG/WP 92-3734
During the 23rd IRG conference in Harrogate the matter of preservative losses from treated wood during service was raised. We were asked to collect information in this field and ask now for help from you. Many tests have been carried out at a laboratory scale to study fixation and leaching from wood treated with different preservatives. Very little, however, is reported on losses of preservatives ...

Environmental issues: Messages for the wood preservation industry
1985 - IRG/WP 3353
A review of the origins and structure of environmental legislation throughout those territories of the world where wood preservation is a major industry is given. The implications of media, industry and legislation interaction is discussed and suggestions made as to the key issues the wood preservation industry should concentrate its attentions on in the immediate future....

Rates of emission from CCA-treated wood in the marine environment: measurement, modelling and requirements for further research
2001 - IRG/WP 01-50166-12
Accurate estimates of rates of emission of leachate from preservative treated wood are crucial for realistic predictions of the environmental impact of its use in maritime construction. Estimates are available for some commonly used preservatives, but these vary widely. Though variable, these measurements suggest that emission generally decreases exponentially with time. Part of the variation is d...

Quantitative determination of Chromium: A comparison of three instruments
1995 - IRG/WP 95-50053
A comparison is made between three instruments for measuring levels of chromium in the leachate of copper-chrome-arsenic (CCA) treated timber. These include an atomic absorption spectrophotometer, an inductively coupled plasma spectrometer and the RQflexâ. The RQflexâ is a new hand-held instrument which measures chromium by dipping a ReflectoquantÒ strip into the leachate and inserting the stri...

Environmental impact of CCA poles in service
1997 - IRG/WP 97-50087
Soil samples from different depths and distances from CCA treated utility poles in Canada were analyzed for copper, chromium and arsenic content for a number of soil types, two wood species red pine (Pinus resinosa) and jack pine (P. banksiana) and different pole ages in service. A limited number of poles were equipped with water traps to collect rain water that dripped down the poles and where su...

A review of environmental emissions from building and construction materials in comparison with preserved wood
2005 - IRG/WP 05-50224-11
A review of the public domain literature concerning emissions to the environment from materials which are used in the construction of buildings (e.g. Concrete, Asphalt, Galvanised Steel), in comparison with preserved wood, and a review of the approaches taken by the construction sector in assessing the risk from environmental emissions, in comparison with the approaches taken by the wood preservat...

Restrictions or environmental taxes as regulatory means - How will they influence the use of pressure treated wood?
1998 - IRG/WP 98-50101-28
In all the Nordic countries except Norway, we have environmental restrictions on the use of pressure treated wood. In Norway we expect environmental taxes on a large number of various products in 1998/99 - probably also pressure treated wood with one or more of the heavy metals copper, chromium and arsenic. The paper will discuss how this can influence the use of pressure treated wood and cause a...

Fully impregnated poles for a minimum environmental impact: Eucalyptus poles
2005 - IRG/WP 05-50224-24
The classical processes for preservation of wooden poles (vacuum-pressure and Boucherie processes) allow the impregnation of the sapwood only. The new radial-axial injection process has been applied to Eucalyptus poles, and has led to impregnation of both sapwood and heartwood. Further more; preserving product is injected both through the groundline area and through the bott end. This allows the...

Wood preservatives ecotoxicology on Gammarus pulex (L.) - toward an environmental monitoring method and a getting rid of pollution process
2005 - IRG/WP 05-50224-9
Wood preservatives can have a strong impact on freshwater invertebrates when used close to aquatic ecosystems. It has been reported in Jura that different arthropod taxa, specially crustaceans, have disappeared along several kilometers downstream from factories using insecticides and fungicides as wood preservatives. The crustacean Gammarus pulex (L.) is a relevant bioindicator to characterize th...

Framework document for an international code of good practices for wood preservation and wood protection (anti-sapstain) facilities
1992 - IRG/WP 92-3683
At the Kyoto meeting, the Health & Safety committee agreed to form a task force to prepare a global plan for writing a code of good practices (Code) for wood protection and preservation facilities (Doc. No. IRG/WP/3681). The Canadian document had been presented to the IRG group earlier (Doc. No. IRG/WP/3447) and similar documents were solicited from other countries for preparing a framework do...
