Issues facing the industry include: Re-evaluation of the conventional wood preservative chemicals - inorganic arsenicals, creosote and pentachlorophenol targeted for July 2001. Delayed registration of new actives as a result of re-evaluation activity an...

Options for accelerated boron treatment: A practical review of alternatives
1985 - IRG/WP 3329
Boron wood preservatives are almost exclusively applied by momentary immersion and block diffusion storage. Alternative techniques are described which can be used to accelerate boron treatment. Diffusion coefficients have been derived to define the acceleration of diffusion with increasing temperature. Schedules are described for pressure impregnation of green timber, involving steam conditioning,...

Current and future options for managing used preservative-treated wood
1995 - IRG/WP 95-50042
The amount of preservative-treated wood available for disposal will continue to increase exponentially in the next several decades as landfill availability declines. At the same time, recent legal ruling on competitiveness among utilities and disposal of ash has clouded the economic outlook for combustion of treated wood for energy recovery. This report identifies current and future options for ma...

Options for termite management using the insect pathogenic fungus Metarhizium anisopliae
1996 - IRG/WP 96-10142
The insect pathogenic hyphomycete fungus Metarhizium anisopliae (Metschnikoff) Sorokin is promising as a biological insecticide for many species of subterranean termites. In Australia, a survey of termite mounds and feeding sites using a selective medium showed that this fungus is widespread but rarely causes mortality of termites under natural conditions. One isolate, codenamed FI610, has been se...

Non agricultural biocide directive. Practical proposals of implementation in the case where biocides are wood preservatives
1995 - IRG/WP 95-50040-24
This project of non-agricultural biocide directive has currently an extremely wide scope of pre-marketing authorization of substances and preparations used in numerous applications, other than agricultural. Elaborated on the 86/414/EEC model of the phytopharmaceutical product directive, the "NAB" draft directive aims to cover situations as different as plant or wood protection: in the case of plan...

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 ...

End-of-life options for engineered wood products / Treated timber in a circular economy
2023 - IRG/WP 23-50383
Australians are excellent consumers of products. These products ultimately end up as waste materials and need to go somewhere. Australia produces around 28 million tons of waste per year with around 50% currently ending up in landfill, including a significant amount of timber, engineered wood products (EWP’s), and preservative treated wood (PTW). Limited landfill capacity, increasing costs, and ...
