Methods of treatment of wood preservatives. The selection of appropriate preservation process with particular reference to mixed tropical forest resources. A key address
1982 - IRG/WP 3177
All wood is biodegradable. Many timber species have, however, sufficient natural durability to permit their use, particularly in protected situations, without any special precautions. Many others, of course, are readily attacked by insects and where there is sufficient moisture and air, by wood-decaying fungi. It is these timber species which benefit most from treatment with wood preservatives. Ev...

Wood Preservation India; Current Scenario
2013 - IRG/WP 13-40630
This short note describes the present status of wood preservation research and its industrial application. Although good performing formulations have been developed by Indian research laboratories, industry has not tried to derive benefits from this development. Many unknown products are flooding the market for brush on applications with little benefit as the products have not been standardized....

Status of wood preservation in India
2005 - IRG/WP 05-30386
Wood, despite the advent of other modern materials, continues to play an important role in man’s day to day life. Usage of wood ranges from fuelwood to engineered wood products and demand for it is increasing which has resulted in depletion of forests and diminishing wood supplies. Future needs are required to be met from plantation timbers after adopting processing technologies for their life...

The need for realism in wood preservation research. A key address
1983 - IRG/WP 3254
The approval of a chemical for use as a timber preservative and the design of in service retention requirements represents an act linking fundamental research and commercial timber preservation. How difficult is it to translate figures generated through controlled experimentation into working specifications and how confident can we be in the methods used to provide such figures? The chairman of Wo...

A comment on problem orientated research for the preservation industry
1984 - IRG/WP 3303
Wood preservation is a technological discipline, based upon a number of fundamental sciences, including biology and chemistry. The International Research Group on Wood Preservation (IRG) is presently structured to support the preservation industry, since IRG working groups attempt to strike a balance between fundamental aspects and technological needs. Over the years there has been an increasing r...

Wood Preservation in Belgium
1981 - IRG/WP 3170
The report reviews wood preservation activities in Belgium and notes the number of authorized treatment depots has doubled during the past five years. It lists the timbers that are allowed to be used for joinery and constructional building purposes and the preservatives and treatments with which these timbers may be protected. In Belgium not only have the wood preservative product and its treatmen...

Wood preservation in Brazil
1978 - IRG/WP 3126
Wood preservation was stablished in Brazil by 1902 in order to provide treated sleepers for railways, since there was a shortage of durable hardwoods in area served by railways. The growing need of sleepers and poles together with the availability of Eucalyptus spp. contributed for the development of wood preservation. Many wood preservation plants started to be stablished in 1957, and in 1977 the...

Computerised data acquisition and barcode technology - Examples of its application and use in wood preservation research
1992 - IRG/WP 92-2404
Experimental samples in wood preservation research are usually individually labelled with either some form of durable marking pen or more commonly with a stamped metal or plastic tag. The label must remain intact and legible for the duration of the experiment which, in the case of a field trial, can be many years. Preservative performance data have traditionally been recorded manually on a data sh...

Wood preservation research in Tanzania: Priorities and challenges
1988 - IRG/WP 3462
Tanzania provides some of the highest rates of wood deterioration in service leading to alarming economic losses and yet no serious concern is shown in search for solutions to the problem. The paper attempts to point out some of the priority areas in the field of wood preservation research that demand urgent attention if timber is to be used judiciously in this country. An account is given of the ...

International co-operation in wood preservation research
1979 - IRG/WP 3145
If one searched the literature, one could find many examples of international co-operation in the field of research in wood preservation. For example, individual workers in different countries in Europe have got together and made replicate tests with both fungi and insects on various preservatives of common interest and their results have been published. Much co-operation has not had its results p...

Wood preservation in Croatia
2004 - IRG/WP 04-30360
Croatia, as all the other countries in transition, however also because of its specific and well-known reasons, is on a path to gradual drawing nearer to the European standards. Only the scientists working at the Faculty of Forestry in Zagreb are engaged in scientific work relating to wood preservation.
The construction and wood industry, which should enhance the chemical industry, also have subs...

Wood Protection in Croatia – Situation from the Acquisition of Independence till Today
2010 - IRG/WP 10-40501
In the last eighteen years in Croatian wood-working industry, respectively wood protection industry, many good changes happened. In such a short period of time Croatian industry changed their “product philosophy”. After the fatherland war and acquisition of independence the most logs and sawn wood products have been exported from Croatia. With such “kind of philosophy” Croatian wood-workin...

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...
