Waste management of wood products in life cycle assessment
2000 - IRG/WP 00-50154
Within the framework of the European project LIFE SYS WOOD (contractnr. FAIR CT95-7026) TNO has performed a study on the waste management of wood demolition waste for inclusion in Life Cycle Assessment. In LIFE SYS WOOD one of the main aims was to develop a consistent LCA methodology for wood products. LCA case studies have been performed by partners on wood as raw material, glulam contructions, O...

Remedial treatment of joinery. Comparison of distribution of organic solvent preservative and ammonium bifluoride
1978 - IRG/WP 3115
It is some years since it was recognised in the United Kingdom that there was a problem of premature decay in untreated external joinery. Consequently, recommendations for preservative treatment were made by the Building Research Establishment, Princes Risborough Laboratory. In addition, the National House-Building Council has also included the preservative treatment of external joinery in its req...

The effect of creosote and Basilit on the boards of 4 wood species against destructive fungi in Northern Iran
1989 - IRG/WP 3555
The results of the experiments conducted on the boards of maple, hornbeam, alder and beech, show that under the humid and moderate climate condition of Northern Iran, after 30 months, the witness samples were about 10% destructed by fungi, especially by Schyzophyllum commune and Coriolus versicolor. The impregnated samples by Creosote Basilite using Rueping and Bethell methods, were quite intact. ...

Utilization of plasma treatments in the field of wood protection
2021 - IRG/WP 21-40912
Plasma treatments have been used for modification of surfaces of wood and wood-based materials for some decades and solutions were developed to apply it for wood protection. This contribution aims to present the background, introduce the available plasma technology, and to give an overview on the typical applications and benefits....

Laboratory evaluation of fipronil (a phenyl pyrazole) as a candidate termiticide in the protection of wood against the subterranean termite, Coptotermes acinaciformis (Froggatt) Rhinotermitidae
1997 - IRG/WP 97-10225
In this laboratory evaluation, radiata pine wood blocks (50 x 25 x 15 mm3) were impregnated with fipronil (a phenyl pyrazole) at various concentrations (0, 5, 10, 20, 40, 80, 100 and 200 ppm). Half the treated blocks underwent a leaching schedule for 5 days, while the remainder were unleached after treatment. Five replicates per treatment regime were presented to the test termite, Coptotermes acin...

Ten year field test with a copper-borate ground line treatment for poles
1993 - IRG/WP 93-30017
A wood preservative paste consisting of borax and copper naphthenate has been tested to determine its efficiency in protecting wood from decay fungi and insects. The paste was applied to polyethylene-backed wraps that were fastened to the below-ground portions of unseasoned southern pine pole stubs. After 4 years of exposure in Mississippi, the untreated control stubs were completely deteriorated....

Alternative technologies for wood wastes recycling - Part B: Biotreatment of PCP- and creosote-treated wood
1998 - IRG/WP 98-50101-18 b
Alternative technologies have been investigated to detoxify treated wood. Two classes of organic compounds are studied. Creosote-treated wood are classified in France as dangerous wood wastes. A conventional incineration could be provided for these wood wastes but the cost of this elimination could be very high (> 2000 FFR/ton). For these reasons, we have tested two kinds of new processes as al...

In service performance of wood sound abatement barriers
2024 - IRG/WP 24-41006
Sound abatement barriers made form treated hem-fir in service near Vancouver, Canada were inspected after about 10-12 years in service. The barriers appeared in good condition and no boards were to the point of needing replacement. The sound abatement decibel readings at all locations indicate they perform as well as concrete barriers and exceed the 5 dBA regulatory requirement for noise reduction...

Durability of wood in the area of wood-inhabiting termites in Slovenia
1981 - IRG/WP 1139
This report describes a research dealing with resistance and durability of five different species of wood. The experiment was made in natural conditions in the Slovene area of wood-inhabiting termites. The results of our experimental field, which correspond to the results of the former laboratory experiments, show a very weak resistance of spruce-wood, fir-wood, and beech-wood. They also show thei...

Development of an Australasian protocol for assessment of wood preservatives
1994 - IRG/WP 94-20043
The Australasian Wood Preservation Committee (AWPC) is currently developing a suite of assessment procedures (protocols) for the biocidal efficacy of wood preservatives for approval in Australasia (Australia, New Zealand, Papua New Guinea, Fiji). Protocols are being prepared for the six hazard levels recognised in the relevant standards of member countries and represent the minimum procedures requ...

Wooden windows, avoidance of damage via constructional measures
1990 - IRG/WP 3591
Increasing awareness of the environment reinforces the trend to use wood as a building material for windows in modern building constructions. Wood is a natural building and construction material. Under certain circumstances such as persistent humidity exceeding 30%, wood is rapidly degraded by decay fungi into CO2 and inorganic salts. The cost caused by damage (e.g. replacement of windows) represe...

Laboratory determination of the natural decay resistance of some lesser-utilized timbers from Tanzania against wood decay fungi
2004 - IRG/WP 04-10517
Four lesser known/utilized timber species (sap and heartwoods) from Tanzania, namely Albizia lebbeck, Zanthoxylum gilletii, Faurea saligna and Parinari curatellifolia were exposed to the brown rot fungi (Gloeophyllum trabeum and Coniophora puteana) and the white rot fungus (Coriolus versicolor) to determine their natural decay resistance according to the EN 113 standard procedure. The timbers were...

Fluoride woodpill
1987 - IRG/WP 3431
Decay problems of spruce joinery in the Netherlands in the 1960's and 1970's led to the introduction of preservative treatment. Because of the known penetration difficulties with Spruce, the results of the treatments were not always successful. The fact that the decay was found only in the joints led to development of the philosophy of "local preservation" of the joints in remedi...

Comparative environmental impact analysis of telecommunication utility poles: Treated wood and fibreglass
1999 - IRG/WP 99-50136
This study is aimed at providing the information necessary to assess the main environmental implications of different materials utilised in construction of utility poles. The study was performed on fibreglass and CCA treated poles timber. The work has been carried out by identifying and quantifying energy and materials used and wasted released during the entire life of the pole. The interactions w...

Evaluating the potential of modified wood for use in marine environments using a short-term laboratory bioassay
2004 - IRG/WP 04-10525
Chemically modified wood may be an alternative to preservative treated timber for marine structures. In this study a screening laboratory test using the wood-boring isopod crustacean Limnoria quadripunctata was used to assess the durability of chemically modified Pinus sylvestris, Pinus radiata and Picea sp. Most of the treatments used a combination of one of two of types of the resin dimethyloldi...

A summary of work carried out to compare natural and artificial weathering for preconditioning test specimens in testing anti-stain chemicals for wood in service
1976 - IRG/WP 266
Since 1972 work has been in progress within CEN to establish a European standard for the testing of wood preservatives designed to prevent blue-staining of wood in service. The method is based on the Butin test and involves pre-weathering of the samples prior to biological testing. The weathering regime employed is 6 months outside exposure from March to October. This imposes severe limitations on...

Soft rot decay of Eucalyptus maculata Hook. in different soils from Queensland, Australia
1980 - IRG/WP 1113
In the present work, different Queensland soils were chosen and their gross effects on the decay of treated and untreated Eucalyptus maculata examined. The soils were also amended with various levels of phosphate to study the response of the wood decay mycota to an increasing supply of this nutrient. Phosphate amendment was chosen because of the wide-scale use of superphosphate on Queensland soils...
