A new method for the study of microbiological decay of wood in a strictly anaerobic environment
1988 - IRG/WP 2319
Recent work has suggested that strictly anaerobic bacteria may play a role in the biodeterioration of wood, particularly in aqueous environments. However, no suitable test methods exist for the investigation of this hypothesis. An aqueous minimal medium in specifically adapted conical flasks was sterilised, gassed using a 5.5% H2; 31.8% C02; 62.7% N2 gas mixture to remove oxygen and transferred to...

An Historical Roof Timber System in the Old Town of Berlin-Spandau
2019 - IRG/WP 19-10949
In Europe the “Charter of Venice” was enacted on the 31st of May 1964. It is the international directive for the preservation of historic buildings and monuments. All countries in Europe now involve professional wood scientists and engineers in maintaining and preserving historical buildings. Here we discuss a restoration project involving 17th century roof timbering. This project may be used ...

Incising to improve penetration and retention of creosote in small-diameter Kenyan-grown Cypress (Cupressus lusitanica)
2003 - IRG/WP 03-40253
Turning small-diameter plantation thinnings into value-added products has remained a challenge in many countries, including Kenya. The present study reports on a feasible technique to effectively treat small-diameter cypress for use in ground contact. Samples of pole-size Cypress (Cupressus lusitanica), 106 mm and 138 mm in average diameter, were sampled from thinnings in 7 and 12 year-old plant...

The environmental chemistry of chromium: Science vs. U.S. law
1993 - IRG/WP 93-50014
The cooperation which existed among chromium chemical producers, industrial health laboratories, and governmet agencies was destroyed after 1970 by the advent of environmental activism and regulatory legislation. As prewar plants had been found to pose a serious cancer risk, this fact was the basis of EPA regulations, especially during the term of Joe Califano in HEW under Jimmy Carter. However, a...

Management of treated wood waste in Canada - Technical and regulatory solutions
2001 - IRG/WP 01-50166-15
A major problem facing the wood preservation industry in Canada is the management of wastes. This refers to wastes generated during the treatment process as well as waste treated wood that is removed from service. The volume of oil borne preservative treated industrial products to be removed from service in Canada over the next 20 years is expected to be fairly constant at approximately 350,000 to...

Use of a stainless steel mesh to exclude formosan subterranean termites
1997 - IRG/WP 97-10199
Physical barriers are gaining in popularity world-wide as methods of preventing subterranean termite penetration and attack on structures. Sized particle barriers of crushed basalt or granite are approved for use in building construction in Hawaii and Australia. TERMI-MESH, a marine grade 316 steel mesh, was recently developed in Australia and is approved there, and now in Hawaii, for use as a ter...

An evaluation of chemical treatments for the protection of radiata pine logs from fungal degrade
1986 - IRG/WP 3377
Busan 30, Busan 1009, Mitrol PQ375. and sodium pentachlorophenoxide (NaPCP) plus have been evaluated as antisapstain treatments for the long-term protection of debarked radiata pine logs. After 3 months' winter-spring storage, treated debarked logs had less surface and internal sapstain than 'control' logs. After 6 months' storage all logs had internal sapstain ...

Copper leaching from Kemwood ACQ and Embalit CBC treated wood products
2000 - IRG/WP 00-50150
TNO has performed a study on the leaching of copper from Kemwood ACQ and Embalit CBC treated wood products, further referred to as ACQ and CBC. The sawn dry wood has been impregnated using an industrial vacuum-pressure process with ACQ (with or without Ultrawood 4) or with CBC, under supervision of Flexchemie B.V. After treatment samples have been transported and subjected to leaching tests at TNO...
