Cancer incidence among CCA exposed workers in the wood preserving industry
1995 - IRG/WP 95-50040-09
CCA wood preservatives - Copper, hexavalent, Chromium and tri-or pentavalent, Arsenic - has been used in the Nordic countries since mid 1930. Trivalent arsenic and hexavalent chromium compounds are toxic and cancerogenic while pentavalent arsenate and trivalent chromium are less hazardous. In impregnation, the compounds of CCA are fixed in the wood as insoluble trivalent chromium and copper pentav...

The wood preservation industry in Kenya
1997 - IRG/WP 97-30157
Like in many other tropical and sub-tropical countries, the necessity to protect wood using wood preserving chemicals was not found necessary in Kenya because of abundant supplies of naturally durable hardwoods. That situation changed as a result of depletion of natural hardwood forests and replacement by fast growing non-durable exotic species and the appearance of new, more lucrative markets for...

The limitations of legislative information distribution to the UK remedial preservation industry
1995 - IRG/WP 95-50060
The remedial preservation industry in the UK consists of companies that are rarely large enough to fit any of the definitions of small to medium enterprises (SMEs). They are faced with information on a wide range of legislation related to their industry from a bewildering variety of sources. Costs range from free to hundreds of pounds. Recent surveys have shown that a significant proportion of SME...

Electrodialytic remediation of a soil from a wood preservation industry polluted by CCA
1998 - IRG/WP 98-50101-14
Soil contamination is often found at wood preservation sites due to spills, dripping of excess preservatives and deposition of sludge associated with dissolved salts of copper, chromium and arsenic (CCA). The electrodialytic process is a promising heavy metal soil remediation technique. It is based on a combination of the electrokinetic movement of ions in soil with the principle of electrodialysi...

Future termite control requires partnership between industry, government and people
2006 - IRG/WP 06-10586
Given the behaviour of the pest control industry, together with the housing and timber industries, and performance of the State regulatory agencies, it is not surprising that all of these groups were philosophically ill-prepared to consider alternative measures in June 1995. However, conditions have altered and there is an awareness of such alternatives. In future, termiticides will have propertie...

Estimating the age of subterranean termite attack and damage in buildings
2010 - IRG/WP 10-10727
This paper describes physical and experimental methods and a mathematical model (Rotramel 2003) to assist in estimating the age of subterranean termite attack and damage to building structures. Timber, building and termite management industries have to develop new strategies to assess and estimate termite attack and damage in the current climate of global warming. A case study will be used as an e...

Towards better integration of wood protection in the forestry wood industry chain - a case study on hybrid poplar
2019 - IRG/WP 19-50359
Wood and wood products are limited in service life as in the forest ecosystem trees at end of their life are degraded to re-enter the bio-geochemical cycle. Humans can select wood species with a level of natural durability fit for an envisaged end use. Mainly those applications that require a long service life under conditions that are similar to those at soil level in a forest ecosystem have been...

Wood natural durability an asset to the circular economy of wood industry: valorization of waste from sawmills for the cosmetics sector through the ValorExtr@ct project
2019 - IRG/WP 19-10954
The French Guiana ‘s forest is characterized by its incredible biodiversity; more than 1200 wood species have been listed to date. Some argue that this diversity would be linked to the hot, humid climate with no seasonal variation, which would be ideal conditions for the installation of a constant "arms race" between predators and prey. Thus, to cope with biotic and abiotic attacks, wood species...
