In search of excellence - A necessary challenge
1990 - IRG/WP 3567
Consumerism and environmentalism are gaining much influence. At national and E.C.-level the policy conducted is based on prevention of pollution through "sound" wood preservatives. Supposing that "environmental friendly" products do not exist it is understood that "sound" products have least effect on the environment during their whole life cycle. In the past only the effectiveness was paramount, ...

Recovery of copper, chromium, and arsenic compounds from the waste preservative-treated wood
1991 - IRG/WP 3651
In Japan, about 40 percents of waste wood is incinerated and the residue is dumped into the landfill site. The waste preservative-treated wood, which is mixed in nontreated wood, is incinerated in the same way, too. However, it will cause the serious problems that the gases contained with high concentration arsenic compounds are discharged from the smokestacks of the incineration facilities and th...

Technologies for the Management of Wood Waste Containing Metals-Based Preservatives
2005 - IRG/WP 05-50224-16
Disposal of the metals from preservative treated wood can occur through two general strategies: “removal and confinement” or “dilution”. The acceptability of each of these two choices is typically dictated through the disposal regulations of a particular region. A considerable amount of research has been conducted to develop new and innovative “removal and confinement” technologies...

Minthea rugicollis (Walk.) (Coleoptera: Lyctidae): A pest of rubberwood
1992 - IRG/WP 92-1570
Rubberwood (Hevea brasiliensis) has grown in prominence as a source of timber in recent years. One of the drawbacks in the utilization of this species is its susceptibility to attack by powder-post beetles belonging to the family Lyctidae. In Malaysia, Minthea rugicollis (Walk) is the, most commonly found species attacking seasoned rubberwood. In this paper, information available thus far on Minth...

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...

Practice Makes Perfect: A Biodeterioration Diagnostics Database that Makes Practice
2008 - IRG/WP 08-10648
Replacement of bio-based materials deteriorated by pests costs billions annually and wastes natural resources. Wood replacement rates have remained relatively stable despite significant advances in wood preservation. This may be explained, in part, by poor end-use by uninformed users and by inadequate pest management once products are in service. This problem may be exacerbated by two opposing fac...
