1001) Research on Termites Damage ot Untreated Wood and Preservative Treated Wood(Materials, Execution)

Preservative leaching from weathered CCA-treated wood.

Disposal of discarded chromated copper arsenate (CCA)-treated wood in landfills raises concerns with respect to leaching of preservative compounds. When unweathered CCA-treated wood is leached using the toxicity characteristic leaching procedure (TCLP), arsenic concentrations exceed the toxicity characteristic (TC) limit of 5mg/L in most cases. The majority of discarded CCA-treated wood, howeve...

Assessing Potential Waste Disposal Impact from Preservative Treated Wood Products

The management of discarded treated wood products upon disposal is one of the many factors that should be considered when evaluating a new wood preservative or when comparing wood preservatives as part of a life cycle assessment. Future environmental ramifications of disposal, as well as regulatory requirements and costs, must be assessed and weighed. This paper presents an overview of the fact...

Improvement of the Durability of Heat-treated Wood against Termites

Thermal modification is an attractive alternative to improve the decay durability and dimensional stability of wood. However, thermally modified wood is generally not resistant to termite attacks, limiting the field of application of such materials. One way to overcome this drawback is to combine thermal modification treatment with an additional treatment. One such treatment is the impregnation...

Application of Near Infrared Spectroscopy to Preservative-Treated Wood

Near infrared (NIR) spectroscopy is now a widely-used technique in the field of forest products, especially for physical and mechanical property determinations. This technique is also ideal for the chemical analysis of wood. There has been a growing need to find a rapid, inexpensive and reliable method to distinguish between preservative-treated and untreated waste wood. It has been demonstrate...

Potential for Introduction of Preservative Treated Wood in Wood Waste Recycling Streams and its Prevention
