Disposal of Pressure Treated Wood in Construction and Demolition Debris Landfill
2005 - IRG/WP 05-50235
Pressure treated wood is often disposed in landfills in the US, very frequently in construction and demolition (C&D) debris landfills. C&D debris disposal facilities in many states are not equipped with liner systems to protect underlying groundwater. In this paper, issues associated with the disposal of metal-containing treated wood in C&D debris landfills are discussed. C&D de...

Leaching of Arsenic from Mulch Made from Recycled Construction and Demolition Wood
2005 - IRG/WP 05-50232
Mulch made from recycled construction and demolition (C&D) wood has been reported to contain chromated copper arsenate (CCA)-treated wood and potentially release arsenic in the leachate by rainfall. Such recycled wood mulch is commonly masked with iron-oxide colorant, which is known to combine with arsenic. The objective of this study was to evaluate the levels of arsenic leaching from C&...

Metal Leaching from Pressure Treated Wood in Sanitary Landfill Leachate
2004 - IRG/WP 04-50220
Pressure treated wood products contain heavy metals to prevent biological decay. Scrap treated wood from construction activities and demolished structures containing treated wood are typically disposed in landfills. To examine the potential mobility of metals from pressure-treated wood disposed in landfills, wood samples were leached using leachate from lined landfills and the concentrations of ar...

Need to develop processing technologies (for value addition) of the species evaluated for their properties and uses
2005 - IRG/WP 05-40307
The demand of timber in India for different industrial as well as domestic applications is ever increasing mostly due to urbanization and industrialization. This demand can only be met either from the imported timber or from the plantation resources outside the reserved and natural forests. There are a number of timber species grown under plantation forestry have their heartwood refractory to any ...

Comparison of Temporal Changes in Metal Leaching and Aquatic Toxicity from Wood Treated with CCA and Alternative Preservatives
2005 - IRG/WP 05-50236
This study compares the temporal variation of chemical leaching and aquatic toxicity of wood treated with chromated copper arsenate (CCA) and other copper-based wood preservatives (alkaline copper quaternary (ACQ), copper boron azole (CBA), copper citrate (CC) and copper dimethyldithiocarbamate (CDDC)). Treated wood blocks were leached for 21 days and the leachate collected was analyzed for prese...

Speciation of leachates from CCA-treated wood
2005 - IRG/WP 05-50224-27
Different species of arsenic and chromium are characterized by different toxicities and different mobilities. The environmental impacts of CCA-treated wood would therefore be a function of the chemical forms of the metal releases. As a consequence a series of tasks were undertaken to evaluate arsenic and chromium species from CCA-treated wood. The intent of these tasks was to quantify the total...
