Special treatment: disposing of CCA-treated wood.
B uilding outdoor structures such as decks, docks, and playgrounds often signifies the pursuit of a more healthful lifestyle, but the wood used in much of this construction poses potential environmental and health problems when these structures are demolished. The chemicals that preserve the wood, primarily the inorganic waterborne preservative chro-mated copper arsenate (CCA), are designed to ...
متن کاملBacterial Biodegradation of CCA-Treated Waste Wood
As wood treated with chromated copper arsenate (CCA) is removed from service, methods for eliminating toxic metals from the wood are needed. CCA-tolerant bacteria were evaluated for their ability to modify CCA-treated wood. Aerobic bacteria were isolated from a 20-year-old test plot of CCA-treated stakes. Bacteria selected for their ability to grow on nutrient agar containing CCA components, we...
متن کاملPreservative 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...
متن کاملProperties of particleboard made from recycled CCA-treated wood
Recovery of chromated copper arsenate (CCA)-treated wood for reuse has been the focus of several international research groups due to the imminent disposal problem created when large quantities of CCA-treated wood ultimately come out of service. Bioleaching with Bacillus licheniformis CC01 and oxalic acid extraction are two methods known to remove significant quantities of metals from CCA-treat...
متن کاملFormation of Dioxin during Smoldering of CCA Treated Wood Char
Production of dioxin during the smoldering of wood char containing chromated copper arsenate (CCA) was investigated. Preliminary results are presented for the smoldering of treated wood char at 300 and 400°C, as a function of char loading, smoldering time and inlet oxygen concentrations. PCDF (mainly Cl4DF) were the preferred products of smoldering, and the results indicate the dependence of PC...
