Large volumes of preservative-treated wood are decommissioned each year. Historically, the most common treatment options for this material were either incineration or landfilling. Neither option is particularly economically viable or without potential adverse environmental consequences. Thus, recycling options, both removal of the toxic preservatives from the preservative-treated wood and recycling of the detoxified preserved wood, are of great importance to those concerned with the life-cycle management of treated wood. Moreover, there is great economic development potential if a cost-effective recycling system can be successfully developed.
