A second life for old treated wood

(Institut national de la recherche scientifique - INRS) Every year, several thousand tons of treated wood waste is buried, incinerated, or mixed with untreated wood waste. The management of this waste is problematic because treated wood contains preservatives such as arsenic, chromium, and copper to slow its deterioration. To remedy this, INRS researchers have found a simple, effective, and environmentally friendly solution. They have developed a process that successfully removed more than 90 percent of the contaminants present in treated wood waste in experiments conducted on a small scale in the laboratory.
