Description:
Waste wood collected at the Vancouver landfill has been sorted based on the visibility of coatings, paints, and the green colorization of wood typically associated with wood preservatives. The sorted material was then ground and tested with an inductively coupled plasma mass spectrometry (ICP–MS) for heavy metal elements that are toxic or harmful to humans and (or) the environment. Results indicated that wood preservatives were not visually detectable but paints and coatings were. Therefore, the study demonstrated that visual sorting is not sufficiently accurate to distinguish between treated and clean or untreated waste wood.
