Chromated copper arsenate (CCA)-treated wood
removed from service has been proposed as a source of
raw materials for wood composites such as particleboard
(PB), fiberboard, oriented strand board (OSB), laminated
veneer lumber (LVL) and wood cement bonded products
[1,2]. The problems associated with this recycling option
are the toxic fumes and air borne particles produced
during the cutting and machining of wood containing
heavy metals and the air quality during the hot pressing of
the composites [2]. Occupational exposure to copper,
chromium, and arsenic from wood sawdust may constitute
a health hazard.
