Overview
Waste Wood is wood which is not virgin timber (that is, wood that has been used for any purpose) and associated residues such as off-cuts, shavings chippings and sawdust, either treated or not treated, is waste. They remain waste and subject to waste regulatory control until completely recovered[1].
Where virgin wood is mixed with waste wood such as fence posts, pallets, construction boarding or other waste, the mixed load is considered waste[1].
Treated waste wood is wood that has been treated by being injected, impregnated, sprayed, infused (soaked) or surface coated with any organic or inorganic substances for the purposes of preserving or protecting it or for changing its appearance. Some of these treatments may not be obvious and visible. Surface coating includes varnishes and paints, glues and non-natural veneers[1].
Waste Wood is categorized into 4 different types; Grade A-D. This is based on the quality of wood, the utilisation of the wood, and type/amount of contaminants[1].
