Definition: Waste wood is wood that has already been used and must now either be disposed of or employed as a secondary material.
Recycling: Waste wood can be used by the wood processing industry (e.g. to make chipboard) or as a fuel for thermal power stations.

- Treated wood – AIII grade waste wood Glued wooden furniture, coated or painted; waste wood from clearances of bulky refuse, etc.
- Treated wood – AIV grade waste wood Fencing, playground equipment, windows and exterior doors, parquet flooring, firewood, railway sleepers, structural timber, etc.
