Waste Wood Classification – How To Categorise Your Waste Wood

Whether you work at a skip yard, a demolition site or a waste transfer station, if you work with demolition waste wood, it is your legal duty to identify potentially hazardous waste wood and action it accordingly under the Waste Wood Classification guidance.

What is Waste Wood Classification?

Waste Wood Classification is the process of ensuring that material is properly classified at its origin and is processed into appropriate end markets. By classifying waste wood, we can identify which items are hazardous in accordance with WM3 guidance and ensure they are dealt with appropriately.

What Are ‘Potentially Hazardous’ Items?

Potentially hazardous items include fence posts, decking and certain types of waste wood from pre-2007 buildings including roof timbers, external joinery and tiling battens.

Following the withdrawal of Regulatory Position Statement 250 (1st September 2023), the list of potentially hazardous materials has been updated to include: Barge boards, facias, soffits, wooden windows, conservatories and doors, roofing timbers, tiling/cladding battens and timber frames/joists.

This doesn’t apply to materials such as railway sleepers and telegraph poles, which are already known to be hazardous and always require specialist waste treatment.

How can I Classify My Waste Wood?

First IDENTIFY the type of wood using the WRA quick guide. Once this is done, a sample of the whole piece of the item should be taken (a cross-section from the middle no smaller than 150mm long) which can be sent to an accurate and reliable laboratory for TESTING. Only after this should you determine whether you should ASSIGN or CONSIGN your materials.

What If My Waste Wood Is Hazardous?

If your waste wood is deemed Hazardous, it must be consigned using a Hazardous consignment note. This needs to be completed fully, detailing the weight of the specific items. These items should be segregated and only when segregation is not practical can they be blended within a non-hazardous wood load.

Following this process, these materials can then be sent to a wood reprocessor, where they can be blended into material which can then be used for IED Chapter IV compliant biomass energy plants or the manufacture of panel boards.
