Waste Wood Classification

What is Waste Wood Classification?

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.

Waste Wood Classification Services can help you to determine the quantities and types of hazardous waste wood arising from your activities and the appropriate end markets based on the Regulatory Positioning Statement (RPS) 250.

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.

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

Further use

Following this process, these materials can then be sent to an RPS250 compliant 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.

If your waste wood is deemed Hazardous, it must be consigned using a Hazardous consignment note. These items should be segregated and only when segregation is not practical can they be blended with a non-hazardous wood load.
