842 reference records · 8 detailed guides

This reference index contains all 842 six-digit entries in the WM3 GB waste-classification reference. An asterisk identifies a hazardous entry. Mirror entries need the relevant hazardous-property assessment before the correct member of the pair can be selected. Code selection is based on the activity and process that produced the waste, not simply on words that happen to match a description.

Waste classification is separate from dangerous-goods transport classification and from a receiving facility’s acceptance checks. WM3 GB applies in England, Scotland and Wales; Northern Ireland uses its own WM3 version and regulatory arrangements.

Code descriptions are reproduced from WM3, with Crown copyright material used under the Open Government Licence v3.0.

Finding the correct List of Waste code

Search by waste description or six-digit code. Spaces and hyphens are accepted. Chapter and WM3 entry-type filters narrow the list, but code selection still depends on the activity and process that produced the waste.

  • Waste origin: the business activity and process that produced the material.
  • Composition: known substances, contaminants and representative analysis where available.
  • Code information: the full six-digit entry and any hazardous asterisk shown in existing records.
  • Waste movement: quantity, container type and the documentation required before collection.
Reference sources for the waste code library

These sources explain the WM3 classification framework, legal responsibilities for waste classification and general pollution-prevention duties. They are reference material only. The correct classification depends on the waste itself and the jurisdiction in which it is produced.
