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.
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.
Code 08 01 11* is the mirror hazardous entry for waste paint and varnish containing organic solvents or other hazardous substances. Composition remains central for mixed residues, washings and dried material.
This is the hazardous side of a mirror entry. The actual composition and assessment determine which entry applies.
The correct List of Waste code depends on the activity and process that produced the waste and, where required, the evidence supporting its classification.
Code 13 05 07* is the absolute hazardous entry for oily water from oil-water separators. The guide distinguishes oily water from the other waste fractions produced by separator servicing.
WM3 identifies this as an absolute hazardous entry. Confirm the waste fits the description and source activity.
The correct List of Waste code depends on the activity and process that produced the waste and, where required, the evidence supporting its classification.
Code 15 02 02* covers specified absorbents, filters, wiping cloths and protective clothing contaminated by hazardous substances. Classification depends on the contaminant and the waste-producing activity.
This is the hazardous side of a mirror entry. The actual composition and assessment determine which entry applies.
The correct List of Waste code depends on the activity and process that produced the waste and, where required, the evidence supporting its classification.
Code 16 05 06* is the mirror hazardous entry for laboratory chemicals consisting of or containing hazardous substances, including mixtures. The guide covers identity, composition and classification evidence.

The correct List of Waste code depends on the activity and process that produced the waste and, where required, the evidence supporting its classification.
Code 20 03 06 is the absolute non-hazardous entry for waste from sewage cleaning. The source activity, rather than the collection equipment, determines whether the description fits.
WM3 identifies this as an absolute non-hazardous entry. Confirm that the waste fits this entry rather than another description.
The correct List of Waste code depends on the activity and process that produced the waste and, where required, the evidence supporting its classification.
01 01 01: wastes from mineral metalliferous excavation
EWC / LoW 01 01 01
This is a WM3 absolute non-hazardous entry. For waste that fits the official description and source activity, the non-hazardous status is fixed; waste from a different source or of a different type may require another code.
WM3 reference information. A matching description alone does not establish the correct classification for a particular waste.
