EWC codes and waste classification support for UK industrial waste
Recircled Resources helps industrial producers identify the correct EWC or List of Waste (LoW) code, assess hazardous properties where required and build a defensible waste classification using WM3 principles. The aim is not just to choose a code, but to support compliant handling and realistic recovery, treatment or disposal routes.
Start with the process that generated the waste.
An EWC code, also referred to as a List of Waste or LoW code, is the six-digit code used to classify a waste stream. Choosing the correct code starts with the process that produced the waste, not simply the name or appearance of the material. Some wastes also require a WM3 assessment to determine whether hazardous properties apply.
Identify the production process
Waste codes are organised around source activities and material types. The correct chapter and entry depend on how and where the waste arose.
Describe composition accurately
Process knowledge, raw-material information, SDS documents and representative analysis can all be relevant to a defensible classification.
Check whether WM3 assessment is needed
Mirror entries can require assessment of hazardous properties before the hazardous or non-hazardous code can be selected.
What an EWC or LoW code actually does.
The waste classification code identifies the relevant entry in the List of Waste. The correct code must be supported by an accurate description of the waste and, where relevant, an assessment of hazardous properties. A code chosen without evidence can create problems later with carriers, processors, documentation and outlet acceptance.
Evidence-led waste classification that supports the route.
Define
Review the source process, current description, proposed outlet and the classification question that needs resolving.
Gather evidence
Use process information, SDS data, specifications and analysis appropriate to the material and potential hazards.
Assess
Apply the List of Waste and WM3 principles, including hazardous-property assessment where relevant.
Apply
Use the classification to support correct paperwork, outlet discussions and the wider waste route.
What is an EWC code?
An EWC code is the six-digit code used to identify a waste type within the List of Waste. In UK practice, EWC code and LoW code are commonly used to describe the same classification system.
How do I find the correct EWC code for my waste?
Start with the process that generated the waste, then identify the relevant List of Waste chapter and entry. The material description, composition and any mirror-entry requirements must also be considered rather than choosing a code by name alone.
What is a WM3 waste assessment?
WM3 is the technical guidance used to classify waste and assess hazardous properties. It is particularly important where a waste could fall under hazardous or non-hazardous mirror entries.
Is WAC testing the same as waste classification?
No. Waste Acceptance Criteria testing and waste classification answer different questions. Classification should be completed independently using the appropriate evidence and WM3 principles.
Do I always need laboratory analysis?
Not always. Evidence should be proportionate to the stream and the uncertainty. In some cases process knowledge and product information are strong; in others targeted representative analysis is essential.
Can you help with industrial waste classification services?
Yes. We can review the process, existing EWC code, analytical information and proposed route, then identify what further evidence or WM3 work is needed to support a defensible classification.
Start with the process, material and any existing analysis.
We can assess what information is missing and whether classification work could help unlock a compliant, commercially workable route.
