EWC Codes Describe the Waste, Not the Skip
An EWC code—also called a List of Waste code—is a six-digit classification for waste. The correct code depends on the source, composition and properties of the waste, not whether it arrived in a 6-yard or 8-yard skip.

What is an EWC code?
EWC is the familiar name for codes in the List of Waste. Environment Agency WM3 guidance explains how to assess and classify waste and includes the code list in Appendix A.
Some entries are absolute hazardous or non-hazardous entries; mirror entries require assessment of composition and hazardous properties.
Why a skip product cannot choose the code
A storefront product such as mixed builders' waste is a commercial description, not a complete chemical or regulatory assessment. Different loads sold under similar names can require different treatment when their actual contents differ.
- Ask about the source
- Describe the waste accurately
- Identify contamination
- Escalate uncertain or hazardous loads
- Keep the basis for the decision
How Rubbleo uses the code
Operators can configure waste types with an EWC field and carry the selected value into jobs, driver information and waste records. This reduces re-keying but does not turn Rubbleo into a classification engine.
When to get competent advice
Use official WM3 guidance and competent waste-classification advice when the waste is uncertain, potentially hazardous, contaminated or subject to persistent organic pollutant controls. Never select a convenient code simply to complete a software field.

Are EWC and List of Waste codes the same thing?
The terms are commonly used for the same six-digit waste classification codes. Current official guidance often refers to List of Waste or LoW codes and notes the EWC terminology.
Can software automatically choose the correct code?
Software can present configured options and retain a selection, but it cannot safely replace the assessment of the waste's source, composition and hazardous properties.
Does an asterisk matter?
Yes. An asterisk identifies a hazardous waste entry. Classification and the resulting controls require appropriate assessment.
