Understanding EWC Codes: A Complete Guide for UK Waste Producers
European Waste Catalogue (EWC) codes — sometimes called LoW (List of Waste) codes — are the foundation of waste classification in the UK. Every business that produces waste must identify the correct code before the material can be stored, transported, or disposed of legally. Incorrect coding can lead to rejected loads, enforcement action, financial penalties and, in some cases, prosecution.
Why EWC Codes Matter
EWC codes exist to ensure that waste streams are classified consistently across Europe and the UK. The six-digit code tells you:
- What type of waste it is (e.g., construction, municipal, commercial).
- Whether the waste is hazardous or non-hazardous.
- What regulations apply, including Duty of Care and consignment requirements.
- Which licensed sites can legally accept the waste.
Correct Example EWC Codes
- 17 02 01 — Wood from construction and demolition activities (non-hazardous).
- 20 03 01 — Mixed municipal waste, commonly produced by businesses and households.
- 16 01 03 — Used or end-of-life tyres (Chapter 16: wastes not otherwise specified).
How to Identify the Proper EWC Code
Follow the government’s recommended three-step process:
- Identify the source activity. For example, construction, manufacturing, healthcare, ELV dismantling etc.
- Check the chapter and sub-chapter descriptions.
- Identify the correct six-digit code.
If the waste appears in more than one chapter, you must use the chapter relating to the original process that created it. If you misclassify waste, the receiving site may reject the load or require a revised transfer note before tipping.
