How it is recorded
The waste transfer note records the waste by its EWC code, along with the quantity, the time and place of transfer and the details of both parties. The EWC code lookup tool confirms a code before it goes on a note, and the guide to EWC codes on waste transfer notes explains how the codes are chosen.
From October 2026, permitted receiving sites in England and Wales record every load on DEFRA's Digital Waste Tracking Service (DWTS), with Scotland and Northern Ireland following in January 2027. The EWC code is part of that submission.
