An EWC Code is a six-digit code used to identify waste as listed in the European Waste Catalogue. It is formatted as three pairs of numbers, for example 12 34 56. It identifies and classifies waste into categories according to how these wastes have been produced. It adequately describes the waste being transported, handled or treated.
It can also be referred as a LoW Code (List of Waste Code).
