Notes on EWC Codes
Important: When choosing an EWC code to classify your waste, you must ensure that each of the EWC chapter description, sub chapter description and the EWC code description itself, match the waste stream you are handling.
Hazardous Waste: If an EWC code ends with an asterisk (*), this indicates that the waste is considered to be Hazardous Waste.
