The EWC is a list of waste descriptions divided into twenty main chapters. These chapters will have a two-digit code assigned to them between 01 and 20.
These chapters relate to different industries but some variations exist as some relate to materials and processes. Within these chapters, you will find a six-figure code for individual waste types.
In simple terms, an EWC code tracks what industry the waste is coming from and what type of waste is being disposed of.
