The European Waste Catalogue
The European Waste Catalogue (EWC) classifies waste materials and categorises them according to what they are and how they were produced.
The UK and other member states are fulfilling their requirement to integrate the catalogue into their domestic legislation. One example of this in the UK is the requirement to make a reference to the 6-digit EWC code on all Duty of Care Transfer Notes.
