EWC stands for European Waste Catalogue. The codes are used to define different types of waste. In regards to EWC there is no difference between regular waste paper and confidential paperwork as they are the same material so you can use the same EWC code for both. The disposal method, however, needs to ensure confidential paperwork is disposed of in a secure manner to comply with legislation. Confidential paperwork should be disposed of using on-site mobile shred trucks to ensure the shortest chain of custody.
