New Technical Guidance for Waste Classification

13 July 2015 by CSG

The way waste is assessed and classified in the United Kingdom has changed significantly and Environmental Agency guidance document WM3 is now in force, replacing WM2. This new document has been produced as a result of several changes to the law which include amendments to the List of Waste (or European Waste Catalogue), a major revision of hazardous properties and the adoption of a new system of chemical classification.

The assessment and classification of waste is based upon the List of Waste decision (2000/532/EC) and Annex III of the Waste Directive (2008/98/EC).

These in turn rely on chemical legislation for information on chemicals given in the Dangerous Substances Directive (67/548/EC) and the Dangerous Preparations Directive (1999/45/EC).

What are the changes from WM2?

Below, we list the changes made to the guidance document and what’s been kept consistent by the EA.

Chapter 2: Provides a framework that explains how to assess and classify waste.
