Note: The latest independent TAC (Technical Adaptation Committee) report has recognized that many Member States are facing serious problems with the implementation of this Directive even though most had now transposed its requirements into domestic legislation.

The Department of Trade and Industry (DTI) in the UK has played a major part in the original proposal, development and implementation of the WEEE Directive. The DTI web site includes non-statutory guidance notes for the WEEE Directive (includes the WEEE decision tree). This is a useful document.
