European mine waste management is governed by the Extractive Waste Directive (2006/21/EC) but hazardous assessments are conducted according to a broader hazardous classification legislation encompassing all waste types. Consequently, there is a risk of misinterpretation when using one system for all wastes.

This article assesses potential issues with the current approach. Literal interpretation of the legislation could over-emphasise or under-estimate risks and hazardous classification focuses on solid phase compositions, with minimal consideration to leachate formation over time.

Correct designation of waste is essential; it influences waste management plans and has implications for categorisation of mining waste facilities. Tailoring each sitespecific assessment is crucial and a variety of information sources and legislative documents should be consulted to provide the most relevant classification.
