Correct hazard classification of waste is crucial to provide sustainable and lawful management plans, from transport to final disposal. Especially in the case of waste classified as “mirror entry” in the European List of Waste, the choice of the specific assessment tool or method is a key step to ensure the transparency and reliability of the process.
Directive 2008/98/EC defines waste as hazardous if characterized by at least one of the 15 hazardous properties (HPs).
The assessment of the specific HP can be based on the measured content of potentially hazardous substances or on the result of a test of a given property. Here, a tiered assessment is recommended:
– 1st tier: Waste should be classified according to the European List of Waste (LoW) as “hazardous”, “non-hazardous”, or as “mirror entry”. In this latter case:
– 2nd tier: Some HPs can be assessed as through the so-called expert judgment;
– 3rd tier: The remaining HP can be assessed according to the total concentration of specific waste constituents under a “worst realistic case” hypothesis.
– 4th tier: If the “worst realistic case” approach leads to unsatisfactory or unrealistic results, a 4th tier can be performed by carrying out direct analytical methods, specifically developed for the target HP.
