Hazard classification of waste: Review of available practical methods and tools

Abstract

The different steps for the classification of waste as hazardous are the collection of information, the use of the European list of waste, the sampling, the analysis, the tests, the hypothesis of speciation of elements into mineral substances, the collection of hazard statement codes of substances, and finally, the comparison of weighted sum or maxima of concentrations or tests results with given concentration limits for each hazard property, or possible use of now available internet sites. Practical methods are suggested: tables for generic classification of elements, for “worst case with information” speciation hypothesis of elements into mineral substances, tests for hazardous property HP 1, HP 2, HP 3, HP 12, HP 14, methods for HP 9 and HP 15.
