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

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