In Europe, the decision whether waste is hazardous or not is based on 15 properties, among them the HP 14 property (“ecotoxic”: waste which presents or may present immediate or delayed risks for one or more sectors of the environment). This document describes a strategy for assessing the HP 14 property, based on a combination of two approaches: the summation of classified compounds in the waste carried out according to the regulation on Classification, Labelling and Packaging of substances and mixtures (CLP) and the usage of the results of biotests performed on waste eluates and solid wastes. The proposal is based mainly on recommendations of an European ring test performed in 2007, the work carried out in the CEN/TC 292/WG 7 standardization working group and the results of various research projects regarding the ecotoxicological characterization of waste performed mainly in France and Germany. Examples are provided showing that, using this approach, a distinction between hazardous and non-hazardous wastes is possible, independently of which type of threshold values is used (currently, both Effect Concentrations (EC) or Lowest Ineffective Dilutions (LID) values have successfully been employed). Furthermore, a battery of tests (three using waste eluates, and three using solid waste samples, plus, under certain conditions, a genotoxicity test) is recommended for the ecotoxicological testing of wastes. We propose to consider this combined approach when defining the legal requirements for the ecotoxicological classification of wastes. Integr Environ Assess Manag © 2013 SETAC
