For the management of wastes and the decision to either dispose or usethem, more information on the environmental properties of materials is needed. Leaching tests have been developed to assess those properties. Originally leaching tests have been designed in relation to regulatory tools, not as instruments to guide the management of wastes and the possibilities to improve material properties. New methods have been designed to address these aspects, in which maximum benefit can be derived from the knowledge of systematic behaviour of materials. Since the same type of residues are produced in many countries, the existing knowledge in some countries can be used as a starting point in other countries where the development of tests is not that advanced. After initial detailed characterization, concise procedures can be used for control purposes focussed on the typical leaching factors controlling aspects of certain residue streams. Examples of existing knowledge in this field are presented. 13 figs., 5 tabs., 24 refs.
