Abstract:
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.
