In countries affected by the problems described above, it is vital to be able to identify hazardous wastes at the place of generation and to have knowledge of the associated hazard potential, in order to control these hazards effectively within the framework of waste management planning and to put the planning into practice. Therefore a binding schedule of waste types must be compiled in preparation for the further stages of planning and implementation of waste management measures. Demarcation criteria and definition questions must be formulated for maximum harmonisation with existing international regulations, so as to control transboundary movements of waste materials within the meaning of the Basel Convention (see Section 2. and Annex 1) as far as possible from this side of the border.
