This manual is intended to assist with the further training of decision-makers who have already—or are likely to have soon—direct responsibility for the management of hazardous waste. The manual is the result of collaboration between UNEP's Indus-try and Environment Programme Activity Centre (IE/PAC) and ISWA's Working Group on Hazardous Wastes (WGHW). A particular emphasis of this collaborative programme is on information exchange and training.
