Abstract

This study focuses on the identification, classification and encoding of hazardous generational wastes aimed at running a comprehensive waste management, on an RCRA basis, in the greatest Middle East oil unit at Ahvaz Karun Oil and Gas production unit no.02. To achieve such a purpose, a 154-test questionnaire analysis, drawings of units, standard experiments, comparison of the chemicals found in the wastes with 8 lists of hazardous materials available in standard international checklists and determination of the number of materials available per checklist have been put into practice. The results of this research undertaken for the first time in Iran, reveals that: 33 kinds of toxic hazardous wastes, five kinds of non-hazardous materials and 25 types of as yet unproven wastes were detected; among these, 3 kinds of them were placed in acute hazardous wastes, four in toxic hazardous wastes, 4 in hazardous wastes from definite sources, 8 in priority toxic materials, 6 on the US Environmental Protection Agency (EPA) checklist and 10 in the toxic TCLP toxic checklist. Six heavy metals, namely nickel, lead, zinc, copper, chromium and cadmium, are categorized as toxic materials. Finally, waste water centrifugation was recommended to prevent the factory offshore soil becoming polluted with hazardous materials and bioremediation to purify the contaminated soils; the final waste management for each group of hazardous and non-hazardous wastes was determined.
