Title: Overview of residual waste treatment technology
Abstract: The treatment and disposal of industrial residual wastes is now receiving increasing attention by federal and state environmental agencies. New federal and state laws impose a set of stringent requirements for management of waste especially hazardous streams. Proper hazardous waste management practices involve one or more of the following: recycling and reuse of waste; removal of toxic or hazardous components; reduction of volume; conversion of toxic waste to nonhazardous by physical and chemical treatment or stabilization, biological, or thermal processing; burial of toxic waste in secure landfills; and/or burial of detoxified or stabilized waste in sanitary landfills. In matching a waste stream with a treatment process, the following must be considered: waste characteristics, objectives of treatment, technical adequacy of treatment process, economics, and environmental considerations. For wastes that are generally recognized as potentially hazardous, most conventional waste management practices are inadequate in terms or providing sufficient health and environmental protection. Some generalized waste treatment categories are presented. Even though the available options for a specific hazardous waste may be limited to one or two techniques which would provide complete protection to man and the environment, most industrial wastes are amenable to treatment by several techniques. All wastes should be investigatedmore » for the feasibility (and economic advantages) of in-process, at-source controls and modifications that will reduce the quantity and hazards. Resource recovery, both for energy and materials, should be evaluated for both short and long term attractiveness.« less
