A COMPARATIVE ASSESSMENT OF INCINERATORS VERSUS LANDFILLS FOR HAZARDOUS WASTE MANAGEMENT Timothy G. Shea, Manager Engineering-Science Fairfax, Virginia 22030 Joe J. Mayhew, Manager Solid Waste Programs Chemical Manufacturers Association Washington, D.C. 20037 INTRODUCTION This paper presents the findings of an investigation conducted by the Chemical Manufacturers Association (CMA) to identify and evaluate decision factors affecting the selection of landfilling versus incineration to manage hazardous wastes [1]. The study addressed hazardous wastes from the organic chemical industry that can be managed by either technology. The inquiry process was designed to illustrate the decision factors by contrasting the technologies. Representative landfill and incineration designs are compared and evaluated for technical, environmental and sociopolitical acceptability, long-term liability, resource conservation, and other factors. Specific conclusions are not developed, but research areas are suggested to further define and address environmental problems associated with each option. APPROACH The investigation was developed using current representative designs for incineration and land- filling. A common operating capacity of 100 TPD (tons/day on a wet basis) was selected for each design, and it was assumed that each type of facility was located on-site at a typical chemical plant. The plant setting was assumed to be: (1) the source of a mix of hazardous and nonhazardous wastes; and (2) representative of the upper tier of the chemical industry in terms of size and diversity. The selected designs were characterized in terms of emission controls and other features pertinent to structuring the technical and environmental evaluations. Predictions of environmental emissions from each design were then developed for the selected mix of wastes. Modeling techniques were used to estimate the dispersion of emissions via atmospheric and groundwater pathways, and standards and criteria exceedance assessments were conducted at assumed points of contact from 150 to 1,000 meters away from the sources. SELECTED WASTE MIX The selection of the hypothetical waste mix was done with the objectives of matching waste with technology and of intentionally incurring as many technical environmental impacts as possible to permit demonstration of tradeoffs between the technologies. A waste generation rate of 100 TPD, 260 days per year, was selected as typical of a larger organic chemical production facility. This rate is sufficient to support an onsite landfill and/or incineration system, and the waste mix from such a facility would be expected to consist of smaller amounts of hazardous constituents contaminating larger volumes of nonhazardous wastes. The selection of the waste mix was done in two steps. The criteria at the first level were that the wastes be amenable to both combustion and landfilling in terms of moisture content, volatility, and 261
