This dissertation develops an integrated solid waste management (ISWM) model that extends existing models, allowing economies of scale in waste collection, facility development and operation; multiple landfill operation, landfill closure and replacement, and export of waste; and recycling promotion, modifying consumer’s propensity to recycle, and permitting these policies to be applied in a spatially differentiated way. Initially, it develops an analytical model using optimal control theory for waste management policies. The system operates in a single waste collection area, with one recycling and landfill facility. Waste is either recycled or deposited. The model is solved for different assumptions about cost, including economies of scale. Based on these initial findings, ISWM is formulated as a mixed integer-programming model. The model is calibrated to the Central Ohio Solid Waste Management District and solved under a variety of scenarios. Each model extension is tested and sensitivity analysis is used to determine the impact of changes in disposal capacity, interest rate, and waste generation growth on recycling policy and life. The model is then applied to investigate two issues: First, ISWM model is used to derive an aggregate cost of waste management, as a function of key variables, such as the size of the system, population density, number of facility options, and recycling tastes. Then, the model is run, generating 2,916 observations. The resulting set of pseudo-data is used to regress aggregate cost on the variables. The results confirm empirical findings on economies of scale and density, and suggest the importance of other variables, including facility options and recycling taste. Second, the model is used to derive policy advice for the State of Ohio and the Central Ohio Waste Authority. Model findings suggest that the State-mandated 10-15 year planning horizon for waste authorities should be modified to be longer and/or require a minimum terminal disposal capacity. It also indicates that current recycling levels are close to optimal (based on 30-year planning horizon) but will have to be redoubled within the next five years. Further, the Authority composting subsidies appear to be excessive based on an ISWM-estimated shadow price of landfill capacity.
