DescriptionWaste-to-energy (WTE) facilities demonstrate great potential in making maximal use of the increasing amount of waste in modern society. While current researches focus on a certain technology or specific aspects of the technology (e.g.(Bernstad and la Cour Jansen 2011) on life cycle analysis for household food waste; DEFRA (2007) for modern waste incineration in Europe; Whyte et al. (2001) for cost analysis using anaerobic digestion technology; among many more), this study has developed an broader framework to compare the electricity generation capacity, as well as economic benefits and costs of alternative WTE technologies. In the end, we use food waste and manure generation data from New Jersey and apply this integrated program to analyze four theoretical scenarios: Direct Combustion, Landfill-to-Gas, Composting and Anaerobic Digestion. When calculating productivity, we estimated methane yields and corresponding green electricity generation using a simulation program in Matlab. The results indicate that anaerobic digester with gas collection facilities can generate the largest amount of methane and green electricity generation per unit of waste. In total, WTE facilities can supply hundreds to thousands of local households with green electricity. In the economic analysis, landfill-to-gas method is proven as the least costly method to consume a unit of waste and has the highest net revenue income stream. In comparison, direct combustion is by far the most costly method. In summary, composting and landfill-to-gas are the two favorable methods of treating food waste and manure on a large scale. From the aspect of land scarcity and carbon footprint reduction, anaerobic digestion still has great potential to benefit New Jersey municipalities. While discussing the limitations of the simulation analysis, we lay a foundation for further study. Regulatory recommendations are also provided to decision makers in waste management facilities.
