Research Description: Municipalities today are faced with a variety of options on dealing with solid waste. Tools and guidance are needed to make sound decisions, regards to both environmental and economic factors, that takes into account various site specific constraints such as land and water availability, energy costs and needs, and government policies and tax incentives. The goal of this project is to quantify the benefits of various traditional and proposed Waste-to-Energy (WTE) technologies versus landfilling. The results will aid in identification of an optimal process for maximizing profitability while minimizing environmental impact given various scenarios and constraints. The proposed effort leverages previous and current efforts on the demonstration of syngas production from landfill gas and  design and application of selective FTS  catalysts (production of diesel and jet fuel) funded by the Hinkley Center, the Florida Energy Systems Consortium (FESC), and the Department of Energy (DOE).

Scope of work: The five WTE technologies selected for this comparison are gasification or anaerobic digestion to produce electricity, incineration to produce heat and power, or gasification to produce compressed natural gas or liquid hydrocarbon fuels (i.e., diesel). These five technologies will be compared to landfilling and single-stream recycling to reach a total of 7 scenarios. These processes will be evaluated at the system level, such as done by the PIs for various WTE and biomass conversion schemes already, to quantify the key parameters needed for making a sound decision taking into consideration economics and environmental impact. These parameters include CAP-EX, OP-EX, energy input requirements,  GHG emissions, water input requirements, co-product generation and use/market (if any), solid waste production (if any), and profitability. The process simulations will include a sensitivity analysis, which will include a variable production scale, process lifetime, degrees of tax credits, etc. on the eight parameters identified to compare the conversion technologies.
