Techno-Economic Optimization Of Food Waste Diversion To Treatment Facilities To Determine Cost Effectiveness Of Policy Incentives, Kanwal Shahid
Techno-Economic Optimization Of Food Waste Diversion To Treatment Facilities To Determine Cost Effectiveness Of Policy Incentives, Kanwal Shahid
Theses
New York state recently passed a food waste (FW) disposal ban, which will prohibit land-filling of FW produced by commercial entities generating more than 2 tons/week by the year 2022. This will redirect 370,000 tons/year of FW from landfills. In this work, we investigate three questions about the landfill ban: 1) How can this waste be diverted to treatment facilities at lowest system cost? 2) To what degree can an expanded anaerobic digestion portfolio help with the state’s Renewable Portfolio Standards? 3) What policies can help with the transition of waste-to-energy technologies? We develop a mixed-integer linear programming model that …

Application Of Biochar As An Additive To Enhance Biomethane Potential In Anaerobic Digestion, Cecilia B. Frias Flores
Theses
Energy and useful materials can be produced by applying biological and thermal conversion processes such as anaerobic digestion and pyrolysis. Agricultural and industrial wastes seem to be the most attractive substrates since they are essentially unlimited resources. Pyrolysis has been used mostly for the conversion of biomass to bio-crude and biochar, a stable form of nearly pure carbon that has application in many agricultural and environmental applications. There is a widespread literature describing use of biochar as an additive to stabilize the anaerobic digestion process. We studied the effects that biochar has on the biomethane potential (BMP) during anaerobic digestion …
