A Preliminary Sustainability Analysis Of Producing Class A Biosolids With Conventional And Low-Cost, Low-Tech Processes, Janna Brown
Dissertations, Master's Theses and Master's Reports
Producing Class A biosolids is a beneficial way to reuse wastewater sludge. Low-cost, low-tech (LCLT) processes are attractive to small water resource recovery facilities (WRRF) because of their low capital costs and simple designs. This study examined the sustainability of conventional and LCLT processes at small WRRFs. The environmental impacts were determined by conducting life cycle assessments. Cost analyses determined the economic impacts. The social impacts were analyzed by investigating case studies and surveys of social response to biosolids. The environmental, economic, and social impacts were normalized, and each technology received an overall score. The technologies studied were direct heat …
Application Of Agent-Based Modeling To Complex Systems, Robert J. Zupko Ii
Application Of Agent-Based Modeling To Complex Systems, Robert J. Zupko Ii
Dissertations, Master's Theses and Master's Reports
This dissertation examines the application of agent-based modeling (ABM) to complex systems with the intent of developing a means of overcoming limitations present in existing tools. This is done though the development of two ABMs intended to address complex systems present in the fields of sustainability studies and chemistry.
After introductory information, Chapters 2 - 4 of this dissertation address the limitations of tools intended to project the environmental, economic, and social impacts of woody biomass based biofuels. Chapter 2 begins by discussing the limitations in tools to study timber harvest decision making and its impact upon the landscape, and …
