Workshop: Waste Management Challenges

State of the Art Solid Waste Management Modeling (3.5 CEUs)

Thursday, September 28, 2017
8:30 – 12:00
Room 306

Proper management of solid waste is essential to minimize risks to human health and the environment. Solid waste management (SWM) is a highly visible and potentially high-impact target for enhancing environmental sustainability. However, there are numerous competing alternatives for increasing environmental sustainability such as recycling, energy recovery, and organics treatment. These potential alternatives must be systematically evaluated to ensure that SWM strategies cost-effectively protect human health and the environment. Life-cycle assessment (LCA) provides the necessary systematic framework for estimating the environmental impacts associated with alternative SWM processes and systems. Life-cycle process models that estimate emissions and resource use from solid waste unit processes (e.g., collection, composting, landfills) form the foundation of SWM LCAs.

This half-day workshop will cover the state-of-the-art for modeling solid waste processes and identify key research needs and areas for potential improvement. Each speaker will present the state-of-the-art for a given process, which will be followed by time for questions, comments and discussion. Topics include modeling of waste-to-energy combustion, composting, anaerobic digestion, landfills and uncertainty management. This workshop will build on insights gained from a similar LCA Workshop developed by Anders Damgaard and James Levis for the 2016 ISWA World Congress, and it will be updated for the 2017 World Congress & WASTECON® audience with a focus on practical applications.


Dr. James Levis, Research Assistant Professor, North Carolina State University

James Levis

Dr. James W. Levis is a research assistant professor in the Department of Civil, Construction and Environmental Engineering at North Carolina State University. He received a Bachelor’s degree in mechanical engineering from Carnegie Mellon University and a Master’s degree and Ph.D. in civil engineering from North Carolina State University. Since 2006, he has conducted research on the development and use of novel life-cycle, simulation and optimization models for environmental policy and decision support—with a primary focus on integrated waste management, energy systems and sustainable infrastructure. Dr. Levis is the author of more than 15 peer-reviewed publications and has made more than 30 presentations at conferences and workshops.

Dr. Morton Barlaz, Distinguished University Professor, North Carolina State University

Morton Barlaz

Dr. Morton A. Barlaz is a Professor in the Department of Civil, Construction, and Environmental Engineering at North Carolina State University. He received a B.S. in Chemical Engineering from the University of Michigan and an M.S. and Ph.D. in Civil and Environmental Engineering from the University of Wisconsin. He has been involved in research on various aspects of solid waste since 1983. Over this time, he has conducted research on refuse decomposition, methane production, and the degradation of hazardous wastes in landfills. Dr. Barlaz also conducts research on the use of life-cycle analysis to evaluate environmental emissions associated with alternate solid waste management strategies. Dr. Barlaz is the author of over 60 peer-reviewed publications and has made over 100 presentations at conferences throughout the world. He is an Associate Editor for two journals (Waste Management and Journal of Environmental Engineering) and co-chair of the Intercontinental Landfill Research Symposium. In 1992 he was awarded a Presidential Faculty Fellowship from the National Science Foundation.
