Co-Disposal in MSW Landfills: Liquid, Solid and High-Moisture Wastes
June 5, 2:00 – 3:30 pm EST

This webinar is designed to provide (i) an overview of co-disposal in MSW landfills, (ii) recent findings from a laboratory study on co-disposal and (iii) motivation and objectives pertaining to a new EREF-funded project on co-disposal of high-moisture content wastes.  The first part of the webinar will be given by EREF where they will share findings from a recently completed study entitled “Disposal of Aqueous Wastes in MSW Landfills – Utilization and Effectiveness of Bulking and Stabilization Strategies.”  The second part of the webinar will include an overview and summary of a laboratory study completed for the EREF-funded project entitled “Implications of Solid and Liquid Waste Co-Disposal on Organic Stability and Biochemical Compatibility.”  Finally, the third part of the webinar will include an overview of the motivation and objectives pertaining to a new EREF-funded project entitled “Evaluation and Management of High-Moisture Waste Disposal in Municipal Solid Waste Landfills.”


Attendees of this webinar should anticipate learning the following:

  • State-of-the-practice of liquid co-disposed in MSW landfills
  • Aqueous wastes accepted by landfills and relevant bulking or stabilization agents
  • Observations from laboratory reactors regarding the impacts of co-disposal on biodegradation and biochemical compatibility
  • Impact of high moisture wastes on hydraulic conductivity and shear strength of MSW
  • Future research efforts supported by EREF to target challenges related to co-disposal of high-moisture wastes in MSW landfills

Christopher Bareither, Ph.D., P.E.
Associate Professor
Colorado State University

Dr. Bareither is an Associate Professor in the Department of Civil and Environmental Engineering at Colorado State University (CSU) where he conducts research and teaches in the field of Geotechnical and Geoenvironmental Engineering.  His research focuses on mechanical properties of geomaterials, physical, hydraulic, chemical, and biological behavior of solid waste, and mining geotechnics and mine waste management.  He currently serves as faculty advisor to the CSU chapter of Engineers Without Borders and is a licensed Professional Engineer in Colorado. Dr. Bareither received a BS in Geological Engineering from the University of Idaho (2004) and an MS and Ph.D. in Geological Engineering from University of Wisconsin-Madison (2006 and 2010).Bryan Staley, P.E., Ph.D.
President and CEO
Environmental Research & Education Foundation (EREF)

Dr. Bryan Staley currently serves as President and CEO of the Environmental Research & Education Foundation (EREF), one of the largest sources of research funding and graduate scholarships related to solid waste management. He joined EREF in 2008, where he started as Vice President of Environmental Programs, and has over 20 years’ experience in the environmental engineering field.

He is recognized nationally as a technical expert in sustainable solid waste management issues, and obtained a Ph.D. in Civil Engineering from North Carolina State University, where his research focused on understanding microbiological mechanisms for waste decomposition and methane generation from solid waste. He also holds a Master’s degree in Biosystems Engineering from the University of Tennessee, and a B.S. in Biological & Agricultural Engineering from North Carolina State University.

Dr. Staley is a licensed professional engineer who has held key positions in consulting firms as a Project Manager and Vice President of Engineering, where he managed projects ranging from solid waste management, wastewater treatment system design, to retail/commercial land development and environmental management of large-scale livestock operations.

Brush Up Before the Webinar!

EREF’s 2018 report, Utilization and Effectiveness of Waste Bulking and Stabilization Strategies, identifies the types of aqueous waste materials accepted by landfills that require stabilization, documents the materials typically used as bulking or solidification/stabilization (S/S) agents, describes the material testing, considerations and challenges when selecting agents and summarizes the properties and reactivity of bulking and S/S agents, such as potential for heat generation or metals leaching.
