Zoom Webinars
Please see session descriptions, speaker information and registration links below.

SWANA FL, the Hinkley Center, and Autocar invite you to join a few innovators who are developing the future of Solid Waste Management – in Florida and around the world. The 2020 Hinkley Center Solid Waste Research Colloquium Webinar Series brings to you cutting edge research in solid waste including:

  • The future of measuring the benefits of recycling
  • The management of leachate using constructed wetlands
  • The conversion of landfill gas to useable energy
  • The application of materials to treat landfill emissions

The researchers will present their current work and provide a glimpse of emerging concepts in your future solid waste operations.

There will be a total of four unique webinars in this FREE series – October 13th, 14th, 20th and 21st. Make plans to join us for as many as you would like. Please register for each webinar separately. Scroll down for the registrations links and a description of each presenter and their topic.

Continuing Education

Participants can earn CEUs toward their SWANA recertification and State of Florida continuing education requirements for operators by attending the webinars. Refer to the individual webinars below for details. Professional Engineers will have the opportunity to earn continuing education course hours. Please email after the completion of the webinar series for necessary documentation.

October 13 – 12PM to 1:30PM

Research Topic: An Integrated Tool for Local Government to Track Materials Management and Progress Toward Sustainability Goals

Professor Townsend will discuss efforts to develop a tool for Florida regulators, local governments and the waste management community that will allow recycling rates and sustainable materials management metrics to be integrated.

Dr. Timothy Townsend, University of Florida

Timothy Townsend is a Professor in the Department of Environmental Engineering Sciences in the Engineering School for Sustainable Infrastructure and the Environment at the University of Florida.  Dr. Townsend teaches and conducts research related to solid and hazardous waste management.  His courses cover subjects such as waste management fundamentals, landfill design, recycling, construction and demolition debris, and waste management in developing countries.  He has published many papers and research reports on topics related to bioreactor landfills, recycling, construction and demolition debris, waste leaching, beneficial use of solid wastes, and special wastes such as electronic scrap.  His recent book is titled Sustainable Practices for Landfill Design and Operation.



October 14 – 12PM to 1:30PM

Research Topic: Cost-Effective Hybrid Constructed Wetlands for Landfill Leachate Reclamation

Dr. Ergas will speak on her Hinkley Center funded project that investigates amending constructed wetland (CW) media with low cost adsorbents, zeolite, and biochar.  These materials adsorb ammonia and recalcitrant organic compounds, reducing their toxicity to microbes and enhancing biological degradation.  In side-by-side bench scale studies, bioreactors with zeolite and biochar achieved significantly higher removal of chemical oxygen demand (COD), color and ammonia removal than unamended control.   Pilot scale hybrid CW systems with and without adsorbent addition are currently being operated at a landfill in Florida.

Dr. Sarina Ergas, University of South Florida

Dr. Sarina Ergas is a Professor and Graduate Program Director in the Department of Civil & Environmental Engineering at the University of South Florida, Tampa.  She holds a BS in Environmental Engineering from Humboldt State University and MS and PhD degrees in from the University of California, Davis.  Her research focuses on environmental biological processes, including biological nutrient removal and waste-to-energy technologies.  She is a fellow of the Association of Environmental Engineering and Science Professors (AEESP) and the Water Environment Federation (WEF).  She is a licensed Professional Engineer and an AAEES Board Certified Environmental Engineer.


October 20 – 12PM to 1:30PM

Research Topic: Compatibility Testing of Polymer-Modified Bentonite GCLs

Dr. Abichou will report on recent research, funded by the Hinkley Center, on the use of geosynthetic clay liners (GCLs) in landfill lining systems. In particular, he will present summaries of their findings on the long-term hydraulic conductivity of polymer-modified bentonite GCLs with MSW-I ash leachates as well as the factors influencing polymer elution and the mechanisms controlling chemical compatibility of a polymer-modified bentonite GCL containing linear polymers. The presentation will then conclude with new recommendations on assessing the compatibility testing of polymer-modified bentonite GCLs.

Dr. Tarek Abichou, Florida State University

Dr. Abichou is a Professor of Civil and Environmental Engineering, at Florida State University. Dr. Abichou received his MS and PhD form the University of Wisconsin in Madison. He is known for his research investigating the mitigation of greenhouse gas emissions from landfills using bio-oxidation of methane using Biocells, Biocovers, and Biofilters. His research group developed a model to inventory fugitive emissions from landfills. He also has an extensive experience in temporal and spatial characterization of methane emissions from landfills using static flux chambers, optical remote sensing, and tracer techniques.


October 21 – 12PM to 1:30PM

Research Topic: Methods to Upgrade Landfill Gas to Fuel and Chemicals

Landfill gas has long been a by-product of landfill decomposition that has historically been managed by just flaring off the gas. Over the last several decades many projects have been developed to utilize the gas to produce electricity or to process it into a direct use or compressed natural gas for industry or vehicles. Dr. Kuhn will be presenting his team’s research into innovative methods of converting and upgrading landfill gas to other forms of useable fuel and chemicals, not currently being done, that can be utilized for operations or sold in the marketplace.

About the Hinkley Center for Solid and Hazardous Waste Management

The Hinkley Center for Solid and Hazardous Waste Management is a statewide center that provides leadership in waste management research with the goal of preserving and protecting the state’s natural resources. The research program focuses on methods and strategies for managing solid and hazardous wastes. Research results are transferred to the public and private sectors for practical applications. Principal research areas include Construction & Demolition Debris, Electronic Waste, Hazardous Waste Management, Incineration, Landfills, Medical Waste Management, Municipal Solid Waste Management, Pollution Prevention, Recycling and Reuse, Socioeconomic Issues, Special Wastes, and Waste Reduction.

A little bit about Bill:

Bill Hinkley used to work in a boat yard in South Florida, scraping barnacles off the bottoms of boats. After he grew tired of scraping barnacles, he applied for a water quality sampling job at the Florida Department of Environmental Responsibility (DER) in their South Florida District Office. He rose through the ranks of the DER and served as Special Assistant to the Secretary of the DER who then transferred Bill into the Solid Waste Department. When Senator Kirkpatrick started on his solid waste bill in the 1980s, he met Bill Hinkley and immediately saw that Bill was a talented and sociable person. Senator Kirkpatrick recruited Bill to help him draft the 1988 Solid Waste Act, which ultimately changed the course of solid waste management in Florida.

Bill was also a proponent of conducting research on an issue before starting rule making. He was a huge supporter of the then Florida Center for Solid and Hazardous Waste Management. He loved his family very much and the small beach cottage that his family built on Saint George Island called “Island Baby”. He built his own house on a land cooperative east of Tallahassee called the Micanopy Land Cooperative, a collection of five-acre lots with homes of a wide variety of designs. He loved to sail and meet people.

When Senator Kirkpatrick’s legislative aide, Mike Murtha, learned that Bill had been diagnosed with a form of cancer that is always fatal, Mike immediately drafted a bill to change the name of the Center to honor Mr. Bill Hinkley. Bill learned of this shortly before his death and said that he was very humbled by the Legislature’s action. When Bill was asked about what he wanted in terms of a service after his death, he said that he wanted a lot of people enjoying music, dancing, food, wine, beer, fireworks and having a lot of fun. We hope that the Colloquium will stay true to the spirit of innovation and fun that defined Bill Hinkley.
