GSI to host webinar on disposal of coal combustion residuals

Events | October 30, 2019 | By:

The Geosynthetic Institute (GSI) will sponsor a webinar, “Disposal of Coal Combustion Residuals,” on Nov. 13, from 11:30 a.m. to 1 p.m. EST. Geosynthetic Materials Association (GMA) member companies and their employees receive discounted rates on all GSI webinar and short course registrations.

With coal representing more than 25% of energy sources, the disposal of coal combustion residuals is critical. They are placed in disposal areas either in a dry or wet state. The latter is by slurring behind earthen embankments and several have failed in recent years, e.g., in Spain, Hungary and the U.S. (one in North Carolina, the other in Tennessee). This webinar describes the current status including the detailed stability analysis of several sites. It also mentions that there are more than six hundred such facilities in the U.S. along with their approximate geographic locations.

The webinar then addresses, in detail, various geosynthetic related opportunities with disposal sites. All the methodologies are within the state-of-the-practice of geosynthetic engineering design and construction but are largely unknown or underutilized in the context of CCR disposal. Each of the nine scenarios is rather detailed and complete such that the webinar participant will be knowledgeably informed of their present status.

Participants will gain detailed perspectives on the status of both dry and wet disposal of coal combustion residuals (CCRs). This includes amounts, types, locations and general design scenarios of the containment embankments. Detailed analyses of such embankments with several case history failures are presented. In light of this background, nine geosynthetic solutions involved in proper disposal will be detailed and illustrated. Ultimately, each participant of the webinar will become knowledgeable of the opportunities and practices that currently exist.

The webinar is intended for public and private owners/operators of landfills, heap leach pads, shale gas cuttings, combustion coal residuals and related solid waste facilities; consultants and designers in the public and private sector; regulators and agency personnel at the federal, state and local levels; geosynthetic manufacturers and their representatives; geotechnical and geosynthetic testing organization personnel; contractors and installers of liner and cover systems; academic and research groups; and others desiring technically related information on this important aspect of our constructed environment.

The webinar’s instructor, Dr. Robert M. Koerner, is professor emeritus of civil engineering at Drexel University, and founder and director emeritus of the Geosynthetic Institute.

Webinars cost $200.00 for GSI and GMA members, and $250.00 for nonmembers. Successful completion of a multiple-choice test after the webinar carries 1.5 professional development hours (PDH).
