GSI to host webinar on disposal of CCR this Wednesday, GMA members get discounted rates

October 22nd, 2018 / By: / GSI News, Industry News, Resources

The Geosynthetic Institute (GSI) will sponsor a webinar entitled “Disposal of Coal Combustion Residuals,” on Oct. 24, from 11:30 a.m. to 1 p.m. EDT. The webinar will be hosted by Dr. Robert M. Koerner. 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 (CCR) 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 will describe the status today including detailed stability analyses of several sites. It also mentions that there are more than 600 such facilities in the U.S. along with their approximate geographic locations. The webinar then will address, in detail, various geosynthetic related opportunities with disposal sites.

All methodologies are within the state-of-the-practice of geosynthetic engineering design and construction but are largely unknown or underutilized in CCR disposal. Each of the nine scenarios will be 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 CCR. 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. Considering 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.

This webinar will be beneficial 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; 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. 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 Geosynthetic Materials Association (GMA) members, and $250.00 for nonmembers. Successful completion of a multiple-choice test after the webinar carries 1.5 professional development hours (PDH).
