of geosynthetics, in strong
cooperation with IGS, via:
»	 Organization of and
participation in technical
conferences, seminars
and workshops
»	 Development and
dissemination of tools for
geosynthetics education

IGS-NA supports Tailings and Mine
Waste 2020 conference

T

ailings and Mine Waste 2020 went virtual this year and drew a huge crowd to its sessions.
The North American Chapter of the International Geosynthetics Society (IGS-NA) is
proud to be a supporting organization of this annual event that alternates between Keystone,
Colo., Banff, Alb., Canada, and Vancouver, B.C., Canada. The geosynthetics session was hosted
by IGS-NA board members Kate Patterson and John Allen, who also serve on the conference
organizing committee. There were 190 attendees in the geosynthetics session, which featured
papers by Anna Norris who is finishing her Ph.D. at Colorado State University, where she is
investigating geosynthetic clay liner permeability with tailings solutions and pregnant copper
and gold solutions. Pascal Saunier, P.E., shared his research on a new drainage geocomposite for
dewatering tailings. Dr. Mike Donovan presented his work on lighter and longer geosynthetic
clay liners for use in mining applications. While polymers are the backbone of the geosynthetics
industry, we continue to see new and innovative uses within these papers and the incorporation
of new polymers. Dr. Raymond Guang shared his work on how to transfer the use of polyacrylamide polymers from dewatering tailings and apply it to the dewatering of dredge materials.
On behalf of the moderators, organizing committee and IGS-North America, we would like
to thank all our authors and speakers for contributing to a very successful Tailings and Mine
Waste 2020 conference. G
