The Geosynthetic Institute had a particularly busy 2018 with White Papers, issuing five of them. All of them are worth reading. One that particularly caught our eye, however, was...

In the February 2013 issue of Plastics Technology, senior editor Lilli Manolis Sherman reports that commodity resin prices have shot up for a number of reasons: unplanned disruptions in polymer feedstock production in December, planned cracker outages slated for the first four months of this year, etc. Monomer and resin prices have risen, especially with regards to polypropylene. Polyethylene and PVC have also been affected. Some geosynthetics manufacturers have acknowledged these price shocks too in having to increase prices on products as well. Learn more here.;

CETCO has announced the next session of GCL University, an on-going series of comprehensive training seminars for engineers, regulatory personnel and facility owners/operators. This next session will be held in Pocatello, Idaho on February 12 and focus on "Design and Construction with Geosynthetics in Mining Cover Systems." Practical applications and engineering principles will be the focus. The seminar is free of charge. Those in attendance will be eligible for 5 hours of pdh credit. SPEAKERS INCLUDE Craig H. Benson (University of Wisconsin-Madison), Greg Corcoran (Geosyntec Consultants), an agency representative from the Idaho Department of Environmental Quality, Monte Christie (Geo-Logic Associates, Inc.), and David Andrews and Greg Groene (TRC Solutions, Inc.).

The Fabricated Geomembrane Institute (FGI) has announced a 28 February 2013 short course on "Environmental Protection in Shale Oil and Gas Development."
