Editorial: Geosynthetics for multiple applications
October 1st, 2017
If you are reading this publication, you obviously have an interest in geosynthetics, as this magazine is unlikely to appeal to people whose primary professional interests are taxidermy, snow-crystal study or calligraphy. We aim to please, and this issue touches on many types of geosynthetics, from geogrids to geomembranes, and many applications of geosynthetics, from […]
Part 2: The regulation of CCR in the United States: Geosynthetics and barriers
October 1st, 2017
As discussed in Part 1 of “The Regulation of CCR in the United States,” for the first time in decades, nationwide regulation of CCR (coal combustion residuals) surface impoundments expands the regulated use of geosynthetic materials. While the CCR Rule (2015) allows continued operation of existing CCR surface impoundments, it provides criteria for the disposition […]

Editorial: The management of coal combustion residuals (CCR)
August 1st, 2017
The management of coal combustion residuals (CCR or “coal ash”) is a growth category for the geosynthetics industry. Multiple opportunities now exist using various types of geosynthetics due to the evolving federal and state regulations for handling CCR. In fact, geosynthetics have played a role in the regulations that have developed. “These regulations have been […]
