Editorial: Geomembranes and water

April 1st, 2018

The World Health Organization (WHO) asserts that a clean water supply is “fundamental to global health.” WHO estimates that considerable exposure worldwide to contraction of many waterborne diseases and conditions (diarrhea, malaria, malnutrition, parasites, bacterial infections, etc.) could be diminished by increasing access to safe drinking water, improving sanitation and hygiene, and improving water management. […]

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 […]

CCR management using geotextile tubes

August 1st, 2017

Introduction Since the late 1800s, coal has played a leading role in U.S. production of electrical energy. Coal-fired power plants have provided reliable electrical power from the earliest days when power plants were run with hand-fed coal to heat boilers to produce steam. The introduction of pulverized coal led to improvements in the electrical-generation process […]

Using geosynthetics for macroencapsulation for CCR on-site clean closure

August 1st, 2017

Coal combustion residuals (CCR) have been used for many years in the construction of berms and engineered structural fill applications, including embankments for highways, dikes, and levees. However, large, unencapsulated structural fill projects have become a focus of environmental concerns due to potential leaching of metals and structural failures. Cap-in-place of CCR surface impoundments is […]

Case Study: Capping semi-liquid solids with geosynthetic layers

October 1st, 2016

Introduction A U.S.-based polyethylene and polyester resin/polymer producer recently closed a manufacturing facility in Wilmington, N.C. (Photo 1). The company hired an engineering firm to manage the demolition and removal of the expansive structures and infrastructure. Part of the environmental responsibilities was to also find a viable solution for closing a 12-acre sludge basin. But […]
