Geosynthetics for CCR, PFAS and energy applications

October 1st, 2021

This issue of Geosynthetics magazine delves deep into two innovative uses of geosynthetic clay liners (GCLs) in very different applications: coal combustion residual (CCR) leachates and per- and polyfluoroalkyl substances (PFAS) mitigation in landfills. We also examine three case studies of energy companies using high-density polyethylene (HDPE) geomembranes for flowback water in water evaporation/recycling ponds. […]

Using bentonite-polymer composite geosynthetic clay liners to contain CCR leachates

October 1st, 2021

FIGURE 1 To tackle tough leachates and shield the environment from hazardous byproducts created by a coal ash site such as this, a GCL is being installed for advanced protection. (Photograph courtesy of CETCO) Coal combustion residuals (CCRs) are the byproducts from combustion in coal-fired boilers that are disposed in lined landfills when they cannot […]
