PVC geomembrane specifications for South American lithium mining
June 1st, 2022
FIGURE 1 A covered pond with a PVC geomembrane (left) that complies with Fabricated Geomembrane Institute (FGI) specifications. A second pond (right) is already filled with lithium brine. Lithium, one of the raw materials in various batteries, is the element powering the technological revolution over the past 30 years that has led to people having […]
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. […]
