Hybrid geosynthetic clay liners for attenuation of PFAS in landfill leachates

October 1st, 2021

An exponential increase in understanding of the provenance, migration, and fate of per- and polyfluoroalkyl substances (PFAS) is evident over the past decade. The environmental and health concerns from this group of contaminants are well recognized, but they are still evolving with advancing studies. A key property of PFAS compounds at a molecular level is […]

The many applications for geosynthetics in the energy sector

October 1st, 2018

The opportunities for geosynthetics in energy applications are nearly endless. There are huge energy categories, such as oil, natural gas and coal, but geosynthetics also play a role in nuclear energy, hydropower, wind power and solar power, among others. Geosynthetics line storage tanks, support roads to remote sites, line tailings ponds, provide filtration, dewater coal […]

Multilinear drainage geocomposites to filter oil sands tailing slurries

October 1st, 2018

Mining and some energy operations generate large quantities of water-containing tailings. These tailings are made of crushed-rock particles that are deposited in a slurry form. This is the case for coal, tar sand, lead, zinc, gold, silver, copper, molybdenum, nickel, taconite (iron), phosphate, bauxite (aluminum oxide), uranium, trona (soda ash) and potash, for example. There […]
