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. […]

Energy industries use HDPE liners for flowback water evaporation/recycling ponds

October 1st, 2021

FIGURE 1 To increase evaporation with low costs in mind, a “weep” system was added at Danish Flats to allow water to flow and fan out over the surface of the HDPE liner that is above the waterline. The problem to be solved is the disposal and recycling of millions of gallons of production water […]

Solmax pit thermal energy storage with geosynthetics on the Tibetan Plateau

July 19th, 2021

Photograph courtesy of Solmax Tibet has an average elevation of more than 13,100 feet (4,000 m), reaching to 16,400 feet (5,000 m). At these heights, temperatures can remain below freezing all day in winter, plunging to –4°F (–20 °C). In 2018, Tibet’s first large solar thermal district heating system was designed and built at 15,000 […]

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 […]

Case studies using EPS geofoam for mining and energy

August 1st, 2018

The complexities of the built environment continually challenge the limits of engineering and construction. For infrastructure built-in areas with settlement-prone soils or other hazardous geological conditions, assembling a team of experts to plan for challenges is essential. Industries like mining, oil and gas, and utilities must often bore through earth and rock to build tunnels, […]
