COMANCO completes final geosynthetics layer at Trail Ridge Landfill
February 7th, 2023
COMANCO has completed the sixth and final layer of its geosynthetics (primary geocomposite layer) and leachate collection system at the Trail Ridge Landfill in Jacksonville, Fla., a project that broke ground in 2022. Because the 30-acre containment site needed a six-layer geosynthetic system, the crew used 180 acres of material to finish the expansion. The […]
Design of reinforcement geosynthetics in landfill piggyback expansion
June 1st, 2021
FIGURE 1 Installation of reinforcement geosynthetic An operator at a nonhazardous waste storage facility proposed extending the facility’s life, within the existing perimeter, by vertically expanding the cells in operation to a maximum thickness of waste of 52.5 feet (16 m). This project is based on nonhazardous waste storage cells 49.2-feet (15-m) thick, some of […]
Part 2: The regulation of CCR in the United States: Geosynthetics and barriers
October 1st, 2017
As discussed in Part 1 of “The Regulation of CCR in the United States,” for the first time in decades, nationwide regulation of CCR (coal combustion residuals) surface impoundments expands the regulated use of geosynthetic materials. While the CCR Rule (2015) allows continued operation of existing CCR surface impoundments, it provides criteria for the disposition […]
Part 1: The regulation of CCR in the United States: Geosynthetics and barriers
August 1st, 2017
The regulation of coal ash (coal combustion residuals or CCR) has significantly expanded the market for geosynthetics within the United States. Further, there is interest in these regulations around the globe in every country using coal as an energy source. These regulations are the result of recent environmental incidents. The regulations call for the increased […]
