Why are GCLs often used for liners in landfills?
July 21st, 2023
Ongoing management of landfill sites involves complex environmental challenges and requires strict compliance with certain guidelines. Managing issues such as leachate, runoff, gases, and other by-products of the waste management process have traditionally been managed by lining and capping cells with clay. Geosynthetic Clay Liners (GCLs), however, offer an alternative to traditional clay lining of landfill […]
