NettetLANDFILL CAPS AND CLOSURES Geosynthetic clay liners (GCLs) are used either as a sole hydraulic barrier or as part of a composite lining system in combination with a geomembrane (Figure 2). The function is to inhibit the flow of precipitation into the landfill as well as to prevent the escape of any gasses into the environment. A landfill liner, or composite liner, is intended to be a low permeable barrier, which is laid down under engineered landfill sites. Until it deteriorates, the liner retards migration of leachate, and its toxic constituents, into underlying aquifers or nearby rivers, causing potentially irreversible contamination of the local … Se mer There are certain levels of harmfulness in which the different types of trash have; therefore, there are different types of liner systems which are required for these different types of disposal sites.
