Role of Clay Liners in Municipal Solid Waste Landfills: A Review
Abstract: Rapid population growth has significantly increased the generation of municipal solid waste (MSW) in urban and suburban regions. Disposal of MSW in landfills without proper liner systems may lead to leachate migration and subsequent contamination of groundwater and surrounding soils. The use of liner systems at the base of landfills is therefore essential to minimize leachate percolation and protect the environment. Geosynthetic clay liners (GCLs) and compacted clay liners (CCLs) …
