Evaluating the Performance of Modified Geo-Synthetic Clay Liners

Waste products from human activity must always be controlled. Reusing some garbage is possible. But a lot of rubbish that could be more useful needs to be disposed of to protect the environment. Landfilling is one popular form of disposal. The most frequent issues with landfills are groundwater contamination and environmental deterioration, brought on by rainfall and leachate generated during the breakdown of organic materials. A landfill's liner is crucial to stop leachate migration and groundwater contamination. Since their development in 1986, Geo-Synthetic Clay Liners (GCLs) have gained popularity as a barrier solution for municipal solid waste landfills. In this study, fly ash and Kaolinite, two waste materials, are combined with bentonite in different percentages 10–30% and 50%, respectively to evaluate their potential usage as liner materials. Bentonite, in combination, is anticipated to function as a low permeability, self-healing, hydraulic barrier due to these swelling qualities.
