  • Abstract:
  • Sanitary landfills play a critical role in managing municipal solid waste, ensuring environmental protection and public health and require effective liner systems to prevent the contamination of surrounding soil and groundwater. Among the essential components of a sanitary landfill system are liners, which prevent leachate migration into the surrounding environment. Clay minerals have long been considered effective materials for liners due to their low permeability and abundance. The effectiveness of clay liners in preventing leachate migration and groundwater contamination is crucial for the environmental sustainability of landfills. Various clay minerals, including pond clay, kaolinite, Normal loam soil, and bentonite, were evaluated for their hydraulic conductivity, cation exchange capacity (CEC), swelling properties, and chemical compatibility with landfill leachate. Results indicate that bentonite, with its high swelling capacity and low hydraulic conductivity, offers the most promising performance as a landfill liner material. However, considerations such as availability, cost, and environmental impact should also be taken into account when selecting the appropriate clay mineral for landfill liner applications. The efficacy of clay minerals as liners in sanitary landfills is paramount for preventing the leaching of contaminants into the surrounding environment. The study examines the physical, chemical, and mechanical properties of different clay minerals, their interactions with contaminants in landfill leachate, and their long-term stability. Furthermore, the report discusses the suitability of specific clay minerals for different landfill conditions and provides recommendations for optimizing liner design and performance. It also tries to evaluate the performance of various clay minerals as liners in sanitary landfills through a comprehensive review of literature and experimental data and comprehensively evaluate the performance of various clay minerals, ensuring the selection of the most effective and environmentally sustainable option. Through a combination of laboratory experiments and computational techniques.
