This review compares whether the multiple recycled and local materials are in use as landfill liners, with fly ash, cement kiln dust, and steel slags appear to be the most viable.
Sustainable waste management requires the development of new landfill liner substances to reduce the environmental risk in terms of the leachate movement and gas emission. In this study, the geotechnical, hydraulic, chemical and environmental characteristics of recycled and locally available material are assessed against the use of fly ash, bottom ash, cement kiln dust, metallurgical slags, sewage sludge, compost, and construction and demolition waste to use as landfill liners. It summarizes results related to hydraulic conductivity, mechanical strength, chemical composition, leaching potential, and environmental safety, resulting in the identification of some promising engineered composites that can comply with the regulatory standards of permeability and strength. Among the major results like fly ash that has been stabilized using either bentonite or lime, cement kiln dust, and steel slags are the promising materials that can be used in landfill liner works whereas the bottom ash, sewage sludge ash as well as the organic wastes are revealed to be potentially useful under proper guidance. To balance the scale between high performance engineering and conservation of the environment, this review supports the need for site-specific evaluation, quality control requirements, and long-term monitoring. Overall, this project eases this sustainable landfill process through the incorporation of supporting the integration and use of valorized recycled waste materials and the reduction of acquired raw materials in addition to enhancing the guidelines and security of landfill liners.
Mr. Emon is an environmental and social safeguard specialist with 23+ years of experience. Currently pursuing a PhD in Environmental Engineering focusing on sustainable waste management.
