The use of liners as leachate retainers in landfills, which is the final stage of waste processing, has become a global trend. Recently, researchers of the materials used as retainers have aimed to find the best materials while minimizing losses from landfills. As such, in this study, we conducted a comprehensive review to determine trends, evolutions, key research areas, and future research paths in this field. Our findings serve as a reference for advancing progress in landfill liner research. We used bibliometric and content analyses of the field in the literature from 2011 to 2021. We analyzed a total of 385 articles from the Scopus database using the Vos Viewer application. We concluded that this topic has received considerable in the 10-year period. From the 142 keywords and 5 clusters we obtained, we found that the most attention was paid to geosynthetic and geomembrane materials. We provide several recommendations that can be addressed in future research.
