Use of Geosynthetics for Sustainable Landfill Design and Leachate Control

Abstract

The safe disposal of municipal solid waste has become a critical aspect of sustainable environmental management. Traditional landfill designs often result in groundwater pollution, structural instability, and uncontrolled gas emissions. Geosynthetics—synthetic polymeric materials engineered for geotechnical applications—have emerged as a reliable solution to these challenges. Their integration into landfill systems enhances structural integrity, prevents leachate migration, supports gas collection, and minimizes environmental footprints. This paper explores the types, functions, and performance of geosynthetics in modern landfill engineering. It also discusses their role in effective leachate control and long-term environmental sustainability. Case studies and comparative evaluations illustrate how geosynthetic-based systems outperform conventional methods, offering both ecological and economic advantages.
