Landfilling is considered the most common method for solid waste disposal and treatment. Landfilling method has the advantages of low cost and effectiveness, as well as simplicity; however, this disposal method needs to be managed properly in order to prevent and mitigate environmental contamination. Landfilling causes the generation of leachate which is a regularly expected phenomenon in all landfills. Leachate is considered very contaminated wastewater that consists of mixtures of toxic inorganic and organic pollutants and high concentrations of natural organic matter. Hence, the characterization of leachate is an important step toward preventing environmental pollution and assessing the efficiency of leachate treatment facilities. Moreover, it is of significant importance to discuss and understand the collection and recirculation systems used to manage the generated leachate from different landfills. Therefore, this chapter will introduce and summarize different topics related to landfill leachate generation, including leachate generation modeling, leachate collection systems, leachate characterization and quality, and leachate recirculation systems. Finally, the operational issues that could face leachate collection systems and their management strategies are further discussed.
