Description
Summary:Waste disposal in landfills has gained momentum in the last few decades as it is one among the easy and cost-effective method for waste management for the accelerating global population. Heterogenous nature of the waste ending up in landfills makes it difficult to predict the fate of these pollutants making it difficult for its biomonitoring and specific treatment. Among the major issues associated with landfill treatment, liquid percolation from this heterogenous waste substrate collectively referred as leachate poses the greater risk to environment through soil and ground water pollution. The diversity of micropollutants presents in landfill leachates ranging from microbial pathogens, pesticides, microplastics, pharmaceuticals and other harmful chemicals calls for crucial attention towards improving methods used for their treatment and removal. This review summarizes the key components of landfill leachates with specific emphasize on micropollutant content of leachate. Further the features of most recent and advanced technologies that were successfully explored for micropollutant removal from landfill leachates are presented in this review. [Display omitted] •Characteristics and composition of landfill leachate have been reviewed.•Major micropollutants in the landfill leachate were described.•A critical analysis of updated advanced technologies was performed.•Future strategies on management fate and management of the landfill leachate are addressed.
