New Emerging pollutants (NEPs) are substances that have recently occurred widely in the environment and recognised as a possible environmental or public health risk. In the new era, even with the new evolving technologies, NEPs still exists, which merit appropriate control. However, there is no sufficient information to assess the risk of NEPs. Landfilling is the most conventional method in disposing of municipal solid waste for the past many years. One of its major drawbacks is the production of highly contaminated leachate. Hence various types of alarming pollutants have evolved through leachate over the years. This study was set to conduct a quantitative approach in reviewing and analysing various past and present studies related to NEPs in landfill leachate. This research will involved a combination of Critical literature review (CLR) and Systematic literature review (SLR) based research, concluding results on NEPs from various studies. It was found from the review that NEPs in leachate consist of different compositions, a wide range of concentrations, and could be treated by various means. The leachate treatment for NEPs is mostly adapted from existing wastewater treatment technology. There is a growing trend in the discharge of NEPs in landfill leachate over the past 10 years. However, there are still gaps in the treatment technology as most of the current systems are not meant for advanced parameters such as NEPs. These results had provided future perspectives on the management of NEPs in landfill leachate as supported by various inputs from scholars in the field.
