Abstract Life cycle assessment of sludge-aged refuse landfill with soil cover was conducted based on EASEWASTE which is developed by Danish Technological University. The results showed that the main impacts of the sludge landfilling were stored ecotoxicity via water (SETw),global warming (GW) and stored ecotoxicity via soil (SETs), which could be originated to Cu, CH4 and As in the wastes, respectively. The emission from sludge landfilling module was greater than that from pretreatment and transportation process. Therefore, pollution control should be enforced in landfilling process. The sensitivity analysis results indicated that the pollution could be alleviated through reducing the amount of leachate, increasing collection efficiency and utilization rate of landfill gas.
