Abstract
This paper examines an assessment method for terminating the post-closure maintenance of a landfill using a simplifiedlandfill gas model. The case study site is the Sudokwon Landfill in Incheon city, which was closed in 2000. The deviationsof the results obtained by the regular model and the simplified model were both slightly over 10% from the measured data.
Also, the deviation of the simplified model from the regular model has been less than 5% since 2005. Thus, the simplifiedmodel could be applied to other landfills that have been closed for at least 5 years. Additionally, the results of the massbalance analysis using the simplified landfill gas model indicated that 39% of the organic carbon was discharged, leadingto organic carbon and organic matter content of 7.2 and 17.6%, respectively, in the landfill by the end of 2018.
