National statistics of solid waste indicate that, although the amount of combustible wastes from household sectors is decreasing, the amount of waste that is buried in landfills increases each year. And the increasing rate of combustible wastes from industrial sectors is higher than the decreasing rate of combustible wastes from household sectors. Combustible waste, once screened, can be used as a potential energy resource contributing to resource circulation. Therefore, the objective of this study was to predict the amount of waste materials to be recovered and recycled by landfill mining and reclamation (LFMR), based on material flow analysis for four existing landfills. In this study, the landfills analyzed by material flow analysis were classified into types 1 to 4 by considering the status of the landfill and incineration situation. In order to perform material flow analysis, volume increase rate and bulk density were applied to the methodology employed in previous studies. In addition, material flow analysis software ‘STAN 2.0’ was used for the analysis. As a result of analyzing the average value of four landfills, the landfilled waste was classified as 93.9 m3 (73.7%) of combustible waste, 9.2 m3 (7.3%) of incombustible waste, and 24.3 m3 (19.1%) of soil matter. So, 73.7% can be incinerated or recovered by energy, 7.3% can be recycled as materials and reclaimed, and 19.1% can be recycled as landfill cover materials based on weight. The results of the material flow analysis carried out in this study are expected to be used to predict the amount of waste materials landfilled to be recovered by the material flow analysis during landfill mining processes.
