To change from a linear economy to a circular economy, the necessity of recycling scarce resources through recycling waste is emerging. In South Korea, the concept of landfill mining has been introduced as a way to convert landfills into resources, and recycling-type landfills are being created. In this study, the operation status of domestic municipal waste landfills was identified, and the amount of resource recovery according to the renovation of a circular landfill was calculated. Of 215 public landfill sites, 67 landfill sites that have been used or have a residual landfill rate of less than 40% were investigated, and the total amount of waste landfills here was confirmed to be 68,509 thousand m3. Among landfill wastes, the energy production potential from combustible wastes was calculated to be 55,835,540 Gcal when energy was recovered through stocker-type incineration. The amount of recovered valuable resources among landfill wastes was estimated to be 1,065 thousand tons. As a result of evaluating the potential for recycling of major metals, trace metals, and rare earth elements contained in incineration ash, the content of Fe among major metals such as Fe, Al, Cu, and Zn was in the range of 27,280 to 245,517 tons, which is the national integrated resource management system. The possibility of circular use was confirmed as the range of the mass flow analysis statistic was similar. In the case of trace metals, the content ranges of Cr, Pb, and Co were 162 to 1,716 tons, 99 to 875 tons, and 35 to 64 tons, respectively, similar to the statistics. In the case of rare earth elements with high potential value as future resources, national statistics were absent or recent data were insufficient, but in the case of Dy, a similar content could be confirmed. 70% of the total landfill capacity can be used for the recycling landfill capacity according to the composition of the recycling landfill, and when the municipal waste is finally disposed of after resource recovery in the recycling landfill, the lifespan of the existing landfill can be extended by more than 5.4 times.
