In this study, we analyzed all of the waste streams associated with household waste to provide a basis for incorporating the individual characteristics of municipalities in setting targets for waste-to-resource circulation. Toward this end, we examined how household waste is treated based on the disposal method (mixed waste disposed of in standard volumerate garbage bags, separation recyclable waste, and food waste) and the amount of residuals generated at their respective treatment facilities. The actual recycling rate or actual waste-to-energy conversion rate was calculated as the ratio of the actual amount of waste that is recycled or converted to energy against the amount of waste intake at waste treatment facilities. The conversion factor of actual recycling rates at 17 municipalities showed an average of 63.9% for public material recovery facilities (MRFs) with those for individual municipalities ranging from 50.4% to 93.2%, and an average of 93.8% for private and public food waste treatment facilities with slightly higher rates found for public facilities (70.4 ~ 100%) than private facilities (63.3 ~ 100%). The actual waste-to-energy conversion factor was 59.3% on average for combustible waste-to-energy facilities (17.2 ~ 72.3%) and 92.0% on average for biological waste-to-energy facilities (77.1 ~ 99.5%). To achieve the national target for the actual recycling rate, additional strategies for recycling or converting the residuals generated at recycling or combustible waste-to-energy facilities into resources are needed. The actual recycling and waste-to-energy conversion rates provided in this study based on a full examination of household waste streams hold valuable insights for incorporating the individual situations of municipalities in setting their targets for wasteto- resource circulation indicators and creating new strategies for improving the actual recycling rate.
