Abstract

The calculation of the waste landfill unit price at the S landfill located in I city was analyzed in two cases: Method A by statistical techniques and Method B by reflecting policy variables such as the prohibition of direct landfilling of household waste and the right to emit greenhouse gases. As a result, in the case of method B, the landfill unit price increased by 34.1% to 57.6% depending on the type of waste compared to method A. By landfill unit price composition, landfill work cost, operation and management cost, greenhouse gas emission rights transaction cost, and resident support fund increased by 61.0%, 68.3%, 63.5%, and 34.1% to 57.6%, respectively. Therefore, considering the characteristics of the landfill, which requires more than 30 years of mid- to long-term operation and management even after the end of the landfill, policy variables should be identified periodically for stable landfill operation and management. In addition, periodic activities to calculate the landfill unit cost are considered necessary, such as predicting the amount of landfill waste and deriving additional future cost factors such as greenhouse gas emission rights.
