Category Unit 2025 2024 2023 2022 2021
Waste Managed through Volume-Based Waste Disposal Bags2) Ton 28 23 20 14 27
Waste Managed by Licensed Waste Disposal Contractors3) 18 15 22 20 12
Total General Waste Generated 47 38 42 33 39

    - All figures are rounded to the nearest whole number. As a result of rounding, the total may not exactly match the sum of individual figures.

  2. 2) Waste Managed through volume-based waste disposal bags is calculated using the calculation methodology of the Environmental Information Disclosure System operated by the Korea Environmental Industry & Technology Institute (KEITI). Due to a change in the calculation methodology—applying the non-household (volume-based waste disposal bag) density from the 6th National Waste Statistics Survey (2022)—the reported waste generation data for 2022-2024 may differ from those disclosed in previous reports.
  3. 3) Due to a change in the calculation methodology, the reported waste generation data for waste managed by licensed waste disposal contractors for 2022-2024 may differ from those disclosed in previous reports.
