SUDOKWON Landfill Site
One of the largest sanitary landfill site in the world Operated from 1992 for treatment of waste generated by
21 million people living in SEOUL and its vicinity in Korea Consists of four large landfill sectors including landfill
sector #1 that caused the dispute with the local residents Became a target of public nuisance in the first half of the
1990s because of environmental degradation such as bad odor, dusts and noise, etc.
Landfill sector #2 is being operated at this time while the landfill sector #1 was closed down by expiration in 2000

Large-scale Waste Landfill Site
Waste landfill facilities larger than landfill capacity of 300 ton per day out of
Landfill sites that exceed the area of 150 thousands square meters
Should be assessed by the authorized environmental institutions every three years
Should open to the public the result of the environmental assessment
Should monitor the air quality, surface and ground water quality, noise level and soil contaminants seasonally obeying the Korean environmental regulations

Effect-Zone of Waste Landfill Site
Environmentally-adverse-effect-zone(EAEZ) is legally recognized the inner area of 2km from boundary line of landfill site
EAEZ of SUDOKWON landfill site had been recognized exceptionally the inside of 5km from boundary line of landfill site for smoothing down the residents’ complaints in 1996
The research team of YONSEI and INHA University had reported that EAEZ of SUDOKWON landfill site could be scaled down to the 2km zone
Based on the comprehensive environmental assessment during 2004~2005

Step 2 : Prediction of the future environmental quality
Step 3 : Scoring the future environmental quality levels
Step 4 : Summation of environmental score to 500mx
500m grids map
Step 5 : Marking out a boundary line that significantly
over the residential environment quality
