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.

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
