Incheon City Expands Road Dust Collection System... 1380m Sections to Be Installed in 4 Districts Next Year

Incheon City will expand the installation of road dust collection systems to reduce high concentrations of fine dust.

The city announced on the 22nd that following the installation of dust collection systems along approximately 200 meters of roads near two elementary schools in Gyeyang-gu this year, it plans to newly install this system along a 1,380-meter section in four districts including Jung-gu and Namdong-gu next year.

The system collects road dust by installing dust collection devices in the drainage channels along the road curbs, capturing dust stirred up by vehicle winds. The collected dust is discharged into rivers through stormwater drains by rainwater and water-spraying vehicles.

Previously, Incheon City confirmed through a pilot project on some roads in Yeonsu-gu in 2021 that a 1-meter collection system could capture 350 mg of fine dust and 88 mg of ultrafine dust per day. Additionally, last year, after installing the collection system along approximately 730 meters on Bongsu-daero and Gyeongmyeong-daero, the road dust reduction rate reached 57.2%.

Road dust refers to dust accumulated on roads due to vehicle exhaust, tire wear, and brake pad wear, which is re-suspended into the atmosphere by vehicle movement. It accounts for 35.3% of the total fine dust (PM10 standard) emissions in the Incheon area.

An official from Incheon City stated, "In addition to the dust collection system, we plan to deploy vehicles that directly remove dust and introduce fine dust adsorption filters to reduce fine dust."
