The subject of the 1st SGC was “Proposals on reducing fine dust levels in the Seoul Subway.” The Challenge brought together 106 companies from all parts of the world, including the United States, France, and Japan as well as Korea, who introduced their products for competition in three categories -- tunnel, platform, and train.
The solutions selected as finalists were installed in the Seoul Subway to test their effectiveness in reducing fine dust levels.
As a result, three teams were selected as winners with the most effective solution. KRW 500 million in prize money was awarded to the first-place winner and KRW 50 million each for two category winners.
First-place winner Corning took part in the Challenge’s platform category by introducing its solution using its own ceramic honeycomb filters.
In the platform category, Allswell was named as the winner; it introduced its solution where its airflow control technology improved air quality by optimizing the existing ventilation system and effectively removing fine dust particles in the platform area.
Han-lyun System won in the train category by showcasing its solution where air purifiers for trains combined with air curtains for train doors removed fine particles and let the purified air stay in train cars.
This year, the SGC 2020-2021 will take place, where innovators with novel ideas for fine dust reduction for the Seoul Subway will be selected and given support for the development of trial products. You can apply for the upcoming Challenge on the official website of SGC (www.seoul-tech.com/seoulglobalchallenge/eng) in April.
Innovation Growth Division Managing Director Kim Seong-min of the SBA, which organized the Challenge, said, “The Challenge will be a step toward a better environment for Seoul citizens with lower fine dust levels in the Seoul Subway system and we at the SBA will continue to take the lead in solving urban problems facing Seoul by organizing the SGC under a variety of subjects.”
