Gwangju Agricultural Technology Center, Pilot Operation of Air Purification System 'Bio Wall'

[Asia Economy Honam Reporting Headquarters Reporter Park Seon-gang] The Gwangju Metropolitan City Agricultural Technology Center announced on the 24th that it will pilot operate a plant air purification system called ‘Bio wall’ at Sangmu Station of the subway.

The Bio wall is a plant air purifier that combines air-purifying plants and wall greening by absorbing and purifying fine dust and pollutants (volatile substances, etc.) through plant leaves and adsorption by cultivated soil.

According to research by the Rural Development Administration, 2% of plants relative to the volume of living space can reduce fine dust by 12-25%, and the fine dust reduction effect of the Bio wall is proven to be about seven times higher than that of plants planted in pots.

This Bio wall installation was promoted as part of the ‘Green Platform’ project to improve air quality and provide citizens with a comfortable resting space through wall greening using air-purifying plants at subway stations, where air pollution is severe due to high foot traffic and the characteristics of enclosed spaces.

The Bio wall created at Sangmu Station subway will consist of seven types of air-purifying plants such as Scindapsus and Spathiphyllum on an 8.4㎡ wall near exits 5 and 6.

Yang Hee-yeol, head of the Agricultural Technology Center, said, “Considering the serious air pollution such as fine dust and the lack of green spaces especially in urban areas, the Bio wall is a very efficient system environmentally and spatially,” and added, “We will gradually expand it to create not only environmental improvements but also physical and psychological healing spaces for citizens.”
