Filtration towers designed to absorb the smog of Delhi
Delhi, India’s capital territory, is the most polluted city in the world, according to the World Health Organisation.The city’s excess of industrial waste, diesel vehicles, crop burning and power plants have led to severely poor air quality. The number of carcinogenic pollutants in Delhi’s atmosphere are currently ten times higher than those in Beijing, China. Dubai-based architecture studio Znera seeks to combat this urgent problem and make Delhi a more liveable city — through a grid of 100-metre high-towers that would absorb smog and generate clean air.
The proposal, known as “The Smog Project,” features filtration pods at the base of each tower which capture pollutants at the level where people breathe. Meanwhile, propellers at the top of towers will circulate the filtered result, creating a 1.9km radius of cleaned air.
Znera claims that each tower will produce 3.2 million cubic metres of clean air each day, to reduce pollution to moderate levels, with bridges connecting vertical air purifiers that are arranged at key points in the city in a hexagonal grid.
The anti-pollution towers are fuelled by hydrogen fuel cells and solar energy, located in the bridges. According to Znera, carbon particles sucked in by the filters also have further uses, able to create concrete, graphene, or even ink, an innovation spearheaded by Indian startup company Graviky Labs with their product Air Ink.
The Smog Project has been shortlisted for the Experimental Future Project of the Year award at this year’s World Architecture Festival.
