The writing is on the wall for smog after the world’s first pollution-busting poem was unveiled by Sheffield University.
The new work, entitled In Praise of Air, by award-winning writer Simon Armitage, has been printed on special material containing a university formula capable of purifying its surroundings.
It is on a giant banner on the side of the Alfred Denny Building, part of the main Western Bank campus.
Professor Tony Ryan, who came up with the idea, said the cheap technology used could also be applied to billboards and advertisements alongside congested roads to cut pollution.
He said: “This is a fun collaboration between science and the arts to highlight a very serious issue of poor air quality in our towns and cities.
“The science behind this is an additive which delivers a real environmental benefit that could actually help cut disease and save lives.
“This poem alone will eradicate the nitrogen oxide pollution created by about 20 cars every day.”
The poem will be on display for one year, and its unveiling also marked the launch of this year’s Sheffield Lyric Festival staged at the university.
