Following over 12 months of development work with the University of Sheffield, Northern Flags has announced the completion of the printing, treatment and installation of a ground breaking 20m x 10m banner on the University of Sheffield’s Alfred Denny Building that turns textiles into a catalytic surface that purifies the air around it.
The banner has been manufactured using pioneering catalytic technology developed by the University’s Pro-Vice Chancellor for the Faculty of Science, Professor Tony Ryan and features the world’s first Catalytic poem written by the University’s Professor of Poetry, Simon Armitage.
After a series of comprehensive tests, the 20 metre high banner has been printed utilising dye sublimation techniques on a specially selected fabric to allow the absorption of catalytic chemicals. The banner contains microscopic pollution-eating particles of titanium dioxide, which, after coming into contact with nitrogen oxides in the atmosphere, react with these pollutants to purify the air. It’s the ultimate ‘Green Banner’ as it effectively cleans the air while it is being displayed and it is fully recyclable after use.
Iain Clasper, Managing Director of Northern Flags, comments, "This has been an exciting project to be involved with over the past 15 months and has capitalised on our group’s ability to work with clients on innovative projects. We are excited about this development as this now gives us the opportunity to work with our clients to roll out this type of treatment on their external marketing banners. It's a great innovation and will enable clients to clean the air around buildings and forecourts, ensuring that their fabric based promotional flags and banners are eco-friendly during their use as well as being recyclable after the campaigns have been completed.”
