A photocatalytic treatment aims to improve air quality on the M-30
Photocatalysis applied to a section of the M-30 uses ultraviolet rays to purify the air. The chosen area is on Avenida de La Ilustración y Calle 30, and there were plans to extend the treatment to more than 40,000 metres.
On Avenida de La Ilustración, traffic lights and heavy traffic are typical of the stretch of the M-30 where the described treatment is applied. Here, cars drive in low gears and, according to available information, tend to pollute more.
The technique is photocatalysis. It is applied to the road surface and uses ultraviolet rays to purify the air; the information also credits it with helping to humidify the air. The treatment is described as colourless and odourless.
Calle 30 had planned to extend the application to more than 40,000 metres in the capital.
