A wall that absorbs air pollution is as effective as 780 trees

 

In the Polish capital, Warsaw, a large wall of a building is now the focus of attention on social media as well as the general public. Apparently the wall is painted using ordinary paint, but in reality the same paint absorbs as much air pollution of nitrogen oxides as 780 trees can. Nitrogen oxides are a major cause of smog.

The paint contains dyes as well as special compounds called "photocatalysts" that attract air pollution of nitrogen oxides and, using ultraviolet rays from the sun, help them absorb moisture. Converts harmful gases into harmless substances.

Water washes away these substances and thus the wall is ready to absorb the pollution again.

The wall on which it is painted in Warsaw is very large and can absorb as much nitrogen oxide as a total of 780 trees can.

Called "KNOxOUT", the paint was invented by BOYSEN, a Philippine company, and its formula is owned by the same company.

Large paintings from Knoxout have previously been erected on the walls of buildings in Bangkok and Belgrade. Warsaw is the third city on the list, while "Knoxout" paintings appear on high-rise building walls in Lima, Sydney, Jakarta, Manila, Sao Paulo, San Diego, Johannesburg, Melbourne, Bogota and Panama City.
