This Is Not Just A Static Piece Of Street Art,

it is working 24/7,

every week of the year, so what does this mural do? it has the same pollution-cleaning effect as planting 780 trees! thanks to a new type of paint,

the paint, called KNOxOUT, reacts with nitrogen oxides (NOx), created by cars, factories and power stations when they come in contact with the surface of the mural. Sunlight acts as a catalyst for a process that turns the nitrogen oxides into water, small amounts of CO2 and calcium nitrate. The calcium nitrate is washed away when it rains, leaving the canvas free to attract more pollutants,

organized by the sportswear company Converse as part of their City-Forests campaign, the latest mural in the Polish city of Warsaw,

Warsaw became the third city, after Bangkok and Belgrade, to host an eco-friendly mural like this, but more ‘City Forest’ murals are set to appear in Lima, Sydney, Jakarta, Manila, Sao Paulo, Santiago, Johannesburg, Melbourne, Bogota, and Panama City,

the main concept of Converse’s City Forest project is the idea of ‘planting trees’ where they might not otherwise be able to grow. Polish artists Maciek Polak and Dawid Ryski designed the image, but the actual painting was done by local artist hub Good Looking Studio, “My vision of a better future was well reflected on our project. I see it as a symbiosis of the city and nature, complementing each other perfectly,” Dawid said, the three murals created so far reportedly have the air cleaning capacity of 1,470 trees, I wonder why paint like this is not used more often?
