PRÉDIOS QUE ABSORVEM POLUIÇÃO
Na Itália, na Cidade do México ou em Sheffield, na Inglaterra, materiais inovadores neutralizam ar poluído.
BUILDINGS THAT ABSORB POLLUTION
Italy, Mexico City or Sheffield, England, innovative materials neutralize polluted air
Buildings that capture rainwater for reuse or shelter urban gardens are already known, but what about buildings that literally serve to filter air pollution? Because they exist. The design office Nemesi & Partners, Rome, for example, has developed a building project built with 9000 square meters of photocatalytic concrete - a type of material that absorbs nitrogen oxide and nitric oxide when exposed to sunlight. In Mexico City, the specialties Tower - home to the hospital Manuel Gea Gonzalez - has its facade surrounded by a painted structure with a compound called Prosolve370e, which also neutralizes toxic substances from the polluted air. And the University of Sheffield in England, created the first catalytic poem in the world, using as support for the mural an invented material in the university that helps purify the air - installed in the gable of one of the buildings, the wall absorbs the daily emissions 20 vehicles.
The material used in Specialties tower, in Mexico, was developed by the office Elegant Embelishments, Berlin: the ink applied on the facade is made of titanium dioxide pigment which acts as a catalyst in certain chemical reactions. When UV rays reach the structure of the building, it triggers a chemical reaction between titanium dioxide and nitrogen monoxide contained in the polluted air, neutralizing its harmful elements without changing, however, the pigment. The shape of the building facade of the structure resembles a beehive, but not for aesthetic or visual reasons: it can spread more sunlight and therefore generate more chemical reactions that will "suck" pollution.
