Urban centers play a fundamental role in the advancement of contemporary architecture and in driving society's economic growth. At the same time, cities concentrate a large portion of the world's population and activities that contribute to global carbon emissions. This negative symbiotic relationship has brought us to a point where, according to WHO data, 99% of the global population breathes polluted air, consisting primarily of fine particulate matter and nitrogen oxide gases. These compounds have detrimental health impacts, linked to cardiovascular and pulmonary diseases.
Since these pollutants originate from human activity, it is crucial to seek approaches that reduce emissions and, from various angles, help improve air quality. These approaches range from adopting alternative construction methods for building structures and planning car-free urban environments to material innovations, including membranes with photocatalytic granules like those developed by Soprema. Through a photochemical reaction, these granules reduce pollutants at ground level, improving air quality and fostering healthier communities.
