312: Murals, pollution-eating

Problem:

Murals or wall paintings proliferate in big cities but are only decorative.

Solution:

Pollution-eating paint.

Since 2007, Massimo Bernardoni and Antonio Cianci of Airlite in Milan and London, have developed Sunlight Exterior one of a range of paint colours which contain special compounds that absorb and eliminate pollutants in the air by 88%, similar to photosynthesis in plants. A study in Rome’s Umberto tunnel found that after it was painted with a similar photocatalytic paint, nitrogen oxide levels were reduced by over 50%.

Sponsored by Veronica De Angelis, real estate entrepreneur and founder of Yourban2030, Milanese street artist Federico Massa (aka Iena Cruz) using the Airlite palette unveiled her work ‘Hunting Pollution,’ which spanned 1,000-square-metres, on the side of seven-story building in the capital.

In Rome, the Dutch street artist JDL (Judith de Leeuw) has painted another giant mural on a gable end of a building. Paying homage to the LGBTQ community by depicting a woman standing in front of a mirror seeing her reflection as a man, the mural is absorbing the pollution generated by 52 cars every day.

Airlite is planning to focus on large contracts and infrastructure projects like hospitals, schools, air quality in tunnels and the like.
