In the bustling cityscape of Warsaw, Poland, a splash of color breathes life and purity into its surroundings. A large, vibrant mural, featuring cheerful plants and flowers interwoven with avant-garde edifices, graces the walls opposite the Politechnika metro station. But this isn’t just any piece of art—it’s a living, breathing testament to the power of technology and creativity to combat air pollution.

The mural is not merely decorative—it’s functional. Crafted using KNOxOUT™ paint, this innovative medium possesses the unique ability to reduce atmospheric pollutants.

The science behind it is simple yet profound. When nitrogen oxides (NOx), notorious pollutants emitted from vehicles, industries, and power stations, make contact with the mural’s surface, they undergo a transformative process. Sunlight, acting as a catalyst, facilitates a reaction that converts the harmful NOx into water, minuscule quantities of carbon dioxide (CO2), and calcium nitrate.

With each spell of rain, the calcium nitrate—a benign byproduct—is washed away, revealing a refreshed paint surface, eager and ready to cleanse the air once more.

City Forests: Converse's Vision for a Greener Tomorrow

American shoe manufacturer Converse is the powerhouse behind this groundbreaking endeavor, christening it "City Forests." The initiative resonates with the imperative of infusing urban jungles with nature's vitality. At the heart of this project is the emblematic idea of "planting trees" in spaces where they might be impossible to grow, at least in the traditional sense.

Warsaw's mesmerizing mural is just a fragment of a more extensive global project. Murals sharing the same eco-friendly attributes already adorn walls in Bangkok and Belgrade. With twelve such murals envisioned in the grand blueprint, Converse's ambition for a cleaner atmosphere is clear. The shoe giant estimates that the combined air-purifying prowess of these artworks rivals that of a whopping 1,470 trees.

Local artists Dawid Ryski and Maciek Polak are the visionaries behind Warsaw's eco-friendly masterpiece. Their artistry, coupled with their commitment to a sustainable future, gave birth to this fusion of beauty and functionality.

Sharing his vision, Dawid Ryski muses, “In my dream future city, billboards would disappear, and everybody here would switch from cars to bicycles.” True to his aspiration, Ryski has depicted a cityscape devoid of intrusive advertisements. “I tried to make sure that these were actually the buildings of the future—as you can see, they are free from billboards, and that Maciek could fit in his plants beautifully,” he adds, emphasizing the symbiotic partnership between the duo.

Maciek Polak, known for frequently incorporating vegetation into his art, enriches the mural with nature-inspired motifs. “I think that nature is a perfect inspiration for an artist’s work because it has endless possibilities in terms of shapes, colors, and forms,” Polak explains, elucidating his artistic inclinations.

As the world grapples with the challenges of climate change and environmental degradation, innovations like the KNOxOUT™ paint and the City Forests initiative point towards a brighter, cleaner future. Such projects underscore the potential of bridging the divide between art and science to forge solutions for contemporary challenges.

The Warsaw mural stands as a symbol of hope, illuminating a path towards a more sustainable urban existence. It invites the world to reimagine cityscapes, not just as hubs of human civilization, but as spaces where nature and technology coalesce, championing a future where the air is clean, and cities are as alive as the forests they seek to emulate.

Thes science behind KNOxOUT™ paint

This technology uses light energy to break down noxious air pollutants and converts them into harmless substances. Any surface coated with KNOxOUT™ becomes an active air-purifying surface that helps protect people from harmful gases.

KNOxOUT™ is ideal for areas with high NOx levels, such as:

  • Urban areas with heavy traffic

  • Industrial areas with factories and power plants

  • Indoor spaces with poor ventilation

KNOxOUT™ can also be used to improve air quality in homes, offices, and schools. It is non-toxic and safe for use indoors.

Here is how KNOxOUT™ works:

  • The paint contains titanium dioxide (TiO2), which is a semiconductor.

  • When light hits the TiO2, it releases electrons.

  • These electrons react with water vapor in the air to form hydroxyl radicals.

  • Hydroxyl radicals are highly reactive and can break down harmful air pollutants, such as nitrogen oxides (NOx) and volatile organic compounds (VOCs).

  • The NOx and VOCs are converted into harmless substances, such as water and carbon dioxide.

In addition to its air-purifying properties, KNOxOUT™ also has self-cleaning, antibacterial, and deodorizing properties. This makes it a versatile and effective paint for a variety of applications.

Here are some of the benefits of using KNOxOUT™ paint:

  • Improves air quality

  • Reduces harmful pollutants

  • Self-cleaning

  • Antibacterial

  • Deodorizing

  • Safe for use indoors

  • Non-toxic
