Can concrete outdoor seating be made with photocatalytic materials to reduce air pollution?

Concrete outdoor seating embedded with photocatalytic materials is an innovative solution to combat air pollution in urban areas. Photocatalytic concrete contains additives like titanium dioxide (TiO2), which react with sunlight to break down harmful pollutants such as nitrogen oxides (NOx) and volatile organic compounds (VOCs) into harmless substances.

This technology not only enhances the durability of outdoor furniture but also contributes to cleaner air. When exposed to UV light, the photocatalytic process oxidizes pollutants, reducing their concentration in the surrounding environment. Cities like Tokyo and Milan have already implemented such materials in pavements and benches, demonstrating measurable improvements in air quality.

Beyond pollution reduction, photocatalytic concrete is low-maintenance and cost-effective over time, making it ideal for public spaces. As urban areas seek sustainable solutions, integrating this material into outdoor seating could be a practical step toward greener cities.

Would you support using photocatalytic concrete in your community’s public spaces? The potential benefits for both the environment and public health are compelling.
