Dutch engineers are turning ordinary buildings into green, living ecosystems—literally. According to recent reports from the Netherlands, researchers have developed innovative “living bricks” that Support natural moss growth, transforming walls into vertical gardens that not only look stunning but help tackle urban Pollution and climate change.

These moss-covered bricks work like natural air filters. They absorb carbon dioxide and other air pollutants, actively purifying the surrounding air. And that’s not all—because moss retains moisture and thrives in humid environments, it also cools buildings by reducing heat absorption. That means these bricks can help cities stay cooler during increasingly frequent and severe heatwaves.
