Singapore is experimenting with vertical algae panels installed along busy highways to tackle urban air pollution in an innovative way. These tall, transparent columns are filled with living microalgae that actively absorb carbon dioxide emitted by passing vehicles while releasing oxygen back into the environment. Unlike traditional concrete sound barriers or metal dividers, these algae panels function as biological air filters. As traffic flows, the algae feed on CO₂ and nitrogen compounds, con
