The new bridge in Barcelona ‘eats’ CO2

The Sarajevo bridge in Barcelona gets a green makeover. The Spanish architect BCQ redesigned the bridge.

The bridge will have a renovation turn with photocatalytic concrete, which purifies the air.

Smog will stick to the concrete and be degraded by photocatalysis. The rain washes away the waste then. So the air stays around the bridge purer. And the bridge itself remains cleaner.

The material in the concrete used will sunlight polluted air convert into oxygen, water, CO2, nitrate and sulfate. The catalyst in the process is titanium dioxide.

Students at the University of California used the same principle to purify the air with tiles. According to their calculations about 18,000 roofing compensates car mileage per year.

Closed electricity circle

According to the architects BCQ Sarajevo bridge itself provides its electricity.

The lighting consists of LED lights that are powered by solar panels.

The pavement has glow-in-the-dark elements which that light at night.

Vegetation and pergolas provide shade during the day.
