Smog Free Project is a campaign for clean air led by Daan Roosegaarde to reduce air pollution and provide an inspirational experience of a clean future, including a series of urban innovations such as the Smog Free Tower which provide a local solution of clean air in public spaces.
The Smog Free Tower is being used in Rotterdam, Beijing, Tianjin and Dalian, to suck up 30,000 cubic meters of polluted air per hour, cleans it at the nano level — the PM2.5, PM10 particles — and then releases the clean air back into the city.
The tower is powered by solar energy.
It’s incredibly effective: the air around the tower is 55 to 75 percent cleaner than the rest of the city.
The material which was collected after the cleaning of smog had 42 percent carbon particles so they decided to compress them and convert them in diamonds.
The smog particles were compressed for 30 minutes and turned into dark, boxy gems. The diamonds are then used for rings and cufflinks, each representing 1,000 cubic meters of pollution.
This is the ultimate waste-to-wonder conversion: toxic pollution transformed into gemstones.
