SMOG FREE PROJECT is a series of urban innovations led by Daan Roosegaarde to show the beauty of clean air. Roosegaarde creates SMOG FREE RINGS made from the compressed smog particles collected from the SMOG FREE TOWER as a tangible souvenir. By sharing the SMOG FREE RING you donate 1000 m3 of clean air to the city.
SMOG FREE RING is now part of the permanent art collection of the Utah Museum of Fine Arts USA, Stedelijk Museum Amsterdam, National Museum Zurich and The Biosphere Environment Museum in Montreal.
Winner of the Ethics Ethical Award 2019.
