SMOG FREE PROJECT is a series of urban innovations led by Daan Roosegaarde to show the beauty of clean air. As a tangible souvenir, Roosegaarde creates SMOG FREE RINGS made from the compressed smog particles collected from the SMOG FREE TOWER. 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 Stedelijk Museum Amsterdam, National Museum Zurich and The Biosphere Environment Museum in Montreal.
Winner of the Ethics Ethical Award 2019.
