The Cleantech Open runs the world’s largest cleantech business competition and the first ever global cleantech ideas competition. Its mission is to find, fund and foster entrepreneurs with big ideas that address today’s most urgent energy, environmental and economic challenges.

Selected from the five regional winners of the prestigious Cleantech Open Business Competition, the National Grand Prize was awarded to Puralytics of Beaverton, Oregon. Puralytics develops photochemical water purification products designed for critical contaminants such as petrochemicals and pharmaceuticals. Puralytics uses light (from LEDs or natural sunlight) to create processes that totally remove contaminants from the environment without any wastewater or chemicals.
