Creation of a new kind of sanitation industry could be a big part of the solution to at least one of world’s climate change challenges. Researchers at ASU’s Center for Negative Carbon Emissions, directed by Fulton Schools Professor Klaus Lackner, are refining technology that can remove carbon dioxide from of the air. The buildup of carbon dioxide in the Earth’s atmosphere is a major cause of global warming. Lackner views the system as a garbage removal tool to clean the air. He says the captured carbon dioxide could be stored and sold for productive uses — giving rise to profitable business ventures.
