RESEARCHERS USE SUPERCRITICAL FLUIDS FOR ENVIRONMENTAL CLEANUPS COLUMBUS, Ohio -- A process currently used to decaffeinate coffee may also be useful in removing organic waste from soil, according to researchers at Ohio State University. Manufacturers now use a supercritical fluid to remove caffeine from coffee beans. Using a similar technique, scientists have been able to remove contaminants such as DDT from soil, said David Tomasko, an assistant professor of chemical engineering. A supercritical fluid is created when the pressure and temperature of a compound are increased beyond the critical point where the gas and liquid physical states can no longer co-exist. At that point, the compound is in a single state and will
