University of Buffalo students in the Department of Civil, Structural and Environmental Engineering performed a comparative study of Dyson Airblade versus paper towels and found that six times more bacteria grew on paper-towel dispenser push-and-crank handles than on the hand dryers. They also determined that, over their life cycle, the Dyson Airblades were superior to paper towels in both economic and environmental analyses, producing 42 percent less carbon dioxide and running under $28 per year in energy consumption (paper towels cost more than $900 per year with the traffic footprint of the bathrooms).
The research team was awarded second place in the 2014 New York State Pollution Prevention Institute’s R&D Student Competition. The contest funds the students and provides them with the chance to design solutions to real-world environmental challenges.
