Iowa State air quality research featured in The Economist

By The Economist

Jacek Koziel, associate professor of agricultural and biosystems engineering, and his research on improving air quality were featured in the Nov. 9 issue of The Economist.

“Research has found that improving the air quality of the places where pigs and other livestock are housed makes for healthier and more productive animals. The question is, how to do that cheaply? Jacek Koziel of Iowa State University reckons he has the answer: titanium dioxide and disco lights.”
