David Grewell, professor of agricultural and biosystems engineering, and Eric Cochran, associate professor of chemical and biological engineering, are working to develop an adhesive that consumers can purchase and use. The duo is using a product made from a byproduct of biodiesel production, which was formerly a waste material in the process. The project is funded by a grant from the U.S. Department of Agriculture.
