Hall, S., and G.G. Yorgey. 2017. Produced by CAHNRS Communications. Washington State University, Pullman, WA. This video profiles two Washington State dairies – Edaleen Dairy and Royal Dairy – who have implemented new technologies that partition, and in some cases recover, some of the nitrogen and phosphorus in manure. The video discusses both the potential that these new tools have to improve manure management for dairies, and some of the challenges that remain.

Research and outreach website. This project was directed by Gregmar I. Galinato, with co-directors Suzette P. Galinato, C. Richard Shumway, and Jonathan K. Yoder. In an era of increased concern about the influence of carbon on the environment, the U.S. government has intervened, requiring the use of biofuels in an attempt to reduce dependence on fossil fuels. This project focuses on one of those biofuels, cellulosic ethanol, and the countervailing forces influencing its development, especially in the Pacific Northwest.
