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.

Kennedy, N., G. Yorgey, C. Frear, and C.E. Kruger. July 2016. WSU Fact Sheet EM088E. This publication discusses the impacts of incorporating co-digestion at dairy-based anaerobic digesters. That is, mixing manure with non-manure waste in anaerobic digesters. This information is based on stakeholder perspectives and a literature review of infrastructure, operational upgrades, and related costs and revenues when non-manure wastes are added to dairy digesters. This fact sheet is part of the AD Systems Series.
