N. Kennedy, G. Yorgey, C. Frear, D. Evans, J. Jensen, C. Kruger. 2015. WSU Fact Sheet FS180E. This fact sheet is to provide farmers, third party project developers, regulatory agencies, and other stakeholders with a basic understanding of the chemical composition of renewable natural gas, the most appropriate end-use options for dairy digesters, and some of the more common techniques used to clean biogas to RNG quality at dairy digesters. In describing specific technologies, the authors aim to provide information based on the current literature, but not to favor one technology over another. For additional detail or information about other technologies, more comprehensive reports and reviews are available (Krich et al. 2005; Ryckebosch et al. 2011; Jensen 2011).
N. Kennedy, G. Yorgey, C. Frear, C. Kruger 2015. WSU Fact Sheet FS172E. Anaerobic Digestion Systems Series provides research-based information to improve decision-making for incorporating, augmenting, and maintaining anaerobic digestion systems for manures and food by-products. This publication focuses on pre-consumer food wastes that can sustainably be used as substrates for co-digestion with dairy manure and increase the value of co-products. Topics covered include complementary and problematic substrates, the substrate procurement process, regulations, and solutions for co-digestion processing issues.
S. M. Mitchell, N. Kennedy, J. Ma, G. Yorgey, C. Kruger, J. L. Ullman, C. Frear. Sept 2015. WSU Fact Sheet FS171E. Anaerobic digesters are used worldwide to produce bioenergy and sustainably treat organic waste from municipal, industrial, and agricultural operations. This fact sheet reviews the basic elements of anaerobic digestion and the process used by digesters, including the types of digesters, biochemistry of influents and effluents, laboratory evaluations and optimizing anaerobic digesting through modeling.

Increasing resilience among cereal-based farmers in the Inland Pacific Northwest – Farmer to Farmer Case Studies
Yorgey, Georgine, Kathleen Painter, Hilary Davis, Kristy Borrelli, Sylvia Kantor, Leigh Bernacchi, R. Dennis Roe, Chad Kruger 2014. Video and print case studies part of REACCH PNA project. The goal of these case studies to inspire others to take management risks on their farms that can improve their overall sustainability and resiliency into the future. Future case studies are in progress and will focus on farmers who manage water in irrigated systems, tillage practices and residue management in unique ways.
