Additional Progressive Dairyman Articles by Katers and Holzem

Katers, Holzem contribute articles on waste management to dairy publication Natural and Applied Sciences Profs. John Katers (of EMBI) and Ryan M. Holzem (of the new Environmental Engineering Technology program) recently wrapped up a three-article series for the Progressive Dairyman magazine. Karen Lee, the editor, asked Katers and Holzem to address considerations for using digesters on large dairy farms. The Progressive Dairyman print and online editions reach more than 25,000 large-herd, forward-thinking producers throughout the United States. The April and June articles are summarized below:

* “Considerations for sizing an anaerobic digester,” published online on April 28, 2015, described the need to properly quantify and characterize the manure and water sources that would end up in the digester, and use the appropriate hydraulic and solids retention times to obtain optimal digestion.
