Determining Causes of Deep‐pit Swine Manure Foaming Issues and Potential Mitigation Strategies

As early as 2006, there have been incident reports of explosions, fires, and/or blue flames moving across manure surfaces in deep-pit swine facilities. In 2010, major explosions occurred damaging buildings from melted pipes to complete 100% loss. A task force of nine states in the upper Midwest held monthly conference calls to assess and plan strategies to determine the causes of these flash fires and possible mitigation solutions. Over the last five years, a major collaborative research project funded by the Iowa Pork Producers Association to understand and mitigate the causes of foam has been conducted by Iowa State University, University of Illinois, and University of Minnesota. Substantial new information has been learned about the foaming process, its potential causes, and the different methods of addressing it. That information will be briefly shared.

An application for continuing education credit for Certified Crop Advisors (CCAs) and members of the American Registry of Professional Animal Scientists (ARPAS) will be submitted.

Presenters for this webinar include:
  • Chuck Clanton, University of Minnesota
  • Dan Andersen, Iowa State University
Handouts (PDF format) will be available the day of the webinar at the live webcast information page.
