Annual Dairy Discussions Seminar on Dec. 1 will focus on “Manure Management Practices and Opportunities in Renewable Natural Gas (RNG)”

The Iowa State University Extension and Outreach Dairy Team will host its annual Dairy Discussions Seminar on Tuesday, December 1, from 10 a.m. to noon. The program is sponsored this year by EcoEngineers, a renewable energy consulting and auditing firm headquartered in Des Moines, Iowa, and the Iowa Economic Development Authority (IEDA). The program will be virtual due to health concerns with the COVID-19 pandemic.

This year’s focus is on manure management systems, opportunities in renewable natural gas (RNG) to maximize profitability in the dairy industry, and the benefits of co-locating a dairy near a biofuel facility in the Midwest. The presentations will include a case study for an Iowa dairy and the minimum project size to make RNG project economics work.

The key presentations include:

  • “Supporting Dairies in Iowa: How the IEDA can help,” Shelly Peterson, P.E., IEDA
  • “Successful Manure Systems,” Kris Kohl, Ph.D., Iowa State University
  • “Dairy Opportunities in RNG and Location Benefits” Brad Pleima, P.E., EcoEngineers
