A descendant of German and Norwegian immigrants that settled in Iowa between 1850 and 1873, Bryan Sievers, and his wife Lisa, are the current generation of owners and operators of the Sievers’ farm. Bryan is an enthusiastic environmental steward of the land and takes pride in using all available resources, including the air, land, water, and sun for their highest and best use. The Sievers’ 2,300-acre farming operation, 2,400 head beef cattle feedlot, and renewable energy facility is located in western Scott County, Iowa near Stockton.
In 2009, this philosophy became the motivation behind implementing the combined heat and power (CHP) anaerobic digester project. The Sievers were looking to dramatically expand the farm’s beef cattle feedlot but had concerns about any of the expansion’s effects on their carbon footprint, water quality, soil health, and the environment. The solution was a 1 MW CHP system fueled by the methane produced from two 970,000 gallon anaerobic digesters utilizing beef cattle manure, agricultural processing waste streams, cover crops, and other co-feeds.
AgriReNew, a company created by the Sievers and their partners, Dr. William and Judy Davidson, commissioned their digesters and CHP power plant in 2013. Today, the digesters process over 55,000 gallons per day of cattle manure and other off-site co-feeds in the complete-mix system. The electricity that’s generated, 24 hours per day 7 days per week, is sold to their local service provider, Interstate Power and Light (Alliant Energy).
In 2014, AgriReNew received the Agricultural Biogas Project of the Year Award from the American Biogas Council and received the 2014 Iowa Environmental Excellence Award for their anaerobic digester project.
Bryan and Lisa are 1982 graduates of Iowa State University. Bryan received his degree in Agricultural Business while Lisa received her degree in Industrial Administration with an emphasis in Accounting. Lisa is also a Certified Public Accountant.
