A first-of-its-kind study by Iowa State University scientists is seeking to fill the information gap that exists on air emissions from swine facilities.
“Farmers need reliable data to determine if air emissions are above regulatory thresholds and to help make better decisions on where to invest in emission controls,” said Hongwei Xin, professor in Iowa State’s Department of Agriculture and Biosystems Engineering.
Funded in part by the Iowa Pork Producers Association (IPPA), Xin and his research team are beginning to fill the information gap. Since January 2011, his research team has been quantifying ammonia and greenhouse gas emissions from a 4,300 sow breeding, gestation and farrowing facility located in central Iowa. The facility is owned and operated by Iowa Select Farms, the largest pork producer in Iowa.
