The largest pork producer in Iowa is taking new steps to beautify and cut down on confinement odors, reports Radio Iowa. Iowa Falls-based Iowa Select Farms will be installing an electrostatic precipitator fence around all company-owned farms built in 2018, environment project manager John Stinn said. The system requires high-voltage wires to be installed behind fans in the end of the barn. As dust particles leave, they are charged by those wires and then are attracted to a green screen fence, preventing the dust from leaving the barn. “By reducing the dust that leaves the farm, we also reduce the odor,” Stinn told Radio Iowa.
