A demonstration project at the Kirkwood Swine Facility at Kirkwood Community College in Cedar Rapids is pleasing to both smell and sight and that's just what Iowa State University (ISU) Extension livestock field specialist Terry Steinhart and ISU Extension agricultural engineer Greg Brenneman had in mind. They designed a biofilter for the exhaust system at the college's 10-stall farrowing house that would decrease odors and blend in visually with the surroundings.
