Pollution Reducer & Heat Generator

New technology from North Carolina State University and West Virginia University can reduce air pollutant emissions from some chicken and swine barns while also reducing their energy use by recovering and possibly generating heat. A proof-of-concept unit incorporates a biofilter and a heat exchanger to reduce ammonia emissions.
