New technology removes air pollutants, may reduce energy use in animal facilities

摘要

Researchers from North Carolina State University and West Virginia University have developed a new technology that can reduce air pollutant emissions from some chicken and swine barns, and also reduce their energy use by recovering and possibly generating heat.Specifically, the research team designed, built, and evaluated aproof-of-concept unit that incorporates a biofilter and a heat exchanger to reduce ammonia emissions from livestock barns, while also tempering - or heating up - the fresh air that is pumped into the barns.
