Ammonia Emissions & Nitrogen Conservation

Purpose

This workshop is organized to provide animal producers and professionals with a better understanding of NH3 emissions, air regulations, and the best management practices and innovative technologies available for the abatement and recovery of NH3 to protect the environment and create a fertilizer used in crop farming.

Ammonia (NH3) emissions have become a significant environmental and public concern as it impacts human health, the ecosystem, and promotes the formation of small aerosol particles (PM2.5) which is a human health hazard. It is estimated that animal production contributes 80.9% of NH3 emissions to the atmosphere (about 2.4 million tons in 2002 estimated by the EPA).

As the price for nitrogen fertilizer increases there are concerns about the availability and price of nitrogen fertilizer for farming. In addition, the EPA announced the EPCRA ammonia reporting requirement in 2008, which requires animal operations to report their 24 hour NH3 emission exceeding 100 lbs. The increased public concerns and air quality regulations make animal producers subject to regulator enforcement of NH3 emissions. It is important to control NH3 emission on the farm as well as conserve nitrogen from food animal production facilities to protect the environment and meet regulatory obligations. Ammonia recover and conservation may provide an opportunity to enhance farm profitability and improve environmental quality.
