Technologies for Mitigating Air Emissions From Animal Housing

Reprinted, with permission, from the proceedings of: Mitigating Air Emissions From Animal Feeding Operations Conference.

Pigs

• A Receptor-Based Siting Strategy for Swine Production Systems – choosing swine housing sites using the point of view of the neighbors or others that will smell the odors
• Atomization Treatment to Improve Air Quality in a Swine Concentrated Animal Feeding Operation (CAFO)
• Practical Partial Biofiltration of Swine Exhaust Ventilation Air – biofiltration utilizes microbes that reside on the surface of an inert material (such as wood chips) to treat air and reduce odors
• Reducing H2S, NH3, PM, & Odor Emissions from Deep-pit Pig Finishing Facilities by Managing Pit Ventilation – hydrogen sulfide (H2S), ammonia (NH3), particulate matter/dust (PM)
• Vegetative Buffers for Swine Odor Mitigation – Wind Tunnel Evaluation of Air Flow Dynamics

Dairy

• Effects of Sodium Bisulfate in Reducing Emissions from Dairy Cow Slurry
• Effects of Waste Management Techniques to Reduce Dairy Emissions from Freestall Housing
• Environmental Responses to Dietary Monensin in Lactating Dairy Cows
• Management of Dairy Operations to Prevent Excessive Ammonia Emissions
• Methane Emissions from Dairy Cattle

Beef

• Water Requirements for Dust Control on Feedlots

Poultry

• Dietary manipulations to lower ammonia emission from laying-hen manure
• Dust and Ammonia Control in Poultry Production Facilities Using an Electrostatic Space Charge System
• Effectiveness of Litter Treatments for Reduction of Ammonia Volatilization in Broiler Production
• Efficacy of Vegetative Environmental Buffers to Mitigate Emissions from Tunnel-Ventilated Poultry Houses
• Feeding a Combination of Acidogenic Materials and Cation Exchangers Reduces Manure Ammonia Emissions and Improves Laying Hen Performance
• Litter Management Strategies in Relation to Ammonia Emissions from Floor-Raised Birds
• Manure Ammonia Emission Reductions Achieved by Feeding DDGS to Laying Hens Housed in a Production Environment
• Microbial Additives to Reduce Ammonia Emission from Poultry Houses
• Ozone Application for Mitigating Ammonia Emission from Poultry Manure: Field and Laboratory Evaluations
• Reducing Ammonia Emissions from Poultry Litter with Alum
• Siting of Livestock & Poultry Facilities Using MNSET
• The Use of Vegetative Environmental Buffers For Livestock and Poultry Odor Mitigation
• Use of Sodium Bisulfate to Reduce Ammonia Emissions from Poultry and Livestock Housing
• Using Klasp™ to Reduce Poultry Housing Ammonia Emissions
• Using Liquid Aluminum Sulfate to Reduce Poultry Housing Ammonia Emissions

The summaries below were applied in high-rise layer poultry houses, which are not typically built anymore (although many are still in use). The technologies mentioned should still have application to other types of housing systems.

• Dietary Manipulation to Reduce Ammonia Emission from High-Rise Layer Houses
• Effects of Aluminum Sulfate and Aluminum Chloride Applications to Manure on Ammonia Emission from a High-Rise Layer Barn
• Effects of EcoCalTM on Ammonia Emission from a High-Rise Layer House

Multiple Species

• Biofiltration: Mitigation for Odor and Gas Emissions from Animal Operations
• Effects of Dietary Manipulation on Ammonia Emissions
• Mitigation of Odor and Pathogens from CAFOs with UV/TIO2: Exploring Cost Effectiveness
• Multi-pollutant Scrubbers for Removal of Ammonia, Odor, and Particulate Matter from Animal House Exhaust Air
• Odorgon: Overhead Spray System to Neutralize Odors
• Pennsylvania’s Odor Siting Index
• Significant Odor Reduction from a Highly Efficient Micro-ecosystem based on Biofiltration
• Siting Animal Production Facilities and Evaluating Odor Control Options Using the Odor Footprint Tool
