Research Project: ABATEMENT MEASURES FOR REDUCING ODOR, VOC, AND GREENHOUSE GAS EMISSIONS FROM ANIMAL FEEDING OPERATIONS
2013 Annual Report


1a.Objectives (from AD-416):
To develop abatement alternatives for reducing odor and volitile organic compounds (VOC) emissions from animal feeding operations.


1b.Approach (from AD-416):
Manure additives including enzymes of horseradish peroxidase (HRP) and soybean peroxidase (SBP) will be added to wastewater from swine and beef feeding lagoons at varying hydrogen peroxide concentrations. Headspace samples will be analyzed for VOC and greenhouse gas concentrations. VOC and greenhouse gas emission rates and treatment effectiveness will be quantified and reported.


3.Progress Report:

ARS scientists at Clay Center, Nebraska and scientists with Iowa State University, Ames, Iowa conducted a laboratory study to determine the optimum application rate of soybean peroxidase plus two different peroxide additives for reducing odors from swine manure. A series of experiments were conducted to determine the optimum rates of the additives. Once the optimum rates of the additive were determined, a final experiment was conducted to compare the effectiveness of the additives for reducing odors.
