Evaluation of additive for reducing gaseous emissions from swine waste CIGR Journal
Sanjay B. Shah; NC State University; Praveen Kolar; Biological and Agricultural Engineering Department, North Carolina State University, Raleigh, NC 27695, USA.
Additives can reduce gaseous emissions from swine waste lagoons and pits.  We have demonstrated for the first time that an additive has the potential to reduce methane emission from an anaerobic swine lagoon.  ManureMax®, a humate product was evaluated for its ability to reduce gas and odor emissions from swine anaerobic lagoon and barn flush-water.  Four treatments, Control (no additive), Low (label dosage), Medium (50% higher than label dosage), and High (200% higher than label dosage) were applied to inclined pipes installed in a swine lagoon.  While the Medium and High treatments were not effective, the Low treatment reduced methane, 2-butanone, and tetrahydrofuran concentrations by 34%, 44%, and 57%, respectively vs. the Control in the pipe headspace....
