This gas and odor reduction technology, Rapp Technology, consists of an oil cover and a neutralizer that is an alkaline solution. The laboratory study in swine manure reactors to simulate deep manure pit demonstrated statistically significant reductions of ammonia, carbon dioxide, sulfur dioxide, and odor from the treated reactors. Compared with previously tested commercial manure additives, this technology is more effective in mitigating gas and odor emissions from simulated deep manure pits.
During the lab test, the oil and the neutralizer (both by Custom Formulating & Blending, Bristol, IN) cost $1.13 and $ 0.67 per reactor, respectively. According to Juergens Environmental Control (Carroll, Iowa) for field application of the neutralizer, the fixed cost of the system for 1000 to 8000-pig finishing operations averages $2.50 - $5.00 per pig per 3-year term (shipping and labor not included). The cost of neutralizer operation averages $ 0.01 per pig per day over one year.
