Abstract

The purpose of this project was to quantify the odor and gas emission benefits of a fine ground rubber cover on laboratory scale manure storage units and to evaluate the ability of a fine ground rubber cover applied to a commercial swine manure storage unit to remain intact and functional over an extended period of time. A three-inch cover of fine ground rubber reduced odors by 77 to 99 percent from the manure storage tanks over a six-week period. However, consistent reductions of NH₃ emissions were not observed and H₂S emissions from all manure storage treatments were below detectable limits. Assessments of the integrity of the fine ground rubber cover were promising for storage units in both the laboratory and field-scale trials.
