Effect of in situ composting on reducing offensive odors and volatile organic compounds in swineries

Seven swine farms were studied to find out how the in situ composting system compared to the slatted floor pit system, influences the concentration and occurrence of malodorus compounds. Small molecular sulfur compounds were analyzed using laminated bags and a gas chromatography/mass spectrometry wi...

More Information
Summary:Seven swine farms were studied to find out how the in situ composting system compared to the slatted floor pit system, influences the concentration and occurrence of malodorus compounds. Small molecular sulfur compounds were analyzed using laminated bags and a gas chromatography/mass spectrometry with simultaneous sniffing of the eluted compounds. About 400 organic compounds were identified from the air samples, and 94 suspect odorous compounds are listed. In swine confinement buildings where the composting system was functioning properly, the concentration of sulfur compounds, and especially of carboxylic acids, ketones, and p-cresol, fell effectively. The use of sawdust as composting material caused elevated concentrations of terpenes in the ambient air. There was clearly less airborne ammonia and hydrogen sulfide in the well-functioning compost swineries than in the poorly functioning ones
