To develop technology for deodorizing swine manure facility, which odor raises a number of complaints, the volatile compound of swine manure in the facility was investigated using gas-chromatograph and gaschromatograph mass spectrometry. Ammonia, trimethyl amine, sulphide, volatile fatty acids, phenols and indoles were detected in the swine manure. The detected odor components were remarkably decreased in swine manure added with maturated compost. After swine manure was piled in an aeration chamber for 15 days, the concentrations of ammonia, trimethyl amine, methanethiol, dimethyl sulfide, dimethyl disulfide decreased. Therefore, it is most important that swine manure is mixed with maturated compost and aerated immediately to deodorize the facility.
