Effect of aeration on greenhouse gas emission from the composting process of swine manure

　　The purpose of this study was to evaluate the effect of aeration condition on the greenhouse gas (GHG) mission from the composting process of swine manure. The swine manure was piled in the composting plant X, Y and Z with 3, 0.5 and 0 min/hr of aeration, respectively. The results of this study showed aeration during the compost process can accelerate the degradation of organic matters, shorten the period of composting, and reduce the production of methane from the compost.
