Meanwhile, the moisture content, pH, germination, TC, TN, and C/N all reached the standard condition of fermentation. 　　On the other hand, since much of dust would be produced during the composting process, the control strategy for fans had been designed to regulate the air flow in order to eliminate the problem of air pollution.
