However, these microbial composting accelerators require a considerable amount of time for the completion of composting, since the rate of microbial changes due to temperature increase is not rapid due to the uncontrolled proportion of low temperature, mesophilic and high temperature microorganisms. No microorganisms were excluded. In addition, when the composting conditions are not appropriate, anaerobic fermentation occurs, odors and leachate are generated in a large amount, and problems such as difficult decomposition of cellulose, lignin, and collagen have been exposed. Therefore, there has been a constant need to develop microbial composting accelerators that can shorten the time required for composting by improving these shortcomings, easily decompose difficult-decomposable waste and minimize the possibility of anaerobic fermentation.

After all, the main object of the present invention is to solve these problems of the prior art, as well as the moisture control agent used to control the water content of the waste, in addition to the sawdust, chaff mainly used in the existing method bark, soybean rice and bakmul etc. It can be used to provide an economical microbial composting accelerator.
