METHOD FOR MANUFACTURING ORGANIC MATERIAL, ORGANIC MATERIAL, AND RECYCLING SYSTEM OF USED BEDDING MATERIAL

摘要

PROBLEM TO BE SOLVED: To effectively utilize bedding materials after using, especially excrement of livestock.SOLUTION: A method for manufacturing organic materials includes a decomposition step of decomposing organic substances. The decomposition step is performed by aerobically decomposing the organic substances with lactic acid bacteria which are included in excrement by supplying lactic acid bacteria and breeding livestock. It is preferable to supply lactic acid bacteria to livestock by giving livestock animal feed which is mixed with a solid lactic acid bacterium material of 0.01 volume part-2.0 volume parts based on 100 volume parts of animal feed excluding lactic acid bacteria. It is preferable that the method further includes a fermentation step of anaerobically fermenting used bedding materials used for breeding livestock before performing the decomposition step. The decomposition step is performed by aerobically decomposing the used bedding materials after the fermentation step. The aerobic decomposition is desirably performed under a fine aerobic condition of an oxygen pressure of 10% or less. In the decomposition step, mineral water is preferably sprayed to the organic substances.SELECTED DRAWING: Figure 1
