The main reason was caused by infection from kitchen waste, and the root cause was the existing Food waste treatment methods are not well sterilized and produced in a standardized manner; in addition, food waste can also be used as organic fertilizers, but if they are used as organic fertilizers without treatment, there are difficulties in storage and transportation. The inventor designed an ideal and environmentally friendly method for producing organic fertilizers from kitchen waste
