<p><P>PROBLEM TO BE SOLVED: To effectively recycle a lipid-containing waste discharged from a process for purifying a base oil in an edible oil production plant, to obtain a material for controlling soil disease damage, useful as an industrial material having a controlling effect on soil disease damage and to provide a method and a system for recycling a lipid-containing waste. <P>SOLUTION: The material for controlling soil disease damage is obtained by fermenting a mixture of a lipid-containing waste discharged from a process for purifying a base oil in an edible oil production plant, cow manure and a spreading material of cow barn. In the fermentation, a raw material comprising at least the lipid-containing waste and cow manure is fermented by a fermentation apparatus, a part of the fermented raw material is mixed into the spreading material of cow barn, cows are raised in the cow barn for a fixed period of time. The mixture of the spreading material, cow manure and the lipid-containing waste collected from the cow barn in which cows are raised is re-supplied to the fermentation apparatus and fermented. The material for controlling soil disease damage contains≥1.0×10<SP>6</SP>/g Bacillus subtilis without adding microbial cells from the outside. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
