NOVELTY - Soil disease suppression material, obtained by fermenting a mixture of lipid containing waste material emitted during purification or deoxidation of crude oil in an edible oil (alkali refined oil) manufacturing plant, and cattle feces/urine and bedding of dairy cow shed in a fermentation apparatus as a raw material, reclosing the mixture of raw material and adding fresh lipid containing base material into the fermentation apparatus and carrying out fermentation.    USE - For obtaining soil disease suppression material using lipid-containing waste material (claimed). The soil disease suppression material is useful for improving soil, for preventing replant failure and suppressing plant disease such as Chinese flat cabbage chlorosis, Brassicaceae vegetable club root, wilt disease of tomato or spinach caused by Fusarium.    ADVANTAGE - The soil disease suppression material can be manufactured economically, using the lipid containing waste material emitted from oil refinery, cattle feces/urine and bedding of cow shed as a raw material. The soil disease suppression material decreases the usage-amount of agrochemical and suppresses the amount of lipid-containing waste material.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following:    (1) a method of deutilizing lipid containing waste material, involves fermenting raw material containing lipid-containing waste material emitted during purification or deoxidation of crude oil in an edible oil (alkali refined oil) manufacturing plant, and cattle feces/urine in a fermentation apparatus, mixing a part of the fermented raw material with the bedding of dairy cow shed, adding cattle feces/urine and bedding of dairy cow shed after a predetermined time of fermentation, and fresh lipid-containing waste material, and carrying out fermentation; and    (2) a system for recycling lipid-containing waste material, comprising a fermentation apparatus for fermenting aerobically, the raw material containing the lipid containing waste material emitted during purification of deoxidation of crude oil in edible oil (alkali refined oil) manufacturing plant, bedding of dairy cow shed and cattle feces/urine.    DESCRIPTION OF DRAWING(S) - The figure is a flowchart representing the manufacturing process of soil disease suppression material. (Drawing includes non-English language text)
