<p>PURPOSE:To provide a production method of a compost which prevents sludge from becoming anaerobic, capable of efficiently producing an aromatic compost, capable of keeping a working environment appropriately and capable of utilizing a waste effectively, moreover, simplifies switching work at a fermentation stage, capable of an automation of a production device, capable of producing in a short time and capable of producing by open-air storage in the open-air. CONSTITUTION:In the production of the compost by fermenting a starting material, a surplus sludge, etc., generated at night soil treatment facility is used as a spawn containing a nitrogen source, a waste food oil is used as a carbon source and a vegetable waste such as rice husks, cutting chips of rice straw, sawdust and wood shavings are used as a permeable functional material and a moisture controlling material, and a mixing ratio of the nitrogen source and the carbon source in the starting material is controlled by using the waste food oil.</p> |
