<p>In a method for manufacturing of organic fertilizers characterized by shearing and kneading a waste containing organic materials or a mixture of said waste with cellulose-containing organic materials under an elevated pressure at a high temperature, releasing them from the state of elevated pressure, followed by pulverizing the treated mixture while contacting it with air, an improvement is proposed which comprises returning a part of the processed mixture discharged from the treating tank and left under the conditions of fermentation by thermophilic microorganisms after discharging, to the treatment tank to recycle and mix the recycled materials with fresh raw materials. By means of recycling a part of the products, a stable operation can be attained in a short time. Therefore a compost of good quality can be obtained in a short time without bad odor. <IMAGE></p> |
