PROBLEM TO BE SOLVED: To efficiently manufacture a ripened compost-like material of high commercial value as an organic fertilizer by a method of manufacturing the ripened compost-like material by heating and drying organic waste and heat-treating it. SOLUTION: In manufacturing the ripened compost-like material by heating and drying the organic waste and heat-treating it, a polymer is added and mixed with the organic waste to increase granulation properties to manufacture the granular ripened compost-like material having excellent handleability. Alternatively, a potassium component is added and mixed in the ripened compost-like material to manufacture the ripened compost-like material having well-balanced fertilizer components of nitrogen, phosphorus and potassium.
