METHOD FOR MANUFACTURING LIQUID FERTILIZER FROM ORGANIC WASTES

摘要

PROBLEM TO BE SOLVED: To provide a method for manufacturing a liquid fertilizer from organic wastes which securely and efficiently removes heavy metals and realizes cost reduction and constant quality of the liquid fertilizer which is a recycled product.

SOLUTION: The liquid fertilizer is manufactured by mixing and stirring the organic wastes with a plant-derived material and cooking them at an elevated temperature under a high pressure to separate a liquid matter composing the liquid fertilizer from a non-decomposed solid carbonized matter derived from the plant-derived material. Here, the heavy metals contained in the organic wastes are adsorbed and removed by the non-decomposed solid carbonized matter.
