METHOD FOR PREPARATION OF ORGANIC FERTILIZER BY HYDROLYSIS AND FERMENTATION OF WASTE HUMAN HAIR

摘要

PURPOSE: An organic fertilizer composition produced by the waste hair hydrolysis and the microbial fermentation, and a producing method thereof are provided to prevent the environmental contamination caused by burying or combusting waste hair. CONSTITUTION: A producing method of an organic fertilizer composition comprises the following steps: contacting waste hair with an alkaline solution for obtaining a waste hair hydrolysis alkali solution; neutralizing the waste hair hydrolysis alkali solution for obtaining a waste hair hydrolysis neutralized solution; and inserting microorganisms into the neutralized solution for fermenting. The alkali solution is obtained by mixing sodium hydroxide, potassium hydroxide, and calcium hydroxide, and dissolving the mixture in water.
