PURPOSE: A manufacturing method of fatty acid methyl ester is provided to manufacture fatty acid methyl ester capable of being used as biodiesel by using oil fraction separated from food waste leachate. CONSTITUTION: A manufacturing method of fatty acid methyl ester comprises: a step of preparing oil fraction separated from food waste leachate; a step of esterification of the oil fraction and alcohol under the presence of a first catalyst; a step of trans-esterification of the residual oil fraction and alcohol under the presence of a second catalyst. The first catalyst is one or more selected from amberlyst 15, amberlyst BD20, WO3/ZrO2, WO3/Al2O3, WO3/SiO2, SO4^(2-)/ZrO2, SO4^(2-)/Al2O3, SO4^(2-)/SiO2, sulfuric acid and zeolite. |
