Abstract

A method for production of a biodiesel is described herein. The method for production of a biodiesel comprises (a) separating solids from a waste oil composition to provide a clarified oil composition; (b) acidifying the clarified oil composition to produce an acidified oil composition including free fatty acids derived from the waste oil; (c) converting at least a portion of the free fatty acids in the acidified oil composition to glycerides to provide a glyceride composition; and (d) reacting at least a portion of the glycerides in the glyceride composition with methanol to form fatty acid methyl ester to provide a biodiesel composition.
