1. A method for producing a long-chain fatty acid, the method comprising:
(a) decomposing triglyceride contained in a raw vegetable oil into fatty acids using a lipase, wherein the raw vegetable oil is obtained from vegetable waste comprising oil;
(b) after (a), removing a short-chain fatty acid contained in the raw vegetable oil by distillation; and
(c) after (b), recovering a long-chain fatty acid contained in the raw vegetable oil by short-path distillation,
wherein the long-chain fatty acid has at least 9 carbon atoms, and the short-chain fatty acid has 8 or less carbon atoms.
