A method for production of diesel biofuel from waste oils comprises filtration processes with isolation of concomitant admixtures, neutralization of free fatty acids, oil washing with saline solution and water, purification from admixtures, and interetherification. Furthermore, the waste oil is used having content of free fatty acids of 5-20 mg KOH/g, and neutralization thereof is carried out by etherification reaction with concentrated sulphuric acid – 1.5 % from the mass during 2 hours at the temperature of 60- at constant stirring with isolation of water and alcohol, wherein methanol and sulphuric acid are taken in molar ratio of 6:1 and directed for interetherification with adding of methanol and the catalyst - KOH.
