This article is a review based on literature sources. The production technology and areas of application of bioethanol, as well as ways to intensify the production of alcohol obtained from these natural sources, are analyzed. One such method is biomass liquefaction. Modern technologies for converting biomass into valuable biofuels were studied. Common biomass liquefaction technologies are indirect liquefaction and direct liquefaction. Direct biomass liquefaction involves converting biomass into bio-oil, and the main technologies are hydrolytic fermentation and thermodynamic liquefaction. Based on thermodynamic liquefaction, it can be divided into fast pyrolysis and hydrothermal liquefaction. In addition, this review provides an overview of the physicochemical properties of biodiesel and common methods for its processing. Keywords: bioethanol, yeast, natural food waste, purchasing biofuel.
