The high production of glycerol, a low-cost by-product, from the biodiesel industry, has posed a threat to both the environment and the economy. The transformation of glycerol into value-added products would contribute positively to the biodiesel economy. In this review article, the valorization routes of glycerol are described; esterification is presented as one of the most promising routes for the transformation of glycerol in additive fuels. This review describes the most relevant results between 2010 and 2020 related to experimental conditions (temperature, molar ratio, and reaction time), heterogeneous catalysts, and catalytic activity (in terms of glycerol conversion and acetins selectivity) for the transformation of glycerol into acetins. (monoacetin, diacetin and triacetin). It is hoped that this review will allow this valuation technique to be addressed in a profitable and environmentally sustainable manner
