The substitution of diesel by biodiesel meets the current scenario to increase the consumption of alternative energy sources promoting sustainable development of a country. However, the production of biodiesel concurrently generates the formation of glycerine in the process is a by-product. The main application of glycerine is in the food industry, cosmetics, soaps, pharmaceuticals, among others, but these segments are not capable of absorbing the generated volume of glycerine, whereas the total volume of the biodiesel produced about 10% correspond to glycerine. Glycerine obtained from the transesterification reaction (necessary for production of biodiesel) triglycerides and alcohol contains certain impurities such as water, salts, esters, alcohol, and residual oil, which decrease the value. Thus, the purification process or the direct use of glycerine become essential to make it competitive biodiesel production process. This work aims to evaluate the different processes of purification and the use of glycerine obtained as by-product in the production of biodiesel. The research was theoretical, based on technical articles and theses published on this subject, and from these databases was established a summary of the most important processes
