Abstract

The significant increase experienced by the biodiesel industry also brings with it the concomitant increase in the amount of glycerol as a by-product. In this sense, in order to avoid future problems arising from this accumulation, but also to make the production of biodiesel more competitive, it is necessary to seek economically viable solutions for the use of this by-product for applications in Brazil or even in the international market. In this context, the technological trends related to glycerol oxidation were carried out through the mapping of patents in different databases: INPI, European Patent Office (EPO), United States Patent and Trademark Office (USPTO), The World Intellectual Property Organization (WIPO) and revealed that there is a technological interest in the development of technology as well as found that the number of patents related to the use of electrochemical methods for the oxidation of glycerol is still little explored, consisting of opportunities for research and development with the potential to generate innovation.
