“…According to Dias (2013), Juniper (2009), and Nascimento (2011), WCO can be valued in the manufacture of products in various segments of the industry, such as the production of soap, oil paints, and biofuels. Through the valorization of WCO, the production of biofuels appears as a solution to the energy problem to reduce the amount of waste generated and irregular deposition [17,20,21].…”

Turning Waste Cooking Oils into Biofuels—Valorization Technologies: A Review

et al. 2021

In search of a more sustainable society, humanity has been looking to reduce the environmental impacts caused by its various activities. The energy sector corresponds to one of the most impactful activities since most energies produced come from fossil fuels, such as oil and coal, which are finite resources. Moreover, their inherent processes to convert energy into electricity emit various pollutants, which are responsible for global warming, eutrophication, and acidification of soil and marine environments. Biofuels are one of the alternatives to fossil fuels, and the raw material used for their production includes vegetable oils, wood and agricultural waste, municipal waste, and waste cooking oils (WCOs). The conventional route for WCO valorization is the production of biodiesel, which, as all recovery technologies, presents advantages and disadvantages that must be explored from a technical and economic perspective. Despite its successful use in the production of biodiesel, it should be noticed that there are other approaches to use WCO. Among them, thermochemical technologies can be applied to produce alternative fuels through cracking or hydrocracking, pyrolysis, and gasification processes. For each technology, the best conditions were identified, and finally, projects and companies that work with this type of technology and use WCO were identified.
