The potential of waste cooking oil as supply for the Brazilian biodiesel chain

Biofuel production stands out on an international level because of its environmentally sustainable characteristics and the potential to promote rural development in developing countries. Introducing waste cooking oil (WCO) into the biodiesel chain holds the potential to promote social inclusion in urban areas in developing countries as well. In this sense, this paper examines the opportunity for biodiesel production from WCO as a potential source for future energy supply, particularly for biodiesel, and in this case, we will analyze the Brazilian scene. Several related aspects are covered, such as the physical and chemical properties of the WCO and the biodiesel made from it. The process of production is also presented. Lastly, the potential of the supply for this chain and the potential of social inclusion in developing countries, especially in Brazil, are analyzed.
