Biodiesel is a revolutionary step in the world of fuel. The increased demand and high price for energy sources are driving efforts to convert organic compounds into useful hydrocarbon fuel. Biodiesel has become more attractive because of its environmental benefits and the fact that it is made from renewable resources. Biodiesel production is generally carried out through the process of transesterification reaction. The reaction is facilitated with a suitable catalyst. In this work it is made a review of the biodiesel production by alkali transesterification. There is a need to improve the existing biodiesel production methods from both economic and environmental viewpoints and to investigate alternative and innovative production processes. The transesterification kinetics for various catalysts and the emerging technologies which can be utilized in this field are also investigated. The quality of biodiesel produced from waste vegetable oil in previous studies is also reviewed and the performance of engines fueled with this biodiesel and the characteristics of the exhaust emissions resulting from it are investigated. The goal is to stimulate further activities in the field.
