Titanium dioxide was seen as the solution to put an end to two pressing issues faced globally today, water scarcity and energy shortage. In accordance with the world’s movement towards an energy sustainable world, biodiesel production would become a viable option. However, the disadvantage is the generation of glycerol, a main by-product that contributes 10% by weight for every biodiesel produce. Currently, chemicals such as 1,3-propanediol (Mu, Teng et al. 2006) and oxygenated chemical (fuel additive) (Eva, Miriam et al. 2008) are produced using glycerol as feed through either conventional catalysis or biotransformation processes. However, these processes are not cost-friendly and also due to the inconsistency in the glycerol feed composition the process could not attain its optimum operating efficiency (Yang, Hanna et al. 2012). Hence glycerol was chosen as the target pollutant in this study.
