Recycling is an effective technology for minimization of process cost. Recycling of biocatalyst along with recycling of used oil is a new technique for the preparation of alternative fuel Preparation of alternative fuel through cost minimization is supposed to be the most challenging job in the present academicians and researchers. Biodiesel is one of the most important alternative fuels in the near future and it attracts considerable attention as environment friendly, renewable and non-toxic fuel. In the present research investigation, waste cooking oil (WCO) is utilized as cheap raw materials for this purpose and enzyme recycling technology has been adopted to prepare biodiesel. Recycling of enzyme is a novel technology which can reduce the process cost. In our study, nonspecific enzyme Novozyme 435 (Candida antarctica) is utilized and recycled ten times for the transesterification reaction of WCO and methanol maintaining definite reaction parameters like alcohol to oil molar ratio, reaction temperature, mixing intensity and biocatalyst concentration. The physical properties of WCO methyl ester and diesel fuel have been compared and it shows significant results. So recycling of enzyme for the production of alternative fuel from recycled oil can be utilized to mitigate scarcity of non-renewable fuel in the future world.
