Utilization of Breed Chicken Eggshells to Make Biodiesel from Waste Cooking Oil

Chicken eggshell waste is a potential source of CaO which can be converted into heterogeneous catalysts.  The purpose of this study was to utilize CaO heterogeneous catalysts to make biodiesel from waste cooking oil through the process of transesterification. A total of 4 g of catalyst was mixed with 200 g of waste cooking oil and 60 g of methanol, stirred at a speed of 700 rpm for 6 hours at a temperature of 600C ± 40C. The results were analyzed using GC-MS to confirm the formation of various methyl ester compounds.  The product was found to have a density of 855 Kg/m3., viscosity of 3.74 mm2/s (cSt), and flash point of 1350C Based on the results, it be concluded that breed chicken eggshells can be converted as catalysts heterogeneous to make biodiesel from waste cooking oil. This information is very useful for further optimization of mass catalysts heterogeneous CaO from breed chicken eggshells including the production of biodiesel.
