In this study, a novel heterogeneous catalyst was successfully developed from drinking water treatment sludge (WS) which was obtained during defluoridation and used for biodiesel synthesis by transesterification process using mixture of edible and nonedible oils. The sludge was converted into effective catalyst by calcination at 950 °C for 3hr. The catalyst was characterized by X-ray powder diffraction (XRD), Thermogravimetric analysis (TGA), Fourier transform infrared (FTIR), Scanning electron microscopy (SEM) and Hammet titration method. The catalyst showed good catalytic activity with 12.57 mmoles/gm basicity and basic strength of 9.8&lt; H-&lt;17.2 for biodiesel synthesis. The suitable reaction parameters for maximum biodiesel yield up to 85% were methanol to oil molar ratio of 12:1, 4 wt% of catalyst, reaction time of 3 hours and reaction temperature of 68 °C. Thus a harmful waste could be converted and utilized as effective low cost solid base heterogeneous catalyst.
