Abstract
Ensuring a clean and secure environment has consistently presented a difficulty for researchers worldwide. In order to accomplish this objective, attention has been drawn to biofuels. The current study investigates the synthesis of biodiesel from stimulated composite sludge. A transesterification method was developed by examining the effects of process variables including preheating temperature, reaction time, methanol-to-oil ratio and catalyst concentration in order to estimate the lowest feasible viscosity and maximum ester recovery. The optimum kinematic viscosity (3.4 cSt) with ester recovery (78.93 %) was obtained by preheating dairy waste sludge at a 5:1 molar ratio to 40 °C and keeping that temperature for 40 min in the existence of 1 % KOH. These findings were based on the measurements of biofuel recovery and kinematic viscosity.
