Abstract
Recycling waste frying oils is an important issue concerning environmental and economic problems. Biodiesel production from waste oil is an effective method to obtain a sustainable energy source. Biodiesel attracts attention as a renewable and environmentally friendly alternative that can replace traditional fossil fuels in diesel engines. However, various process parameters such as process temperature, alcohol/oil ratio, and type of catalyst need to be carefully adjusted to increase the efficiency and optimize the quality of the biodiesel production process from waste oils. This study uses the Taguchi method to determine the most suitable process parameters for experimental biodiesel production from waste oils. The study's findings, which identified the optimum conditions for biodiesel production from waste frying oil, have the potential to impact the field of sustainable energy significantly. Three essential parameters were selected for investigation: the molar ratio of alcohol to oil, reaction temperature, and reaction time. Each parameter was examined at two levels, denoted as L-4 (23). Four experimental runs were conducted using the selected parameters and their respective levels to produce biodiesel from waste frying oil. Optimum conditions were found to be 1:6 for oil/methanol molar ratio, 60°C for reaction temperature, and 60 min for reaction time. Under optimum reaction conditions, biodiesel yield was an average of 97.7 %.
