Finding adequate non-food sources is one of the main challenges while producing biofuels. Particularly for biodiesel, research is focused on using unconventional crops, residues, and wastewith high fat and oil contents. Furthermore, spent coffee grounds contain a proper fat ratio and arecommercial and domestic waste materials. Therefore, this study assesses biodiesel production using fats extracted from coffee grounds through a two-stage process. The fats extracted from coffeegrounds by boiling at reflux using hexane as a solvent presented high acidity at 32.07 ± 0.01% (70.24± 0.03 mg KOH/g fat), thereby indicating a high content of free fatty acids (FFA). First, the fats wereesterifed at 60 °C and 100 rpm using different reaction conditions. Th...
