“…Generally the feedstock used for biodiesel production is edible oil which makes its more expensive than petroleum diesel and not competitive. It is reported that approximately 70%-85% of the total biodiesel production cost arises from the cost of the raw material [13]. Everywhere in the world, there are huge amount of waste oil generated from food canteen, food processing industries and fast food restaurants, if all these wastes are discharged into the environment it will result into environmental degradation and pollution [14].…”

In this research work, the optimum process variables (catalyst, methanol to oil ratio and reaction time) for transesterification of palm oil sludge (POS) to biodiesel were studied. The transesterification process was carried by mixture of palm oil sludge, methanol and catalyst with the help of magnetic stirrer at 300 rpm and at temperature of 60ºC. The catalyst used for the process was potassium hydroxide (KOH). One-Factor-at-A-Time was used to select the possible optimum levels of process variable that gives high biodiesel yield. The study was evaluated by five levels of methanol-to-oil ratio (1:1 -12:1), catalyst (0.1-2%) and reaction time (30 -150 min).The optimum process variables for transesterification of palm oil sludge (POS) to achieved maximum biodiesel yield were found to be methanol to oil molar ratio of 12:1, catalyst loading of 1.5wt% and reaction time of 30 min. At this optimum conditions the maximum biodiesel yield was 61.2%. The biodiesel produced from transesterification of palm oil sludge was characterized in order to determine the Aworanti et al.; BJI, 23(2): 1-14, 2019; Article no.BJI.48733 2 properties of the product. The density of POS is 857.0 kg/m 3 , kinematic viscosity of 5.38 mm 2 /s, flash point of 180°C, pour point of -5°C, and Acid value of 0.17 mgKOH/g. The biodiesel produced from transesterification of palm oil sludge meets the EN 14214 and ASTM 6751 standard. Thus, this study will be helpful to determine an efficient and economical procedure for biodiesel production from non-edible raw materials with high free fatty acid. Original Research Article
