heal.abstract	The attendance of biodiesel (fatty acid methyl ester) in Greek and European energy balance is considerable strengthened in the last decade. In our days, biodiesel production is worldwide based on vegetable oils like soy bean oil, rapeseed oil and sunflower oil. However, biodiesel production is a fairly expensive process with its feedstock comprising the major cost. For this reason the investigation for new low cost competitive feedstock is important. Waste tallow utilization has also the advantage that does not compete with the food supply chain and has a higher sustainability rating due to waste recycling. The aim of this study was to demonstrate the utilization of animal fats from Greek slaughter residues and meat processing units as a potential low cost alternative feedstock for biodiesel production. The main objective of this research was to assess the base catalyzed processes to produce biodiesel using waste tallow. The tallow oil was purified in order to reduce the free fatty acids (FFAs) and water content. The dehydration was carried out under vacuum, while acid esterification process with sulfuric acid (H2SO4) as catalyst was applied for the reduction of FFAs content. The transesterification reactions for FAME production were carried out at 65°C with anhydrous methanol in various methanol-to-oil molar ratios (from 6:1 to 15:1), using sodium hydroxide (NaOH) as catalyst in concentrations from 0.5%, up to 3% w/w .Optimum reaction conditions were examined and the quality and properties of the biodiesel product were evaluated through determination of the parameters according to EN 14214 European Standard.	en
