The ongoing use of traditional fossil-based fuels has a variety of negative environmental effects, motivating the need to seek out sustainable and environmentally favorable alternatives such as biodiesel. One of the major challenges associated with the biodiesel process is the cost associated with the feedstocks. Thus, there is motivation to seek out alternative and low-cost feedstocks for biodiesel production. Thus, the focus of this work was to assess the potentials of waste vegetable oil (WVO) and Sesamum indicum oil as inexpensive and sustainable feedstocks for biodiesel production. This was done by completely characterizing both oils to determine their key characteristic which indicate their suitability for producing biodiesel. The results showed that free fatty acid content, viscosity, peroxide value, density and saponification value of WVO and Sesamum indicum oil were 2.9 and 1.89 %, 21.4 and 6.40 mm2/s, 2.8 and 3.1 meq O2/g, 971 and 896 kg/m3, and 190 and 174.6 mg KOH/g respectively. These values were comparable with those reported in literature and indicated the suitability of both oil feedstocks for biodiesel production.
