Abstract

This research explores the development of biolubricants derived from used cooking oil as a solution to reduce dependence on petroleum-based lubricants, which have adverse environmental effects. Used cooking oil was chosen for its abundant availability, low cost, and potential to be converted into biolubricants through esterification and transesterification processes. This study employed a double transesterification method using CaO as a catalyst, with catalyst concentrations varied at 1%, 2%, and 3% to produce biolubricants. Results indicated that a 2% catalyst concentration provided the best performance in terms of viscosity, density, viscosity index, and flash point. The resulting biolubricant products were classified within ISO VG 10 and ISO VG 15, meeting the standards of commercially available industrial lubricants. These biolubricants are expected to serve as environmentally friendly alternatives with potential applications in various machinery requiring specific lubricant properties.
