Method & Evidence

AimCan waste frying oil be effectively converted into lubricating greases that exhibit performance characteristics comparable to conventional petroleum-based greases?
MethodExperimental characterization and performance testing
ProcedureLubricating greases were prepared using waste sunflower and palm frying oils, incorporating calcium/lithium stearate soaps and cellulose or lignin sulfate fillers. The resulting greases underwent rheological characterization, penetration tests (before and after working), dropping point determinations, oil bleeding tests, and mechanical tests to measure friction coefficient, contact resistance, and wear scar diameter.
