Bio based grease A value added product from renewable resources

Finite resources of crude petroleum oil and growing concern over climate change are driving investment and innovation in the sector of biofuels. Vegetable oils in comparison with mineral oils are renewable, easily available, environmentally friendly, economically cheaper than mineral oil and hence sustainable indeed. This paper presents a series of structural modifications of vegetable oil-Karanja oil using various alcohols to form fatty acid esters. This fatty acid esters were then used as base oil in the formulation of grease. Formulated bio-based grease was then evaluated for its tribological properties against mineral oil based grease.
