The Feasibility of Waste Workshop Oil for the Formulation Lubricating Grease with-Bio Thickener for Industrial Usage

Environmental concerns have prompted industry to seek alternate green options for lubricating grease formulation. The key problems in generating modified grease include taking into account the chosen thickener as an environmentally friendly material. According to studies, waste oil can be utilized as grease base oil; nevertheless, the variety of waste oil compositions at every disposal influence grease formulation. The current study's main objectives were to formulate lubricating grease utilizing waste motor oil as base oils and to investigate the influence of thickener on the formulated lubricant grease. The base oils were made from filtered and unfiltered waste motor oil obtained from a workshop., beeswax and natural molybdenum disulfide (MoS2) were used as thickener and additives. The grease's physiochemical characteristics were determined and compared to industry standards. The grease was evaluated for consistency, stability, and oil bleeding. Except for the grease containing unfiltered used oil, the prepared greases had a grease consistency of grade 2. Grease modification using an environmentally friendly thickening was successful, although it is regarded a low temperature grease due to the low melting point of beeswax (62°C-65°C).
