Abstract

In general lubricating greases contain mineral oil as fluids, which are toxic to the environment after use. On the other hand, waste cooking oil is discarded in sewage, and banana peel is dumped in landfills; this waste has created a negative impact on the environment and economy. Accordingly, the objective of this study is to prepare biogrease from waste cooking oil and banana peel. Purification and improvement of these wastes were carried out respectively; their physical and chemical properties were determined using advanced analytical tools. Also, the kinetic analysis of the thermal degradation of banana peel was obtained from weight loss at temperatures (0-800oC) using model-free, modelistic methods and MATLAB; it showed all the possible mechanisms have a non-isothermal modelistic method. Five formulations from biogreases were prepared based on banana peels and waste cooking oil; the physicochemical properties of this formulation were determined. it was shown that the dropping point and consistency of grease depend on the ratio of banana peels incorporated in the grease formulation. The use of a blend of lithium soap and banana peels as thickeners provides properties comparable to those found in commercial lithium grease. It was concluded that the waste cooking oil and banana peel can offer promising eco-friendly raw materials for the production of biogrease
