A Comparative Study between Biodiesel Produced Fromwaste Cooking OIL, Microalgae and Waste Plastic.

Biodiesel production has increased over the last few decades and has received considerable attention. Biodiesel is composed of renewable materials emitting less greenhouse gas compared to petroleum diesel. Biodiesel is an alternative fuel that is acquired from renewable energy sources. The exploration of new methods for biodiesel production has become a key area of research interest. The raw materials used are waste cooking oil, microalgae, and waste plastic material. Direct use and blending, micro emulsions, thermal cracking (pyrolysis), and transesterification are the four primary methods for producing biodiesel. Among these four primary methods, transesterification is the most commonly used method for the production of biodiesel from waste cooking oil and microalgae and for waste plastic pyrolysis is used. Waste cooking oil was collected from local restaurants and food stores, microalgae were collected from local ponds, and plastic waste was collected from local garbage collectors. The reactant used for biodiesel production from waste cooking oil, microalgae, and waste plastic are hexane, and methanol, and the base catalyst used was sodium hydroxide. The characteristic properties of the produced biodiesel like viscosity, pour point, Flashpoint, Density, Acidic value, Calorific value, etc. were studied using various lab equipment. Using these parameters, the comparative paper was written for Biodiesel production from waste cooking oil, microalgae, and waste plastic.
