Global plastic production and its accumulation in landfills have increased over the years due to the wide applications of plastic in commercial units. The methods of recycling and energy recovery have been some of the alternatives that have been developed for the management of plastic waste. The paper aims to solve the problem of getting rid of plastic waste in safe and environmentally friendly ways, as well as exploiting it to obtain a source of energy. The pyrolysis technique was used using an operative catalyst. A reactor was designed with a thermal heat source and the oil condensation was done on a water container. Factors affecting biodiesel production yield are studied, including the amount of catalyst used, temperature, and reaction time. The physicochemical properties of the biodiesel produced were determined, such as the density by using the Anton Paar Density device method (ASTM D4052), the flash point by using the Stanhope-Seta Flash Point Tester device method (ASTM D93), and the pour point by using the HK-3535 Pour Point Tester device method (ASTM D97). At the optimum conditions of the experiment, it was achieved the highest yield of 57%wt/wt with a conversion rate of 98% at 1:100%wt of catalyst to the raw material at a temperature of 275°C, where the process takes 80 minutes. The liquid product had been found to be feasible as diesel fuel.
