Abstract	A simple pyrolysis of HDPE plastic wastes has been carried out in order to obtain alter-native liquid fuel. About 900 g of plastic was pyrolyzed at constant temperatures varied from 450 o C, 500 o C, 550 o C, 600 o C and 650 o C, The gases were condensed in two consecutive liquid containers separated by a water-cooled condenser. The liquid yield rates were observed and concluded that higher temperature delivered higher rate, between 1.1 ml/min and 5.05 ml/min. Higher temperature produced more liquid in the first container but less in the second container. Several physical characteristics of the liquid were investigated, such as specific gravity. Distillation and GC-MS tests have been conducted to those oils. All products in the second container contained light fractions of hydrocarbons (between C5 and C15), thus almost similar to gasoline. Meanwhile those in the first container contained heavier fractions (between C15 and C24), except pyrolysis at 450 o C, therefore they were closer to diesel fuel. A simple calculation of energy balance was done, where the pyrolysis at 550 o C seemed to be the best, because the generated thermal energy from pyrolytic oil was already higher than the required electric energy for pyrolysis. However several improvements must always be made in order to save more energy and to bring the results into commercialization.
