Abstract: 

Alternative treatments to convert plastic waste into fuel currently receive great attention from researchers worldwide. The objective of the research is to obtain liquid fuel from pyrolysis of waste plastics that is safe for humans as well as environment, with a heating value and fuel quality meet the standardized compliant. The method used for the research is plastic waste pyrolysis heated at 900 °C, and the resulting vapor is condensed through a crossflow condenser. The method resulted in a liquid fuel with a calorific value of 46,848 J/g, which is greater than that of plastic waste processing at a temperature of 425 °C that is only 41,870 J/g. In addition, the
nature of current method for treating plastic waste is considered more secure than that of plastic waste processing at the temperature of 425 °C. The reason for this is the fact that the percentage of compounds that could potentially be carcinogenic (boric acid and cyclopentanone) is reduced.

Key words: Plastic waste, fuel, pyrolysis, green product.
