Utilization of Polypropylene (PP) Plastic Waste to Fuel Oil by the Pyrolysis

Abstract

The increasing number of residents causes an increase in the volume of waste, especially plastic waste. Pyrolysis is the process of breaking down complex polymer structures to become simpler through a thermal (heating burning) process without using oxygen. Liquid smoke can also mean the result of cooling and melting smoke from biomass material that is burned in a closed tube. This study aims to determine the processing of unused Ploypropyline plastic waste into alternative fuels by pyrolysis process. The pyrolysis process was carried out at the reactor for 5 hours with 500 grams of waste producing 160 mL. The results showed that the density of pyrolysis oil was 0,812 g/ml. The time needed to burn out an object is 5,28 minutes. Heating water using pyrolysis oil produces a temperature of 78oC at 5 minutes heating time with a volume of water lost (evaporating) of 4,8 ml. Of the four parameters that have been observed, the quality of pyrolysis oil is between premium oil and kerosene.
