The underutilization of plastic waste leads to environmental and health degradation. Utilizing plastic waste as an alternative fuel through pyrolysis is a precise choice for reducing waste quantity and improving environmental quality. This study aims to determine the effect of temperature and pyrolysis time of low-density polyethene (LDPE) plastic waste on the quality of pyrolysis oil. A laboratory-scale fixed batch reactor set to three temperature variations of 520, 550, and 580°C with processing times of 90 and 120 min was used to produce pyrolysis oil from plastic waste. The results showed that to produce more than 55% of pyrolysis yield, it is necessary to increase the processing time by 30 minutes at a temperature of 520°C. Increasing the process temperature to 580°C increased the density and viscosity of pyrolysis oil to 823 kg/m³ and 20 cSt, respectively. However, the calorific value will decrease by 4 MJ/kg; it is mixed with other biofuel products to reduce its viscosity value.
