These plastic Plastic waste waste samples were collected from household waste and converted into plastic derived oil (PDO) by low tem- Fuel perature (300 °C to 400 °C) slow pyrolysis (long isothermal holding time) in a semi-batch reactor. The PDO Hydrocarbon samples obtained had shown variation in their compositions and fuel properties based on the pyrolysis tem- NMR perature. PDO from the pyrolysis of PP has high octane number ( ∼92) and low viscosity. Noticeably, the PDO samples obtained at low temperature pyrolysis are li
