This study covers production of liquid fuel from waste plastics by cracking the waste plastics by means of thermal pyrolysis. The waste plastics used were a mixture of polyethylene terephthalate and polystyrene. Physiochemical properties of the liquid fuel were determined experimentally and then compared with those of petrol. The pour point of liquid fuel and petrol was 1.02°C and −26°C, respectively; the higher heating value of liquid fuel and petrol was 39.5 and 44.18 MJ/kg, respectively; the lower heating value of liquid fuel and petrol was 38.2 and 41.50 MJ/kg, respectively; the fire point of liquid fuel and petrol was 90.20°C and 24°C, respectively; the octane number of liquid fuel and petrol was 46.0 and 93.1, respectively; the kinematic viscosity of liquid fuel and petrol was 2.76 and 0.487 mm 2 /s, respectively; the boiling point of liquid fuel and petrol was 182.40°C and 210.4°C, respectively; the autoignition temperature of liquid fuel and petrol was 230°C and 235°C, respectively. The physiochemical properties of liquid fuel and petrol are not significantly different and, therefore, the liquid fuel could be used as an alternative fuel to petrol.
