The authors introduced plastic pyrolytic oil as an alternative fuel characterized in detail and compared to properties of conventional fuels, such as kerosene and diesel. The mixture of polyethylene and polyprophylene was pyrolyzed in a specialistic reactor to produce oil fuel. The mixture was completely pyrolyzed at 420–450 °C for 2 h to obtain the solid residue, liquid fuel fraction, and gaseous products. A comparison of the obtained fuel properties to the diesel and kerosene fuel standards (ASTM D975 and EN 590) revealed that the synthetic product was within all specifications. Notably, the fuel properties include viscosity at 40 °C of 3.946 cSt, density at 40 °C of 0.809 g cm–3, sulfur content of 0.11 wt %, and high calorific value of 45.7 MJ kg–1, which are very similar to conventional diesel fuel characteristics.
