Characteristics physical and chemical properties of fuel from plastic waste for mineral water glasses

Abstract

This research aims to convert plastic waste, especially plastic cups for packaging mineral water, into fuel oil through a pyrolysis process. The experimental method used is with the following stages: first, 1kg of plastic raw material is chopped before being put into a pyrolysis tube. Next, the tube is heated to change the plastic into a liquid form which then evaporates. The hot steam from this plastic is channeled to a heat exchanger to be condensed. Cooling is carried out using water flowing in the opposite direction to the direction of the steam. The results of plastic vapor condensation are collected to analyze their physical and chemical properties. Testing of physical and chemical properties includes specific gravity, heating value, kinematic viscosity, flash point, ash, lead and sulfur content. The result is that fuel from plastic bottle waste has a density value of 742 kg/m3, kinematic viscosity of 1.76 cSt, lower heating value of 43.28 MJ/kg, flash point of 1OC, ash, lead and sulfur content respectively of 0.003905%, 0.0000231%, and 0.000462%.
