Abstract:
This study aims to produce fuel from plastic waste and determine the physical properties of the fuel. Plastic waste used is mineral water bottles (polypropylene/PP) and plastic bags (low-density polyethylene/LDPE). The method used is an experimental method using pyrolysis. 1 kg of raw material is chopped before being put into the pyrolysis container. The container is then heated and turns the plastic into a liquid and then evaporates. The hot plastic vapor flows into a heat exchanger to be condensed. The cooling process uses water with a counter flow direction of the steam flow. The results of the steam condensation process are then analyzed for their physical properties. The fuel obtained from 1 kg of raw materials is 0.863-0.908 kg, with a density of 742 – 761 kg/m3. The kinematic viscosity of the fuel is between 1.75-1.93 cSt. Flash points 1-2 oC and fire points 8-9 oC with HHV of 44.6-46 MJ/kg. The volume of fuel from plastic bottles of mineral water is more and has a higher calorific value when compared to the fuel from plastic bags waste.
