Description
Summary:The current waste management trends in urban areas are caused by changes in social, economic, political, and cultural life. As a non-biodegradable polymer, plastic waste has created a very serious environmental challenge because of its large numbers and disposal problems. Plastic recycling is seen as one of the methods to reduce environmental pollution and resources depletion. The most interesting plastic recycling technique is pyrolysis which involves the degradation of polymeric materials with heating without oxygen. This study investigates the characteristics of liquid fuel pyrolysis (PLF) generated from polypropylene plastic waste with temperature variations. Pyrolysis was performed on 200 grams of polypropylene plastic wastes at operating temperatures of 200 °C, 250 °C, 300 °C, and 350 °C for 45 minutes. The maximum density, volume and calorific values of the oils obtained were 0.8 g/cm3, 61 ml, and 1307 Cal/gr, respectively. The pyrolysis process shows an inverse ratio between the solid (char) and liquid (oil) product, the fraction contained in the oil having the C8-C12 hydrocarbon bond range, equals the gasoline.
