Download PDFPlastic waste component of the urban solid waste is quite problematic. As it is non-biodegradable it can stay in the environment for a longer time causing severe environmental degradation. Recycling of plastics is seen as one method for reducing environmental and resource depletion. Pyrolysis is one of the most versatile process which convert plastic materials into smaller molecules usually liquids or gases which are suitable for use of new petrochemical product and have proven to useful in production of fuel. Pyrolysis involves the degradation of the polymeric materials by heating in the absence of oxygen. This study investigated the characteristics of pyrolysis liquid fuel produced from polypropylene plastic waste for different temperatures. Pyrolysis was carried put on 400 grams of polypropylene plastic waste at the operating temperature of 230°C, 280°C , 330°C , 380°C , 430°C , 480°C for one hour. The liquid products were found to have carbon chain length in the range of C8-C9 , similar with gasoline. The maximum density, volume and calorific value of the oil obtained were 0.82 gm/cc, 85 ml and 1650 Cal/gm respectively. Depletion of non-renewable source of energy such as fossil fuel at this stage demands the improvements of the chemical recycling technique. Based on the properties of the plastic fuel and diesel fuel all the properties are nearly same , so the waste plastic fuel represents a good alternative fuel for diesel engine.
