Generating of Fuel from Waste Plastic

Abstract :

Plastics plays the major role in our day-to-day lives and huge usage of plastic and no proper recycling methods they pose a tremendous threat to the environment. Over a 100 million tonnes of plastics are produced annually worldwide, and the used plastic products have become a common feature at over bins, landfills and also in water bodies too. The plastic waste not only creates the air pollution but also water and soil pollution too. Here, the process of converting waste plastic into value added fuels is explained as a solution for recycling of plastic waste. Hence by this study the two problems are going to solved i.e., waste plastic and fuel shortage. In this study, plastic wastes (low density polyethylene)were used for the pyrolysis to get fuel oil that has the same physical properties as the fuels like petrol, diesel etc.
Pyrolysis runs without oxygen and in high temperature of about 300°C which is why a reactor was used to provide the required temperature for the reaction. The waste plastics are subjected to depolymerisation, pyrolysis, thermal cracking and distillation to obtain different value added fuels such as petrol, kerosene, and diesel, lube oil etc. Thus, the process of converting plastics to fuel has now turned the problems into an opportunity to make wealth from waste. The hazards of plastic waste is well known to us. The conversion of oil from plastic has dual benefits. First of all the oil produced can be used as a fuel for domestic purposes and also in vehicles and industries when further refined. Secondly the various types of pollution caused due to waste plastics can be minimized. Therefore the waste plastic can be converted back into it. For the process of conversion a machine can be used which will heat the plastic to a temperature so that it melts and does not burns.
