Conversion of plastic waste to fuel
Abstract Plastic waste generation has progressively increased over the past 30 years. The recycling techniques of waste plastics presently used include and filling, incineration, chemical or mechanical recycling, and conversion to fuel. There are a number of conversion techniques presently used; they include thermal pyrolysis, catalytic pyrolysis, copyrolysis and gasification. The techniques used depend on types of plastic waste. The fuel oils from waste plastics have properties (calorific valve, density, and viscosity) which are better or equal to that of commercial diesel fuel. The conversion of plastic waste into fuel helps to resolve two important problems: one is avoiding the negative impacts of plastic pollution on the environment and the second is to produce an alternative fuel for diesel engines, thus reducing the demand on fossil fuels.
