Abstract:
The present rate of economic growth is unsustainable without saving of fossil energy like
crude oil, natural gas, or coal. There are many alternatives to fossil energy such as biomass,
hydropower, and wind energy. Also, suitable waste management strategy is another important
aspect. Development and modernization have brought about a huge increase in the production
of all kinds of commodities, which indirectly generate waste. Plastics have been one of the
materials because of their wide range of applications due to versatility and relatively low
cost. Recycling can be divided into four categories: primary, secondary, tertiary, and
quaternary. As calorific value of the plastics is comparable to that of fuel, so production of
fuel would be a better alternative. So the methods of converting plastic into fuel, specially
pyrolysis and catalytic degradation, are discussed in detail and a brief idea about the
gasification is also included. Thus conversion of plastic waste into fuel can address the
problem of plastic waste disposal and shortage of conventional fuel and thereby help in
promotion of sustainable environment
