ABSTRACT
Plastic have become an integral part of our lives. Since plastics are relatively low cost and being easily available have brought a use and throw away culture. Each year more than 100 million tones of plastics are produced worldwide because of use and throw culture so plastics waste management has become a problem worldwide.
In this paper, the process of converting waste plastic into value added fuels are explained which a solution for recycling of plastics become. Thus two universal problems such as
Problems of waste plastic.
Problems of fuel shortage are being tackled simultaneously.
The waste plastics are subjected to depolymerisation, fractional distillations to obtain different value added fuels such as petrol, kerosene, and diesel, lube oil, furnace oil traction and coke.
The process of waste plastic into fuels can literally change the economic scenario of our country. Thus, the process of converting plastics to fuel has now turned the problems into an opportunity to make wealth from waste.
INTRODUCTION:
Plastics play an important role in day-today life, as in certain application they have an edge over conventional materials. Indeed, their light weight, durability, energy efficiency, coupled with a faster rate of production and more design flexibility, have allowed breakthroughs in fields ranging from non-conventional energy, to horticulture and irrigation, water-purification systems and even space flight.
How ever one has to accept that virtues and vices co-exist. Plastics are relatively cheaper and being easily available has brought about use and throwaway culture. Plastics waste management has become a problem world over because of their non-degradable property. A majority of landfills, allotted for plastic waste disposal, are approaching their full capacity. Thus recycling is becoming increasingly necessary.
PROCESS TECHNOLOGY:
Several processes and means have been attempted to fight against the alarming levels of waste generation. However each process had its drawbacks and operational, economical and financial limitations for practical implementation. We have to set up a process to overcome the above-mentioned drawbacks and limitations.
ADDITIVES:
Regular fuels obtained from crude oil like gasoline and diesel are subjected to many reactions and various additives are added to improve combustion and meet BIS characteristics before it is introduced to market. However the fuel (Gasoline, Diesel) fractions obtained in the process can be utilized without much processing.
CONCLUSION:
Since, the plastics are non-biodegradable, the development in biodegradable plastics are still lagging behind. So it is essential to convert the plastics for some useful purposes in order to reduce the waste plastics to environment. . Thus, the process of converting plastics to fuel has now turned the problems into an opportunity to make wealth from waste.
This paper is of greater importance in the present Indian scene in view of the serious energy crisis and is in the interest of national economy.
