PYROLYSIS - A PIONEER IN PLASTIC WASTE RECYCLING


ABSTRACT:
The need for efficient plastic waste disposal introduced new technologies for plastic waste treatment. Among the various technologies available, pyrolysis appears to be a technique that is able to reduce a bulky high polluting waste while producing energy and/or valuable chemical compounds.
In this paper, pyrolysis of plastic wastes with and without the use of catalysts and example of one commercial technology in use today is discussed in detail. The yields of oil and plastic monomers from each technology are compared.
At the end, the future prospects for this technology are presented and India’s progress in developing innovative technologies for plastic recycling is briefly mentioned.

INTRODUCTION:

The need for the biodegradable plastics and recovery of plastic waste has assumed increasing importance in the last few years. Various treatment technologies can use waste plastics as the valuable resources. Mechanical recycling or production using the same material can be recommended as a desired method. But chemical recycling technologies are the objects of interest today, as alternatives for the mechanical recycling techniques.


PLASTIC AND ENVIORNMENT:

Plastics are fundamental in promotion of efficient use of natural resources including energy. Advancement in our understanding on biodegradation has shown that the plastic is environmental friendly compared to many conventional materials with biodegradable label. Some of the eco-friendly aspects of the plastics are listed in table-1
