ost-consumer Plastic waste creates severe environmental
issues in the eco system during their disposal, due to their
inherent non-biodegradable nature. Currently in India nearly
15,500 TPD of waste plastic are generated and nearly 60%
of them are collected and mechanically recycled while the
remaining 40%, which could not be mechanically recycled,
are uncollected and littered and enters in to MSW as land
filling. In this aspect, Chemical or Feedstock recycling of waste
polymer is particularly beneficial for it is environmentally safe
and generates more useful chemicals. Thus development of
value added recycling technologies is highly desirable as it
would increase the economic incentive to recycle the waste
plastics. This paper discusses the pyrolysis of mixed post-
consumer waste plastics with various catalysts in a two stage
process involving pyrolysis followed by catalytic cracking.
The yields of resultant value added products like Diesel,
Gasoline and Aromatics are evaluated under various process
conditions. The resultant liquid fuels are characterized for
BIS specifications and studied in internal combustion engine
for their suitability as the transportation fuel. The gaseous
products are analyzed for their chemical composition and
energy content. Moreover, the by products like char are
also characterized and their uses are also explored. The
appropriateness of this process is also evaluated using the
frame work of SWOT. Further recommendations and way
forward for scale up studies also indicated
