With increasing amounts of consumption of PET bottles in Bangladesh,
huge amount of solid waste has been accumulated and thus polluting environment
as these are non biodegradable. The aim of this research is to obtain
information on post-consumer PET bottles recycling, its technological and
economic aspects. These goals were attained through literature review of some
current available recycling process and carrying out laboratory experiments of
a recycling process (Dissolution of PET flakes by solvent recovery method using
Cyclohexanone as solvent) being developed in Pilot Plant and Process
Development Center of Bangladesh Council of Scientific and Industrial Research.
FTIR was used to determine the functional group of the product, based on the
peak value. The chemical structure of the standard PET and waste PET, before
and after the restoration process was confirmed by recording their IR spectra.
Experimental results have showed 90% PET recovery and 50% solvent recovery. -See more at:
