Valorization of urban and marine PET waste by optimized chemical recycling

چکیده
The degradation of two poly(ethylene terephtalate) (PET) samples from urban and marine wastes (PET-u PET-m, respectively) has been studied by comparing their properties with those virgin PET (PET-v) post-condensed for bottle fabrication (PET-ssp). FTIR spectroscopy, DSC analysis, WCA MFI results have confirmed that all residues were degraded. Therefore, the chemical recycling evaluated in order to valorize PET-m PET-u wastes, analyzing effect on process. Glycolysis degraded non-degraded carried out a pressure reactor at 220°C 30 min. For cases almost pure BHET monomer obtained: 96.5 96.7 % respectively, values 2 13 higher than obtained PET-ssp PET-v. Obtained indicate initial increases content glycolyzed sample.

The accelerated growth of the global urban population implies an increasing demand for public services. Yet, urban centres in developing countries are unable to meet such demand – services such as sanitation are poor or inadequate to cope with the increasing rates of urbanisation and the associated higher standards of living. According to the UN 2002 Human Development Report, 2.4 billion people...
