TI  - Chemical recycling of plastic wastes made from polyethylene (LDPE and HDPE) and 
      polypropylene (PP).
PG  - 536-42
AB  - The recycling of either model polymers or waste products based on low-density 
      polyethylene (LDPE), high-density polyethylene (HDPE) or polypropylene (PP) is 
      examined using the dissolution/reprecipitation method, as well as pyrolysis. In 
      the first technique, different solvents/non-solvents were examined at different 
      weight percent amounts and temperatures using as raw material both model polymers 
      and commercial products (packaging film, bags, pipes, food-retail outlets). The 
      recovery of polymer in every case was greater than 90%. FT-IR spectra and tensile 
      mechanical properties of the samples before and after recycling were measured. 
      Furthermore, catalytic pyrolysis was carried out in a laboratory fixed bed 
      reactor with an FCC catalyst using again model polymers and waste products as raw 
      materials. Analysis of the derived gases and oils showed that pyrolysis gave a 
      mainly aliphatic composition consisting of a series of hydrocarbons (alkanes and 
      alkenes), with a great potential to be recycled back into the petrochemical 
      industry as a feedstock for the production of new plastics or refined fuels.
