Systematic Study to Convert Polyvinyl Chloride Waste into Commercial Chemicals

Abstract—Polyvinyl chloride (PVC) waste is considered one
of the environmentally hazardous plastic materials
accumulating in huge quantities in landfills. This work was
conducted for the purpose of using green chemistry techniques
to convert the PVC waste into other chemicals that could be
used for commercial purposes. Pyrolysis process of the PVC
waste was carried out under inert atmospheric condition. The
effect of grain size, temperature and heating time on the amount
of evolved hydrogen chloride gas (HCl) was investigated. More
than 95% of theoretical calculated amount of HCl was evolved
before any emission of any other organic fumes. The evolved
HCl was trapped and converted into concentrated hydrochloric
acid (11.22 M) and then to a highly pure sodium chloride salt.
The residual black material was heated further to remove and
trap oily organic fumes. About 14% of initial PVC weight was
found to be as heavy metals free oil and may be used as fuel.
Finally, 27.74% of the degraded PVC remained as carbon
black. The carbon black was grounded and acid digested to
remove and determine heavy metal ions content.
Index Terms—PVC waste, pyrolysis process, thermal degradation, organic fumes, black carbon.
