The objectives of this paper are on the one hand to study and
compare several dechlorination methods in the pyrolysis of PVC
containing plastic wastes, and on the other hand to analyse the
influence of these methods not only on the chlorine content of the
pyrolysis products but also on the characteristics of such products.
There are many references in the literature about the thermal
decomposition of PVC since it is a polymer which produces hydrogen
chloride (HCl) when it is moderately heated, creating toxic and
corrosive conditions. Consequently its sustainability has been under
discussion for many years [4] and for this reason the thermal
behaviour and pyrolysis kinetics of both virgin and waste PVC, either
alone or mixed with other plastics, have been widely studied and
discussed by many authors
