A low temperature (420°–480°C) of pyrolysis minimises the gaseous fraction, and allows liquid and solid fractions of high economic value to be obtained; these include light oils, aromatics, paraffin waxes and monomers.
Molten salts, with their excellent heat transfer properties, are interesting media for rapid and regular pyrolysis (problem of reaction kinetics); a eutectic has been selected. Chlorine-containing plastics are also dechlorinated almost completely (using basic salts, which are consumed in the process).
The results of laboratory tests on polyethylene, polypropylene, polystyrene and polyvinyl chloride are given.
Considering the conclusions of the experiments and the possible economic applications, further developments relating to an industrial stage are discussed.

Waste plastics are low in scrap value in the automobile industry and are most difficult to dispose of for reutilization.
The waste plastics have been disposed of by incineration and reclamation as measures for preventing industrial pollution, but these measures involved various problems and quite a different idea could be successfully developed to effectively reutilize them.
