Steam-cracking of waste plastics to produce monomers

Thermal decomposition of different types of waste polyethylene (PE) and polypropylene (PP) is presented.

Cracking of waste plastics is executed in multi-section laboratory-size tubular reactors in presence of steam. Granulated polymer particles are melted and fed into the reactor by a special-design lab extruder.
