How it works

The microwave assisted pyrolysis process is carried out inside a reactor consisting of two chambers: tyres to be treated are placed in the loading and safety chamber, followed by the pyrolysis chamber in which the process takes place. Hydrocarbon vapours that develop during the process are condensed and collected by a condensing system, while uncondensable gases can be fired or used for cogeneration. After the process, the solid materials, carbon black and steel, are transferred from the pyrolysis chamber to the cooling chamber and through a post-treatment it is possible to obtain the separation of the different materials.


The application of microwaves to pyrolysis allows to overcome the critical issues typical of classic pyrolytic processes such as transients of switching on and off that cause unsustainable stoppage of machine. Acting directly on the material to be treated, microwaves allow a uniform heat transfer which ensures a homogeneous distribution of temperatures inside the reactor. This results in a different heating rate and a different vapours residence time in the reactor compared to classical pyrolysis, allowing a better profile of the chemical composition of the pyrolysis products.

This technology consequently ensures an easier management both in terms of process and machine structure.
