Microwave Pyrolysis of Plastics

Plastics cannot absorb microwave energy, as it has a very low dielectric loss factor. Therefore,
an absorbent must be mixed with the plastic to aid in heating the plastic in pyrolysis. Materials with high
dielectric loss factor are good candidates as an absorbents for plastic pyrolysis e.g. tyre shredded, silicon
carbide and carbon. The mechanism of plastic microwave pyrolysis is based on absorbing the microwave
energy via absorbent and subsequently transferring thermal heat to the plastic via conduction. The physical
properties and the volume ratio of the absorbent affects the uniformity of heating distribution.
