Scientists use microwave radiation to recover copper from old VVF power cables
A Japan-Italy research team say they have developed a simple and convenient method for recovering copper wires from PVC cables that involves the use of microwave radiation and avoids the generation or use of toxic chemicals.

If no harmful byproducts are produced, can we this to evaporate Plastic?
That's the problem. If you're evaporating plastic then you're definitely releasing a multitude of chemicals; some of which would likely be harmful. Since this is to be performed in large quantities that could be a significant amount of pollution.
This was achieved without the generation or use of toxic chemicals. The researchers explain that during the pyrolysis, the PVC insulation underwent rapid dichlorination and carbonization, which prevented the formation of harmful byproducts such as tar, polycyclic aromatic hydrocarbons and dioxins.
