The method developed by the researchers involves placing VVF power cables in a glass reactor where they are subjected to microwave radiation. The pyrolysis carbonizes the PVC insulation, exposing the copper wire and allowing it to be easily recovered.

So putting cables in a microwave to melt the plastic?

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.

This may be an improvement...
