Develop technology to decompose plastics into micro pillow by applying microwave

It seems that Global Resource Corporation, an American company, has developed a technology to return plastics to oil. What you need is microwave, it seems to be decomposed into petroleum, flammable gas, and remaining garbage just by placing it.

Details are as follows.

The machine, "Hawk - 10" developed by GRC, can produce 1,200 different frequencies, which act on specific hydrocarbons to decompose plastic and rubber materials into diesel oil and combustible gas I heard that you can do it. Even with vinyl coated copper wire, it is convenient to not only recycle oil and gas as fuel but also to take out copper wire and recycle, because only outer vinyl can be disassembled into a simple copper wire.

In Japan, researchers at Soseong University in 2006 developed a method to disassemble PET bottles in a microwave oven.

Does it take totally horrible punishment that enormous energy is necessary for this plastic decomposition? If there is no cost problem to handle with this machine, it is a wonderful technology.
