Scientists have obtained diamonds from plastic bottles.

During the experiment, scientists fired intense laser flashes at a thin sheet of PET plastic used to make beverage bottles. Powerful pulses heated it up to 6,000 degrees Celsius and created a shock wave that, in a few nanoseconds, compressed the substance to a pressure millions of times higher than atmospheric pressure. The scientists found that this produced diamonds several nanometers in size. A similar process occurs on the ice giants of the solar system - Uranus and Neptune. The experiment of scientists made it possible to confirm that diamond rain really falls on them.
