Scientists Turn Plastic Into Diamonds In Breakthrough

The production of nanodiamonds from PET plastic paves the way toward a new form of recycling, and even has implications for exoplanets that rain diamonds.

In 2017, researchers in Germany and California found a way to replicate those planetary conditions, fabricating teeny tiny diamonds called nanodiamonds in the lab using polystyrene (aka Styrofoam). Five years later and they’re back at it again, this time using some good ol’ polyethylene terephthalate (PET), according to a study published on Friday in Science Advances. The research has implications not only for our understanding of space, but paves a path toward creating nanodiamonds that are used in a range of contexts out of waste plastic.
