Recycling household PET waste—such as plastic bottles—using a new chemical process could generate a compound useful for synthesizing drugs, according to a study published in the journal Angewandte Chemie International Edition. The team discovered that, thanks to semi-hydrogenation, the waste could be broken down into a compound called EHMB, which is key to producing the cancer drug imatinib, a chemotherapy drug called procarbazine, and the insecticide fenpyroximate.

The Royal Swedish Academy of Sciences has awarded the Nobel Prize in Chemistry 2023 to Moungi G. Bawendi, Louis E. Brus, and Alexei I. Ekimov "for the discovery and synthesis of quantum dots." Quantum dots are tiny nanoparticles that diffuse their light from televisions and LED lights, and can also guide surgeons when removing tumor tissue, among many other applications.
