12 Apr 2023 --- Researchers in the US from the Ames National Laboratory have discovered a way to turn single-use plastic packaging and other petroleum-based products into more environmentally friendly solutions. The study authors claim that using an aluminum reactant and zirconium-oxide-based catalyst can change the chemical structure of polyolefin plastics (PO). The plastics are primarily hydrocarbons comprising long and unbreakable chains of carbon atoms.
