flag Scientists turned plastic waste into L-DOPA, a Parkinson’s drug, using engineered bacteria.

flag Scientists at the University of Edinburgh have created L-DOPA, a drug used to treat Parkinson’s disease, by converting plastic waste from used bottles using engineered bacteria. flag The process breaks down PET plastic into terephthalic acid, which is then transformed into L-DOPA through natural biological reactions. flag This marks the first time plastic waste has been turned into a therapeutic for a neurological condition. flag The method offers a more sustainable alternative to fossil fuel-based drug production and could help launch a bio-upcycling industry for medicines, fragrances, and industrial chemicals. flag The research, published in Nature Sustainability, was conducted at the university’s Carbon-Loop Hub and supported by UKRI and IBioIC. flag The team is now working to scale the technology for industrial use.
