Summary

Story summary

Researchers at University of Edinburgh developed a method to convert waste PET plastic into L-DOPA using engineered Escherichia coli.
The process breaks down PET into terephthalic acid, which is then converted into L-DOPA.
The study was published in Nature Sustainability, highlighting bio-upcycling as a way to turn waste into valuable products.
The researchers aim to scale up the method for industrial use and broaden applications of plastic waste in pharmaceuticals.
