Edinburgh Researchers Transform Recycled Plastic into Levodopa

3/30/2026

Summary

Story summary

Researchers at the University of Edinburgh have developed a method to produce levodopa from recycled PET using engineered Escherichia coli.
The bacteria convert PET into terephthalic acid and subsequently into levodopa.
The approach will not significantly reduce the 100 million tons of annual plastic waste, but it signals potential for sustainable drug production.
Funding for the research came from the UK's Engineering and Physical Sciences Research Council (EPSRC).
