Modified bacteria convert plastic waste into pain reliever

Dealing with plastic waste is a real headache. But with a little help, bacteria can turn plastic into a painkiller.

Genetically engineered Escherichia coli bacteria converted a broken-down plastic bottle into the active ingredient in pain medicines like Tylenol and Panadol, scientists report June 23 in Nature Chemistry.

The approach could help reduce plastic pollution and curb reliance on the fossil fuels now used to make the ubiquitous medication. “I genuinely think this is quite an exciting sort of starting point for plastic waste upcycling,” says Stephen Wallace, an engineering biologist at the University of Edinburgh.
