Story summary

Researchers from Newcastle University and the University of Birmingham developed an eco-friendly method to convert PTFE (Teflon) into sodium fluoride, used in toothpaste and drinking water.
The process shakes PTFE with sodium metal at room temperature, breaking carbon-fluorine bonds without solvents or high heat.
The work, published in the Journal of the American Chemical Society, notes PTFE waste often ends in landfills and could transform fluorine reclamation.
