Summary

Story summary

Researchers at Flinders University in Australia report a new chemical reaction that could revolutionize plastic recycling.
The study identifies a sulfur–sulfur bond process that occurs without heat or light, called trisulfide metathesis.
Trisulfides exposed to specific solvents trigger this spontaneous reaction.
Professor Justin Chalker, senior author at Flinders University, notes the rarity of such a useful reaction, and the findings appear in Nature Chemistry with potential pharmaceutical and biotechnological applications.
