POLYMER RECYCLING

Upcycling polystyrene with oxygen and light

Scalable and efficient chemical recycling of commodity polymeric materials remains a challenge as the materials continually accumulate in the environment. Now, upcycling of polystyrene into benzoic acid and other value-added chemicals is realized under mild photooxidation conditions, with hydrogen atom transfer as the key step.
