Compostable food containers could release PFAS into environment

Compostable food containers seem like a great idea: They degrade into nutrient-rich organic matter, reducing waste and the need for chemical fertilizers. But much of this packaging relies on per- and polyfluoroalkyl substances (PFAS) to repel water and oil. Now, researchers reporting in ACS’ Environmental Science & Technology Letters have shown that PFAS can leach from the containers into compost. However, the potential health effects of applying this material to crops are unknown.
