Eco-friendly packaging could be poisoning our compost – USAPosted on September 10, 2019 by DrRossH in Plastic Waste News
Per-and polyfluoroalkyl substances, or PFAS, are everywhere. PFAS are useful, but the major problem with many of them is that they never fully breakdown in the environment—and some have been found to pose serious health risks. That’s why staff at Zero Waste Washington, a nonprofit advocating to reduce waste, were concerned about compostable food packaging, because the paper-based boxes, cups, and plates are lined with—you guessed it—a coating that often contains PFAS.
Heather Trim from Zero Waste Washington called me and said we push everything to be composted that can be composted … but I think we’ve made a big mistake, we didn’t know about these perfluorinated compounds,” recalls Linda Lee, an agronomist at Purdue University. Lee proposed a study to investigate whether these chemicals were making their way into the compost.
