Food Waste Microplastics with Kate Porterfield and Dr. Eric Roy

Oct 20, 2023

“Microplastics in Composts, Digestates and Food Wastes: A Review” with Kate Porterfield, PhD Candidate at University Vermont and Dr. Eric Roy, Associate Professor at University of Vermont.

Diverting organic materials and food waste from landfills and recycling them for beneficial use in agriculture is a great way to reduce greenhouse gas emissions. However, intermingled microplastics from packaging and other sources could make these recycled materials less beneficial than they otherwise might be. This episode, Kate and Eric discuss their review paper studying the prevalence of these contaminants, how they’re measured, and how these results intertwine with current policy efforts.

Tune in to learn:

·         How microplastics can get into food waste

·         How scientists measure microplastics

·         Needs for syncing research and policy

·         How factors like weight, density, and mass can impact microplastic measurements
