This VORS 2023 presentation shared results from recent Vermont studies measuring microplastic contamination in composts, digestates, and food wastes. These findings were placed in context with a broader literature review. The presentation also examined measurement methodologies and outlined a roadmap for connecting science and policy to ensure the benefits of food waste diversion are realized while minimizing the risks of microplastic pollution.

Presenters: Kate Porterfield and Sarah Hobson, UVM
