Plastic pellets, powders, and flakes - A key source of microplastics to the environment: Fate, effects, and mitigation strategies

Summary

This report reviews existing research on tiny plastic pellets, powders, and flakes—raw materials used to make plastic products—which spill or leak into the environment at nearly every stage of manufacturing and shipping, breaking down further into microplastics. These particles can end up in soil, water, and eventually the food chain, adding to growing concerns about human exposure to microplastics, though more research is needed to fully understand the health effects. The takeaway: better handling and containment during plastic production could meaningfully cut down on one major, often-overlooked source of microplastic pollution.
