AI Summary

Researchers from the University of Queensland’s Queensland Alliance for Environmental Health Sciences tested single‑use coffee cups lined with either fossil‑based polyethylene or the biodegradable polymer polylactic acid. Both cup types released plastic particles into the coffee, but the PLA‑lined cups emitted roughly twelve times more particles than the polyethylene‑lined cups. The findings highlight that even biodegradable‑labelled cups can contribute significantly to microplastic contamination in beverages.
