Heat Boosts Microplastic Shedding from Takeaway Coffee Cups

A new study shows heat is the main driver of microplastic release from takeaway cups: all-plastic cups shed more particles than plastic-lined paper cups, and hotter beverages increase particle release. The researchers found a 300 mL daily hot coffee in polyethylene could lead to about 363,000 microplastics ingested annually. While long‑term health effects remain uncertain, the findings suggest using reusable cups or cooler drinks to reduce exposure, and avoiding pouring boiling liquids into plastic-lined containers.

Hot Cups Leach Microplastics: Temperature Key in Takeaway Coffee

A new study shows takeaway cups shed thousands of microplastic particles when hot, with temperature being the main driver. In Brisbane tests, all-plastic cups released more microplastics than paper cups with plastic linings at both cold and hot temperatures, and hotter liquids increased releases by about one third for plastic cups. The researchers estimate that sipping 300 ml daily from polyethylene cups could expose a person to roughly 363,000 microplastics per year. To reduce risk, use reusable cups or request cooler drinks, and avoid pouring boiling liquids into plastic-lined containers. While health impacts remain uncertain, the study highlights how material choice and heat affect microplastic exposure.
