ClearRelease of Microplastics from Reusable Kitchen Plasticware and Generation of Thermal Potential Toxic Degradation Products in the Oven
Kitchen plasticware including containers and baking molds was tested for microplastic release during oven use, finding that heating generated both microplastic particles and potentially toxic thermal degradation products at levels dependent on material type and temperature. The results identify reusable kitchen plastics as an underappreciated source of microplastic and chemical exposure during everyday cooking.
Identification and characterization of microplastics released during the actual use of disposable cups using laser direct infrared imaging
Researchers found that disposable polypropylene and polystyrene cups release over 1,000 microplastic particles per liter when filled with hot water, with higher temperatures producing more particles. Using a disposable cup three times a day could mean unintentionally swallowing 294 to 402 microplastic particles daily. The study suggests that reusable cups release fewer microplastics and may be a safer choice for regular hot beverage consumption.
Evidence of Sub‐Micrometric Plastic Release When Heating Food Containers Based on Light Scattering Measurements
Researchers used light scattering measurements to detect sub-micrometric plastic particles released from food containers when heated. They found evidence that food-grade containers release tiny plastic fragments during normal heating conditions, at sizes below what most conventional detection methods can capture. The study suggests that current estimates of microplastic exposure from food packaging may undercount the actual amount released.

Researchers tested how many microplastics are released from common takeaway food containers made of polypropylene, polystyrene, and PET when exposed to different temperatures and acidic conditions. PET and polystyrene containers released microplastics under all conditions, with significantly more released at high temperatures (100 degrees Celsius). Notably, polypropylene containers released no detectable microplastics, suggesting they may be a safer choice for hot food and beverages.

Researchers measured microplastics released from plastic food containers during normal rinsing and when exposed to different food types and temperatures. All containers released microplastics matching their material, and high-fat foods, extreme temperatures, and longer exposure times increased the amount released. This study confirms that plastic food packaging is an important and direct source of microplastic exposure for people through their everyday meals.

Microplastic and PTFE contamination of food from cookware
Researchers tested whether plastic cookware releases microplastics into food during everyday cooking steps like heating, mixing, and storage, and found that both new and old plastic cookware introduced thousands of plastic particles per year into home-cooked meals. Non-plastic cookware did not add any microplastics, suggesting that switching to non-plastic pots and utensils could meaningfully reduce dietary microplastic intake.
