Did you know you might be eating a credit card’s worth of plastic every week?
Microplastics in kitchen appliances are a growing concern, with millions of tiny plastic particles shedding into our food, water, and air every day. As a primary source of microplastic pollution, kitchen appliances like coffee makers, toasters, and blenders can contaminate our homes and harm our health. But what are the main sources of microplastics in kitchen appliances, and how can we reduce our exposure? In this article, we’ll explore the risks associated with microplastic pollution, identify the kitchen appliances that shed the most microplastics, and provide practical tips for minimizing microplastic exposure in your kitchen.
Microplastic Pollution from kitchen Appliances: A Growing Concern
A typical kitchen is equipped with a variety of appliances, including but not limited to kettles, microwaves, ovens, kitchen fans, vacuum cleaners, brooms, toasters, air fryers, refrigerators, dishwashers, freezers, electric whisks, and mixers. In some cases, kitchens may also feature washing machines and dryers.
Despite the widespread presence of these appliances, our comprehensive search revealed that remarkably few studies have investigated the release of microplastics from kitchen appliances. While a handful of studies have explored microplastic release from kettles, there is a significant dearth of research on other commonly used kitchen appliances.
One study that did examine kettles found that boiling water in plastic kettles resulted in the release of micro- and nano-plastics. Notably, the researchers observed a substantial decrease in the release of micro- and nano-plastics from the plastic kettle after an extended period of usage.

The authors attributed this phenomenon to a natural passivation process, whereby the formation of chemical films within the kettle, influenced by the chemical composition of local water supplies, acts as a barrier to the release of micro- and nano-plastics. This finding suggests that the release of microplastics from kitchen appliances may be influenced by a complex interplay of factors, including
- Appliance design
- Usage patterns
- Environmental conditions.
The Overlooked Source of Microplastics in Kitchen Appliances
In many countries, including the United Kingdom, washing machines and dryers are often installed in kitchens. While these appliances have been extensively studied as sources of microplastics in the environment, their potential contribution to microplastic contamination within domestic kitchens remains largely unexplored.
Microfibers: A Primary Source of Microplastics
Microfibers, which originate from natural and synthetic textiles, are a primary source of microplastics. Research has shown that over 50% of microfibers are released during washing and wearing, posing a significant risk to human exposure. Textiles in Western households, including clothing, dish cloths, hand towels, upholstery, curtains, and carpets, can all contribute to microfiber release.

The Impact of Laundry Facilities on Indoor Microplastic Exposure
Indoor exposure to microplastics is a growing concern, as people spend approximately 90% of their time indoors. Studies have shown that microplastic deposition rates indoors are substantial, with small fibrous particles being the most prevalent. These particles are small enough to be inhaled deep into the lungs, potentially causing physiological harm.
Factors Influencing Microfiber Release from Washers and Dryers
Several factors can influence the release of microfibers from washers and dryers, including appliance efficiency, washing and drying conditions, and fabric quality. However, placing dryers in kitchens and living areas may increase exposure risks through air and deposition on kitchen surfaces.
Reducing Microplastic Exposure in Kitchens
Relocating laundry facilities away from living spaces could be an effective strategy to reduce daily exposure to microplastics in the form of microfibers. By understanding the sources of microplastics in kitchen appliances and taking steps to mitigate them, we can reduce our exposure to these harmful particles and create a healthier indoor environment.
Final Words
Reducing microplastic exposure in kitchens is crucial. While microplastics are inevitable, considering utensil, cookware, and equipment usage can help minimize exposure. Food preparation, storage, and cooking materials significantly contribute to microplastic contamination. Mechanical, physical, and chemical processes generate microplastics from plastic materials during food preparation. Factors like material quality, temperature, and age influence microplastic release. Non-stick cookware, utensils, and cleaning equipment can all shed microplastics, while kitchen appliances like washing machines and dryers can increase airborne microplastic fibers. By acknowledging these sources, we can take steps to mitigate microplastic exposure in our kitchens.
