Microplastics Release and Its Effect during Tumble Drying
Summary
This review paper pulls together existing research showing that tumble drying your clothes, not just washing them, releases tiny plastic fibers (microplastics) into the air, which you can then breathe in. Since inhaling these particles may pose health risks that scientists are still studying, the authors suggest simple fixes like air-drying clothes and regularly cleaning your dryer's lint trap, while also calling for better product design and stronger regulations to cut down on this overlooked pollution source.
Microplastics (MPs) are increasingly recognized as pervasive environmental pollutants, with textiles identified as a dominant source. While significant attention has been devoted to fiber release during washing, the contribution of tumble drying to MP emissions has often been overlooked. This chapter consolidates current scientific understanding on the mechanisms, quantities, and pathways of MP release during tumble drying. Case studies highlight the scale of fiber shedding and its contribution to airborne, waterborne, and solid-waste pathways. The implications for human health, particularly through inhalation, are reviewed alongside ecological impacts. Strategies for mitigation are discussed at consumer, appliance, textile, and policy levels. Emerging international standards and regulatory frameworks, particularly within the European Union, offers pathways to align research, product design, and policy. By emphasizing both traditional practices, such as line-drying and lint maintenance, and technological solutions, the chapter argues for a combined approach to reducing MP emissions from drying. It concludes with opportunities, challenges, and future outlook, underscoring the need for harmonized test methods and stronger policy instruments.
