Huge number of microfibres are being released into the air by tumble dryers.
Researchers have found that tiny particles of both polyester – a plastic-based material – and cotton are emitted by domestic tumble dryers, with more than half a million finding their way into the air during just 15 minutes of use.

The findings are published in the paper Microfibers Released into the Air from a Household Tumble Dryer.

“A single tumble dryer could be responsible for releasing 120m micro plastic fibres into the air each year,” claims The Guardian in its summary of the research: Hong Kong scientists design simple filter system to capture the harmful microplastics – but there’s a catch.
