Tumbling Dicey?

Microplastic fibres damage both human health and the environment. Although material shed from tyres and brake-linings of vehicles, must give them a 'run for their money', a Hong Kong scientist claims that tumble driers are currently the major source of microplastic fibres (https://www.theguardian.com/environment/2022/jan/12/tumble-dryers-leading-source-microfibre-air-pollution-hong-kong-plastics). The scientist estimates that a single tumble drier, filled with polyester clothing, can jettison into the air 120m microplastic fibres each year. Filters can be designed to capture these fibres. It would, perhaps, be better to change the nature of clothing fabrics. Cotton fibres are less damaging to the environment than counterparts from polyester.
