CityU’s research found clothes dryers are an overlooked source of airborne microfibers

Description

It is well known that washing clothes can release a large number of microfibers into wastewater, but it is unclear whether drying of clothes would have any impact on the environment. A pilot study by scientists from City University of Hong Kong (CityU) reports that a single clothes dryer can discharge up to 120 million microfibres annually — 1.4 to 40 times of that from washing machines.
