Filters can cut the volume of ocean-bound microplastic fibres released by washing machines, a study has shown.
However, until now, filters have not been tested under scientific conditions to prove their effectiveness.
In the first study of its kind, scientists found that the majority of fibres were removed but up to a third were still getting though.
Each year, an estimated 50 billion garments are washed in machines around the globe.
Mark Browne from the University of New South Wales, and colleagues Macarena Ros and Emma Johnston, observed: “Facilities that treat sewage divert some fibres to sludge, but no current method of filtration eliminates their environmental release.”
One possible solution was to stop the
