Mr Costa introduced a Bill to require manufacturers to fit microplastic-catching filters to new domestic and commercial washing machines, aiming to mitigate the release of microfibres into wastewater systems. He cited research indicating that around half a million tonnes of microfibres from synthetic textiles are released into oceans annually due to washing clothes, highlighting the need for action to protect aquatic environments and human health. Mr Costa emphasised that filters can reduce fibre release by 78% in every wash cycle, with some manufacturers claiming up to 90%. He noted cross-party support for his Bill and referenced international efforts like France's legislative steps towards requiring microfibre filters in all new washing machines.
