Question to the Department for Environment, Food and Rural Affairs:

To ask His Majesty's Government what assessment they have made of the potential environmental benefits of mandating microfibre filters on new washing machines.

The Government has already taken significant steps to tackle plastic pollution (e.g. microplastics), including restricting the supply of several single-use plastics through introducing a plastic packaging tax from April 2022; restricting the supply of plastic straws, plastic drink stirrers, and plastic-stemmed cotton buds; and preventing billions of plastic microbeads from entering the ocean each year by introducing a ban on microbeads in rinse off personal care products.

The majority of microfibres are removed through water treatment and analysis of the evidence available to date does not show that there is a sufficient benefit to the environment that can justify legislation to mandate the microfibre filters in new washing machines with prices ranging from £30 to £122 per machine, dependent on manufacturer and whether the filters are disposable or reusable. Defra’s Plan for Water therefore includes a commitment for industry to develop low cost, effective microfibre filters on washing machines and encourage their effective use. We have met industry colleagues and posed this challenge and we look forward to any proposals they are able to share when they are able to do so.
