I beg to move,

That leave be given to bring in a Bill to require manufacturers to fit microplastic-catching filters to new domestic and commercial washing machines; to make provision about the promotion of the use of microplastic-catching filters in washing machines and raising awareness about the consequences of microplastics from washing machines for pollution in rivers and seas; and for connected purposes.

Two years ago, I presented this ten-minute rule Bill to the House, and I am grateful to the many colleagues who have since approached me to express support and encourage me to present it to the House again. I thank colleagues who have co-sponsored my Bill this time round, and I am pleased to inform you, Madam Deputy Speaker, that it has cross-party support, with co-sponsors from the Labour party, the Liberal Democrats, the Green party, the DUP and the Conservatives.

Microfibre plastic pollution is one of the most pervasive and preventable forms of microplastic pollution; in fact, around half a million tonnes of microfibres from synthetic textiles are released into the oceans each year due to washing clothes. I am introducing this Bill to encourage the Government to collaborate with washing machine manufacturers and set standards to ensure that all new domestic and commercial washing machines are fitted with cost-effective microfibre-catching filters.

Microfibres, which are shed during the wash cycle, are too small to be captured by existing washing machine filters. They make their way into wastewater systems, where they either end up as sewage sludge, which is later spread on our agricultural land, or escape treatment entirely, ending up in rivers and seas. Research now indicates that these fibres, once released, not only contaminate aquatic environments but travel up the food chain, making their way into an alarming amount of the fish that we all eat.

The growing body of scientific literature on microplastics is truly alarming. We are not only eating and drinking these particles, but the latest research from the University of New Mexico shows that they have now, sadly, crossed into our blood, into human placentas, into breast milk and even into our brains. Our bodies are now contaminated by microplastics. We should all be concerned that in lab studies conducted by Hull York Medical School, microplastics have been shown to damage human cells, and while the full impact on our health is still unknown, the evidence is mounting that numerous adverse health effects—including endocrine disruption, respiratory disorders, autoimmune issues and certain cancers, to name but a few—are caused or exacerbated by microplastics in our bodies. Researchers have even found microplastics in human testicles, and this may be a major factor in the dramatic drop in sperm count over the last 40 years.

I hope the Government are convinced that microplastics pollution is a now major problem to our environment and our health, but how effective can microplastics filters in washing machines be in addressing microplastics pollution at source? There are two factors that should persuade the Government. First, they may be surprised to learn that a 2017 study revealed that 35% of all microplastics released into the environment are shed from our own clothing. That means that over a third of environmental microplastics are coming from a single source, which we know how to reduce. Secondly, evidence shows that washing machine filters can reduce the release of microfibres by 78% in every wash cycle, with some manufacturers now claiming that their new products are able to take up 90% of these offending plastic pollutants.

Countries such as France have already taken legislative steps to require microfibre filters in all new washing machines from next year, and Australia has an industry-led goal of introducing these filters in six years’ time, so the UK can and should do its part. The United States Senate introduced the Fighting Fibers Act earlier this year. This is a promising federal initiative, which, although still in its early stages, is a mandate for filters in washing machines. The world is starting to wake up to this problem, and the UK has an opportunity to show leadership by introducing legislation that could make a substantial difference. This is not just about setting an example; it is about honouring our commitment to the environment and the health of the British people.

As chair of the all-party parliamentary group on microplastics, I have worked alongside numerous stakeholders including the obvious ones such as environmental groups, but also with industry leaders, washing machine manufacturers, academics and, in particular, the Women’s Institute, which first brought this to my attention seven years ago when it was here lobbying MPs. They have all helped to identify viable solutions. Together, we believe that fitting microfibre filters on washing machines is a cost-effective, achievable, near-term solution that would have a significant impact on reducing plastic pollution and its effect on our health.

British companies are already leading in the design and manufacturing of these filters, showcasing the innovation and capability needed to support this measure. I urge the Government to work with these businesses to position the UK as a global leader in the fight against plastic pollution. My Microplastic Filters (Washing Machines) Bill is a low-cost, practical approach to a serious problem, and it aligns with the UK’s ambition to build a sustainable and environmentally conscious society. Microfibre pollution is an urgent environmental issue, and this Bill represents a clear, immediate and simple step we can take to address it, with the backing of washing machine manufacturers. I urge my colleagues in Government to support the Bill and to work with white goods manufacturers to enact a solution that has virtually no cost to the consumer and that provides the safeguards that we need for our environment and our health.

Question put and agreed to.

Ordered,

That Alberto Costa, supported by Sarah Champion, Jim Shannon, Sir Julian Lewis, Ellie Chowns, Ruth Jones, Peter Dowd, Siân Berry, Carla Denyer and Mr Alistair Carmichael, present the Bill.

Alberto Costa accordingly presented the Bill.

Bill read the First time; to be read a Second time on Friday 7 March 2025, and to be printed (Bill 114).
