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

To ask the Secretary of State for Environment, Food and Rural Affairs, what steps her Department plans to take to limit microplastic pollution caused by textiles.

The Plan for Water outlined our position that we will expect industry to develop low cost, effective microfibre filters on washing machine and encourage their effective use. With the plan being published only just last month, we are now considering the best actions for its implementation. As a first step, we will look to manufacturers to reduce costs and to provide appropriate evidence of the value of microfibre filters to persuade consumers to invest in them and use them correctly.

Defra funds Textiles 2030, a voluntary initiative with over 110 signatories from the fashion manufacturing industry covering 62% by sales of the UK clothing market. Signatories are committed to circular economy principles such as agreeing good design principles so that their products are durable and recyclable.

Our landmark Environment Act 2021 also provides general powers on design standards and requiring information on the resource efficiency of products. We are, therefore, exploring the best mix of policy measures to tackle the environmental impact of textiles.

Defra supports a range of research including the UK Water Industry Research project (performed by UK Centre for Ecology & Hydrology) which reported in April 2022 that wastewater treatment plants remove 99% of microplastics by number and 99.5% by mass. The Water Industry National Environment Programme (WINEP) includes over £7.39 million of commitment from the water industry to further research microplastics removal through wastewater treatment processes to sludge, which may be a source of microplastics to final effluent discharges.

Technical experts from the Centre for Environment, Fisheries and Aquaculture Science (Cefas) have been leading the Convention for the Protection of the Marine Environment to develop a new indicator for microlitter (including microplastics) in seafloor sediments. This will help us to track progress in reducing plastics in the environment at a regional scale.
