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

To ask the Secretary of State for Environment, Food and Rural Affairs, what steps his Department is taking to (a) prevent microplastics from entering the natural environment and (b) tackle the damage caused by microplastics that are in the natural environment.

Defra funded a 5-year-long study to investigate the potential harm caused by microplastics in the marine environment. On the basis of the results of this study, last year we introduced one of the world’s strongest bans on microbeads in rinse-off personal care products. Microbeads, like other microplastics, do not biodegrade and therefore accumulate in the environment.

To address the evidence gaps surrounding other sources of microplastics, we are funding research by the University of Plymouth into textiles and tyres which are estimated to be significant sources of microplastics in the marine environment.

Water infrastructure is an important pathway for contaminants, including microplastics, to enter the aquatic environment. We are working with water companies and researchers to understand the scale of the issue, evaluate the effectiveness of treatment systems at removing microplastics and assess the impacts of microplastics in aquatic environments.

Our priority will continue to be preventing plastic entering the environment in the first place and eliminating avoidable plastic waste over the lifetime of the 25 Year Environment Plan. The Resources and Waste Strategy, published in December last year, sets out our plans to eliminate avoidable plastic waste. We will take action at each stage of the product lifecycle: production, consumption and end of life.
