The report, published today (22 November) and entitles ‘Reducing Household Contributions to Marine Plastic Pollution’, reveals that between 9,000 and 32,000 tonnes of microplastic pollution enter British waterways each year from just four sources. The two leading sources are tyre abrasion, with between 7,000 and 19,000 tonnes entering surface waters each year, and clothing.
In the UK an estimated two-thirds of clothing is made from synthetic plastic material, according to analysts from Eunomia, who wrote the report for FoE.
Up to 2,900 tonnes of microplastics from the washing of synthetic clothing such as fleeces could be passing through wastewater treatment into our rivers and estuaries, the report states.
The scale of plastic pollution from household plastics is of the same magnitude as that from large plastic waste such as bottles and takeaway containers – about 26,000 tonnes of which enters UK waterways each year.
The environmental campaign group is calling on the government’s resources and waste strategy – expected next month – to include measures for tackling microplastics as part of a comprehensive action plan.
The four key contributors to microplastic pollution in the oceans from UK sources, according to the report, are:
-
Vehicle tyres: 68,000 tonnes of microplastics from tyre tread abrasion are generated in the UK every year, with between 7,000 and 19,000 tonnes entering surface waters;
-
Clothing: the washing of synthetic clothing could result in the generation of 2,300-5,900 tonnes of fibres annually in the UK – up to 2,900 tonnes of this could be passing through wastewater treatment into our rivers and estuaries;
-
Plastic pellets used to manufacture plastic items. Up to 5,900 tonnes are lost to surface waters in the UK every year;
-
Paints on buildings and road markings – weather and flake-off results in between 1,400 and 3,700 tonnes ending up in surface water every year.
FoE plastics campaignersaid Julian Kirby said: “It’s staggering that so little is being done to prevent thousands of tonnes of microplastic pollution from car tyres, clothing and paints pouring into our rivers and seas every year.
