    Biggest sources:

    • 7.6 Mt from macro plastics breaking down
    • 1.3 Mt from paint
    • 1.0 Mt from tyres

    10-40 Mt released into environment/year, and increasing.

        I think it depends on measure, if im not mistaken, by weight arohnd 50% of microplastics are tire dust.

          Also depends on where you’re measuring. They make up a ton of the plastics in stormwater runoff for example. Sometimes up to 95% from what I found. And that stormwater often ends up in our drinking water.
