Microplastics are plastics less than 5mm in diameter. Under this category, nurdles are pre-production plastic pellets transported via cargo ships which, upon arrival, are melted down to form any plastic product imaginable. Nurdles are spilt at all points in their production including through transportation on cargo ships which is how billions upon billions of nurdles are washed up onto South-West beaches. A percentage of nurdles are also bio-beads used in waste water treatment.
