In the coming years, we will likely see further developments of Ferreira’s technology alongside other approaches, as teams around the world work together to solve the increasingly urgent plastic pollution issue.

What problems do microplastics cause?

If ingested, microplastics can block the gastrointestinal tracts of organisms, or trick them into thinking they don’t need to eat, leading to starvation. Many toxic chemicals can also adhere to the surface of plastic and, if ingested, contaminated microplastics could expose organisms to high concentrations of toxins.

Why are there so many microplastic particles in the ocean?

An average load of laundry might release around 700,000 microplastic fibres, less then a millimetre in length, into the water.
