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.

What happens if you eat a little plastic?

The good news is that eating a piece of plastic won’t mean you will have the same fate as the poor animals that mistake plastic for food.

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. These are too small to be filtered and so they end up collecting on riverbeds or washing out to sea. Around 20% of plastic in the ocean comes from human activities at sea mostly fishing.
