Fionn Ferreira’s magnetic marvel has emerged as a groundbreaking solution in the world of microplastic removal from water, setting a new standard in environmental innovation. He has developed a revolutionary method to extract microplastics from water, a feat that has earned him international acclaim and numerous prestigious awards.
Fionn Ferreira: An Innovator with a Mission
Ferreira‘s journey began in Ballydehob, County Cork, Ireland, where he grew up witnessing the devastating impact of plastic pollution on his beloved coastal areas. This experience ignited a passion in him to combat the microplastic menace, leading to the development of a unique method to quantify and collect these harmful particles.
The Invention: Harnessing Magnetism to Combat Microplastics
Ferreira’s solution involves the use of a unique magnetic mixture known as Ferrofluid is a special type of liquid that becomes strongly magnetized in the presence of a magnetic field. Imagine a liquid that acts like tiny iron filings, sticking to magnets, but still able to flow like water. That's essentially what Ferrofluid is. It's made by suspending tiny particles of magnetite (a type of iron) in a fluid, often oil. This unique property makes it useful in a variety of applications, including Fionn Ferreira's method for removing microplastics from water. https://en.wikipedia.org/wiki/Ferrofluid . This innovative concoction binds to microplastic particles, separating them from water and allowing for their removal using magnets.
The latest prototype of this method removes more than 85% of microplastics in a single pass, without requiring filters or chemicals, and produces zero waste. It can be used safely in drinking water and retains nearly all the magnetic liquid while removing microplastics.
Recognition and Awards: A Global Impact
Ferreira’s invention has garnered global attention. In 2019, he was named the Global Grand Prize Winner at the Google Science Fair. More recently, he won third place in the Young Inventors Prize at the European Inventor Award 2023. His work has also caught the attention of actor Robert Downey Jr’s FootPrint Coalition, a group of activists helping the planet via technology. In 2020, Ferreira founded Fionn & Co to prepare his invention for patenting.

The Future: Scaling Up and Inspiring Others
Ferreira is currently collaborating with a team of engineers in the United States to scale his invention to a commercial model. His startup aims to make microplastic removal a standard in water treatment on a global scale. Beyond his work on microplastic removal, Ferreira is also a sought-after keynote speaker and contributes to events that advance the transition towards a circular economy. He believes in inspiring others to invent and is working on several TV shows and his first book to inspire more people to take action.
Call to Action: Join the Fight Against Microplastics
Ferreira’s story shows the power of innovation in tackling global environmental challenges. But the fight against microplastics is far from over. We can (and must) all contribute to this cause by reducing our plastic consumption, recycling responsibly, and supporting initiatives that aim to clean up our oceans.
