Fionn Miguel Eckardt Ferreira (from Ballydehob, County Cork, Ireland) is an Irish inventor, chemistry student and Forbes 30 under 30 listee.

[1] Ferreira spent part of his childhood kayaking around remote coastal areas of Ireland with his dog India, noticing an increasing amount of plastic washing up on the coastline.

Ferreira has stated that he was inspired by an article by Fermilab physicist Arden Warner, who developed a new approach to cleaning up oil spills, using magnetic principles,[10] and made a device that uses a magnet-based method to remove the particles from water with extraction rates of 87% (+/- 1.1%).

[12] In autumn 2019, Ferreira started a BSc in Chemistry at the University of Groningen in the Netherlands and graduated in 2022 with Cum Laude.

[16] In 2018 the MIT Lincoln Laboratory named a minor planet after Ferreira, following his being awarded 2nd place at the Intel International Science and Engineering Fair.
