Iván Hernández Dalas: I developed an app that uses drone footage to track plastic litter on beaches
By Gerard Dooly , University of Limerick Plastic pollution is one of those problems everyone can see, yet few know how to tackle it effectively. I grew up walking the beaches around Tramore in County Waterford, Ireland, where plastic debris has always been part of the coastline, including bottles, fragments of fishing gear and food packaging.

Community groups do tremendous work cleaning these beaches, but they’re essentially walking blind, guessing where plastic accumulates , missing hot spots, repeating the same stretches while problem areas may go untouched. Years later, working in marine robotics at the University of Limerick, I began developing tools to support marine clean-up and help communities find plastic pollution along our coastline. The question seemed straightforward: could we ...
