The Jelly Cleaner was not born from technical knowledge.
It was born from awareness.

I was 12 years old, and every time I swam in the Mediterranean, I no longer saw only crystal clear water, I saw plastic. I had visited an exhibition about climate change in New York with my grandparents that summer. It deeply impacted me. I even went back a couple more times. When I returned to Spain, I understood that complaining was useless if I wasn’t willing to act. I am not an engineer. I simply wanted to create a simple tool that anyone could make using recycled materials to remove microplastics from the surface of the sea.

But over time, I realized that the most important thing was not just collecting plastic. It was showing it. Making the invisible visible. Because when someone sees with their own eyes the enormous amount of waste and plastic collected during a cleanup, something shifts inside them. And that is where everything begins. Awareness is set in motion.

Today, I am working to develop the Jelly Cleaner in a fully sustainable way and to transform it into a citizen science project — empowering communities not only to clean their waters, but also to collect data, contribute to research, and become active guardians of their own ecosystems.
