Euronews OCEAN Season 7, Episode 4 - Circular blue economy

From France’s Atlantic coast to the Spanish Mediterranean, marine industries are finding new ways to turn their waste into treasure. Discarded oyster shells and abandoned fishing nets, once considered worthless, are now being repurposed into eco-friendly building materials and street furniture through innovative upcycling projects.

In this episode of Ocean, we meet French researchers at the University of Pau and Pays de l’Adour, who have developed eco-friendly concrete made from crushed seashells instead of traditional sand and gravel, combined with clinker-free cement that emits 75% less CO₂ than conventional construction cements.

We also visit Spain’s Mediterranean coast, where the EU-supported initiative Gravity Wave partners with local fishers to collect and recycle discarded nets that would otherwise end up in landfills or drift at sea.
