Shells Become Structures
In the French bay of Arcachon, oyster farmers and scientists are transforming discarded shells into low-carbon concrete – strong, fibrous, and visually impressive.
Eco-Concrete in Action
At the Dune du Pilat, tourists now walk on a 100-meter-long path made of shell-based concrete, which is being tested for its durability under heavy foot traffic.
Historic Ports, Modern Materials
In Socoa, a shell-derived mortar is being tested on centuries-old harbor walls, designed to cure underwater and withstand harsh marine conditions.
Promoting Biodiversity
Shell concrete blocks placed near the coast are showing early signs of supporting marine life – with potential for reef restoration and habitat creation.
A New Coastal Economy
Across Southern Europe, ocean waste is being rethought – as a resource that combines sustainability, resilience, and innovation.
