Innovative material made from recycled shells. French, high-performance, and low-carbon, it is designed for flooring, countertops, and furniture.
Each year in France,
250,000 tonnes of shell waste from shellfish farming end up in landfill sites. We give them a new life by incorporating them into our material.
The material
Eco-friendly
OSTREA material is composed of 55% shell flakes and 45% mineral matrix (resin-free).
Recycled & Renewable
Recyclable
Low carbon
Made in France
High performance
The material has technical properties similar to those of natural stone. Its density ranges between 2200 and 2400 kg/m³ (44–48 kg/m²). OSTREA technology is a patented innovation
UV-resistant
Impact-resistant
Stain-resistant
Custom-made
We create your custom projects using slabs measuring 305 × 145 cm (2 cm thick).
For floor tiles and furniture tops, we handle custom manufacturing directly.
For your kitchen, bathroom, or B2B fit-out projects, production is entrusted to one of our partner stonemasons, as these applications require professional installation and craftsmanship.
