\n Our Origins\n <\/h2>\n \n \n While certain resources are becoming scarce, the sea continues to generate resources we overlook. \n <\/p>\n

\n That\u2019s what Tanguy, Th\u00e9o, Maxime, and Camille discovered in 2020 in Riec-sur-B\u00e9lon, in southern Finist\u00e8re, while working alongside Breton oyster farmers. Oyster and scallop shells, although abundant, are not recycled: without a dedicated recovery channel, they end up buried in landfill. They decided to tackle the issue at its source: transforming these overlooked volumes into a recycled, low-carbon material, entirely produced in France. A way of reversing the usual production logic, revealing rather than extracting. \n <\/p>\n \n <\/div>\n\n

    \n \"\"\n <\/div>\n \n \n \n \n \n At the origin of Ostrea\u2019s founding idea, Tanguy identified the potential of valorizing shell waste during a stay with his brother, an oyster farmer. From procurement to business development in luxury hospitality and tourism, he built a strong culture of hands-on experience and discipline. His mission: to structure Ostrea\u2019s industrial ambition on solid, sustainable financial foundations.\n <\/div>\n\n \n \n LinkedIn\n <\/a>\n <\/div>\n <\/div>\n\n \n
