Ocean Recherche is promoting marine biomass as its
main raw material for fashion and design applica
tions. The Paris-based company supplies a range of ma
terials developed from ocean resources, aiming to offer
scalable and design-ready alternatives for the industry.
Founder Eugène Riconneaus explained that the idea
grew from a gap in the market. “I couldn’t find next
generation materials that met designers’ expectations
and could scale, so I studied the science to build them,”
he said. This approach led to the creation of marine
biomass-based textile and material solutions designed for
fashion, interiors and industrial design.
Among the company’s first developments are “SeiShell,”
a leather alternative made from marine biomass, and
“SeiYarn,” a fiber derived from ocean-based sources.
These products mark the initial outcomes of the
company’s research and development efforts focused
on sea-sourced innovation.
Positioning itself within the broader shift toward
regenerative and bio-based materials, Ocean
Recherche presents its work through exhibitions and
collaborative design projects. Rather than operating as a
traditional textile mill, the company describes itself as
working at the intersection of marine science, innovation
and material development.
