From recycled shells to upcycled plastics, the pavilion showcases Ostrea Design, Le Pavé, and Anga—three brands pushing the boundaries of sustainable architecture and interior design.
September 5, 2025—The Salon de l’Immobilier Bas Carbone (SIBCA), held at the iconic Grand Palais in Paris, has emerged as France’s premier gathering for low-carbon real-estate professionals, drawing around 200 exhibitors and 12,500 visitors this year. Dedicated to presenting “all low-carbon solutions to design, build, renovate and operate tomorrow’s urban projects and buildings,” the fair fosters high-level interactions among decision-makers, innovators, and leading voices in sustainable architecture and construction.
One of the standout installations this year is the Matériauthèque by Moore Design, showcasing curated, eco-conscious materials that resonate with SIBCA’s ethos of design excellence and environmental responsibility. Moore Design, acting as the Official Furniture Partner, brings its expertise in bespoke, RSE-aligned furnishing to this dynamic showcase, reinforcing a message of circularity and mindful aesthetics.
Discarded Shells Become Luxurious Material by Ostrea Design
Ostrea Design, a Breton deep-tech startup founded in 2020 near Rennes, repurposes discarded oyster, mussel, and scallop shells—currently mostly landfilled—into an elegant, low-carbon material that echoes marble in both look and performance. Composed of 65 % shell flakes and a mineral matrix without any petro-based binders, this eco-material boasts exceptional durability, heat and UV resistance (flame rating M1), and recyclability—produced locally and emitting 16 times less CO₂ than ceramic alternatives. Having just secured €1.2 million in funding, with significant investment from Moore Design’s founder, Ostrea is scaling its production to fulfill growing demand for sustainable surfaces across furniture, flooring, and architectural applications.
At SIBCA 2025, Ostrea’s Matériauthèque presents not just a material but a narrative of coastal circularity—visitors can choose from oyster, mussel, or scallop variants, in natural or subtly tinted hues, including soon-to-arrive black and aqua tones. Technical sophistication meets aesthetic elegance: each batch is polished into custom-sized panels, cured naturally over 28 days, then sealed for high-performance use. The result is a refined, eco-driven design staple yet one rooted in storytelling and regional resilience.
NOTE: Ostrea Design featured its products at Maison&Objet in January 2024, where we had the pleasure of discovering their work.
SoftSurface Panels by Le Pavé
Le Pavé transforms the oft-invisible mass of plastic waste into visible, beautiful, and functional building panels. Through a patented industrial process, this French startup initiates a circular loop by converting 100 % plastic waste—post-industrial and post-consumer—into durable SoftSurface™ panels, without adding any resin. Produced in Île-de-France and Burgundy, the panels carry A+ VOC ratings, meet REACH compliance, and have already graced over 2,000 projects, recycling nearly 1,000 tons of plastic.
At SIBCA, Le Pavé’s presence signals local, scalable innovation—each panel can be cut, sanded, thermoformed, and customized into surfaces, furniture, or architectural elements, highlighting an “aesthetic of waste” where the colorful remnants of plastic carry their origin story. Strategic industrial expansion is underway: its new Saône-et-Loire plant, connected with Veolia’s recycling infrastructure, aims to triple output, turning 1,700 tons of recycled plastic into building-grade materials—demonstrating how regional ecosystems can underpin sustainable construction at scale.
Turning Plastic Bags into Eco-Marble with Anga
Anga reimagines marble by crafting it entirely from recycled plastic. The Paris-based brand has engineered an “ecological marble” using melted sorted plastic waste.
It produces high-quality, lightweight panels resistant to impact and easy to maintain—perfect for countertops, backsplashes, and sleek interior finishes.
Beyond technical performance, Anga imbues materials with design flexibility.
It offers a rich palette of colors and finishes that lend a luxurious marble aesthetic without the environmental cost.
Proudly showcased at SIBCA within the Pavillon Future On Stage, Anga embodies innovation and responsible luxury. The brand’s co-founder frames the mission eloquently:
“By using plastic waste as raw material, we created a revolutionary alternative to natural marble,” blending aesthetic finesse with resilient, planet-forward construction.
This blend of refinement and sustainability positions Anga as a compelling choice for architects and designers seeking to redefine material expectations through ecological creativity.
