There is a quiet revolution happening in the world of architecture and interior design — and it starts with eggshells, nut husks, and rice. Ottans, the sustainable bio-composite material pioneered by Ottan Studio, is challenging the way we think about surfaces, spaces, and the things we build with. In an industry long dominated by synthetic laminates, petroleum-based boards, and carbon-heavy materials, Ottans offers something genuinely different: high-performance panels engineered entirely from food and agricultural waste. This is not a niche concept for eco-exhibitions. It is a commercially viable, aesthetically striking material movement that is reshaping the design landscape from London to Istanbul.
What Are Ottans, Exactly?
At their core, Ottans are bio-composite panels made by transforming discarded organic materials into durable, design-ready surfaces. The term is deeply tied to Ottan Studio, a green-tech design company that operates between London and Turkey. Over time, the name Ottans has evolved beyond a product label — it now represents an entire sustainable design philosophy grounded in circular economy principles and regenerative material innovation.
The materials used in Ottans panels include eggshells, nut shells, lentils, rice husks, grass clippings, fruit peels, and other organic byproducts sourced from farms and food processors. These ingredients are collected, cleaned, dried, and ground into fine particles before being combined with eco-friendly bio-resins. The resulting mixture is then molded under controlled pressure and temperature into finished panels that can be cut, drilled, sanded, laser-engraved, and CNC machined — making them highly adaptable for both industrial and artisanal design workflows.
The Circular Economy Logic Behind the Material
The logic behind Ottans is rooted in what economists and environmentalists call the circular economy — a production model that eliminates the concept of waste by designing materials and products to re-enter the supply chain rather than end up in a landfill. Traditional manufacturing follows a linear path: extract, produce, use, discard. Ottans inverts that model entirely. What would otherwise be agricultural waste becomes the raw input. The so-called “end” of one product’s lifecycle becomes the beginning of another’s.
According to the Ellen MacArthur Foundation, transitioning to a circular economy could generate $4.5 trillion in economic value by 2030 while dramatically reducing global carbon emissions. Ottans sits directly within that opportunity — a material solution that makes circular thinking tangible and beautiful.

A Closer Look at the Ottans Material Collections
One of the most compelling aspects of Ottans is the depth and variety of its material collections. Each line serves a distinct design and functional purpose, making the range suitable for everything from minimalist residential interiors to acoustically engineered commercial environments.
Core Line: Grounded in Familiar Waste Streams
The Core Line includes flagship materials like Eggy, Nutty, Nuts, and Moon. Each variant uses a different waste stream, producing unique surface textures and natural color stories. Eggy, as the name suggests, incorporates crushed eggshells, resulting in a speckled, almost terrazzo-like finish. Nutty and Nuts use ground nut shells that give the panels a warm, earthy character with rich tactile depth. Moon takes a more restrained approach, offering a refined, minimalist surface with subtle organic detail — ideal for contemporary or Japandi-inspired spaces.
Seasonal, Translucent, and Acoustic Variants
Beyond the Core Line, Ottans offers a Seasonal Line crafted from grass, dried leaves, lentils, and even expired food products. Because the raw materials change with the harvest calendar, no two seasonal batches are identical — a characteristic that adds genuine authenticity and collectibility to each panel. The Translucent Line, made with rice and fruit waste, allows light to pass through the surface, making it ideal for backlit partitions, sculptural installations, and creative lighting features. The Acoustic Line is engineered for sound absorption and suits environments like offices, hotels, and hospitality venues where ambient noise management matters.
The Stone Line: A Rethinking of Natural Stone
The Stone Line deserves particular attention because it directly challenges one of the most resource-intensive materials in construction: natural stone. Quarrying stone requires significant energy, destroys habitats, and generates considerable CO2 through transport and processing. The Ottans Stone Line replicates the weight, solidity, and visual gravitas of stone while incorporating high volumes of upcycled content. This makes it a compelling sustainable alternative for countertops, flooring, and feature walls where the look of stone is desired without the environmental cost.
Where Ottans Is Being Used — and Why It Works
The application range for Ottans materials is broader than most people initially expect. Far from being limited to decorative accent walls or exhibition installations, Ottans has found its way into mainstream commercial and residential projects. Interior architects are using the panels for wall cladding, ceiling treatments, and feature shelving. Furniture designers are incorporating the material into tables, stools, and storage units that marry slow design principles with organic aesthetics.
In retail and hospitality environments, where brand storytelling is crucial, Ottans communicates sustainability in a tactile and immediate way. Customers and guests can see and touch surfaces made from materials they would otherwise throw away — a powerful statement about a brand’s values. Hotels that have incorporated Ottans into their interiors report that guests frequently ask about the material, turning each surface into a conversation about environmental responsibility.
Beyond architecture and furniture, Ottans is also finding its way into product design. Lighting fixtures, home accessories, jewelry, and even automotive interior components have been prototyped using Ottans bio-composites, demonstrating just how adaptable the material is across scales and industries.

Ottans vs. Traditional Materials: An Honest Comparison
Understanding why Ottans matters requires an honest look at what it replaces. MDF (medium-density fibreboard) is one of the most widely used materials in furniture and interior construction, yet it relies on formaldehyde-based resins that release volatile organic compounds (VOCs) into indoor air over time. Plastic laminates are petroleum-derived and virtually non-recyclable. Synthetic composites often combine multiple materials in ways that make disassembly and end-of-life processing extremely difficult.
Ottans, by contrast, reduces reliance on fossil fuels, avoids harmful adhesives where possible, and diverts organic material from landfill. While Ottans panels are not yet positioned as outdoor-weatherproof solutions in all conditions, their mechanical strength, moisture resistance (depending on finish), and acoustic performance make them highly competitive for the indoor applications that represent the vast majority of design projects. The material also brings something conventional panels fundamentally cannot: authenticity. Every Ottans surface is unique because its ingredients are organic and variable.
The Bigger Picture: Ottans and Global Sustainability Goals
The emergence of Ottans aligns with a growing global consensus that the building and design industries must fundamentally change. The construction sector accounts for approximately 38% of global energy-related CO2 emissions, according to the United Nations Environment Programme. Material choices — what goes into a wall, a countertop, a ceiling — are not trivial decisions. They carry environmental weight that compounds across millions of projects worldwide.
Ottans aligns with the United Nations Sustainable Development Goals, particularly SDG 12 (Responsible Consumption and Production), which calls for sustainable management and efficient use of natural resources. For architects and designers working toward green building certifications like LEED or BREEAM, specifying Ottans materials can contribute to responsible sourcing credits and support broader project sustainability scores.
Scaling Challenges and the Road Ahead
Like any emerging material innovation, Ottans faces real challenges on the path to mainstream adoption. Scaling production to meet global demand while maintaining quality and consistent waste sourcing is a significant operational hurdle. Cost competitiveness with mass-produced synthetics remains an ongoing challenge, though the gap is narrowing as awareness grows and production volumes increase. Ongoing material research is expected to improve durability, water resistance, and expand outdoor applications in the coming years — potentially opening up entirely new markets in infrastructure and transportation.
Why Forward-Thinking Designers Are Choosing Ottans
The designers and architects who specify Ottans are not simply making an environmental statement — they are choosing a material that genuinely elevates their work. The irregular textures, natural color variations, and visible fragments of organic material create surfaces with a depth and honesty that synthetic materials cannot replicate. In a design culture increasingly fatigued by perfection and uniformity, there is a growing appetite for materials that carry a story, a provenance, a sense of place, and process.
Biophilic design — the practice of connecting interior spaces to the natural world — has become one of the dominant trends in contemporary architecture. Ottans materials support biophilic principles naturally, bringing organic forms and textures indoors without harvesting more from the natural world. This positions Ottans not just as a sustainable alternative, but as a conceptually coherent material choice for the direction modern design is heading.
