Ottan Materials are developed through bio-based waste streams mostly from agriculture industry such as eggshells, nutshells, agricultural residues, and food-industry by-products. These natural ingredients form the foundation of our circular, design-forward surfaces.

We use only the highest-quality resins that are VOC-free, formaldehyde-free, and toxin-free. The plant-based ratio of our binders varies by product line: Core Line & Seasonal Line: up to 50% bio-resins Stone Line: 35–65% plant-based binders Acoustic Line: up to 100% bio-derived resin We continuously develop our materials to be more sustainable while matching the industry standards in durabilities. These ratios provide the latest state of our developments’ optimal balance for performance, durability, and sustainability across applications.

No. Ottan Materials have no residual odor — unless a specific scent is intentionally requested.

Depending on the material, Ottan Materials consists of 60% to 95% waste by weight.

Yes. Ottan Materials are fully solvent-free and non-toxic. However, we emphasise that our products contain natural ingredients such as hazelnut shells, pistachio shells, and other agricultural by-products, which may not be suitable for individuals with severe nut allergies.

Yes, Ottan Materials are designed with circularity in it’s core. If a surface can not be repaired or repurposed, they can be recycled back to new Ottan materials through our take-back program, ensuring materials remain in continuous circulation.
