Question 1

What materials are used to create Ottan products?

Accepted Answer

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.

Question 2

Besides waste, what other materials are included?

Accepted Answer

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.

What percentage of Ottan Materials is made from waste?

Accepted Answer

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

Question 5

Are Ottan Materials solvent-free and non-toxic?

Accepted Answer

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.

Question 6

Are Ottan Materials fully circular?

Accepted Answer

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.
