Ottan materials are engineered from upcycled organic by-products such as eggshells, pistachio and hazelnut shells, expired grains, fruit peels, leaves and grass, each contributing to distinctive natural colours and textures without added colourants. They are available across multiple lines—including Core, Seasonal, Translucent, Acoustic and Stone collections—offering designers options from warm wood-like surfaces and smooth neutrals to acoustic panels and textured finishes.

These materials exhibit natural durability, chemical resistance and visual character, with performance attributes that can be enhanced through surface finishing and coatings. Applications include wall cladding, furniture, interiors, acoustic solutions and bespoke design elements, making OTTAN a versatile choice for both commercial and residential settings.

Sustainability is central to OTTAN’s mission: by upcycling high-volume organic waste streams, reducing extraction of new resources, and supporting circular economy thinking, the brand contributes to lower environmental impact and responsible material use.

As part of the MTRL Library, OTTAN invites designers and specifiers to explore its bio-composite materials firsthand—engaging with texture, colour variation and material story in a hands-on, tactile setting. This early-stage exploration supports informed and thoughtful specification, connecting creative intent with sustainable performance.
