WHAT WE DO!
KUORI transforms tomorrow’s materials today—bridging innovation and sustainability without compromise. Our biodegradable BIOWA grades upcycle olive pits and nutshells into high-performance products, reducing microplastic pollution. With Material B, we are developing a 100% bio-based material that naturally returns to the earth, while our patent-pending vulcanized rubber, Material C, will regenerate through chemical recycling. No landfills, no legacy just smarter materials engineered to protect the planet while outperforming the status quo. Explore how KUORI redefines what’s possible when science meets circularity.

5. END OF LIFE - Products
At the end of its life, the product can be melted down and reshaped into new products, drastically reducing waste. By returning the material to its malleable state, we extend material's lifespan and contribute to a more sustainable manufacturing process.
KUORI is using 2nd generation bio-fillers such as walnut shells & olive pits, by-products of the food industry, blended with biopolymers and green additives to create sustainable materials.
1. SOURCE
4. END OF LIFE - Microplastics
Due to their chemical structure, microplastics released by the abrasion of the material will disappear by the action of water and enzymes activity.
2. RESEARCH
Our team of material scientists develops customized grades tailored to client specifications, collaborating with companies to optimize properties such as color, foaming and mechanical properties.
The resulting high-quality pellets are designed for traditional plastic manufacturing processes like extrusion, injection molding and 3D printing, offering an eco-friendly alternative to conventional plastics for shoe soles, outdoor and mobility applications.

OUR STORY
Founded in 2022, KUORI's mission is clear: to break free from the world's dependence on oil-based plastics. Rather than accepting the conventional path, we asked ourselves a daring question: "What if we could drastically reduce microplastic pollution?" It is a significant question, but it is essential to push boundaries to drive real change.
Our journey began with an unconventional idea: upcycling food byproducts like olive pits, walnut shells, and banana peels into innovative, biobased, biodegradable elastic materials. Imagine a material that is not only environmentally friendly but also rivals the utility of conventional plastics, all while seamlessly integrating into existing manufacturing systems.
At our Swiss headquarters and research center, we merge Swiss quality with creative innovation. Our philosophy is simple yet transformative: circularity by design and eco-effectiveness. Every material we develop is biobased and biodegradable because settling for less isn't an option when the stakes are this high.
This unique positioning has set us on a path to becoming a multi-million company in the coming years, proving that the market is ready for sustainable innovation.
