Kuori WAB N1

Positive Plastics KIT3

What is it?

A bio-based and biodegradable elastic material based on food waste such as banana peels and nut shells. This grade is a thermoplastic elastomer compound for injection moulding applications. It can also be processed by pressing, 3D printing, or foaming, like conventional thermoplastics. 

The mechanical characteristic properties shown here were determined by the Institute of Polymer Engineering of Applied Sciences Northwestern Switzerland on injection-moulded standardized test specimens.
Delivered in its natural colour, yellow-brown, KUORI’s  colours can also be customised to customer preferences. Available worldwide.

Technical benefits

This bio-based and biodegradable material is elastic and serves as an alternative to conventional elastomers. 


Look and feel

The inclusion of banana peels and nut shells, creates natural patterning and coloring. Moreover, the material can be dyed, engraved, printed upon, polished, sandblasted and more (Post-processing).


Environmental benefits

KUORI materials are industrially compostable and can break down within 90 days. Microplastics derived from this material can naturally biodegrade without releasing harmful substances into the environment. Production also uses food byproducts that otherwise would be discarded.



This material can be applied in various industries: fashion, outdoor, and toys, for example. The company is actively engaged in dynamic pilot projects with other companies to refine and adapt its material to suit new applications.
