Our Coques, Fruits et Noyaux range has been developed using by-products from olives, grape seeds, hazelnuts, almonds, cocoa and eggs. By valorizing these natural residues, these blends combine innovation and performance within acircular economy framework.
Shells and cores, rich in lignin and natural fibers, provide biocomposites with enhanced mechanical properties, such as improved tensile strength. Their incorporation into polymers also confers an organic aesthetic, ideal for a variety of applications, from cosmetic packaging to design objects, technical or decorative parts.
Properties
- Partially to totally biobased
- Biodegradable and compostable depending on matrix
- Natural look
The table below is just an example, and there are many other references that have already been tested or that can be developed for your needs!
