[New Materials] Circul’Egg: Recycled and Bio-Based Calcium Carbonate for a Sustainable Industry

Circul’Egg transforms eggshells into CARBIO, a 100% recycled, bio-based, and decarbonized calcium carbonate, ideal for sustainable plastics and packaging.

A circular innovation for sustainable materials

Circul’Egg upcycles co-products from the agri-food industry, starting with eggshells—a material rich in natural resources.Thanks to a patented process, we recover and transform these co-products into sustainable, safe, and innovative ingredients.

More specifically, we produce CARBIO, the only calcium carbonate that is 100% recycled, 100% bio-based, and decarbonized.

This powder integrates seamlessly as a filler in plastics, packaging, and much more. It delivers optimal technical performance while significantly reducing environmental impact.

CARBIO: A high-performance, recycled, and decarbonized alternative

CARBIO meets regulatory requirements, addresses environmental challenges, and responds to the growing consumer demand for more responsible solutions.
