Eggshell Calcium for Plastics

Eggshell calcium is an upcycled calcium carbonate derived from food-grade eggshells and processed for industrial use. It offers a functional, lower-carbon alternative to mined CaCO₃ for plastic applications.

Used as a mineral filler, eggshell calcium can improve stiffness, dimensional stability, and processing behavior in a range of plastic formulations while maintaining consistent performance.

Eggshell calcium can be incorporated into a variety of polymer systems, including polypropylene and other thermoplastics, making it suitable for multiple end-use applications.

Controlled sourcing and standardized processing deliver predictable particle size and reliable material behavior—critical for compounders and processors that demand repeatability.

 Compared to some traditional mineral fillers, eggshell calcium offers functional mineral content without unnecessary density, supporting material optimization and formulation flexibility.

Eggshell calcium enables the use of upcycled, circular materials in plastic formulations—an increasingly valuable differentiator for brands responding to regulatory pressure and customer demand.

Produced from waste eggshells, this material diverts landfill waste and carries a significantly lower carbon footprint than mined calcium carbonate—helping manufacturers meet sustainability and ESG goals.

  Our process is designed for consistent quality and scalable production, supporting R&D trials today and commercial volumes tomorrow.
