CALCOVO™ is a sustainable calcium carbonate powder derived from industrial eggshell waste. Using Circul’Egg’s patented, fully mechanical separation and fine-grinding process, the outer eggshell is transformed into a high-purity, bio-based CaCO₃ substitute for quarry-mined minerals. Free from chemical additives, CALCOVO™ offers industries a low-carbon alternative, reducing CO₂ emissions by up to fourteen times versus traditional extraction. Its whiteness, inertness, and particle uniformity make it ideal as a filler in materials for construction (e.g. cool-roof paints that reduce building interior temperature by up to 6 °C), nutraceutical capsules, animal feed, and sustainable biocomposites. Because it is sourced locally from eggshell suppliers in France, it supports shorter supply chains and regional job creation. CALCOVO™ responds to rising demand for biosourced, circular ingredients within sectors such as cosmetics, construction, pet food, and food supplements, enabling companies to improve their environmental footprint while maintaining product performance and compliance with eco-regulations.
