Calcium carbonate or its PCC and GCC forms are obtained both processed, and delivered to the market as fillers and extenders in various industries like paper, plastic, paint and coating, construction, and even in pharmaceuticals and agriculture. The very high quality, brightness, and low cost of the material are the main reasons for its widespread use as a functional filler, additive, and pigment in many industries. Adoption is accelerated by government initiatives: Nigeria's December 2024 IzeCarb facility under federal support reduces imports; Ethiopia's May 2025 opening of MIDROC's coated GCC plant increases local pharma and plastics supply; and Saudi Arabia's 2025 high-purity GCC project by the Water Authority advances water treatment self-sufficiency.
