CaCO₃ Market: Who Buys Your Carbon

Published June 202510 min readMarket Analysis

When you mineralize CO₂, you don't just get tax credits — you get a high-purity, sellable product. Calcium Carbonate (CaCO₃) is used across paper, paints, plastics, pharma, and cosmetics. The 98% purity, 96.4% brightness, d50=4µm CaCO₃ produced by Carbon to Crystals qualifies as premium precipitated calcium carbonate (PCC) for the most demanding industrial markets.

Major Buyers & Markets

Paper Manufacturers

PCC is the primary filler and coating pigment for paper production. Major buyers include International Paper, Georgia-Pacific, and UPM-Kymmene. Premium specs (98%+ purity, d50=4µm) command $700–$850/ton for coating-grade applications.

Paints & Coatings

CaCO₃ is the #1 volume filler in architectural and industrial coatings. Buyers include AkzoNobel, PPG, Sherwin-Williams, and BASF. Particle size distribution (d50=4µm) is critical for rheology and film properties.

Plastics & Polymers

CaCO₃ filler reduces raw material costs and improves mechanical properties in PVC, PP, and PE. Major buyers include LyondellBasell, Dow, and Covestro. Volume demand is the largest of any PCC application segment.

Pharmaceuticals

Pharma-grade CaCO₃ requires USP compliance and rigorous purity controls. Used as a calcium supplement, tablet filler, and antacid. Premium pricing of $700–$850/ton for pharmaceutical-grade material.
