Calcium Sulfate Market Size & Trends

The global calcium sulfate market size was estimated at USD 3,762.9 million in 2024 and is projected to grow at a CAGR of 13.2% from 2025 to 2030. The integration of gypsum production with cement and drywall manufacturing units, allowing economies of scale and captive raw material use, is especially evident in Turkey.

Thailand, and Eastern Europe. Together, these supply-side factors enable natural abundance, regulatory-driven synthetic recovery, and industrial integration, which are reinforcing production resilience and availability of calcium sulphate across both developed and emerging economies.

The production of calcium sulphate, both natural (gypsum) and synthetic (such as FGD gypsum, phosphogypsum), is heavily influenced by geological availability, industrial byproduct recovery infrastructure, and environmental compliance mandates. One of the most prominent production-side drivers is the abundant availability of natural gypsum deposits, especially in countries like China, the U.S., Iran, and India, where large sedimentary reserves enable cost-effective extraction for use across construction, agriculture, and industrial applications. For instance, Rajasthan in India and Iowa in the U.S. are major mining hubs due to shallow gypsum beds and low stripping ratios. Simultaneously, the rise of synthetic gypsum production is significantly tied to expanding coal-fired power plants with flue gas desulfurization (FGD) systems, which convert sulfur dioxide into calcium sulphate dihydrate.

The global expansion of desalination infrastructure, especially in water-scarce regions, is a primary enabler for calcium sulphate recovery from brine. Countries like Saudi Arabia, UAE, Qatar, Oman, and Israel generate vast quantities of high-salinity reject brine as a byproduct of seawater desalination, typically rich in calcium and sulfate ions. Rather than disposing of this brine into the sea (a practice now under environmental scrutiny), several regional initiatives are exploring selective crystallization and precipitation of calcium sulphate (gypsum) as a value-added recovery mechanism.

Drivers, Opportunities & Restraints

Governments in brine-generating regions are increasingly mandating zero liquid discharge (ZLD) or partial brine recovery protocols in industrial and municipal plants. Calcium sulphate crystallization is often one of the earliest and most stable precipitation steps during multi-stage brine treatment, making it a practical entry point into circular resource recovery. In countries like India, ZLD norms are already enforced across textiles and chlor-alkali manufacturing sectors, driving investment in brine evaporation and salt recovery systems.

China’s coastal industrial parks pilot membrane-evaporation hybrids and solar crystallizers, enabling scalable gypsum harvesting from complex brine matrices. As environmental governance strengthens, particularly in the Middle East, South Asia, and parts of North Africa, the compliance-driven recovery of calcium sulphate from brine will become both a legal necessity and an economic advantage.

Globally, most desalination facilities in the Middle East (e.g., UAE, Saudi Arabia), Australia, or Spain are optimized solely for freshwater production and not for mineral recovery from reject brine. As a result, brine is typically discharged into the sea without extracting potentially valuable salts like calcium sulphate. Setting up mineral recovery systems such as selective crystallizers, brine concentrators, or solar evaporation ponds requires capital investment and significant modification of existing plant designs. For example, Saudi Arabia's SWCC has only recently initiated pilot projects to explore mineral recovery from desalination brine, despite being one of the largest desalination operators in the world. The lack of integration between desalination and mineral extraction processes across most global plants is a key bottleneck that restricts the scalability of brine-to-calcium sulphate systems.

The calcium sulfate industry presents significant opportunities driven by increasing demand in coatings, lubricants, and polymers. Growth in the automotive and construction sectors fuels the need for high-performance driers and stabilizers, particularly in eco-friendly and water-based coatings. Rising industrial automation and machinery advancements also boost demand for calcium sulfate in lubricating oils and greases. In addition, the shift toward sustainable and bio-based alternatives presents a key opportunity for innovation. Emerging markets in Asia-Pacific and Latin America offer further growth potential due to expanding manufacturing and infrastructure development.

Application Insights

During the forecast period, the industrial segment dominated the market with a market share of 39.9% in 2024. The industrial segment in the calcium sulfate industry is driven by its use in applications such as cement production, ceramics, paper manufacturing, and chemical processing.
