The compound also finds use as a firming agent and coagulant in the food industry and as a pharmaceutical excipient.

As industrial production continues to evolve toward sustainable practices, calcium sulfate’s eco-friendly and non-toxic properties have positioned it as a preferred material. Manufacturers are increasingly investing in innovative processing technologies to produce high-purity grades suitable for specialized applications such as pharmaceuticals and food manufacturing.

Market Forecast

The market is projected to expand consistently through 2032, driven by infrastructure development and agricultural productivity improvements. From an estimated valuation of US$3.0 billion in 2025, the global market is expected to reach approximately US$4.8 billion by 2032, supported by an annual growth rate of 7.1 percent.

This growth trajectory underscores the expanding role of calcium sulfate as both an industrial and environmental solution. With increasing awareness about sustainable construction and the circular economy, calcium sulfate-based materials are gaining traction across major end-use industries.

Key Market Drivers

Expanding Construction and Infrastructure Projects

The construction industry remains the largest consumer of calcium sulfate, particularly in the form of gypsum boards, plasters, and cements. Rapid urbanization in emerging economies and renovation of existing structures in developed regions are creating sustained demand for calcium sulfate-based products.

Lightweight, fire-resistant, and acoustically effective building materials are increasingly preferred by architects and builders. Calcium sulfate offers these characteristics, making it indispensable for producing high-performance drywall, panels, and flooring materials.

Growing Agricultural Applications

In the agricultural sector, calcium sulfate is widely used to improve soil structure and fertility. It enhances water infiltration, reduces salinity, and supplies essential nutrients such as calcium and sulfur. As global agricultural practices move toward sustainability and soil health restoration, calcium sulfate has gained prominence as a natural and environmentally friendly soil amendment.

Farmers across Asia, North America, and parts of Europe are increasingly using calcium sulfate to rehabilitate degraded soils and boost crop yields. This trend is expected to continue as governments promote sustainable farming techniques.

Rising Use in Food and Pharmaceutical Industries

Calcium sulfate’s role as a safe and effective food additive is another growth driver. It is used as a coagulant in tofu manufacturing, a firming agent in processed foods, and a dietary calcium source in nutritional supplements. In pharmaceuticals, calcium sulfate serves as an excipient, tablet filler, and a material for dental and orthopedic applications.

The demand for high-purity calcium sulfate grades in these industries is growing rapidly as consumers and manufacturers emphasize food safety, product stability, and bio-compatibility.

Cost Efficiency and Resource Availability

Abundant natural gypsum reserves and the increasing availability of synthetic gypsum (derived from industrial processes such as flue-gas desulfurization) are ensuring a steady and cost-effective supply of calcium sulfate. This availability enhances production efficiency and supports competitive pricing for end-use industries.

Regulatory Support for Sustainable Materials

Government initiatives promoting sustainable construction materials and soil management practices are further accelerating the market. Calcium sulfate’s recyclable and non-toxic nature aligns well with global environmental regulations and sustainability goals.
