The construction sector is the largest consumer of calcium sulfate. It is used extensively in producing plaster of Paris, cement additives, drywall panels, and floor underlayments. Increasing construction of residential, commercial, and industrial buildings around the world continues to boost product demand. Countries like China, India, and Indonesia are witnessing massive urban development projects, leading to a higher consumption of gypsum-based construction materials. Additionally, calcium sulfate provides benefits such as improved strength, fire resistance, and durability, making it a preferred choice for builders.

Expanding Agricultural Applications
Calcium sulfate plays a key role in improving soil health and crop productivity. Farmers use it to enhance soil structure, reduce compaction, and increase water infiltration. It also helps in supplying calcium and sulfur, both essential for plant growth. With the growing emphasis on sustainable farming and soil conservation, the use of calcium sulfate as a natural soil conditioner is increasing globally. Its ability to reduce salinity and improve nutrient absorption further strengthens its position in modern agriculture.

Shift Toward Sustainable and Eco-Friendly Materials
Environmental regulations and the growing preference for sustainable materials are driving the demand for recycled and synthetic gypsum. The use of calcium sulfate derived from industrial by-products, such as flue gas desulfurization, supports circular economy initiatives. As governments and industries commit to reducing carbon footprints, the sustainable production and utilization of calcium sulfate are gaining prominence in both construction and agricultural applications.

Growing Demand in Pharmaceuticals and Food Processing
High-purity calcium sulfate is widely used as an excipient in pharmaceutical formulations and as a food additive in various products. It serves as a coagulant in tofu production, a stabilizer in canned foods, and a calcium supplement in dietary products. The growing health-conscious population and the increasing use of fortified food items have further expanded this application segment. The pharmaceutical sector also benefits from calcium sulfate's biocompatibility, making it suitable for controlled drug release systems and medical-grade fillers.

Industrial Diversification and Technological Advancement
Technological improvements have led to the development of new forms and grades of calcium sulfate suited for different applications. Granular, powdered, and microcrystalline forms are now available, each offering specific advantages in handling and performance. In addition, innovations in manufacturing processes have improved product purity and consistency, opening new opportunities in high-end industries such as electronics, ceramics, and specialty chemicals.
