According to a new report from Intel Market Research, global Calcium Sulfate market was valued at US$ 6,297 million in 2025 and is projected to reach US$ 7,185 million by 2032, growing at a steady CAGR of 1.9% during the forecast period (2025–2032). This sustained growth is propelled by robust demand from the construction sector, coupled with its expanding use as a functional ingredient in food and pharmaceuticals, reflecting its versatility and established industrial footprint.
Calcium Sulfate is the inorganic compound with the formula CaSO4 and its related hydrates. It is more commonly known as gypsum, a mineral sourced directly from gypsum mines. The material's significance stems from its unique properties, including fire resistance and binding capabilities. Calcium sulfate's most prominent application is in the construction industry, where it serves as the primary component for gypsum wallboard and plasterboard, which are essential for modern building interiors.
Beyond construction, calcium sulfate demonstrates remarkable versatility. It is widely utilized as a filler and conditioner in numerous food products and is an excipient in pharmaceutical formulations, underpinning its stable demand across diverse, non-cyclical end-markets.

1. Global Construction Boom and Urbanization
The relentless pace of global urbanization, particularly in emerging economies, is a fundamental driver for the calcium sulfate market. The global construction output is projected to grow by 42% to $15.2 trillion worldwide by 2030, creating immense demand for cost-effective and code-compliant building materials like gypsum board. This is because gypsum wallboard is not only economical but also offers critical fire-resistant properties, making it a mandatory material in many residential and commercial building codes. Furthermore, the rising trend towards drywall construction over traditional wet plaster methods further accelerates adoption due to faster installation times and reduced labor costs.
2. Expanding Applications in Food and Industrial Sectors
While construction remains the dominant consumer, calcium sulfate is gaining significant traction in other sectors. Its non-toxic nature and functional properties make it an ideal additive, leading to its investigation and use in a broader spectrum of applications.
Food Industry: It is extensively used as a calcium fortifier, coagulant in tofu production, and a dough conditioner in baked goods.
Pharmaceutical Industry: Serves as a stable inert diluent in tablet formulations.
Agriculture: Used as a soil conditioner to improve water infiltration and provide essential calcium and sulfur nutrients.
This diversification beyond its core construction application positions calcium sulfate as a multipurpose industrial mineral with resilient, long-term demand drivers.
Volatility in Raw Material and Energy Costs: The energy-intensive process of calcining gypsum into plaster of Paris makes the industry sensitive to fluctuations in energy prices, which can squeeze profit margins.
Environmental Regulations: Quarrying operations and manufacturing processes are subject to stringent environmental regulations concerning dust control, water usage, and greenhouse gas emissions, potentially increasing operational costs.
Competition from Substitutes: In certain applications, such as soil conditioning or industrial fillers, calcium sulfate faces competition from alternative materials like lime or synthetic compounds.
The market is witnessing a strategic shift toward value-added products and sustainable practices. Regions with developing industrial bases, such as Asia-Pacific and Latin America, present significant growth avenues driven by:
Technological Advancements: Development of alpha-hemihydrate plasters, which offer superior strength and hardness, represent a key growth frontier.
Circular Economy Initiatives: Increased use of synthetic gypsum (e.g., flue gas desulfurization gypsum) which promotes waste valorization from power plants.
Strategic Expansion into Niche Markets: Including advanced medical casts and 3D printing materials.
Notably, major industry participants are actively pursuing expansion and innovation. For instance, Saint-Gobain has been focusing on developing lighter-weight and more durable wallboard products to meet evolving construction standards and customer preferences for sustainable building materials.
China and Europe: Collectively dominate the global landscape, accounting for approximately 45% of the total market, driven by established construction sectors and manufacturing capabilities.
North America: Maintains a significant market share supported by a robust housing sector, renovation activities, and well-defined building codes mandating fire-resistant materials.
Asia-Pacific: is identified as the highest growth potential region, fueled by massive infrastructure development and rapid urbanization.
