Calcium Sulfate Market Analysis: Size, Segmentation, and Growth Forecast (2025–2034)

The global calcium sulfate market is entering a decade of sustained expansion, driven by structural demand across construction, food processing, pharmaceuticals, and agriculture. According to Polaris Market Research, the market was valued at USD 3,697.75 million in 2024 and is projected to reach USD 4,169.88 million in 2025, before climbing to USD 12,379.11 million by 2034   a CAGR of 12.9% across the 2025–2034 forecast period.

Market Size and Structural Drivers

Two structural forces underpin this growth. First, industrial byproduct recycling: synthetic gypsum, largely derived from flue-gas desulfurization processes, accounted for approximately 15 million tons   or 33% of total US gypsum supply   in 2023. This diversification of supply sources improves scalability and cost stability for manufacturers. Second, sustainable material mandates are pushing both construction and agriculture toward calcium sulfate-based alternatives, supported by regulatory tailwinds in developed markets and infrastructure expansion in emerging ones.

Segmentation: Product Type

By product type, the market splits into gypsum (natural and synthetic) and anhydrite (natural and synthetic). Gypsum is expected to post the fastest growth over the forecast period, underpinned by its dominant role in drywall, plaster, and cement board manufacturing, along with secondary applications in agriculture and orthopedic medical casts. The push toward lightweight, energy-efficient building materials continues to reinforce gypsum's segment leadership.

Segmentation: Grade

The market is further segmented by grade into technical, food, pharma, and other grades. Food-grade calcium sulfate is expected to see substantial growth, driven by its multifunctional role as a firming agent, dough conditioner, and calcium supplement in bakery items, canned vegetables, and tofu. Regulatory approvals across major markets provide a stable foundation for consistent demand, particularly as clean-label formulation trends accelerate globally.

Segmentation: End-Use Industry

Segmented by end-use industry   food and beverages, cosmetics and personal care, building and construction, chemical and petrochemical, pulp and paper, agriculture, pharmaceutical and healthcare, and others   the building and construction segment dominated in 2024. This dominance stems from extensive use in wallboards, plasters, and flooring systems, supported by fire-resistant and insulating properties that align well with modern green building standards, particularly in high-growth developing economies.

Regional Breakdown

• Asia Pacific led the market in 2024, driven by construction activity, expanding food processing, and rising agricultural adoption in China and India. Vietnam's fertilizer consumption runs at roughly three times the global average, split between 75% chemical and 25% organic fertilizers, reflecting strong regional appetite for soil-improvement inputs like gypsum.
• North America is projected for substantial growth, supported by advanced infrastructure, mature pharmaceutical formulation industries, and rising precision-agriculture adoption   auto-steering systems were used on 52% of midsize and 70% of large US farms in 2023, enabling more efficient calcium sulfate application in soil management.
• Europe is expected to grow steadily, propelled by sustainable construction mandates and clean-label food additive adoption, with Germany, France, Italy, and the UK as key contributors.

Competitive Landscape

Key players shaping the competitive environment include BASF, Saint-Gobain, Knauf Group, LafargeHolcim, USG Corporation, GMCI, Foodchem International Corporation, and XI'AN FUNCTION MATERIAL GROUP CO., LTD., among others. Recent developments underscore the sector's direction:

• In September 2025, Sika AG launched a sustainable line of calcium sulphate-based construction products.
• In October 2025, BASF partnered with an agricultural firm to develop calcium sulphate fertilizers targeting improved crop yields.
• In April 2025, SUL4R-PLUS opened a new 100,000-ton-per-year calcium sulphate fertilizer plant in Marissa, Illinois, repurposing an old industrial site to supply regional farmers.
• In October 2023, Saint-Gobain expanded into Sub-Saharan Africa through its acquisition of Global Gypsum Company.

Outlook

With a forecast CAGR of 12.9% through 2034, the calcium sulfate market's growth is broad-based rather than concentrated in a single vertical. Construction remains the largest end-use segment, but food-grade and agricultural applications are scaling quickly, supported by regulatory, environmental, and productivity-driven demand. Companies positioned across multiple grades and regions   rather than single-application specialists   appear best placed to capture the market's expanding value pool over the next decade.
