Calcium Sulfate Market Report 2025 (Global Edition)

Market Dynamics 

Key Drivers 

• High demand for Calcium Sulfate in the Paper Industry is boosting the market growth 

Increasing demand for Calcium Sulfate Consumption products and services, fueled by factors such as population growth, urbanization, and changing consumer preferences, is a significant driver for market expansion. The need and desire for extremely bright paper in recent years has compelled paper producers to come up with innovative strategies for raising coated paper's brightness and whiteness. Pigment coating is a commonly employed technique to improve the optical characteristics of paper and paperboard, including brightness, whiteness, and gloss. These optical characteristics, which also affect coated paper's ultimate cost, are the most significant to end users. When it comes to optical qualities, calcium sulfate is superior to other common pigments like kaolin clay, precipitated calcium carbonate, and powdered calcium carbonate. The outcomes also showed that coated paper with excellent brightness and whiteness may be made by using calcium sulfate as a pigment. For instance, in 2023, Specialty paper manufacturer, Nordic Paper announced its plans to invest $78 million at the Bäckhammar pulp and paper production mill in Värmland, Sweden. Thus, this will include the use of calcium sulfate in the production of paper. The growing paper industry will require more calcium sulfate as a surface sizing agent thus increasing the demand for the Market.

• The robust demand from the agriculture industry has resulted in the growth of the market

The Agriculture industry has contributed significantly to the Global Calcium sulfate market growth. This is due to the increasing When calcium sulfate being applied to soil, Ca2+ ions in the form of chemically neutral salt are available to plants, especially to the species with a high demand for calcium sulfate. Calcium sulfate is also a rich source of sulfur that plants can easily access. It has a positive influence on the volume and quality of the yield of plants with high demand. Calcium sulfate affects plant growth and yield quality. When used as a fertilizer, it directly supplies sulfur and calcium to plants. Calcium sulfate introduced into soil as a chemically neutral salt does not form concentrated solutions and its pH is almost neutral. As a result, it does not damage leaves and it can be safely used for top dressing, even as a dust fertilizer. Calcium sulfate fertilization has positive effects on heavy clay soils because it increases the rate of water infiltration and reduces the crust on the surface of these soils. When calcium sulfate is applied to the soil solution, complex compounds are formed, which reduce the harmful effect of aluminum on plants. For instance, in 2023, EcoGem launched a product, a Soil Enhancer, infused with Calcium Sulfate Dihydrate, which is a valuable tool in enhancing soil structure and promoting optimal plant nutrition, thereby contributing to improved crop yields.

Restraints

• An adverse effect of calcium sulfate on human health is expected to hamper market expansion

Calcium sulfate is not particularly dangerous. Although, the particles’ physical toughness mainly causes risks. Contact that is prolonged or repeated might irritate the eyes and skin. Irritation of the throat and nose from breathing in anhydrite particles can result in a sore throat, nosebleeds, and shortness of breath. This can hinder the Global Calcium Sulfate Market growth.  When it comes to chemicals, calcium sulfate is comparatively safe. The particles' physical hardness is mostly to blame for any risks. Skin and eyes can get irritated by prolonged or repeated contact. Shortness of breath, nosebleeds, and sore throats can all result from breathing in anhydrite particles, which irritate the nose and throat. Additionally, it can lead to pulmonary nodular fibrosis. Constipation and impaired iron and zinc absorption are two side effects of its high ingestion. Processing and using gypsum can expose workers to silica and sulfate-containing powdered gypsum dust. Lung conditions including lung cancer and silicosis can be brought on by extended exposure. Employees who work in mining, crushing, or plasterboard cutting are more vulnerable. Producers incur additional expenses when worker safety standards are put into place during the manufacture of gypsum products. Growth in the industry is somewhat constrained by the health risks connected to gypsum dust. Additionally, calcium sulfate in supplement form increases the risk of kidney stones, cardiovascular disease, and prostate cancer with high intake. Thus, the adverse effect of calcium sulfate on human health is expected to hamper the market growth. People who have certain medical disorders, such as renal illness, diabetes, and hypercalcemia, should take caution and speak with their doctor before using calcium sulfate supplements or eating foods high in calcium sulfate. 

Opportunities 

• Expansion of Calcium sulfate in the healthcare sector will further create lucrative opportunities for the market 

Healthcare Calcium Sulfate, sometimes referred to as gypsum, is used in the pharmaceutical and healthcare industries as a whitening or coloring agent and as a calcium supplement. It is essential for the formation of cells and bones. In addition to being employed as a desiccant in the anhydrite form, it supplies a naturally occurring organic excipient with vital calcium nutrients. Some pharmaceuticals and nutritional supplements are made with calcium sulfate dihydrate. It helps ensure that active medicinal components are properly formulated and delivered by acting as an excipient. In addition to being an affordable, dependable, and safe bone void filler, calcium sulfate may also be used as an absorbable drug delivery system for antibiotics or other substances. For instance, in 2019, Exatech announced its First Successful Surgeries with its product InterSep Calcium Sulfate Bone Void Filler. Designed to completely resorb and replace bone throughout the healing process, InterSep is a bone void filler made entirely of synthetic calcium sulfate. Including infected bone areas, InterSep, which is made in the United States, can be utilized in a range of bone and joint replacement procedures. With its possibilities for bead-and-paste, it gives surgeons versatility. It will need more excellent prospective and randomized clinical trials to determine the function of calcium sulfate in contemporary orthopedics. Calcium sulfate reduces the need for synthetic polymers and other non-organic ingredients by producing an affordable binder, filler, coating, disintegrant, or bulking agent for tablets and capsules. In addition, toothpaste, powders, creams, and other medical supplies include it. In pharmaceuticals, calcium sulfate is used as an excipient in tablet formulations. It acts as a filler and binder, aiding in the formation and stability of tablets. In addition, it is widely used in dentistry practices as casts or dental impression forming tool, which supplements the market growth. Moreover, an increase in the use of calcium sulfate as an inactive ingredient in pharmaceutical drugs and as a desiccant in building materials is expected to fuel the growth of the market. Due to the increasing prevalence of bone disorders like osteoporosis and the aging population globally, orthopedic implant demand is expected to skyrocket in the upcoming years, offering lucrative growth opportunities for industry players. Furthermore, the market is expected to grow over time as a result of the growing use of calcium sulfate in the production of pharmaceuticals and food additives.

Impact of Covid-19

The COVID-19 pandemic has harmed the calcium sulfate business. The construction, food processing, pharmaceutical, and other industries have reduced their need for calcium sulfate as a result of the lockdown implemented to stop the virus's spread and its accompanying effects on economic activity. As a result, idle capacity has increased for all manufacturers. Furthermore, it is anticipated that supply chain network disruption brought on by lockdowns had an additional impact on the availability and production of raw materials like gypsum, which is needed to make calcium sulfates. Furthermore, during the projected period, businesses operating in this market may have fewer prospects for overall expansion due to travel limitations impeding sales activities. For instance, in 2020, the National Centre for Biotechnology information in a study stated a collaborative investigation found that critical COVID-19 patients had lower calcium concentrations than patients with less severe illness, and it concluded that patient blood calcium levels are negatively correlated with disease severity.
