Market Outlook: 2025–2035

The global bentonite market is projected to increase from USD 2.5 billion in 2025 to USD 4.3 billion by 2035, with a CAGR of 5.2%, driven by increased demand in the construction, iron ore pelletizing, oil and gas, wastewater treatment, and foundry industries. Their use makes them ideal for binding, sealing, and lubricating applications across various industries, including mining, construction, and drilling.

Drivers of this growth include:

Construction boom: Driven by a global rise in infrastructure projects—tunneling, subways, and high-rise foundations.
Iron ore pelletizing: Critical in steelmaking; bentonite acts as a key binder.
Oil & gas expansion: Especially in shale and offshore regions, where demanding drilling conditions prevail.
Wastewater and landfill sealing: Tightened environmental regulations promoting bentonite-based liners.
Foundry recovery: Revived metal casting activity demands consistent bentonite for mold stability.
This wide industrial demand profile cements bentonite’s critical role as a binding, sealing, and lubricating agent in industries like mining, construction, and drilling.

Regional Insights

Asia-Pacific: The largest market, with China, India, and Southeast Asia leading. Urbanization, steel production, and infrastructure development propel demand. India, rich in both sodium and calcium bentonite, harnesses domestic supplies for construction and drilling.
North America: The U.S. remains a leading producer—especially from Wyoming—for sodium bentonite. Demand is driven by drilling activities in shale regions like the Permian and Bakken basins, along with construction and environmental containment projects.
