Stardust Power has confirmed that its Oklahoma lithium facility will not require an industrial wastewater discharge permit, due to the implementation of a closed-loop water system.
The company’s decision marks a strategic environmental and regulatory milestone. By recycling water internally, Stardust Power eliminates the need for discharge into public systems or natural waterways—an uncommon feat in U.S.-based lithium operations. This proactive design reduces regulatory burdens and supports the company’s broader commitment to sustainable lithium production.
Closed-Loop System Enables Regulatory Efficiency
Stardust Power’s Oklahoma lithium facility is designed to operate with minimal freshwater use after initial commissioning. Tanks are filled once and reused in an ongoing loop, effectively removing the need for continuous water extraction or wastewater discharge.
“Not requiring a water permit speaks to how clean a facility we have designed,” said Roshan Pujari, CEO and founder of Stardust Power. “Our closed-loop system significantly reduces water needs and discharge volumes. Unlike some operations that place heavy demands on local water resources, we’re delivering a scalable, sustainable solution.”
This system not only streamlines the regulatory process—avoiding lengthy wastewater permitting—but also reduces costs and shortens project timelines. The ability to bypass municipal treatment infrastructure also preserves public water supplies, a growing concern in resource-constrained regions.
Broader Permitting Progress for Stardust Power
The closed-loop breakthrough follows other permitting wins for Stardust Power’s Oklahoma lithium facility. The company has already secured the General Permit for Stormwater Discharges from Construction Activities from the Oklahoma Department of Environmental Quality (ODEQ), allowing site construction to proceed. Stardust has also finalized its Stormwater Pollution Prevention Plan (SWPPP), incorporating advanced runoff management to safeguard local ecosystems.

In addition, the company’s Minor Source Air Permit has been deemed administratively complete and is now under technical review by ODEQ. According to company officials, all interactions with state regulators remain active, with responsive engagement across ongoing review phases.
Environmental Stewardship in Lithium Manufacturing
Stardust Power sources lithium from brines—a less water-intensive method compared to hard rock mining—and prioritizes internal water reuse throughout its operations. The Oklahoma lithium facility will reflect this approach, setting a benchmark for domestic clean energy supply chains.
“Water is a finite and shared resource,” said Pujari. “We’re not just building a plant—we’re building a responsible infrastructure that supports decarbonization without compromising local water availability.”
From exploration to extraction, the company integrates conservation and reuse principles. Its system aligns with best practices outlined by international agencies such as the International Energy Agency (IEA) and avoids the evaporation ponds and tailings dams often associated with high-impact lithium operations.
A Permitting Edge Amid Rising Demand
With U.S. lithium demand accelerating under the Inflation Reduction Act and global battery markets, fast-tracking project timelines is a competitive imperative. The Oklahoma lithium facility’s ability to circumvent wastewater permitting gives Stardust Power a critical edge over rivals mired in regulatory red tape.
For Oklahoma, the facility represents a clean-tech investment model that balances energy security with community stewardship. And for Stardust Power, it reinforces the company’s position as a leader in next-generation lithium refining—with sustainability at its core.
