From Waste to Value - Extracting Valuable Resources
At Lithium Harvest, we’re turning a costly byproduct into a valuable, multi-use asset. Our patented Direct Lithium Extraction (DLE) technology, combined with advanced water treatment, transforms lithium-rich brines into new sources of revenue and sustainability.
We use our proprietary DLE system in synergy with decades of water treatment expertise to unlock the hidden potential of produced water from oil and gas operations, geothermal brines, and other lithium-bearing fluids. The result? Reduced scaling, improved uptime, and higher extraction performance - built for real-world conditions.
By bringing together leading-edge extraction and water treatment, we’re redefining brine management. What used to be waste or byproducts is now a strategic resource with far-reaching environmental and economic value.
Our five-step process ensures efficient resource extraction and repurposing:
- Collection: Brines are collected directly from oil wells, midstream infrastructure, or geothermal operations, laying the foundation for transformation.
- Filtration and separation: Advanced systems remove solids, hydrocarbons, heavy metals, and contaminants from the brine to prepare it for extraction.
- Advanced water treatment: Using innovative, proven technologies, the purified water undergoes further treatment to meet stringent quality standards for resource extraction and production efficiency.
- Resource extraction: Critical minerals like lithium are extracted and refined, turning waste into value and fueling the green energy transition.
- Repurposing: Cleaned water can be reused for sustainable applications, such as freshwater supply, agriculture, industrial use, reservoir reinjection, or other ESG-aligned initiatives.
This future-ready process turns lithium-rich brines into dual assets, supporting environmental stewardship and economic growth.
At Lithium Harvest, we’re helping our partners meet ESG goals, unlock new revenue, and lead the next generation of sustainable mineral production.
From Concept to Reality - See Our Technology in Action
In this short video from CERAWeek 2025, CEO Sune Mathiesen explains how Lithium Harvest is redefining lithium extraction.

Lithium Harvest vs. Traditional Lithium Mining
Fun Fact (That’s Also a Little Alarming)
Did you know traditional lithium mining is incredibly resource-intensive? It can consume millions of gallons of water - enough to fill hundreds of Olympic-sized swimming pools - and release vast amounts of CO₂ into the atmosphere.
At Lithium Harvest, we do things differently.
By using produced water and geothermal brine as feedstock, we help meet global lithium demand without the environmental cost.
Here’s the difference we make with every 1,000 metric tons of lithium carbonate produced:
- 20.4 million kg of CO₂ saved - that’s like taking ~4,435 cars off the road for a full year.
- 96.1 million gallons of water conserved - enough to fill ~146 Olympic swimming pools or meet the annual water needs of ~880 U.S. households.
- No evaporation ponds. No land disruption - Our closed-loop process recycles over 90% of the water used.
And we’re just getting started.
The world will need millions of tons of lithium in the coming decades. That’s a lot of water, carbon, and waste saved - or not.
Something to think about.
We don’t generate new waste. We turn existing waste into value, producing battery-grade lithium from what used to be a disposal problem.
Every drop counts. Every ton makes a difference.
One Technology. Multiple Industries. Maximum Impact.
