Who We Are - Investor View
Built to build. End-to-end water-to-lithium execution with proven industrial experience.
Sustainable Lithium Extraction
What if the cleanest lithium didn’t come from a distant, high-cost mine?
At Lithium Harvest, we are pioneering sustainable lithium extraction right at the source. Our patented solution turns oilfield wastewater and geothermal brine into battery-grade lithium - faster, cleaner, and more cost-effectively than traditional mining - supplying the rapidly growing EV and battery markets.
- Fastest-to-market: Online in 12-18 months vs an average of 14 years for traditional mines.
- The world’s most sustainable lithium: Carbon-neutral, no pits, no ponds - waste to value.
- Lowest costs: Up to 73% lower CapEx and 48% lower OpEx.

Our Story
Solving a decade-old waste problem - and scaling to revenue inside five years.
Lithium Harvest began as a field insight in 2012, when founders Sune Mathiesen and Paw Juul were running a produced-water treatment pilot for a major oil and gas company. Produced water - usually disposed as a waste stream of oil, solids, salts, and chemicals - revealed an overlooked resource: valuable minerals, including lithium, ready to be recovered. That discovery sparked a decade of R&D and laid the groundwork for a breakthrough in sustainable lithium extraction.
By 2020, the duo formalized the venture and channeled two decades of industrial-water experience (400+ plants delivered) into a patented lithium extraction platform. In 2023, Lithium Harvest completed a reverse merger with Sustainable Projects Group, Inc. (OTC: SPGX), becoming a wholly owned operating subsidiary and the group’s technology center. The same year, the core patent family was granted, and public listing on the OTC market provided both IP protection and access to capital markets.
With its core technologies validated, Lithium Harvest is now transitioning from concept to its first 8,338t LCE/yr (at full scale) commercial units, scheduled to start up in 2027 - the catalyst that will convert the company from a pre-revenue story to a cash-generating producer.
