Sustainable Projects Group (SPGX) is a pre-revenue lithium company developing a Direct Lithium Extraction (DLE) technology to extract battery-grade lithium compounds from oilfield wastewater, also called produced water. SPGX's two planned products are lithium carbonate and lithium hydroxide, both key inputs in lithium-ion batteries, which SPGX intends to sell directly to EV and battery manufacturers. SPGX acquired the core DLE technology via its February 2023 purchase of Lithium Harvest, a Danish private company. SPGX's first two facilities are planned for North Dakota and Ohio, with a combined capacity of up to 2,000 metric tons of lithium carbonate equivalent (LCE). SPGX argues its approach is cost-advantaged vs. traditional mining because produced water is essentially a waste product, eliminating the need to acquire land or drilling permits. SPGX also argues its DLE process takes hours vs. years for conventional brine evaporation, and that extracting lithium from wastewater gives it a lower environmental footprint — a selling point with EV manufacturers facing supply chain scrutiny. SPGX holds a Danish patent on its DLE technology expiring in 2032, with a U.S. and international patent pending. Longer term, SPGX targets ~6,000 metric tons of LCE capacity by end of 2026, and plans to expand beyond lithium to extract nickel, magnesium, and vanadium from produced water. SPGX has no facilities, no revenue, and only 14 full-time employees, and its business model remains entirely unproven at commercial scale.
