Travertine Technologies

Travertine Technologies is an industrial technology company developing processes to produce critical minerals and chemicals while reducing industrial waste and carbon emissions. The company’s work centers on electrochemical processing that connects mineral extraction with carbon dioxide removal and the production of materials for construction. It describes its goal as extracting more value from ore while making critical-element production cleaner and more sustainable.

Travertine was founded in 2022 by Laura Lammers, a former University of California, Berkeley geochemistry professor, and Owen Cadwalader, an environmental engineer and startup operator. The company says its technology grew from research in Lammers’s Berkeley laboratory. Its process draws inspiration from natural rock weathering and is intended to eliminate sulfate byproducts, including phosphogypsum, while permanently storing captured carbon dioxide in mineral products.

The company’s initial focus includes phosphate processing and purified phosphoric acid. Travertine identifies potential uses for purified phosphoric acid in fertilizer, food and beverage applications, water treatment, and lithium-iron-phosphate batteries. Its technology is designed to convert sulfate waste into sulfuric acid and valuable mineral co-products, with sulfuric acid supporting the extraction of critical elements such as phosphorus, lithium, and copper.

Travertine also develops cementitious materials from mineral-processing waste. The company says its process can convert gypsum waste into calcium carbonate or slaked lime for use in concrete and cement, creating a potential link between the phosphate and construction industries. It also describes carbon dioxide capture and mineralization as part of its process, and offers carbon removal credits subject to independent verification under Isometric’s Direct Air Capture protocol.

Travertine reports that it operates an engineering, analytical, and research, development, and demonstration facility at its Boulder headquarters, as well as a demonstration plant in upstate New York. Its Boulder facility supports work in electrochemistry, separations, phosphoric acid production and purification, and integrated process testing. The company is developing its technology toward commercial-scale deployment and works across minerals, cement, and fertilizer industries.

The company’s careers materials describe a team of scientists, engineers, and operators working to turn industrial technology into practical climate and manufacturing applications. Its stated values include planning for safety, prioritizing progress over perfection, being driven by its mission, combining teamwork with individual responsibility, and being honest, curious, and kind. These values reflect the documented emphasis on safety and cross-functional technical work in its research and operating facilities.

Travertine is headquartered at 5311 Western Avenue, Suite 100, Boulder, Colorado. The company presents its work as an effort to address industrial waste and supply needs for critical materials while enabling lower-carbon production and permanent carbon storage. Its public materials describe a development path from laboratory research through pilot and demonstration operations toward commercial chemical production.
