About the company:

Travertine is a green technology company developing next-generation phosphate processing technology that is circular, carbon-negative, and designed to extract more value from phosphate ore. Their proprietary process produces purified phosphoric acid and cementitious materials as primary outputs, replacing the traditional wet-acid phosphate process that generates large volumes of phosphogypsum waste. By transforming gypsum byproducts into calcium carbonate or slaked lime usable in concrete and cement, Travertine closes the loop between the fertilizer and cement industries, enabling more sustainable production across both sectors.

About Travertine

Travertine is an Industrial Transformation company based in Boulder, CO, that is rapidly scaling a technology for sulfur-decoupled production of critical minerals, starting with phosphate. Our technology enables large-scale circularity in extractive industries while simultaneously decarbonizing building materials. We do this by electrochemically recycling chemical byproducts, sulfate wastes, into sulfuric acid and valuable mineral co-products.

Sulfuric acid is the world's most used inorganic chemical and is vital for producing a wide range of critical elements including phosphate, lithium, copper, nickel, and rare earth elements. Travertine's technology solves the dual problems of sulfur supply vulnerability and large-scale chemical waste disposal. Our transformative process changes the fundamental material balance of critical mineral production, laying the groundwork for an industry liberated from fossil inputs and their legacy impacts.

Since founding, Travertine has raised over $29M in capital, including over $5M in US Federal and State government grants. We are an accomplished and driven team recognized by C&EN 10 startups to watch in 2022, Bloomberg NEF Pioneers in 2023, RMI Third Derivative 1st Gigaton Captured program in 2024, Mining Cleantech Challenge in 2026, and are a founding member of the Carbon Removal Alliance. Travertine designed, built, and successfully operated our core technology Demonstration Plant in Rochester, NY for over 3,000 hours, and delivered the project on-time and on-budget. We are now developing our first commercial plant, which will be the only new phosphate plant built on US soil in over 50 years.
