Travertine

About

Travertine Technologies, Inc. is a climate tech company based in Boulder, Colorado, focused on carbon dioxide removal (CDR) and sustainable chemical production. Founded in 2022, the company has raised $13.52 million in funding, including an $8.5 million Series A round in June 2024, co-led by Holcim MAQER Ventures. The company utilizes a proprietary electrochemical process to convert sulfate-rich mining byproducts into carbon-negative sulfuric acid and green hydrogen, while sequestering CO₂ into carbonate minerals. Their products include carbon-negative sulfuric acid, carbonate minerals for construction materials, and green hydrogen, which supports clean energy applications. Travertine partners with industries such as mining, fertilizer production, construction, and clean energy to enhance sustainability and reduce waste. The company operates a demonstration plant in Boulder and aims to scale its CO₂ sequestration efforts at partner mine sites.
