About Travertine Technologies

Travertine Technologies is a climatetech company that has developed a process for carbon dioxide removal and critical element production from mining waste. The company's technology utilizes sulfate waste from mining operations to produce sulfuric acid, which is then used to extract valuable metals from mine tailings. This process also permanently sequesters carbon dioxide through mineral carbonation.

Travertine is focused on scaling its technology for commercial use in the mining, fertilizer, and cement production industries. By creating a circular process that transforms waste into valuable products, the company aims to address environmental challenges in these sectors while also contributing to climate change mitigation. Travertine is currently building a demonstration plant to showcase the effectiveness of its technology and has secured funding to support its growth and development.
