TRAVERTINE: UPCYCLING WASTE AND CAPTURING CO₂
The challenge
The main challenges Travertine addresses is the upcycling of industrial waste streams and the capture and mineralization of CO₂ emissions from industrial sources and the atmosphere.
The solution
The Travertine process creates a fossil-free source of sulfuric acid that helps minimize waste from mining and fertilizer while enabling the critical element extraction needed for the energy transition.
Travertine’s approach utilises carbon mineralization to transform captured CO₂ into stable minerals, mimicking natural processes in a controlled and scalable process. With the potential to produce valuable materials for construction – like inputs for greener cement – while embodying circular principles, the Travertine Process has the potential to be applied across multiple industries globally.

“Travertine addresses several key challenges of the global energy transition at once. It uses renewable energy while dealing with intermittency, via an electrochemical process; it drives circularity by upcycling industrial waste into valuable products for the fertilizer and cement industries; and it reduces carbon emissions by capturing and mineralizing CO2 from the atmosphere.”
Dr. Laura Lammers
Founder and CEO of Travertine
“The global energy transition is driving huge demand growth for critical elements such as lithium, copper, and phosphorus, as well as the sulfuric acid needed to extract and refine them.”
“Travertine maximises value and brings circularity to these processes. Partnering with major industrial leaders like Holcim is critical to building a new decarbonized economy at scale.”
