Critical elements such as phosphorus and lithium help drive decarbonization and feed the world. We partner with the mining and fertilizer industries to produce metals, chemicals, and building materials with zero waste and zero carbon.
THE TRAVERTINE
PROCESS
ONE PROCESS, MULTIPLE BENEFITS
ELIMINATE WASTE
Mining and fertilizer production produce billions of tons of gypsum waste. Our process eliminates this waste and instead produces material to blend into cements.
INDUSTRIAL ACID
Our process produces sulfuric acid or purified phosphoric acid without the waste products.
CARBON REMOVAL + SEQUESTRATION
Our process includes direct air capture (DAC) to remove CO2 from the air and permanently store it in building materials.
HOW IT WORKS
1. Electrolysis generates sulfuric acid and caustic solutions.
2. Direct Air Capture (DAC) uses caustic solution to pull carbon dioxide from the air.
3. Mineralization uses captured carbon dioxide to convert gypsum into carbon-negative building materials.
4. Phosphoric acid production uses sulfuric acid to digest rock phosphate and ultimately produce purified phosphoric acid.

OUR ORIGIN STORY
Travertine was founded by Laura Lammers, PhD, a former professor of geochemistry at the University of California, Berkeley and the Lawrence Berkeley National Lab, and leading expert in carbonate mineralization. Laura had been working on carbonates her entire career and wondered how we could clean up and decarbonize the materials we rely on for the energy transition. The Travertine Process was inspired by two key insights:
1. To utilize and sequester CO2 at the gigaton-scale, we need gigaton-scale products for the world’s largest industries, and
2. If we couple carbonate mineralization with critical element production, we can reduce cost while eliminating waste.

ACCOLADES
A new demo plant will repurpose mining waste and also capture CO2
Travertine’s demo facility in Rochester, NY, will upcycle captured CO2 and discarded gypsum into sulfuric acid for use in a nearby metals company’s operations.
Travertine makes sulfuric acid while sequestering carbon
Technology startup Travertine has developed a process to remove carbon dioxide (CO2) from the air and sequester it permanently, while also making sulfuric acid, reportedly the most used inorganic chemical in the world.
Mining independence is the key to energy independence
Travertine has a circular economy play: capture carbon by upcycling sulfuric acid from mine waste and then use that acid for the extraction of lithium, nickel and cobalt.
