Phosphorus for the 21st century

Legacy phosphate technology was developed more than a century ago. Today, land and resources are scarce and byproduct management is costly. Travertine’s next-generation phosphate technology is circular, carbon-negative, and extracts more value from the same ore. We are here to meet the vital material needs of today while helping preserve a brighter tomorrow.

Travertine’s breakthrough technology produces phosphoric acid and cement materials instead of byproducts that are landfilled.

Closing the Loop between fertilizer and cement Industries

Grid Storage and agriculture field

PURIFIED PHOSPHORIC ACID for food and batteries

One product, many uses. Phosphoric acid is a critical component of fertilizer. The specialized product, purified phosphoric acid is used in the food & beverage industry, water treatment, and increasingly in LFP (lithium-iron-phosphate) batteries for vehicles and the grid.

Building partnerships

Conventional Process
Travertine Process
The Travertine Process reduces waste and connects the phosphate and cement industries. Unlike the conventional method, the Travertine Process does not produce gypsum waste, and instead produces solid cementitious materials that can make low-carbon cement.

Travertine technology by the numbers

  • Gypsum waste avoided

    >98%

    Conversion efficiency gypsum to calcium carbonate

  • Ore concentrate utilized

    100%

    VS ~50% PHOSPHATE industry standard

  • Carbon dioxide mineralized

    0.75 T

    Per Ton of Phosphoric Acid

Avoid landfill, remove carbon dioxide, extract more value, lower cost.

ELECTRIFIED CHEMICAL INDUSTRY

Travertine was built to extract more value from ore while solving massive environmental challenges. We are scaling in partnership with the world’s largest industries: mining, cement, fertilizer.
