Travertine Technologies, Inc. has announced the closing of an $8.5 million financing round to commercialise its novel electrochemical platform that enables carbon-negative production of fertilizer and critical elements like lithium and nickel while eliminating chemical waste.
Travertine’s technology upcycles industrial sulfate waste and CO2 captured directly from the air into sulfuric acid and carbonate advanced cement components that permanently sequester CO2. Sulfuric acid, the leading industrial chemical, is used to extract phosphorus, lithium, nickel, and other critical elements from ores. By eliminating sulfate wastes produced by conventional extractive processes, the technology addresses a longstanding environmental challenge in the fertiliser and mining industries.
