Travertine is a technology company.
Travertine Technologies develops and commercializes an electrochemical process that transforms industrial waste into valuable resources while simultaneously capturing carbon dioxide. Their proprietary method reclaims critical materials like purified phosphoric acid, sulfuric acid, and cementitious products from mining and fertilizer byproducts, creating a circular economy for these essential elements. This innovative approach offers a sustainable alternative to traditional resource extraction and waste management.
Travertine was founded in 2022 by Laura Lammers, a former professor of geochemistry at the University of California, Berkeley, and environmental engineer Owen Cadwalader. Their insight stemmed from recognizing the environmental impact and resource inefficiency of legacy industrial processes, particularly in phosphate production. Lammers’ academic background in geochemistry provided the scientific foundation for developing a novel electrochemical solution to tackle both waste valorization and carbon removal, addressing a significant gap in sustainable industrial practices.
The company’s solutions primarily serve the fertilizer, concrete, battery, and critical minerals industries by providing sustainable inputs and enabling carbon removal. Travertine envisions a future where industrial processes are fundamentally circular, extracting maximum value from existing resources while permanently sequestering carbon. Their mission is to meet critical material demands without generating harmful waste, fostering a more resilient and environmentally responsible industrial ecosystem.

Travertine Technologies is a climate tech startup founded in 2022 and headquartered in Boulder, Colorado, that develops circular chemical processes to convert mining and fertilizer production waste into valuable products like purified phosphoric acid and cement materials, while permanently removing carbon dioxide.[3][2][1] The company serves the mining, fertilizer, and cement industries by addressing waste generation—billions of tons annually from critical element extraction—producing zero-waste outputs, avoiding >98% gypsum landfill waste, utilizing 100% of ore concentrate (vs. industry ~50%), and mineralizing 0.75 tons of CO2 per ton of phosphoric acid.[2][1] With $11.5M in total funding, including an $8.5M round in June 2024, Travertine demonstrates strong growth momentum toward gigaton-scale carbon dioxide removal (CDR) integrated with industrial chemical production.[3][4]
Travertine was founded in 2022 to tackle the mining industry's core challenge: extracting vital elements for the energy transition without generating massive waste piles, drawing inspiration from Earth's natural chemistry.[5][3][1] The team's environmental problem-solvers emerged from this vision, focusing on circularity in phosphate processing—a legacy technology over a century old that leaves costly byproducts amid scarce land resources.[2][5] Early traction includes partnerships with global leaders in mining, cement, and fertilizer, plus rapid funding success: $11.5M raised across two rounds, with the latest $8.5M in 2024 to scale carbon-negative extraction for fertilizers, lithium, nickel, and lower-carbon cement.[3][2]
Travertine's edge lies in its electrified, circular technology that turns waste into profit and climate benefits:
Travertine rides the critical minerals boom for renewables—lithium, nickel, phosphates for batteries and fertilizers—amid surging demand from electrification and food security, while countering extractive industries' environmental toll.[1][2] Timing is ideal: legacy processes waste billions of tons yearly as land scarcity and byproduct costs rise, aligning with global net-zero mandates and CDR market growth projected to gigatons.[4][3] Market tailwinds include policy incentives for carbon removal, battery supply chain localization, and circular economy shifts, positioning Travertine to decarbonize foundational industries that enable the energy transition.[1][2]
Travertine is primed to scale its pilot partnerships into commercial plants, targeting gigaton CDR by co-producing chemicals for batteries and agriculture amid exploding critical mineral needs.[4][2] Trends like electrified processing, LFP battery dominance, and waste-to-value mandates will accelerate adoption, potentially evolving Travertine into a cornerstone supplier for sustainable mining.[3][1] As waste-to-upside tech matures, expect expanded influence in reshaping extractive industries for a circular, low-carbon future—turning today's mining headaches into tomorrow's climate wins.
