ImpactAlpha, June 15 — Travertine’s Laura Lammers founded the company to respond to the twin challenges of atmospheric carbon and sulfate waste.
“By mimicking and enhancing earth’s natural weathering process, we can solve both these problems at a massive scale in partnership with mining and fertilizer companies,” Lammers told ImpactAlpha.
The Boulder, Colo.-based company has raised $3 million for an electrochemical process that captures and sequesters carbon and recycles sulfate to extract critical elements and produce sulfuric acid for fertilizer.
Grantham Environmental Trust and Clean Energy Ventures co-led Travertine’s seed financing.
“Every aspect of our process we think of as being inherently scalable, and has already been tested at large scale,” Lammers said. “We’re making novel combinations of tested processes so that we can commercialize within a short period of time.”
