CARY – Sustaera, Inc., a Cary-based startup that according to its website has developed what it calls “a novel Direct Air Capture technology which uses renewable energy that will allow us to remove, replace, and reuse carbon,” has raised nearly $5 million in capital from two investors, according to an SEC filing.

The company calls its technology “the missing link to restore the Earth’s carbon balance” on its website.

“Our carbon-negative, cost-effective, and modular direct air capture system works around the clock in locations ranging from open grasslands to arid deserts to tropical savannas, serving as the cornerstone of a rapidly expanding carbon ecosystem that will include capture, credits, sequestration, and utilization,” the website reads.

The company is a partner of Susteon, as noted on the company’s website.  Both companies share an address in Cary, according to their websites.  Susteon received a grant in February of 2021, worth nearly $75,000, “to develop a direct air capture (DAC) technology for capturing and converting carbon dioxide directly from large emitting sources.”

Sustaera CEO Shantanu Agarwal signed the SEC filing, and declined to comment to WRAL TechWire regarding the funding.
