Houston-based Advantek Waste Management Services, which specializes in deep-injection wells that minimize the impact of land, air, and water waste, has launched a carbon removal and storage company.

The spinoff, Vaulted Deep, is getting off the ground with $8 million in seed funding.

Vaulted diverts sludgy organic waste, such as agricultural and livestock waste, before it’s dumped in a landfill or waterway or simply left on land to decompose. It then captures and stores carbon emissions generated by the organic waste.

A study published earlier this year by Louisiana State University ecologist Brian Snyder estimated that organic waste generates five gigatons of carbon dioxide per year. A gigaton equals one billion metric tons.

Vaulted is already off to an impressive start. For one thing, the startup has raised an $8 million seed round led by New York City-based carbon removal fund Lowercarbon Capital. Other investors include Advantek and San Francisco-based climatech VC fund Earthshot Ventures.

In addition, Vaulted has already nailed down purchase commitments from Frontier, a marketplace for buyers and sellers of carbon removal credits. Ryan Orbuch, a partner at Lowercarbon, is one of Frontier’s strategic advisers.

“Vaulted is literally cleaning up the planet, scaling field-proven injection terminology to safely dispose of harmful wastes like biosolids while permanently storing away millions of tons of CO2,” Orbuch says in a Vaulted news release.

While injection sequestration sites often take years to gain permits and start operating, Vaulted already boasts two permitted sites that are up and running. Vaulted offers carbon removal for $300 per ton, compared with more than $500 per ton charged by some competitors.

Advantek founder Omar Abou-Sayed is switching from CEO to chairman of Advantek, which launched in 1999, and will serve as executive chairman of Vaulted. Julia Reichelstein, a former investor at San Francisco-based climatech VC fund Piva Capital, has been tapped as CEO of Vaulted.

“Unlike many carbon removal technologies still in R&D, Vaulted’s technology and sites can safely and permanently store carbon underground, at scale, today,” says Abou-Sayed. “The early removals we will deliver are pivotal to keeping the window open to hold our planet’s warming below 1.5 degrees Celsius.”
