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.”

The student-led Rice Wind Energy team clinched second place overall at the U.S. Department of Energy’s 2025 Collegiate Wind Competition (CWC), which challenges students nationwide to design and build wind turbines, develop wind energy projects and engage in public outreach to promote renewable energy.

“The Collegiate Wind Competition is such an incredible opportunity for students passionate about sustainability to gain industry-applicable, hands-on experience in the renewable energy space,” senior and team vice president Jason Yang said in a news release.

The event was hosted by the National Renewable Energy Laboratories at the University of Colorado Boulder campus. Over 40 teams entered the competition, with just 12 advancing to the final stage. The competition comprises four core contests: connection creation, turbine design, turbine testing and project development.

Rice Wind Energy had the largest team with 26 students advancing to the final stage of the competition. It picked up a first-place win in the connection creation contest, and also placed third in the project development, fourth in turbine testing and fifth in turbine design contests.

“This accomplishment is a testament to our focus, teamwork and unwavering determination,” senior Esther Fahel, Rice Wind Energy’s 2024-25 president, said in a news release. “It’s a remarkable experience to have watched this team progress from its inception to the competition podium. The passion and drive of Rice students is so palpable.”

In the Connection Creation contest, the team hosted a wind energy panel with Texas Tech University, invited local high school students to campus for educational activities, produced a series of Instagram reels to address wind energy misconceptions and launched its first website.

The team also developed an autonomous wind turbine and floating foundation design that successfully produced over 20 watts of power in the wind tunnel. They were also one of just a few teams to complete the rigorous safety test, which brought their turbine to below 10 percent of its operational speed within 10 seconds of pressing an emergency stop button. It also designed a 450-megawatt floating wind farm located 38 kilometers off the coast of Oregon by using a multi-decision criteria matrix to select the optimal site, and conducted technical modeling.

“I am amazed at the team’s growth in impact and collaboration over the past year,” senior Ava Garrelts, the team’s Connection Creation lead for 2024-25, said in a news release. “It has been incredible to see our members develop their confidence by building tangible skills and lifelong connections. We are all honored to receive recognition for our work, but the entire experience has been just as rewarding.”

Rice faculty and industry sponsors included David Trevas and faculty advisers Gary Woods and Jose Moreto, Knape Associates, Hartzell Air Movement, NextEra Analytics, RWE Clean Energy, H&H Business Development and GE Vernova, Rice’s Oshman Engineering Design Kitchen, George R. Brown School of Engineering and Computing, Rice Engineering Alumni and Rice Center for Engineering Leadership.

The BYU Wind Energy Team took home the overall first-place prize. A team from the University of Texas at Dallas was the only other Texas-based team to make the 12-team finals.
