Houston-based cleantech startup Cemvita Factory is embarking on a potentially game-changing pilot project in Arizona.

Cemvita has sealed a deal with Australia-based Arizona Lithium, a lithium mining company, to test the startup’s technology for extraction of lithium from clay and sedimentary materials. The project is being carried out at Arizona Lithium’s new Lithium Research Center in Tempe, Arizona, which is set to start operating early next year.

“We are excited to see the results of the partnership start to show in the next three to six months, at which time we will assess further partnership potential,” says Paul Lloyd, managing director of Arizona Lithium.

Cemvita, whose technology aims to reduce carbon emissions, says the new partnership will help develop more environmentally friendly ways of mining lithium for products such as electric car batteries.

As the startup explains, lithium is an important metal in the energy transition movement, but most commercial lithium extraction is done at salt-flat brines through a process of evaporation and chemical recovery or from lithium-bearing ores through a process that involves crushing, roasting, and acid leaching. However, these processes consume a lot of energy and damage the environment.

“This pilot work in Arizona is a great step forward in our drive to both reduce the footprint of mining and unlock the mineral resources that are crucial for our planet’s renewable energy future,” Marny Reakes, Cemvita’s vice president of mining biotech, says in a news release.

Cemvita says its team will rely on biomining from sedimentary resources, reducing carbon emissions and decreasing the generation of mining waste.

“Our goal,” says Charles Nelson, chief business officer of Cemvita, in the release, “is to enable the most environmentally friendly end to end process of mining lithium through the application of our technology. This includes utilizing cleaner methods of extraction with the option of layering Cemvita’s other beneficial technologies such as CO2 based fuels and decarbonizing processing in the mining space.”

Brother-and-sister team Moji and Tara Karimi founded the startup in 2017. Investors include Oxy Low Carbon Ventures, an investment arm of Houston-based Occidental Petroleum, as well as BHP Group, Mitsubishi, and United Airlines Ventures.

Cemvita’s technology enables the sustainable extraction of natural resources, carbon-negative production of chemicals and fuels, and regeneration of waste as feedstock.

Houston ranks among 15 U.S. hot spots for women in tech

Ranking It

Houston is soaring among the best places in the U.S. for women in tech, a new report says. Houston ranked No. 15 nationwide in SmartAsset's new report, "Best and Worst Cities for Women in Tech — 2026 Study," which compared the 50 biggest U.S. cities across four metrics:

  • Gender pay gap — women's median earnings as a percentage of men’s median earnings in tech
  • The share of all tech workers that are women
  • The overall concentration of employment for tech workers, defined as "tech workers as a share of the local workforce"
  • Women tech workers’ median earnings, adjusted for regional price parity
For the purpose of the study, tech workers are defined as "city residents employed in computer and mathematical occupations." The study's findings show that fewer than 9,500 tech workers in Houston are women, or 25.6 percent of the total tech workforce in the city. In total, tech workers in general make up less than 3 percent of the Houston workforce.Despite the high ranking, women tech workers in Houston have a sizeable gap to cross to receive equal pay compared to their male counterparts in the same industry. Women tech workers make just over $97,000 in median earnings after adjusting for regional price parity, which is only 93 percent of what male tech workers make, SmartAsset found.

There are only two U.S. cities where women in tech earn more than what their male counterparts: Miami and Memphis, Tennessee. Women tech workers in Miami make an adjusted $88,650 in median earnings, or 101.7 percent of what men in tech make. In Memphis, women make $84,718 in adjusted earnings, or 101.5 percent of what men in tech earn.

The findings also assert that women remain underrepresented in the nation's overall tech sector, despite making up nearly half of the total workforce. Only 22.6 percent of the country's tech labor force is made up of women, according to the Equal Employment Opportunity Commission."Opportunities for women in tech can vary considerably by location, and these differences shape access to jobs, career advancement and earning potential," the report's author wrote. "In some places, women account for a larger share of tech workers, face narrower pay gaps and enjoy a stronger local labor market. In others, they may encounter a more challenging career environmentThe six other Texas cities that earned spots in the report are Austin (No. 6), Fort Worth (No. 26), Dallas (No. 32), Arlington (No. 38), San Antonio (No. 42), and El Paso (No. 49).

The top 10 best U.S. cities for women in tech are:

  • No. 1 – San Jose, California
  • No. 2 – Seattle, Washington
  • No. 3 – San Francisco, California
  • No. 4 – Atlanta, Georgia
  • No. 5 – Baltimore, Maryland
  • No. 6 – Austin, Texas
  • No. 7 – Oakland, California
  • No. 8 – Portland, Oregon
  • No. 9 – Boston, Massachusetts
  • No. 10 – Minneapolis, Minnesota
