Occidental's venture arm — Oxy Low Carbon Ventures — has announced its plans to construct and operate a one metric ton per month bio-ethylene pilot plant featuring Houston-based Cemvita Factory's technology that biomimics photosynthesis to convert carbon dioxide into feedstocks.

The new plant will scale the process, which was jointly developed between Cemvita and OLCV, and is expected sometime next year, according to a press release from Oxy.

"Today bio-ethylene is made from bio-ethanol, which is made from sugarcane, which in turn was created by photosynthesizing CO2. Our bio-synthetic process simply requires CO2, water and light to produce bio-ethylene, and that's why it saves a lot of cost and carbon emissions," says Moji Karimi, co-founder and CEO of Cemvita Factory, in the release. "This project is a great example of how Cemvita is applying industrial-strength synthetic biology to help our clients lower their carbon footprint while creating new revenue streams."

Oxy and Cemvita have been working together for a while, and in 2019, OLCV invested an undisclosed amount into the startup. The investment, according to the release, was made to jointly explore how these advances in synthetic biology can be used for sustainability efforts in the bio-manufacturing of OxyChem's products.

"This technology could provide an opportunity to offer a new, non-hydrocarbon-sourced ethylene product to the market, reducing carbon emissions, and in the future benefit our affiliate, OxyChem, which is a large producer and consumer of ethylene in its chlorovinyls business," says Robert Zeller, vice president of technology at OLCV, in a news release.

Moji Karimi founded the company with his sister and Cemvita CTO, Tara, in 2017. The idea was to biomimic photosynthesis to take CO2 and turn it into something else. The first iteration of the technology turned CO2 into sugar — the classic photosynthesis process. Karimi says the idea was to create this process for space, so that astronauts can turn the CO2 they breathe out into a calorie source.

"Nature provided the inspiration," noted Dr. Tara Karimi, co-founder and CTO of Cemvita Factory. "We took a gene from a banana and genetically engineered it into our CO2-utilizing host microorganism. We are now significantly increasing its productivity with the goal to achieve commercial metrics that we have defined alongside OLCV."

A couple weeks ago, Moji Karimi joined the Houston Innovators Podcast to discuss growth and challenges Cemvita Factory faced.

"We're defining this new category for application of synthetic biology in heavy industries for decarbonization," he shares on the show. Stream the episode below.

Growing Houston biotech startup is capturing a new way for oil and gas to get to carbon negative

HOUSTON INNOVATORS PODCAST EPISODE 76

As more and more energy companies are focusing on reducing their carbon footprint ahead of lofty clean energy goals, Moji Karimi, CEO and co-founder of Houston-based Cemvita Factory, is doing his oil and gas clients one better. In addition to reducing carbon emissions, Cemvita provides an additional revenue stream for its clients.

Karimi founded the company with his sister and Cemvita CTO, Tara, in 2017. The idea was to biomimic photosynthesis to take CO2 and turn it into something else. The first iteration of the technology turned CO2 into sugar — the classic photosynthesis process. Karimi says the idea was to create this process for space, so that astronauts can turn the CO2 they breathe out into a calorie source.

"While we were doing that, we realized the big picture is not just the space application. If we could apply the same technology for other chemicals made in energy-intensive way, then we could actually help with climate change," Karimi says on the podcast.

Now, Cemvita has 30 different molecules its technology can produce and works with the likes of BHP, Oxy, and more energy clients to take their carbon emissions and turn it into something useful.

"It's not just for sustainability reasons — it's part of the reinvention of the company to maintain its legacy for the next few decades to come," Karimi adds.

While 2020 was a chance for Cemvita to reset, by Q4 of last year the company was in growth mode and got back to the lab. The company's teams were divided between two spots — one being an R&D team in larger office at JLABS @ TMC — and Karimi says later this year that will change. Cemvita is moving into a larger, combined space in Upper Kirby in May.

But Karimi says one of the biggest challenges Cemvita is facing is that its doing something that's never been done before. There's a huge learning curve for clients and oil and gas stakeholders.

"There weren't biotech companies working with oil and gas companies for this use case that we have now," Karimi says. "We're defining this new category for application of synthetic biology in heavy industries for decarbonization."

There are other companies in the carbon capture and neutralization fields, though they are taking slightly different approaches. Rather than being competitive, companies in this space are working together for a greater good.

"The more successful that some of these other companies are in opening up the market, that also helps us the same way we're doing for them," Karimi says. "It's an interesting and collaborative area, because at the end of the day, the outcome is good for the world."

Karimi shares more about what Cemvita's growth plans on the episode. Listen to the full interview below — or wherever you stream your podcasts — and subscribe for weekly episodes.
