Houston’s Gaurab Chakrabarti and Sean Hunt, the founders of the transformative chemical manufacturing company Solugen, have been named EY’s US National Award winners for Entrepreneur of the Year.

Solugen, also recently named a finalist in the 2023 Houston Innovation Awards, is an environmentally friendly approach that relies on smaller chemical refineries that helps in reducing costs and transportation-related emissions.

Some of their noted accomplishments includes innovations like the proprietary reactor, dubbed the Bioforge, which is a carbon-negative molecule factory and manufacturing process produces zero wastewater or emissions compared with traditional petrochemical refineries.The Bioforge uses a chemienzymatic process in converting plant-sourced substances into essential materials that can be used instead of fossil fuels.

Chakrabarti and Hunt were originally named regional winners in this year's competition this summer along with nine other Houston entrepreneurs.

Founded in 2016 by Hunt and Gaurab Chakrabarti, Solugen has raised over $600 million from investors like Sasol that believe in the technology's potential. The company is valued at reportedly over $2 billion. Solugen is headquartered in Houston, not because it is the hometown of Chakrabarti, but for what Houston brings to the company.

“There’s no way our business could succeed in the Bay Area," Chakrabarti said in a 2023 interview at SXSW where he detailed the offers Hunt and he received to move the business out of state. “For our business, if you look at the density of chemical engineers, the density of our potential customers, and the density of people who know how to do enzyme engineering, Houston happened to be that perfect trifecta for us.”

Even though they are headquartered in Houston, Solugen recently secured plans to expand to the Midwest, as in November they announced its newest strategic partnership with sustainable solutions company ADM (NYSE:ADM) in Marshall, Minnesota. The partnership includes plans for Solugen to build a 500,000-square-foot biomanufacturing facility next to an existing ADM facility , with the two companies working together on producing biomaterials to replace fossil fuel products.

“The strategic partnership with ADM will allow Solugen to bring our chemienzymatic process to a commercial scale and meet existing customer demand for our high-performance, cost-competitive, sustainable products,” Chakrabarti said in a news release. “As one of the few scaled-up and de-risked biomanufacturing assets in the country, Solugen’s Bioforge platform is helping bolster domestic capabilities and supply chains that are critical in ensuring the U.S. reaches its ambitious climate targets.”

For Chakrabarti and Hunt, Solugen was born out of a 12-year friendship, and the journey began after a friendly card game. After an entrepreneurship contest at MIT, which earned them second place and a $10,000 prize, they invested the winnings to work on what would become Solugen, a proof-of-concept reactor with materials bought from a local home improvement store.

"We had a conviction that we were building something that could be impactful to the rest of the world,” Chakrabarti said at SXSW in 2023.

Houston-based sustainable chemicals co. to build ​Midwest biomanufacturing facility

it's corn

Solugen has scored a partnership with a global company to build a biomanufacturing facility adjacent to an existing corn complex in Marshall, Minnesota.

Solugen, a Houston company that's designed a process that converts plant-derived substances into essential materials, has announced its newest strategic partnership with sustainable solutions company ADM (NYSE:ADM). The partnership includes plans for Solugen to build a 500,000-square-foot biomanufacturing facility next to an existing ADM facility in the Midwest. The two companies will collaborate on producing biomaterials to replace fossil fuel-based products.

“The strategic partnership with ADM will allow Solugen to bring our chemienzymatic process to a commercial scale and meet existing customer demand for our high-performance, cost-competitive, sustainable products,” Gaurab Chakrabarti, co-founder and CEO of Solugen, says in a news release. “As one of the few scaled-up and de-risked biomanufacturing assets in the country, Solugen’s Bioforge platform is helping bolster domestic capabilities and supply chains that are critical in ensuring the U.S. reaches its ambitious climate targets.”

The company plans to begin on-site construction early next year, with plans to startup in the first half of 2025. The project should create at least 40 permanent jobs and 100 temporary construction positions.

“Sustainability is one of the enduring global trends powering ADM’s growth and underpinning the strategic evolution of our Carbohydrate Solutions business,” Chris Cuddy, president of ADM’s Carbohydrate Solutions business, says in the release. “ADM is one of the largest dextrose producers in the world, and this strategic partnership will allow us to further diversify our product stream as we continue to support plant-based solutions spanning sustainable packaging, pharma, plant health, construction, fermentation, and home and personal care.”

Founded in 2016 by Chakrabarti and Sean Hunt, Solugen's carbon-negative molecule factory, named the Bioforge, uses its chemienzymatic process in converting plant-sourced substances into essential materials that can be used instead of fossil fuels. The manufacturing process is carbon neutral, and Solugen has raised over $600 million from investors that believe in the technology's potential.

“The initial phase of the project will significantly increase Solugen’s manufacturing capacity, which is critical for commercializing our existing line of molecules and kicks off plans for a multi-phase large-scale U.S. Bioforge buildout,” Hunt, CTO of Solugen, says in the release. “The increase in capacity will also free up our Houston operation for research and development efforts into additional molecules and market applications.”

The project should create at least 40 permanent jobs and 100 temporary construction positions.

"As a community with a strong foundation of agriculture and innovation, we look forward to welcoming Solugen to Marshall. This industry-leading facility will serve as a powerful economic driver for the city, creating new jobs and diversifying our industry,” City of Marshall Mayor Bob Byrnes says in the statement. "We are thankful for ADM’s longstanding commitment and impact to Marshall, which has paved the way for this remarkable partnership and continues to further economic growth to our region."

It's the second major company partnership announcement Solugen has made this month, with a new arrangement with Sasol being secured last week.

Houston startup secures $5M to turn oilfield wastewater into critical minerals

fresh funding

Houston-based startup Altillion has secured $5 million in seed funding to accelerate the commercialization of its proprietary IRIS and ALIX technologies, which convert oilfield-produced water into valuable minerals.

San Francisco-based EIC Rose Rock and Houston-based Flathead Forge led the round. Altillion says the funding will go toward pilot facilities and commercial deployments as the company looks to scale in the U.S.

“Altillion’s efficient and scalable technologies are needed more than ever to reshape critical mineral recovery and facilitate beneficial use of oilfield brines,” Jay Keener, Altillion’s CEO and co-founder, said in a news release. “We’re uniquely positioned to provide a stable, domestic supply of the critical minerals needed for electronics, batteries, healthcare and national defense technologies. This investment from EIC Rose Rock and Flathead Forge enables us to strategically accelerate this impact and is very timely given the current geopolitical dynamics.”

Altillion's IRIS and ALIX platforms extract minerals like iodine, lithium and copper from oilfield-produced water, geothermal brines and salars. This process allows companies to unlock new sources of revenue while also boosting the domestic critical minerals supply chain. The company announced earlier this summer that it will launch a feasibility project in the Permian Basin and aims to develop a path to commercial-scale implementation in the field.

“We are excited to partner with Altillion to scale and deploy these world-class technologies to access the vast wealth hidden in wastewater,” David Clouse, Managing Director of EIC Rose Rock, added in the release. “With Altillion, we’re expanding our ability to empower the energy industry to domestically source the critical minerals America needs for a robust economy and supply chain.”

Altillion was founded by Keener and COO Scott Buckwald in 2023. Keener previously founded KDH Trading, where Buckwald also serves as COO, according to his LinkedIn page.

Houston's KBR to provide tech for Singapore SAF plant

SAF agreement

Houston engineering and technology contractor KBR has been picked as the technology provider for what’s expected to be Asia's first commercial-scale ethanol-to-jet sustainable aviation fuel (SAF) plant.

The proposed plant on Jurong Island in Singapore is being developed by Keppel Ltd.’s Infrastructure Division and Aster Chemicals and Energy. KBR will provide technology licensing and Front-End Engineering Design (FEED) services based on its PureSAF technology.

The plant has a planned production capacity of up to 100,000 tons of SAF per year. The plant is subject to final investment decisions and regulatory approvals.

“We are looking forward to working with Keppel and Aster on this key project and to support Singapore’s ambition of becoming Asia’s leading SAF hub and advancing the ongoing efforts to decarbonize the country’s aviation ecosystem,” Stuart Bradie, KBR president and CEO, said in a news release.

According to KBR, its PureSAF Technology can process multiple feedstocks like bioethanol, syngas, carbon dioxide and hydrogen and convert them to SAF, diesel and gasoline.

The technology was developed by Swedish Biofuels AB and commercialized by KBR.

“KBR’s PureSAF is a feedstock-flexible, bankable technology that is designed to deliver a 100% drop in jet fuel, ready to power aircraft without blending,” Bradie added in the news release. “We are constantly innovating our SAF solution to make it compatible with feedstock availability in different regions and to enable the aviation industry to transition to low-carbon jet fuel with a cost-optimized approach.

KBR has also entered into a memorandum of intent with Keppel’s Infrastructure Division, which states that the companies will collaborate again on decarbonization efforts across biofuels, plastic recycling, digitalization via AI, and SAF.

KBR announced in October that it would spin off its Mission Technology Solutions business, nicknamed SpinCo. The scaled-down KBR, nicknamed RemainCo, would concentrate solely on sustainability technology and services designed to reduce carbon emissions and support energy transition efforts. SpinCo named its new CEO and CFO earlier this month.
