Houston-born startup Cemvita says it has completed a 75,000-liter industrial fermentation run of its FermOil product, a renewable natural oil designed to serve as a drop-in feedstock for sustainable aviation fuel. The industrial-scale demonstration took place at a pilot facility in Ghent, Belgium, used industrial crude glycerin as input, and reached the technical benchmarks the company set for commercial scale-up.
In a press release via Bio Base Europe Pilot Plant, Cemvita said the campaign validated the scalability of its FermWorks industrial biomanufacturing platform and met its target metrics for FermOil production. CEO Moji Karimi called the outcome “not just a fermentation milestone” and argued it shows how existing biodiesel infrastructure can be repurposed into assets for a circular bioeconomy.
Feedstock and regulatory value
Cemvita describes FermOil as a renewable natural oil made from industrial crude glycerin, a low-value byproduct of biodiesel production, and positions it as compatible with existing HEFA and co-processing refineries, according to Cemvita. That compatibility matters for potential demand, since the European Union’s Renewable Energy Directive (RED III) and its Annex IX rules determine which feedstocks qualify as advanced biofuels. Annex IX classifications are a key policy backdrop for sustainable aviation fuel markets as outlined on EUR-Lex.
Why the scale-up matters
The company says it took FermOil from bench work through 2-liter, 30-liter, 1,500-liter and 15,000-liter stages before reaching 75,000 liters, showing reproducible performance across roughly a 2,500-times increase in volume. That kind of consistency is the hurdle that often trips up lab concepts on their way to industrial gear.
“Across multiple vessel runs, the fermentation control strategy remained stable, and the results were consistent all the way from 30 liters to 75,000 liters,” Cemvita’s VP of Engineering Luciano Zamberlan said in the announcement via Bio Base Europe Pilot Plant.
Commercial push and partners
Cemvita says it is now advancing commercial deployment talks with partners in Brazil, the European Union and the United Kingdom, and has been lining up local collaborators to test waste streams and assemble supply chains. A recent MOU with Sumitomo Corporation do Brasil highlights the Brazil strategy, per PR Newswire, while earlier research partnerships with Brazilian group REMA were announced via Business Wire.
What it means for Houston
The milestone lands as another data point that Houston’s energy and biotech sectors are converging around industrial decarbonization tools rather than consumer apps. Local coverage notes Cemvita’s Houston base and its international push into Brazil and Europe, showing that the city’s startups are exporting decarbonization technology abroad, as reported by InnovationMap.
Cemvita says the demonstration de-risks commercial scale-up and opens the door for FermWorks integrations that could let biodiesel plants convert crude glycerin into renewable oils for sustainable aviation fuel and other markets, according to Cemvita. The company now shifts into partner negotiations and commercial planning as it works to turn the technical proof point into operating facilities and actual product on the market.
