Cemvita opens CO₂-to-chemicals pilot

Volume 101, Issue 13
The start-up Cemvita has begun production at its 55,000 L pilot plant in Houston, which makes fatty acids from CO2 via fermentation. In contrast to most CO2-to-chemicals projects being developed, the company’s eCO2 Oil process does not use hydrogen, electricity, or sunlight as an energy source. Instead, the firm employs mixed organic waste as an electron donor for CO2 reduction carried out by custom microbial consortia. Chief operating officer Charles Nelson says the plant’s product is chemically similar to palm, soybean, or canola oil.
