HOUSTON (ICIS)--Cobalt Technologies has scaled up its production process for bio-based n-butanol (NBA), the US developer of bio-based chemicals said on Tuesday.

Cobalt said that in a recent production run it achieved a fermentation scale of more than 100,000 litres, compared with a pilot scale of 4,000 litres.

"This most recent production run demonstrates commercial-scale metrics for Cobalt's biobutanol fermentation technology," said Bob Mayer, CEO of Cobalt Technologies.

The production run was carried out with minimal modification to the existing aerobic system, “highlighting the flexibility of Cobalt's anaerobic technology and showing the robustness of Cobalt's biocatalyst”, the company said.  

The demonstration also provided validation of Cobalt's ability to take advantage of opportunities to retrofit or co-locate with existing ethanol plants, whether based on sugarcane or corn, for the production of butanol, it added. 

Earlier this week, Cobalt announced a partnership with two Asian chemical companies for the development of a biomass-to-butadiene (BD) solution.
