Abstract
The invention relates to methods of capturing carbon by microbial fermentation of a gaseous substrate comprising CO. The methods of the invention include converting CO to one or more products including alcohols and/or acids and optionally capturing CO2 to improve overall carbon capture. In certain aspects, the invention relates to processes for producing alcohols, particularly ethanol, from industrial waste streams, particularly steel mill off-gas.
Claims9
A method of producing one or more products by microbial fermentation of a steel manufacturing process waste gas stream, the method comprising:
- i. receiving off or waste gas stream(s) comprising CO from a steel manufacturing process;
- ii. passing the gas stream(s) to a bioreactor containing a culture of one or more microorganisms;
- and
- iii. fermenting the culture in the bioreactor to produce one or more fermentation products, said fermentation products including alcohols and/or acids.
