Abstract: What is described is an integrated steel mill and a bioreactor configured to produce useful products from the waste stream of the steel mill. A waste gas stack which is connected to the steel mill is connected to a heat exchanger to cool the waste gas from the steel mill. The cooled gas is pressurized using a pressurization apparatus connected to the heat exchanger. The pressurized gas is sent to an oxygen removal apparatus connected to the pressurization apparatus. An oxygen depleted waste stream from the oxygen removal apparatus is passed to a bioreactor (connected to the oxygen removal apparatus) where microorganisms ferment the waste stream to products. Optional apparatus such as scrubbers, valves, buffers, are also disclosed. The products of the fermentation in the bioreactor can be ethanol and or acetate.

Abstract: The invention relates to a steel mill adapted to provide gas stream(s) comprising CO to a microbial fermentation, the steel mill comprising a steel mill structure containing apparatus for a steel manufacturing process wherein said apparatus produces waste gases during various stages of the steel making process, said waste gases being directed into the atmosphere by a waste stack, wherein the waste stack is connected to a fermentation system by a transfer means connected to the waste stack to divert at least a portion of the waste gases to the microbial fermentation system.

Abstract: The invention relates to a method for producing products by microbial fermentation. The method comprises first converting a feed stream containing methane to a gaseous substrate comprising CO, of the invention include converting CO H2, and CO2 using a steam reforming zone and a water gas shift zone. The gaseous substrate is then converted to products such as alcohols and/or acids by to one or more products including alcohols and/or acids by fermentation using a carboxydotrophic microorganism.

Abstract: Methods of capturing carbon by microbial fermentation of a gaseous substrate comprising CO. The methods 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, also disclosed are to processes for producing alcohols, particularly ethanol, from industrial waste streams, particularly steel mill off-gas.
