Coskata is commercializing a proprietary process and related technologies for the conversion of a wide variety of input materials into ethanol. Coskata has an efficient, affordable, and flexible three-step conversion process:

1. Incoming material converted to synthesis gas (gasification)
2. Fermentation of synthesis gas into ethanol (bio-fermentation)
3. Separation and recovery of ethanol (separations)

Ethanol can be manufactured using this cutting edge technology to provide environmental, economic, and national security benefits.

During gasification, carbon-based input materials are converted into syngas using well-established gasification technologies. After the chemical bonds are broken using gasification, Coskata's proprietary microorganisms convert the resulting syngas into ethanol by consuming the carbon monoxide (CO) and hydrogen (H2) in the gas stream. Once the gas-to-liquid conversion process has occurred, the resulting ethanol is recovered from the solution using well proven distillation methods.

Coskata's proprietary microorganisms eliminate the need for costly enzymatic pretreatments, and the bio-fermentation occurs at low pressures and temperatures, reducing operational costs. In addition, the Coskata process has the potential to yield over 100 gallons of ethanol per ton of dry carbonaceous input material, reducing both operational and capital costs. Coskata's exclusively licensed separation technology has the potential to dramatically improve the separations and recovery component of ethanol production.
