Coskata says its proprietary process, which relies on a combination of gasification and fermentation by microorganisms, is up to six times more efficient than the production of ethanol from corn. The process can handle everything from switchgrass to industrial waste to household garbage, produces fewer emissions and noxious byproducts than comparable systems, and will result in ethanol with a production cost of around one dollar per gallon.
