First-generation grain ethanol biofuel has affected the historical excess capacity problem in U.S. agriculture. Second …-generation cellulosic ethanol biofuel has had difficulty achieving cost-competitiveness. Third-generation drop-in biofuels are under … development. If lignocellulosic biomass from perennial grasses becomes the feedstock of choice for second- and third …

Acid hydrolysis of surplus cellulosic materials, such as bagasse, into fermentation sugars offers enormous opportunity …. Arkenol has developed and patented a strong acid hydrolysis process which can economically convert cellulose into ethanol for … transportation fuel.
