During the last few decades, sugar has emerged as the main feedstock for production of biofuels and chemicals. The cost and availability of these fuels/chemicals vastly depends on the source of the sugar. Currently most of the processes are based on sugar from corn, cane, and beets; however the use of such food-derived raw materials is not sustainable. Although lignocellulosic sugar is sustainable, historically there has not been economically viable process to refine it when compared to other food-based feedstocks. The new Organosolv process, which also produces pure lignin and organic solvents, has proven to be a potential pathway for an economically competitive lignocellulosic sugar production. Based on AST analysis, application of pure lignin as polymer was one path to the economical viability of the Organosolv process. During the first half of 2013, AST successfully used Organosolv based lignin up to 50% as additive to polymers and produce samples for test and evaluations
