Abstract
This invention relates to a series of treatments, both physical and chemical, to plant biomass resulting in the production of ethanol, lignin, and a high protein animal feed supplement. In plants having a high silica content, a fourth product is obtained, silica/caustic oxide (silicates solution, waterglass.) Both the 5-Carbon and 6-Carbon sugars are fermented to ethanol using an existing closed-loop fermentation system employing a genetically engineered thermophilic bacteria developed by Agrol, Ltd. The lignin and absolute ethanol are mixed producing a high energy fuel.
