Abstract: The present invention relates to an energy-efficient process for the treatment of plant biomass, particularly sugar cane, for the production of carbohydrates and ethanol, using physico-chemical and extraction techniques, as well as very simple milling configurations, thereby minimizing energy consumption during extraction of the cane juice. The biomass treated and obtained through this process, when subjected to a fermentation process for the production of ethanol, increases the yield of the process in comparison with that of traditional sugar cane. It can also be used for the production of enzymes, animal feedstuffs, and other useful products.

Abstract: A system and a process for the production of ethanol and related products from lignocellulosic biomasses (second generation—2G-ethanol), particularly from sugarcane bagasse and straw is provided, however not limited thereto, integrated with conventional processes for the production of ethanol (first generation—1G-ethanol) such as, for example, from sugarcane juice and/or molasses (either in sugar and ethanol plants or in autonomous distilleries), corn, grain, wheat, sugary sorghum, white beetroot, among others, including the recovery/reuse of streams and effluents. More specifically, an integrated process for the production of ethanol and related products where the process warrants increased efficiency particularly in the use of the raw material, steam, electric power and treated water is provided.

Abstract: The use of stillage in a saccharification/fermentation process of lignocellulosic biomasses, regardless of the form of the biomasses and regardless of the use of the obtained final hydrolyzed broth. The beneficial effect conferred by the stillage to the saccharification process of lignocellulosic biomasses presents among other characteristics the ability to buffer the reaction medium, especially when such process takes place in an enzymatic route, but not limited to it, regardless of the type of biomass being used and the type of pretreatment to which the biomass is subjected. Fermentation processes, such as the ethanol production, using stillage as source of nutrients such as, for example, nitrogen, for growing microorganisms, but not limited to it.
