Abstract: The current invention concerns methods and products related to the production of alcohol from sugar cane and/or sweet sorghum with integration of 1st and 2nd generation (1G/2G) biorefining, thus comprising the integrated conversion of primary and secondary soft lignocellulosic biomass. In particular, methods of processing sugar cane and/or sweet sorghum feedstock are disclosed, said methods comprising the steps of providing raw juice from the feedstock, recovering a residual bagasse, pretreating the bagasse and mixing it with some quantity of raw juice, and hydrolyzing the pretreated bagasse enzymatically.
