Design of a sustainable biorefinery for the valorization of waste from the baker's yeast industry through process simulation: A case study for the production of animal feed, fertilizers, and biofuels from vinasse.

The present work deals with the biotechnological valorization of the vinasse through a sustainable biorefinery. The aim was to design and analyze, through process simulation, a biorefinery for the valorization of vinasse in products such as organo-mineral fertilizers, supplements for animal feed, and biogas. For this purpose, the SuperPro Designer software was used, and a modified hierarchical decomposition method was applied.
