Brazil, being one of the main beer producers, generates brewer’s spent grain as a main by-product of this industry, which is mainly composed of cellulose, hemicelluloses, lignin and extractives. The alkaline pretreatment of brewer’s spent grain received from two breweries is studied in this work, namely breweries Imperial (B1) and Colombina (B2). Factorial design (22) was realized with three experiments at the central point: contact time (30, 60, 90 min) and NaOH concentration (4%, 6%, 8%). It was found that the presence of extractives causes interference in the characterization of the material. The delignification process allowed obtaining materials with lower lignin percentages when higher NaOH concentrations were used, reaching percentages of lignin loss with values between 85-95%, in both materials, but for these conditions, the losses of cellulose were considerable – of 35-43%. Enzymatic hydrolysis of the pretreated materials achieved conversions greater than 70%, emphasizing that the greatest conversions were obtained with material B1, where almost the whole cellulose was hydrolyzed.

This work presents the simulation in Aspen Plusr of a process to obtain arabinoxylans (AX) from Brewer’s Spent Grain (BSG), which is the major byproduct of the brewing industry. The process is divided into two stages: alkaline pretreatment and enzymatic hydrolysis. These stages cover the extraction of proteins and AX from BSG using an alkaline pretreatment and enzymatic hydrolysis of the AX separated from the liquid stream to obtain xylose, i.e. the substrate required for the fermentation to xylitol. Simulation results show that xylose obtained corresponds to 8,5% of the dry weight of the raw material, obtaining a yield of 58%. Several streams of byproducts were obtained, such as proteins, polypeptides, amino acids, phenolic compounds and lignocellulosic residues that can be valorized in other processes. Simulation was performed in the context of a biorefinery in Colombia.
