MOESM1 of Integrated experimental and technoeconomic evaluation of two-stage Cu-catalyzed alkaline–oxidative pretreatment of hybrid poplar

Additional file 1: Table S1. Raw material prices considered in the technoeconomic analysis. Table S2. Operating conditions considered for technoeconomic assessment of industrial scale bioethanol plant utilizing two stage Cu-AHP preteatments. The first three columns use data that were collected during this investigation. Entries in the fourth column, for the best-case, assume that glucose and xylose yields from the “120 °C NaOH-H2O PE + Cu-AHP case” remain unchanged when hydrogen peroxide, 2,2ʹ-bipyridine (bpy), and enzyme loadings are reduced. Table S3. Comparison of raw material costs (MM $/year) for 60 MM gal/year bioethanol plant utilizing two-stage Cu-AHP pretreatments. Table S4. Total capital investments of 60 MM gal/year bioethanol plant utilizing two-stage Cu-AHP pretreatments. Figure S1. Block flow diagram of the biorefinery. Figure S2. Process flow diagram of pretreatment unit including first stage (a) 30 °C NaOH-H2O PE, (b) 120 °C NaOH-H2O PE, and (c) 120 °C NaOH-EtOH PE followed by second stage Cu-AHP pretreatment.
