Process schemes. Process schemes of: A) direct AD (Scenarios AD and AD-R), B) steam pretreatment prior to AD (Scenarios SP-AD and SP-AD-R), and C) combined ethanol and biogas production (Scenarios Et-AD and Et-AD+). The dashed lines in Figures A and B show flows that are used in Scenarios AD-R and SP-AD-R. Water (not shown) is used for dilution in Scenarios AD and SP-AD. Effl.: effluent, YC & SSF: yeast cultivation and simultaneous saccharification and fermentation.
