- 1 Refers to stillage separation in the reference case and in scenarios A1-A4 and to separation of the effluent of AD in scenario B.
- 2 Includes the flue gas condenser for scenarios with district heating (A2-A4 and B).
- A summary of the scenarios is given in Table 1.
- AD: anaerobic digestion; CHP: combined heat and power production; SSF: simultaneous saccharification and fermentation.
