The biorefinery section and chemical inputs will vary depending on the fermentation pathway.
The biorefinery section is further broken down into subsections.
The first subsection includes pretreatment and hydrolysis, and is the same for both fermentation pathways.
The models diverge in the second subsection as these processes are dependent on the fermentation pathway.
System boundaries along with aflow diagram of the two processes are shown in Fig. 1.
A detailed description of each section is included below.
Manufacturing and maintenance of all capital goods is excluded from the system boundaries.
