2.1. Preparation: setting system boundary and determining relevant
material, flow and processes
The system boundary of the model is shown in Fig. 1. This
research will focus on the flow of materials and waste through
starch production and ethanol production using cassava. In starch
production, the scope will cover all processes including washing,
rasping, extraction, separation, dewatering (two-stage separation)
and drying. In ethanol production, the scope will cover raw materials
preparation, liquefaction, fermentation, distillation and molecular
sieve dehydration
