- *Solid removal (%) = 100% × (1- Total solid after pretreatment (g)/Total solid before pretreatment (g)).
- Xylan removal (%) = 1- (%Xylan in pretreated solids / % Xylan in raw biomass) × Solid yield.
- Lignin removal (%) = 1- (%Lignin in pretreated solids / % Lignin in raw biomass) × Solid yield.
- L/S - liquid to solid.
