Total monomeric sugar yields (as free sugars) per tonne of input wood as a function of steaming time from pilot scale trials. The refined pulps were vibratory ball-milled (60 min) and digested using Cellic CTec2 (5 FPU/OD g substrate) in the presence of 0.1% PEG. Monomeric sugar yields from the pressates were calculated from the pressate composition assuming the conversion efficiency shown in Fig. 3. Data for steaming times of 36 and 54 min to be reported separately
