Integrated process yield of fermentation products if individual yields in this study were extrapolated to 1 dry tonne of poplar (Pop). Every DDR condition of poplar yielded less than 100 kg of fermentation products. The theoretical maximum overall product yield from corn stover is 300 kg. X/Y/Z represents NaOH conc (g/kg)/residence time (min)/disc-refining gap (in.)
