Integrated process yield of fermentation products if individual yields in this study were extrapolated to 1 dry tonne of switchgrass (SWG). Every DDR condition of switchgrass yielded less than 150 kg of fermentation product. This is less than yields from corn stover, but more than poplar. X/Y/Z represents NaOH conc (g/kg)/residence time (min)/disc-refining gap (in.)
