Most of lignin and hemicellulose was removed while keeping cellulose intact when wastepaper was pretreated using ethylene glycol at 150℃ and 2% sulfuric acid for 15 minutes. Also, enzymatic digestibility of 94% was achieved, which was 20% higher than those of conventional
pretreatment methods. Despite of these advantages, the high price of ethylene glycol could be a problem to use it as a pretreatment reagent. To overcome this problem, the recycle and reuse of ethylene glycol was studied. The dissolution yield, the cellulose, hemicellulose and lignin
removals, the ultimate cellulose recovery (residual cellulose fraction after retreatment*enzymatic digestibility), and the solvent viscosity were investigated as a function of number of recycles for the ethylene glycol solvent.
