In this study, the effects of glycerol pretreatment on subsequent glycerol fermentation and biomass fast
pyrolysis were investigated. The liquid fraction from the pretreatment process was evaluated to be feasible
for fermentation by Paenibacillus polymyxa and could be an economic substrate. The pretreated biomass
was further utilized to obtain levoglucosan by fast pyrolysis. The pretreated sugarcane bagasse
exhibited significantly higher levoglucosan yield (47.70%) than that of un-pretreated sample (11.25%).
The promotion could likely be attributed to the effective removal of alkali and alkaline earth metals by
glycerol pretreatment. This research developed an economically viable manufacturing paradigm to utilize
glycerol comprehensively and enhance the formation of levoglucosan effectively from lignocellulose.
