Abstract

In order to utilize crude glycerol, a byproduct from biodiesel fuel production, its conversion through anaerobic fermentation was examined. It was found that crude glycerol enhances hydrogen production while suppressing methane fermentation. Characteristics of the anaerobic fermentation with crude glycerol were examined. There existed an optimum crude glycerol concentration when it was digested with an inoculum of cattle excrement origin.
