Abstract
Abstract >> This study was conducted to evaluate the characteristics of mesophilic fermentative H 2 productionfrom food waste which was treated by food waste disposer. It was found that H 2 yield and lag phase were affectedby particle size of food waste. The H 2 yield decreased with increasing particle size while lag phase increased.The maximum H 2 yield was found 0.584±0.03 mol H 2 /mol hexose at particle size smaller than 0.30 mm. TheH 2 production rate was also affected by chemical composition of food waste. The H 2 production rate linearly decreased with increasing proteins to carbohydrates ratio(P/C ratio) where the maximum value was 0.031±0.006mol H 2 /mol hexose·h at 0.17.
