The impact of continuous removal of volatile fatty acids on fermentative hydrogen production from food waste (FW)in a Continuously Stirred Tank Reactor (CSTR)was evaluated. Two experimental phases were conducted, a control phase and one in which volatile fatty acids were removed continuously from the reactor for the first time by electrodialysis (ED). Hydrogen yields were 64.7 cm3 H2/g VS and 227.3 cm3 H2/g VS for control phase, and ED phase respectively. Continuous removal of volatile fatty acids during fermentation not only increased H2 yields but increased the production of volatile fatty acids (a valuable chemical feedstock)from 0.14 g/g VS to 0.34 g/g VS.
