Optimization of simultaneous production of volatile fatty acids and bio-hydrogen from food waste using response surface methodology.

ABSTRACT: Anaerobic digestion of food waste (FW) is commonly considered an effective and green technology to convert solid waste into valuable feedstock including volatile fatty acids (VFAs) and hydrogen. Response surface methodology (RSM) was selected to analyze the production of VFAs and hydrogen from food waste in a batch process. The effect of the three variables i.e. total solid content (TS), pH, and reaction time under each variable at three levels on VFAs and hydrogen production was assessed. The optimum conditions determined via RSM were pH = 7.0, TS = 100 g L^-1, and reaction time = 3 d. The maximum VFA and hydrogen production was 26.17 g L^-1 and 46.03 mL g^-1 volatile solids added, respectively. The ratio of observed hydrogen (H_o) to
