Industrial organic waste from food processing, livestock production, brewery, bakery, and other related industries is a renewable substrate for anaerobic digestion to produce methane (CH4) or with some process manipulation and control to produce hydrogen (H2). Type of waste, its strength, presence of any toxic compounds, and other specific characteristics affect the operating conditions such as organic loading rate, hydraulic retention time, substrate pretreatment, as well as the yield and the rate of H2 production from industrial waste. Therefore, they need to be optimized for each waste. Research is required on the modeling, cost analysis, economic evaluation, comparative studies about the effect of bioreactor design, as well as on combining several industrial wastes to prepare a well-balanced substrate for H2-producing mixed culture dark fermentation.
