Short summary

The study focuses on co-digestion of food waste and its derivatives i.e. noodle waste and rice waste with sludge in order to produce bio-hydrogen. The pH was set at 7 initially and was not controlled throughout the incubation in order to make the process simple. Noodle waste produced maxim bio-hydrogen production as compared to food waste and rice waste. The increase in temperature increased the bio-hydrogen production for food waste but caused negative impact on noodle and rice wastes.
