Popis: Decades have passed, facing the energy crisis and environmental pollution and researching various possible solutions to tackle them. The use of renewable sources and sustainable development processes is continuously under study to substitute conventional fossil fuels for environmental benefit. Amongst these, hydrogen is thought to be an ideal energy source with almost no hydrocarbon and carbon dioxide emissions and high energy output. Among the hydrogen production techniques, dark fermentation (DF) is a promising option for hydrogen production as it is less costly and has more energy recovery potential. The current study was designed to test the ability of kitchen waste, like potato peels, which is a common waste coming out of kitchens worldwide. The experiment demonstrates that the acidic pH of 4.5 at 40 °C yields maximum hydrogen in the bench-scale batch reactor. Hydrogen production from potato waste feedstock using sewage sludge inoculum has not been reported at this scale before. The actual results and their significance analysis by ANOVA also confirmed that fermentative hydrogen production from waste potato peels using sewage sludge inoculum is possible at a mesophilic temperature in a bench-scale batch fermenter.
