Summary At present, the energy requirements of the world majorly depend on fossil fuels, but overconsumption leads to a serious energy crisis, and the greenhouse gases released during the burning of fossil fuel arouse various environmental issues like global warming, acid rain, etc. Biohydrogen is one of the promising fuel among the alternative sources of energy, because it can be derived from renewable sources, cost effective, high energy content, clean, and environmentally friendly fuel. Biohydrogen has been produced by various methods namely thermo‐chemical gasification, solar gasification, electrolysis of water, pyrolysis, steam reforming, and biofermentation. Among them, the biological way of hydrogen production is an environmentally friendly method and does not require any external energy, but beside hydrogen dark fermentation could also generate CO2 and other gases as by‐products, which could contribute to the greenhouse gas augmentation if not well‐controlled. But the quantity of hydrogen production through the photo and dark fermentation method is low, which is also a major constrain for commercialization. In order to overcome this obstacle, many researchers engaged them in the biohydrogen production with nanotechnology which is a potential technique for efficient biohydrogen production. Hence, this review is mainly focused to providing an update of nanotechnology in biohydrogen production and state‐of‐the‐art on its emerging field. In this regard, this review paper highlighted several new findings and achievements in biohydrogen production using both inorganic and organic nanoparticles. Additionally, the synthesis of sustainable and environmentally friendly green nanoparticles in biohydrogen production has been addressed.

The methane fermentation of organic waste is one way to minimize organic waste, which accounts for 77% of the global municipal waste stream. The use of biochar as an additive for methane fermentation has been shown to increase the production potential of biogas. Sulfur waste has a potential application to synergistic recycling in a form of composites with other materials including biochar. A composite product in the form of a mixture of biochar and molten sulfur has been proposed. In this experiment, additions of the sulfur–biochar composite (SBC) were tested to improve the fermentation process. The biochar was produced from apple chips under the temperature of 500 °C. The ground biochar and sulfur (<1 mm particle size) were mixed in the proportion of 40% biochar and 60% sulfur and heated to 140 °C for sulfur melting. After cooling, the solidified composite was ground. The SBC was added in the dose rate of 10% by dry mass of prepared artificial kitchen waste. Wet anaerobic digestion was carried out in the batch reactors under a temperature of 37 °C for 21 days. As an inoculum, the digestate from Bio-Wat Sp. z. o. o., Świdnica, Poland, was used. The results showed that released biogas reached 672 mL × gvs−1, and the yield was 4% higher than in the variant without the SBC. Kinetics study indicated that the biogas production constant rate reached 0.214 d−1 and was 4.4% higher than in the variant without the SBC.
