This study demonstrated the influence of protein on biohydrogen production from carbohydrates, especially starch, by using different combinations of two model food wastes, rice as starch-rich and soybean residue as protein-rich food waste. It was found the maximum specific hydrogen production potential, 0.99 mol H2/mol initial starch as glucose, and the maximum specific hydrogen production rate, 530 ml H2/h g-VS, occurred at a starch/protein ratio of 1.7. The protein content in the initial food waste not only provided buffering capacity to neutralize the volatile fatty acids as concurrent products but also enhanced the hydrogen production by providing readily available organic nitrogen such as soluble proteins and amino acids to microorganisms.

Food waste is rich in starch or cellulose, which can be utilized as carbon source for fermentation. Hence, in this paper, different food wastes (vegetable, rice, corn, potato) were taken as substrate to evaluate their hydrogen yield potential. The characteristics of fermentation broth, cumulative hydrogen yield, and hydrogen production rate were investigated in the photo-fermentation bio-hydrogen production process. Modified Gompertz Model was utilized to deal with experiment data. Results showed that food waste can be effectively utilized by photosynthetic bacteria. Waste rice was determined to have the best hydrogen production capacity with hydrogen yield of 696 mL, and the maximum hydrogen production rate of 17.71 mL/h, the average hydrogen concentration was 55.78%.

Hydrogen can be produced by fermentation of organic wastes as a renewable CO2 emission free fuel. The production potential as a function of feed composition is investigated using the ADM1 and experimental data from the literature. Lactate and ethanol are included in the model as intermediates to simulate the bio-hydrogen production processes more closely. Simulated effects of carbohydrate to protein ratio in the feed on pH, H2, biomass and fatty acid production using standard model parameters compare quite well with experimental results. The overall hydrogen and biomass production corresponds well with measurements for some feeds and less for others. The maximum theoretical yield is significantly higher than the simulated and measured values and is highest when the feed consists of only carbohydrates. The analysis suggests that the modified ADM1 is capable of simulating the main mechanisms involved in biological hydrogen production processes, implying that the model can be used to identify, and find strategies to influence limiting factors in bio-hydrogen production processes. Model weaknesses regarding the acidogenesis processes are observed and areas for further improvements discussed.

Abstract. The effect of temperature on bio-hydrogen production by co-digestion of sewerage sludge with food waste and its two derivatives, i.e. noodle waste and rice waste, was investigated by statistical modelling. Experimental results showed that increasing temperature from mesophilic (37 °C) to thermophilic (55 °C) was an effective mean for increasing bio-hydrogen production from food waste and noodle waste, but it caused a negative impact on bio-hydrogen production from rice waste. The maximum cumulative bio-hydrogen production of 650 mL was obtained from noodle waste under thermophilic temperature condition. Most of the production was observed during the first 48 h of incubation, which continued until 72 h of incubation. The decline in pH during this interval was 4.3 and 4.4 from a starting value of 7 under mesophilic and thermophilic conditions, respectively. Most of the glucose consumption was also observed during 72 h of incubation and the maximum consumption was observed during the first 24 h, which was the same duration where the maximum pH drop occurred. The maximum hydrogen yields of 82.47 mL VS−1, 131.38 mL COD−1, and 44.90 mL glucose−1 were obtained from thermophilic food waste, thermophilic noodle waste and mesophilic rice waste, respectively. The production of volatile fatty acids increased with an increase in time and temperature in food waste and noodle waste reactors whereas they decreased with temperature in rice waste reactors. The statistical modelling returned good results with high values of coefficient of determination (R2) for each waste type and 3-D response surface plots developed by using models developed. These plots developed a better understanding regarding the impact of temperature and incubation time on bio-hydrogen production trend, glucose consumption during incubation and volatile fatty acids production.

Substrates have critical effect on efficiency and cost of hydrogen production technology. Tradition evaluation index system which based on hydrogen production rate and conversion rate has limitation in comparing the economic value of different substrates utilized in hydrogen production system. This paper studies emergy of a fermentative biohydrogen production technology, comparing different biomass: wastewater and sewage sludge, the municipal solid waste and lignocellulosic biomass when they are used as substrates. Net emergy yield ratio, environmental loading ration and emergy-based sustainability index are measured. According to these indices, it shows an important role in reducing hydrogen production cost by developing cheap substrates. The results shows, the values of three indices were best when municipal wastewater was used as a substrate, it can reduce hydrogen production cost dramatically, obtain hydrogen and purify water simultaneously, benefit the environment protection.

The production of volatile fatty acids increased with an increase in time and temperature from food waste and noodle waste reactors whereas it decreased with temperature in rice waste reactors. The statistical modelling returned good results with high values of coefficient of determination (R2) for each waste type when it was opted for the study of cumulative hydrogen production, glucose consumption and volatile fatty acid production. The 3-D response surface plots developed by the statistical models helped a lot in developing better understanding of the impact of temperature and incubation time.

As lignocellulosic biomass, the cornstalk should be pretreated before anaerobic fermentation for hydrogen production. In this study, HCl, NaOH and enzyme were employed for cornstalk pretreatment and the products were used for anaerobic biohydrogen production. Hydrogen yield and hydrogen production rate were investigated to optimize cornstalk pretreatment method. In addition, the economic effect and energy consumption were also considered to evaluate the pretreatment methods. The optimum cornstalk pretreatment method was soaking in 2% NaOH at 50°C for 48h with a hydrogen yield of 55.0 ml/g-TS and a hydrogen production rate of 6.5 ml/h/g-VS in anaerobic hydrogen production.

Biohydrogen production from organic solid waste has shown particular advantages over other methods owing to the combination of waste reduction and bioenergy production. In this study, biohydrogen production from the co-digestion of cattle manure and food waste was optimized in a mesophilic semi-continuous process. To maximize hydrogen production, the effects of the mixing ratio (the proportion of food waste in the substrate), substrate concentration, and hydraulic retention time (HRT) on the co-digestion were systematically analyzed using a Box–Behnken design. The results showed that strong interactive effects existed between the three factors, and they had a direct effect on the responses. Hydrogen was primarily produced via the butyrate pathway, which was accompanied by the competing heterolactic fermentation pathway. Propionate and valerate produced from lipids and proteins, respectively, were obtained along with butyrate. The optimal process parameters included a mixing ratio of 47% to 51%, a substrate concentration of 76 to 86 g L−1, and an HRT of 2 d. Under these optimal conditions, the hydrogen production rate and hydrogen yield were higher than 1.00 L L−1 d−1 and 30.00 mL g−1 VS, respectively, and the predicted results were consistent with the experimental data. The results indicate that the co-digestion of cattle manure and food waste is a practical and economically promising approach for biohydrogen production.
