We sat down with Srinivas Kasulla, Director of Arka BRENStech Pvt Ltd, to discuss the Indian biogas market, Arka’s partnership with BPC, and how to avoid process failure in large-scale biogas production. Can you tell us about Arka BRENStech and what services you offer? Arka BRENStech is a leading biogas engineering firm with a strong international presence and partnerships. We specialise ...
Hydrogen production by dark fermentation is one promising technology. However, there are challenges in improving the performance and efficiency of the process. The important factors that must be considered to obtain a suitable process are the source of the inoculum and its pre-treatment, types of substrates, the reactor configurations and the hydrogen partial pressure. Furthermore, to obtain ...
The feasibility of producing hydrogen from various industrial wastes, such as vinasses (sugar and tequila industries), and raw and physicochemical-treated wastewater from the plastic industry and toilet aircraft wastewater, was evaluated. The results showed that the tequila vinasses presented the maximum hydrogen generation potential, followed by the raw plastic industry wastewater, aircraft ...
The aim of this research was to study the feasibility of a fixed bed reactor for the production of biohydrogen by using tequila vinasse as substrate. The experiments were carried out in a continuous mode under mesophilic and acidic conditions. ...
The intent of the study was to determine whether the utilisation of biohydrogen from organic waste, as a transport fuel, can provide a holistic solution for municipalities to meet renewable energy and waste reduction targets in medium-sized towns. The study assesses the feasibility of producing a sufficient quantity and quality of biohydrogen from the organic ...
Cheese whey, potato and enriched potato (with additional glucose and CaCO3) are used as the production media and their hydrogen production results are compared in order to determine the best biohydrogen production media. Batch growth of anaerobic Clostridium butyricum for biohydrogen production is performed in 500 ml screw–capped bottles at 28°C. ...
This study was performed to investigate the influence of operational pH on dark H2 fermentation of food waste by employing anaerobic batch reactors. The highest maximum H2 yield was 1.63 mol H2/mol hexoseadded at operational pH 5.3, whereas the lowest maximum H2 yield was 0.88 mol H2/mol hexoseadded at operational pH 7.0. With decreasing operational pH values, the n-butyrate concentration ...
Molecular biology techniques provide valuable insights in the investigation of microbial dynamics and evolution. Denaturing gradient gel electrophoresis (DGGE) analysis is one of the most popular methods which have been used in bioprocess assessment. Most of the anaerobic digestion models consider several microbial populations as state variables. However, the difficulty of measuring individual ...
Anaerobic fermentation of press mud and sewage for biohydrogen production was conducted in six batch reactors for various total solid concentrations between 5–8.5%. Chemical oxygen demand, pH, total solid % for biohydrogen produced were monitored regularly. The experiments were conducted for 40 days to optimise the total solid content of the feed for maximum ...
As an ideal fuel due to the advantages of no pollution, high combustion heat and abundant sources, hydrogen gas can be produced from organic matter through the electrohydrogenesis process in microbial electrolysis cells. But in many MECs, platinum is often used as catalyst, which limits the practical applications of MECs. To reduce the cost of the MECs, Ni-based alloy cathodes were developed by ...
Anaerobic digestion is an effective technology to convert cellulosic wastes to methane and hydrogen. Heat-treatment is a well known method to inhibit hydrogen-consuming bacteria in using anaerobic mixed cultures for seeding. This study aims to investigate the effects of heat-treatment temperature and time on activated sludge for fermentative hydrogen production from α-cellulose by response ...
Hydrogen is found to be a clean energy source; biohydrogen has been researched in recent years. Anaerobic Digestion of Kitchen Waste (KW) for hydrogen production was performed in lab scale reactors, using heat-treated anaerobically digested biogas plant slurry. ...
The hydrogen production in the reactor with Clostridium acetobutylicum was estimated as 179.59 mL/kg TS/day in ambient temperature condition and 185.92 mL/kg TS/day in controlled temperature condition.Keywords: anaerobic digestion, kitchen waste, solid phase digestion, biohydrogen, biogas sludge, hydrogen production, waste ...
H2 is considered as the ultimate cleanest energy carrier to be generated from renewable sources. This minireview intends to point out that in addition to this function, biologically produced hydrogen is important for environmental biotechnological applications. The purple sulphur phototrophic bacterium, Thiocapsa roseopersicina BBS contains several NiFe hydrogenases. These enzymes can be used ...
