An Updated Review of Recent Applications and Perspectives of Hydrogen Production from Biomass by Fermentation: A Comprehensive Analysis

“…This reuse not only opens space for the creation of production centers in urban areas but also contributes to reducing the logistical costs associated with transporting waste [134], which is considered a challenge, as we have discussed in previous sources. However, to ensure the efficiency of this process, rigorous selection processes to control contamination and to perform prior treatments on organic wastes must be implemented [135][136][137]. In addition, urban restrictions and regulations that may affect both the collection and use of these wastes in hydrogen production must be considered [135,137].…”

“…In the last 10 years, many research centers worldwide have turned their attention to the development of alternative renewable/green energy sources [156][157][158]. Due to the scarcity of energy resources and the rise in prices of foods such as corn and sugar [135,156,[158][159][160], researchers are looking for new renewable energy sources [156,159]. One approach is to convert agricultural waste into hydrogen through sustainable methods such as fermentation.…”

“…The author also reports that due to insufficient oil reserves, many specialized centers have turned their attention to green hydrogen, which is one of the most promising alternatives for this energy source. Based on the study of the JORDAN PETROLEUM REFINERY COMPANY (JPRC), the demand for pure hydrogen reaches 700 kg/h (5.88 million kg/year), which is consumed in hydrotreating and hydrocracking processes [70,135,159,163]. This order of magnitude is justified by the scarcity of non-renewable energy resources and the high cost of other sources.…”

Effect of granulation on chlorine-release behavior during municipal solid waste incineration

“… 9 Not only in furnace at 500–850 °C but also in flue at 200–500 °C, HCl/Cl 2 provide chlorine for dioxins production by high-temperature gas-phase reaction mechanism and “ de novo ” synthesis mechanism. 10 …”
