Biohydrogen production is a promising alternative to replace fossil fuels in an environmentally friendly way. In addition to the many available renewable energy sources, the production of “colored” hydrogen and biohydrogen occupies an irreplaceable position due to the undeniable availability of biomass and the need to manage food waste (FW). This article presents the current state of biohydrogen production technology—examples on continents (America, Africa, Asia, Australia and Oceania) and in Europe in terms of the efficiency of dark methane fermentation (CH4). Biophotolysis processes leading to the production of biohydrogen are indicated: directly and indirectly. The mechanism of the fermentation process of obtaining hydrogen and two-stage hydrogen fermentation are presented. The novelty of this article is the development of innovative trends in the development of the biohydrogen industry in Europe. Various models of the biohydrogen process are presented for different raw materials and proportions of substrates used in co-fermenters. Researchers from China are the undisputed pioneers in the use of renewable energy sources. However, improved energy self-sufficiency and environmental impacts are reflected in the growing number of pilot installations operating in European countries. This also gives hope for rapid progress towards full animal and FW management also in Poland.

There are thousands of different rice cultivars available worldwide, and glutinous rice (Oryza sativa var. glutinosa), sometimes known as sticky rice, is one of the most well-known varieties. Glutinous Rice Husk (GRH) is categorized as lignocellulosic biomass obtained as a by-product of rice manufacturing. The GRH is residue with a substantial amount of cellulose, hemicelluloses, and lignin, but it is difficult to degrade GRH during anaerobic digestion or fermentation. This research aims to investigate the factors affecting the sugar production of GRH by subcritical water (SCW) pretreatment. It is expected that the sugar produced could increase biohydrogen production. The biohydrogen yield was compared between raw and SCW-treated GRH as a fermentation substrate. Response Surface Methodology (RSM) was utilized to determine the ideal parameters for the subcritical water pretreatment of GRH using a Central Composite Design in the Design Expert Software. SCW pretreatment with temperature (195°C), solid-to-liquid ratio (1:10), and reaction time (17.5 minutes) were selected for the optimum sugar production (647.2 mg/L total sugar) of GRH. This pretreatment improves hydrogen production during dark fermentation by increasing the availability of easily accessible simple sugars for microbes. Additionally, it improves the lignocellulosic structure of GRH to enhance the fermentation process. Dark fermentation with SCW-treated GRH (0.73 mL H2/g-TS) obtained higher hydrogen yield than raw GRH (0.09 mL H2/g-TS). These findings highlight the potential of SCW pretreatment as an effective strategy for maximizing hydrogen production from GRH and contributing to using lignocellulosic biomass for renewable energy applications.

Energy primarily comes from fossil fuels, which leads to environmental deterioration through increased carbon dioxide load and other greenhouse gases in the atmosphere. Renewable energy is a cheap alternative, and biomass, like municipal solid wastes (MSWs), can be suitably used for energy production. This paper reviews the impact of variations in MSW composition on its physical, chemical, and lignocellulosic properties. It further illustrates how these properties affect torrefaction products. It was observed that MSW can refer to either a combination of different waste types or independent wastes; hence, there is no standard composition of MSW. The variations in composition are responsible for fluctuating physical, chemical, and lignocellulosic properties. These properties, along with torrefaction process parameters, simultaneously affect the torrefied product, whereas lignocellulosic properties influence the biochar yield, and physical and chemical properties impact calorific value and ash content. Torrefying MSW containing low moisture content yields biochar with a high calorific value. Methods to improve the lignocellulosic properties of MSW have not been studied. Research is needed to assess the possibility of improving biochar yields in MSW by enhancing lignin percentages, possibly through blending MSW. A guide on the best blend combinations and ratios is required. Also, it is crucial to study optimal torrefaction process parameters.
