“…MSW has been shown to contain one-third to one-half the energy of coal per tonne which is enough to power a plant with the excess being sold to the national grid [114,115]. Therefore, as an efficient new source, the development of MSW treatment technology is necessary to realize the sustainable development of cities, and it is a good alternative energy technology for the future [116,117].…”

Renewable energy plays a significant role in the world for obvious environmental and economic reasons with respect to the increasing energy crisis and fossil fuel environmental problems. Biomass energy, one of the most promising renewable energy technologies, has drawn increasing attention in recent years. However, biomass technologies still vary without an integrated framework. Considering the theory of a technological paradigm and implementing a literature analysis, biomass technological development was found to follow a three-stage technological paradigm, which can be divided into: BETP (biomass energy technological paradigm) competition, BETP diffusion, and BETP shift. Further, the literature review indicates that waste, like municipal solid waste (MSW), has the potential to be an important future trend in the world and waste-to-energy (WTE) is designed for sustainable waste management. Among WTE, anaerobic digestion has the potential to produce energy from waste sustainably, safely, and cost-effectively. The new BETP technological framework proposed in this paper may offer new research ideas and provide a significant reference for scholars.

“…The substitutes for fossil fuel depletion are renewable energy resources such as biogas, solar, wind energy, etc. In recent years, an integrated biogas production and conversion process for sustainable bioenergy has been proposed and analyzed [2]. It is noteworthy that biogas production via anaerobic digestion proves to be a cheap, environment-friendly, and sustainable energy source [3][4][5].…”

Anaerobic granules are responsible for organic degradation and biogas production in a reactor. The biogas production is entirely dependent on a mass transfer mechanism, but so far, the fundamental understanding remains poor due to the covered surface of the reactor. The study aimed at investigating the fundamental mass transfer characteristics of single anaerobic granules of different sizes using microscopic imaging and analytical monitoring under single and different organic loadings. The experiment was conducted in a micro reactor and mass transfer was calculated using modified Fick’s law. Scanning electron microscopy was applied to observe biogas production zones in the granule, and a lab-scale microscope equipped with a camera revealed the biogas bubble detachment process in the micro reactor for the first time. In this experiment, the granule size was 1.32, 1.47, and 1.75 mm, but 1.75 mm granules were chosen for further investigation due to their large size. The results revealed that biogas production rates for 1.75 mm granules at initial Chemical Oxygen Demand (COD) 586, 1700, and 6700 mg/L were 0.0108, 0.0236, and 0.1007 m3/kg COD, respectively; whereas the mass transfer rates were calculated as 1.83 × 10−12, 5.30 × 10−12, and 2.08 × 10−11 mg/s. It was concluded that higher organic loading and large granules enhance the mass transfer inside the reactor. Thus, large granules should be preferred in the granule-based reactor to enhance biogas production.

“…Water hyacinth (Eichhornia crassipes) is useful in bioenergy production (Bergier, Salis, Miranda, Ortega, & Luengo, 2012;Huang, 2015) and waste water treatment (Huang, 2015;Todd & Josephson, 1996). In addition, it is used as vegetables in many countries due to its high carotene content and the presence of various secondary metabolites like terpenoids and alkaloids (Lalitha, Sripathi, & Jayanthi, 2012).…”

Background Channa punctata, Indian spotted snakehead, has a great economic value in south and south-east Asia being an important protein source for humans. Fish cultures are affected due to various bacterial and viral infections. Vibrio harveyi is a fish pathogenic bacteria which causes several outbreaks throughout the world and leads to huge mortalities. In this study, leaves of Eichhornia crassipes (water hyacinth) were used to investigate its immunostimulatory potential in Channa punctata. Results The immunostimulatory effects of water hyacinth leaves were studied in fish fed with 2.5% and 5% supplementary feed (experimental groups) in comparison to normal feed (control groups). Gas chromatography mass spectrometry (GC-MS) analysis of E. crassipes methanol extract showed presence of various components which have immunostimulatory, antioxidant, antibacterial, and anti-inflammatory activities. The antibacterial activity, antioxidant potential, and presence of phenol and flavonoids in methanol and ethanol extracts supported its use in fish feed. The healthy acclimatized fish were challenged with V. harveyi weekly. Liver function tests, alkaline phosphatase levels, and immunoglobulin content in the experimental groups were improved with respect to those in the positive control group. The spleen and head kidney were obtained at the final day of experiment, and macrophages were isolated; higher percentage of phagocytosis and phagocytic index indicated enhanced cell-mediated immune response in fish due to supplemented feed. Conclusion Plant-infused feed with leaves of E. crassipes can be recommended as a regular feed supplement to enhance fish immunity and disease resistance against the V. harveyi infection.
