“…Methanogenic bacteria that participate in the fermentation process are sensitive to the pH of the environment. Methanogenic bacteria and other anaerobic organisms usually perform best in environments with a pH of 8-8.6 (Wang et al, 2023;Xie et al, 2023). During the experiments, the materials inside the digesters were sampled and the pH level was measured, and the results were reported in Fig.…”

Biomass energy is a type of renewable energy and animal waste is one of the main resources for its production. Anaerobic digestion is a method for biological treatment of organic waste, which nowadays plays an important role in refining and reusing wet and degradable waste materials due to the production of environmentally friendly materials and energy recovery. The process of anaerobic digestion takes place in oxygen-free conditions inside reactors called anaerobic digesters and produces a substance called biogas. The purpose of this study is to investigate the effect of raw material type (cow and chicken manure) and the type of reactor (digester) on the biogas produced by measuring the amount of methane in the product. Three types of digester (metal, simple PVC and PVC with leachate rotation) with the same volume (10 Liter) were prepared. Equipment was installed on the digesters to measure the pH and volume of produced gas. The experiments were carried out in controlled temperature conditions (28–30 ºC) and in two stages. The first experiment was to load the digesters with cow excrement and the second experiment was to load the digesters with chicken excrement. In both experiments, the digesters were fed with 1.5 kg of animal manure and water with a ratio of 1:1. During a period of 60 days, the volume of biogas and methane produced was measured and recorded. The results showed that the amount of biogas produced from chicken waste is more than the amount obtained from cow waste. However, the amount of methane produced using cow excrement was more than that of chicken excrement. Also, the performance of PVC digester with leachate rotation was better than the other two digesters, which could be due to the mixing of raw materials in this type of digester.

“…Another promising direction in the transformation of Miscanthus into biofuel is the pretreatment of Miscanthus biomass followed by methane fermentation in order to generate biogas [ 44 , 56 , 57 , 58 ]. Dębowski et al [ 59 ] reported a study in which microalgae biomass and Miscanthus giganteus were co-fermented.…”

Carbon neutrality is a requisite for industrial development in modern times. In this paper, we review information on possible applications of polymers from the energy crop Miscanthus in the global industries, and we highlight the life cycle aspects of Miscanthus in detail. We discuss the benefits of Miscanthus cultivation on unoccupied marginal lands as well as the rationale for the capabilities of Miscanthus regarding both soil carbon storage and soil remediation. We also discuss key trends in the processing of Miscanthus biopolymers for applications such as a fuel resources, as part of composite materials, and as feedstock for fractionation in order to extract cellulose, lignin, and other valuable chemicals (hydroxymethylfurfural, furfural, phenols) for the subsequent chemical synthesis of a variety of products. The potentialities of the biotechnological transformation of the Miscanthus biomass into carbohydrate nutrient media and then into the final products of microbiological synthesis are also examined herein.

“…In AD biogas technology, organic wastes are decomposed in a closed vessel or compartment by different microbial consortia in an oxygen-free environment that produces biogas and digestate slurry, which can be used as an energy source and an organic fertilizer, respectively [2]. Biogas generally consists of 50%-70% CH 4 , 30%-40% carbon dioxide (CO 2 ), and other trace gases, including hydrogen sulfide; however, biogas composition varies depending on the substrate used [3]. The AD process is accomplished with four steps of organic waste degradation and byproduct utilization: hydrolysis, acidogenesis, acetogenesis, and methanogenesis [4].…”

“…Temperature is one of the key operational parameters affecting the performance of AD. Depending on the temperature range, the AD process is categorized as thermophilic (45 • C-65 • C), mesophilic (30 • C-40 • C), and psychrophilic (10 • C-25 • C or <25 • C) [3], with mesophilic as the optimum range for biogas production [5]. A low process temperature normally reduces microbial activity during the AD process, resulting in reduced biogas production.…”

Low-income countries have long benefited from household biogas plants for extracting clean energy and fertilizer. Despite the popularity, such ordinary plants do not have heating systems and suffer lower biogas production in cold regions or cold winters. This paper attempts a comprehensive review on research and development of household biogas technology in cold climate. This review specifically highlights the influence of temperature on biogas production, and technologies and recent advances in psychrophilic biogas production. Such measures are introduction of adapted inoculums, maneuvering operational parameters like hydraulic retention time (HRT) and organic loading rate (OLR), co-digestion approach and additives and digester designs. In addition to that, the review portrays adoption of low-cost heating arrangements including construction of greenhouse over bio-digesters, digester insulation, and integration of solar heating is crucial to enhance biogas production. Furthermore, this review identified gaps in the operation of bio-digesters under psychrophilic temperature in low-income countries and recommends operational consistencies in full scale psychrophilic biogas plants through development of standards, operational guidelines, and users' trainings.
