“…Generally, an anaerobic biological treatment method was also widely applied for agricultural organic waste treatment. It not only solved the excessive accumulation of agricultural organic waste but also produced clean energy, thereby realizing the recycling and harmless treatment of organic waste [7][8][9]. According to the widely accepted theory of four stage anaerobic fermentation, the anaerobic digestion process was composed of hydrolysis, acidogenic fermentation, H 2 -producing acetogenesis, and methanogenesis [10].…”

In this study, the influence of temperature on biogas production efficiency and the microbial community structure was investigated in a two-phase anaerobic digestion reactor for co-digestion of cow manure and corn straw. The results illustrated that the contents of solluted chemical oxygen demand (SCOD) and volatile fatty acid (VFA) in the acidogenic phase and biogas production in the methanogenic phase maintained relatively higher levels at temperatures ranging from 35-25 • C. The methane content of biogas production could be maintained higher than 50% at temperatures above 25 • C. The microbial community structure analysis indicated that the dominant functional bacteria were Acinetobacter, Acetitomaculum, and Bacillus in the acidogenic phase and Cenarchaeum in the methanogenic phase at 35-25 • C. However, the performances of the acidogenic phase and the methanogenic phase could be significantly decreased at a lower temperature of 20 • C, and microbial activity was inhibited obviously. Accordingly, a low temperature was adverse for the performance of the acidogenic and methanogenic phases, while moderate temperatures above 25 • C were more conducive to high biogas production efficiency.

“…According to Mata-Alvarez et al (2014), sewage sludge treatment is one of the oldest of applications. Dahiya & Joseph (2015) reported that biogas technology is generally used for waste management, and that all other options are either energy intensive, inconvenient or environmentally unsafe. Biogas technology is environmentally friendly, and has been adopted and is being used in many countries.…”

The current status of biogas technology in Ghana, a developing country, was explored focusing on factors affecting dissemination of the technology and the associated challenges. Data collection was by personal interview and physical observations, and was conducted between July and October 2017. Non-probabilistic sampling procedures were used to select 61 respondents from 162 users, while 54 digesters were selected from 120 digester sites. The findings revealed that: initial installation and maintenance costs appear high; the needs of most biogas users had not been fully met, thus, they were only partially satisfied with the outcome of the technology; and 21% of the biogas service providers were engineers and 79% from other disciplines (plumbers, masons, carpenters, and graduates from arts, social sciences, business, etc.). These factors affect technology diffusion. In addition, bottlenecks for more intense use of biogas technology that need to be addressed include lack of government subsidies or financial support, poor or unstandardized digester design, lack of gas production, lack of follow-up, lack of maintenance, lack of monitoring, and market value for bio-fertiliser (digestate). It is recommended that financial institutions support individuals and institutions with soft loans to acquire biogas digesters/plants, and that a regulatory body be formed for the activities of biogas service providers in developing countries.

“…Biomethane production from FW is probably one of the most investigated technology over the years (Dahiya et al, 2018). Over the years, various advancements in research focusing production of biogas have prompted the evolution of bio‐methanation technology with enhanced process efficiency (Dahiya & Joseph, 2015). Algapani et al investigated the biohydrogen and biomethane production from FW in a two‐stage anaerobic digestion process with digestate recirculation (Algapani, Qiao, di Pumpo, et al, 2018; Algapani, Qiao, Ricci, et al, 2018).…”

Food waste is the outcome of different food processing practices that have not been reused and are disposed of as waste. Food wastes are rich in a wide variety of organic constituents including starches, proteins, oils, fats, phosphates, nutrients, amino acids, and natural acids. Food waste is a zero‐value and nonconsumable resource. In this context, the valorization of food waste to different sorts of biofuels, for example, biodiesel, bioethanol, biohydrogen, bio‐oil, biochar, and biomethane by employing well‐structured and efficient valorization technologies can be an attractive and viable approach to counter the current global energy crisis and in establishing a sustainable bioeconomy. This type of food waste management not only resolves the serious pollution problem but also helps to reduce the dependency of the energy sector on fossil fuels. This review discusses the characteristics of food waste, common strategies for food waste management, food waste as a feedstock, biofuels as a renewable energy source, valorization of food waste to various types of biofuels, microbes‐assisted valorization of food waste, biofuels and bioeconomy, and future scope and challenges in the valorization of food waste to biofuels.
