“…Among these options, co-digestion of more than one feedstock has been reported to be very successful in overcoming the challenges associated with mono-feedstock digestion. Co-digestion results in higher biogas yields, improved digester stability and, in particular, the combination of multiple feedstocks with their unique properties provides a more balanced nutrient composition, a diversified microbial community and better buffering capacity against the accumulation of VFAs [124]. For example, Ihoeghian et al [125] investigated the codigestion of cattle rumen content and food waste.…”

Human and animal waste, including waste products originating from human or animal digestive systems such as urine, feces, and animal manure, have constituted a nuisance to the environment. Inappropriate disposal and poor sanitation of human and animal waste often cause negative impacts on human health through contamination of the terrestrial environment, soil, and water bodies. Therefore, it is necessary to convert these wastes into useful resources to mitigate their adverse environmental effect. The present study provides an overview and research progress of different thermochemical and biological conversion pathways for the transformation of human- and animal-derived waste into valuable resources. The physicochemical properties of human and animal waste are meticulously discussed as well as nutrient recovery strategies. In addition, a bibliometric analysis is provided to identify the trends in research and knowledge gaps. The results reveal that the U.S.A, China and England are the dominant countries in the research areas related to resource recovery from human or animal waste. In addition, researchers from the University of Illinois, the University of California Davis, the Chinese Academy of Science and Zhejiang University are front runners in research related to these areas. Future research should be centred on developing technologies for the on-site recovery of resources, exploring integrated resource recovery pathways, and exploring different safe waste processing methods.

“…Above all, raising a positive attitude toward FW prevention in the community is more sustainable than any other advanced FW management. Beyond that, the FW physicochemical properties can easily be changed, as it easily susceptible to natural elements and fluctuations in weather conditions (Awosusi et al, 2021). This could be exacerbated by poor storage and sourceseparated collection facilities.…”

Advancing the bioconversion process of food waste into methane: A systematic review

“…The antagonistic effect is caused when incompatible feedstocks are co-digested [72], and, if α = 1, the interaction between co-substrates is unclear [43]. This parameter is used to indicate the performance of the process; however, it is not used to indicate the maximum methane yield, which means that the maximum synergistic index does not promise the highest methane yield [83,84]. Accordingly, both specific methane yield and the synergistic index can be measured to decide the optimum mixing ratio in AcoD.…”

Impacts of Anaerobic Co-Digestion on Different Influencing Parameters: A Critical Review

Lignocellulosic feedstocks are year-round, available bio-residues that are the right candidates for counteracting the energy crises and global warming facing the world today. However, lignin leads to a slow hydrolysis rate and is a major bottleneck for biogas production via anaerobic digestion. Anaerobic co-digestion (AcoD) is an economical method available, which overcomes the limitation of a single feedstock’s properties in an anaerobic digestion process. This paper critically reviews the impacts of co-digestion on lignocellulosic biomass degradation, process stability, various working parameters, and microbial activities that improve methane yields. A combination of compatible substrates is chosen to improve the biomethane yield and conversion rate of organic matter. AcoD is a promising method in the delignification of lignocellulosic biomass as an acid pretreatment. Ultimate practices to control the impact of co-digestion on system performances include co-feed selection, in terms of both carbon-to-nitrogen (C/N) and mixing ratios, and other operating conditions. A detailed analysis is performed using data reported in the recent past to assess the sensitivity of influencing parameters on the resultant biogas yield. For the investigators motivated by the basic principles of AcoD technology, this review paper generates baseline data for further research work around co-digestion.
