“…In this study, both chambers were connected with Nafion PEM. Based on the results, the energy outputs from different layers of sugarcane bagasse and banana peel were similar (5.5-6 V) [115]. These results refer to the similarity of the cellulose-based composition of sugarcane bagasse and banana peel.…”

The rise in population, urbanization, and industrial developments have led to a substantial increase in waste generation and energy demand, posing significant challenges for waste management as well as energy conservation and production. Bioenergy conversions have been merged as advanced, sustainable, and integrated solutions for these issues, encompassing energy generation and waste upcycling of different types of organic waste. Municipal solid waste (MSW) and agricultural residues (AR) are two main resources for bioenergy conversions. Bioenergy production involves feedstock deconstruction and the conversion of platform chemicals to energy products. This review provides a detailed overview of waste sources, biofuel, and bioelectricity production from fermentation and microbial fuel cell (MFC) technology, and their economic and environmental perspectives. Fermentation plays a critical role in liquid biofuel production, while MFCs demonstrate promising potential for simultaneous production of electricity and hydrogen. Fermentation and MFCs hold a significant potential to be integrated into a single pipeline, enabling the conversion of organic matter, including a variety of waste material and effluent, into diverse forms of bioenergy via microbial cultures under mild conditions. Furthermore, MFCs are deemed a promising technology for pollutant remediation, reducing COD levels while producing bioenergy. Importantly, the consolidated fermentation–MFC system is projected to produce approximately 7.17 trillion L of bioethanol and 6.12 × 104 MW/m2 of bioelectricity from MSW and AR annually, contributing over USD 465 billion to the global energy market. Such an integrated system has the potential to initiate a circular economy, foster waste reduction, and improve waste management practices. This advancement could play a crucial role in promoting sustainability across the environmental and energy sectors.

“…This study resulted in 331.9 mW/m 2 of energy output and 35-38% of organic degradation [114]. Comparative studies among different AR, including sugarcane bagasse and banana peels, were carried out with DC-MFCs coupled with a carbon fiber tissue electrode [115]. In this study, both chambers were connected with Nafion PEM.…”

“…Current output was plotted against time (days). Adapting phase can be seen in the beginning of the graph which shows a decrement indicating that bacteria is still in the process of adapting to the new environment (William et al, 2019). Yaqoob et al (2021) mentioned that, during this phase, electrocatalytic activities is low due to the poor bacteria densities on anode surface.…”

Aims: Banana peel (BP) waste is still underutilized in Malaysia, which can be used as source of renewable energy. Microbial fuel cell (MFC) is a device that utilizes biomass to convert chemical energy into electrical energy with help of the microbial catalysis. The present study evaluates the current generation of MFC supplemented with BP waste as substrate for Pseudomonas aeruginosa ATCC 27853. Methodology and results:The CHNS result shows that the C:N ratio of BP is 27:1 which is within the optimum C:N ratio for the microbial food requirement. Fluctuation of current increases as concentration of banana peel extract (BPE) decreases from 1:10, 1:20, 1:40 and 1:80, thus making 1:10 BPE optimum. Current fluctuation is related to microbial activity due to the sufficiency of nutrients which subsequently affect the performance of MFC. BPE and banana peel slurry (BPS) comparison shows that BPS is optimum. BPE reaches a maximum current of 3.91 µA in ascending phase which is higher compared to BPS (3.65 µA). In descending phase, BPE current drops to 2.31 µA compared to 2.98 µA of BPS. In stationary phase, BPS able to maintain a higher current compared to BPE. MFC maximum current was doubled to 6.52 µA when PEM was treated priorly. Conclusion, significance and impact of study: Besides exploring and improving the ability of MFC as an alternative for power production other than fossil fuel, this research also encourage society to fully utilize waste as a source of renewable energy instead of throwing it into garbage without productivity.
