“…The substantial amount of research aimed at seeking alternative energy sources worldwide has led to the discovery of biofuels, which are major competitors of fossil fuels in terms of availability and efficiency (Afolalu et al , 2021; Samuel et al , 2021a; Samuel et al , 2021b; Soudagar et al , 2020). One of the main reasons for investing in renewable sources is the environmental benefits of this type of energy, which is directly related to sustainable development (Nwaokocha et al , 2020). The origin of the term sustainability is related to ecology and economics areas; through ecology, there is evidence that ecosystems can restore their functions in the face of anthropic and natural aggressions.…”

Purpose This paper aims to examine the relationships between socioeconomic development, renewable energy and the innovative process by providing: a descriptive analysis; a co-occurrence analysis of terms, thematic mapping and conceptual structure; and the typology of the textual corpus. Design/methodology/approach To analyze the relationship between “renewable energies, socioeconomic development and the innovative process,” it is necessary to build a theoretical foundation that contains the relevant scientific studies and reflects the current state of the art on the subject. For this, this study developed a systematic literature review (SLR) using the preferred reporting items for systematic reviews and meta-analyses research protocol to answer the relationship on the theme. Findings Research shows a global understanding of the need to invest in developing studies to reduce carbon dioxide emissions and improve economic growth. The main contributions lie in providing a typology of the state of the art, identifying the joint relationships between themes, insights into the key themes and indicating themes that must be developed. This study may also support future empirical studies as it provides a theoretical foundation for formulating hypotheses, which can be tested through qualitative and quantitative approaches. Originality/value The innovative character consists of addressing a shortage of SLRs on this theme. Thus, this paper fills this gap by providing a theoretical foundation for future scientific and academic knowledge generation. Furthermore, regarding the interdisciplinary aspects of this research as contributions, this paper presented different approaches and theoretical perspectives.

“…Older and recent studies like refs. [60,188], and [189] explored the use of conventionally used electrode materials including carbon; materials that are derived from carbon such as plain carbon paper, carbon rod, carbon fiber, carbon cloth, carbon sheet, graphite rod, graphite sheet, graphite fibers, graphite cloth, and graphite brushes; metal/metal oxides (gold (Au), copper (Cu), aluminum (Al), silver (Ag)); and several conducting polymers. However, all of these materials were either not biocompatible or could not deliver the desired results in terms of conductivity [190].…”

The increasing demands of efficient and sustainable energy generation methods from waste products have taken a giant leap in the last century, and especially in the previous two decades. Wastewater treatment has also been a much-researched topic in recent years owing to the exponential increase in effluent-laden wastewater from industries, the agricultural sector and food sector, and its effects on the environment. There have been plenty of wastewater treatment techniques over the years, but most of them lack in terms of cost-effectiveness, durability, and energy recovery rates. Microbial fuel cells can prove to be of great use to tackle both of these issues in one go, as they perform bioelectrochemical processes on organic biodegradable compounds to oxidize them to generate power which can be harnessed by various means. This article explains the aim, construction, mechanism, and application of microbial fuel cells; the economic and scientific challenges that they face in the future; and microbial fuel cell (MFC) hybrid systems which make use of MFCs combined with other useful technologies for greater aims and better efficiencies. It overall discusses the various ways in which MFCs outperform other wastewater treatment technologies by significantly decreasing sludge production and being environment-friendly, and also some limitations and drawbacks that MFCs face owing to the fact that they are relatively newer technologies and still require decades of modifications until they reach excellent output rates. MFCs are known not only for wastewater treatment but also for contaminant removal, heavy metal removal, biohydrogen production, applications in biosensors, etc., as also discussed in this article.

“…It is important to note that these results contribute to our understanding of the MFC's performance and the variation in its efficiency over multiple operational cycles. One relevant study by Nwaokocha et al (2021) explored a similar MFC setup using a Nigerian corn starch wastewater as substrate. The research demonstrated a much lower current and power densities of 8.10 mA/cm 2 and 7.7 mW/cm 2 respectively than the findings of this present study.…”

“…A total of 682 mW/m 2 of power was produced. The use of Nigerian corn starch wastewater as a substrate for a dualchamber MFC setup using Iron electrodes was investigated by Nwaokocha et al, (2021). In 9 days of the experiment, 1.43 mA current, 0.97 V, a maximum current density of 8.10 mA/m 2 , and a maximum power density of 7.7 mW/m 2 were achieved.…”

Microbial fuel cells (MFCs) have shown promise as a sustainable technology for wastewater treatment and energy recovery. In this study, cattle dung was used as an inoculum and kitchen waste (KW) from Dutse urban, Nigeria was used as a substrate for bioelectricity generation in MFC. The MFC was operated in a fed-batch mode over 37 days, spanning three cycles. During characterization, the chemical oxygen demand (COD) of the KW was found to be 30421 ± 124 mg/L, indicating a high concentration of organic pollutants. The MFC's performance was evaluated based on the voltage generated, with the first cycle reaching a peak of 254 mV, the second cycle 247 mV, and the third cycle 242 mV. Current and power densities during the three cycles decreased gradually from 66.84 mA/m² and 16.84 mW/m² in the first cycle to 63.68 mA/m² and 15.41 mW/m² in the third cycle respectively. Furthermore, there was a notable reduction in COD from the influent diluted from initial measured COD, from 1120 ± 63 mg/L to an effluent level of 226 ± 49 mg/L, indicating approximately 80% removal rate. The pH of the anolyte progressively dropped with each cycle, reflecting the metabolic activities of bacteria in the anode chamber. The findings underscore MFC's potential for organic waste management and electricity generation, with results outperforming some contemporary studies.
