“…Finally, in light of the recent trend towards energy generation from waste a novel line of research involves experiments with paddy plant microbial fuel cells in soil mixed with compost. Cells with compost showed higher values of voltage and power density with time indicating the influence of compost on bio-electricity generation (Moqsud et al 2015).…”

“…Therefore, the intensity of sunlight affects the bioelectricity production in a CW‐MFC (Figure ). Moqsud et al showed that solar radiation affects the bioelectricity production in a CW‐MFC. They found that the voltage generated in a CW‐MFC using rice plants ( Oryza sativa ) was higher when the solar radiation was high.…”

Recent advances in constructed wetland‐microbial fuel cells for simultaneous bioelectricity production and wastewater treatment: A review

Summary The coupling of constructed wetlands (CWs) to microbial fuel cells (MFCs) has turned out to be a source of renewable energy for the production of bioelectricity and for the simultaneous wastewater treatment. Both technologies have an aerobic zone in the air‐water interface and an anaerobic zone in the lower part, where the anode and the cathode are strategically placed. This hybridization is a promising bioelectrochemical technology that exerts a symbiosis between plant‐bacteria in the rhizosphere of an aquatic plant, converting solar energy into bioelectricity through the formation of root exudates as an endogenous substrate and a microbial activity. The difference between CW‐MFC and MFC conventional lies in the bioelectricity and substrate production in situ, where exogenous substrates are not required for example wastewater. However, CW‐MFC can take organic content present in wastewater, promoting the removal of some pollutants. Different areas that comprise the study of a CW‐MFC have been explored, including the structures and their operation. This review aims to provide concise information on the state of the art of CW‐MFC systems, where a summary on important aspects of the development of this technology, such as bioelectricity production, configurations, plant species, rhizodeposits, electrode materials, wastewater treatment, and future perspectives, is presented. This system is a promising technology, not only for the production of bioenergy but also to maintain a clean environment, since during its operation, no toxic byproducts were formed.

Novel earthen pot–plant microbial fuel cells (PMFCs) are constructed as a wastewater filtering and microelectrical power system. Its performance is investigated at different influent chemical oxygen demand (COD) strengths of 50 mg L−1 (P‐COD50), 250 mg L−1 (P‐COD250), and 500 mg L−1 (P‐COD500). Two reference reactors, one unplanted with 250 mg L−1 (UP‐COD250) and another planted with tap water devoid of external supply of organic (P‐COD0), are constructed to show the effects of plants in treatment ability and electricity generation. Maximum average current density is achieved in P‐COD250, that is, 242 ± 10.5 mA m−2 followed by UP‐COD250, P‐COD50, P‐COD500, and P‐COD0. Polarization curves also depicts a similar order for power density. Variations of power output in low and high concentrated units are accompanied with lower substrates for bacteria in the former while the latter is due to osmotic shock of plants at higher COD concentration. At the same influent concentration, planted reactors enhances current density by 12.5%. Organic removal ability is promising in all the reactors, reaching almost 99%. However, plants enhanced, on average, 3% in COD removal. High COD removal is achieved with higher retention time. Planted reactors shows more significant increments in current during daytime after feeding than unplanted reactors, suggesting the role of root exudates via photosynthates in current generation. These results can help in further optimizing of PMFCs in terms of configuration and substrates.
