Clean energy generation using groundnut oil mill effluent with microbial fuel-cell

AbstractBiomass is one of the most abundant renewable energy resources on the earth, which is also considered as one of the most promising alternatives to traditional fuel energy. In recent years, microbial fuel cell (MFC) which can directly convert the chemical energy from organic compounds into electric energy has been developed. By using MFC, biomass energy could be directly harvested with the form of electricity, the most convenient, wide-spread, and clean energy. Therefore, MFC was considered as another promising way to harness the sustainable energies in biomass and added new dimension to the biomass energy industry. In this review, the pretreatment methods for biomass towards electricity harvesting with MFC, and the microorganisms utilized in biomass-fueled MFC were summarized. Further, strategies for improving the performance of biomass-fueled MFC as well as future perspectives were highlighted.

Palm oil mill effluent (POME) discharged without treatment into watercourses can pollute the water source. Microbial fuel cell (MFC) has gained high attention as a green technology of converting organic wastewater into bio-energy. As an approach to overcome the limitations of the existing POME treatment methods, air-cathode MFC-Adsorption system is introduced as an innovative technology to treat POME and generate bio-electricity simultaneously. However, the use of conventional MFC with proton exchange membrane in large scale applications is restricted by the high cost and low power generation. Addition of mediator in MFC is essential in order to increase the electron transfer efficiency, hence enhancing the system performance. This study therefore aims to investigate the effect of different type of mediators i.e. congo red (CR), crystal violet (CV) and methylene blue (MB) on the performance of an affordable air-cathode MFC-Adsorption system made from earthen pot with POME as the substrate. The addition of different mediators altered the pH of the MFC-Adsorption system, in which more alkaline system showed better performance. The voltage generated in the system with CR, CV and MB mediator was 120.58 mV, 168.63 mV and 189.25 mV whereas the current generated was 2.41 mA, 3.37 mA and 3.79 mA, respectively. The power density of 290.79 mW/m3, 568.72 mW/m3 and 716.31 mW/m3 was produced in the MFC-Adsorption system with CR, CV and MB mediator, respectively. The highest POME treatment efficiency was achieved in MFC-Adsorption system with MB mediator, which resulted in biochemical oxygen demand, chemical oxygen demand, total suspended solids, turbidity and ammoniacal nitrogen removal of 75.3%, 84.8%, 91.5%, 86.1% and 23.31%, respectively. Overall, the air-cathode MFC-Adsorption system with addition of MB mediator was feasible for POME treatment and simultaneous bio-energy generation.

Abstract Production of bioethanol and bioelectricity is a promising approach through microbial electrochemical technology. Sugars are metabolized by yeast to produces ethanol, CO2 and energy. Surplus electrons produced during the fermentation can be transferred through the circuit to generate electricity in a Microbial fuel cell (MFC). In the present study, a membrane less single chambered microbial fuel cell was developed for simultaneous production of bioethanol and bioelectricity. Pichia fermentans along with a well-known ethanol producing yeast Saccharomyces cerevisiae was allowed to ferment glucose. S. cerevisiae demonstrated maximum open circuit voltage (OCV) 0.287 ± 0.009 V and power density 4.473 mW m− 2 on 15th day, with a maximum ethanol yield of 5.6% (v/v) on 12th day. P. fermentans demonstrated a maximum OCV of 0.318 ± 0.0039 V and power density of 8.299 mW m− 2 on 15th day with ethanol yield of 4.7 % (v/v) on 12th day. Coulombic efficiency (CE) increased gradually from 0.002–0.471 % and 0.012–0.089 % in the case of S. cerevisiae and P. fermentans, respectively, during 15 days of experiment. Thus, the result indicated that Single chambered fuel cell can be explored for its potential applications for ethanol production along with clean energy generation.

AbstractThis project trial provides a novel small-scale solar harnessing technology which increases environmental effectiveness while maintaining optimal energy efficiency. Although modern solar panels are purposed in producing clean energy, the materials and byproducts of solar cell manufacturing are not eco-friendly. Thus, considering an organic, renewable and energy efficient solar cell model is necessary. Investigations explored multiple highly-photosynthetic algal species which were later integrated into a controlled microbial fuel cell system (MFC). The MFC1 contained algae culture species, including Chlorella Vulgaris, Nannochloropsis, and Spirulina. Parameters, such as periodic lipid yields, algal biomass, and light absorption were assessed throughout the cultivation process while maintaining a controlled environment. After 30 days of cultivation, the culture was transferred to an anode chamber in a closed loop small-scale MFC. Following the first day of algae transfer, microwatt output was analyzed from independent test trials. Statistical comparisons were drawn between electrical energy and light absorption, finding a generally positive correlation. Thus, it is concluded that mid-high algae concentrations significantly increased electrical micro-wattage in highly absorptive algal cultures. The optimal electric levels occurred at 286 A (absorbance) and 35 mW-Nannochloropsis, 123 A-Chlorella (30.2 mW), and 142 A (31 mW)-Spirulina culture. Due to higher absorption rates in the Nannochloropsis culture, this corresponds with the record high voltage levels. The analysis of data indicates that Algae-based MFCs are proven hopeful for alternative high-yield energy production.
