Photosynthetic Algal microbial fuel cell

The project demonstrated significant potential in utilizing a photosynthetic algal microbial fuel cell (PAMFC) for addressing climate change while simultaneously producing renewable energy, treating wastewater, and facilitating carbon fixation. By employing blue-green algae in the cathode chamber sourced from a local water tank, and utilizing wastewater in the anode chamber connected through a salt bridge made of sand and sodium chloride, the system effectively showcased the principles of renewable energy generation. The PAMFC system achieved a maximum output of 50 mV, 10 mA, and 0.1 mW, indicating its viability as a green energy alternative. Additionally, the fermentation observed in the wastewater chamber highlighted its effectiveness in treating wastewater over time. While the project could not measure carbon fixation due to the lack of necessary facilities and sensors, it underscored the algae’s capacity to absorb carbon dioxide comparable to trees. Overall, the project emphasized the PAMFC’s potential for sustainable energy generation and environmental remediation, offering a promising tool for future innovations in renewable energy and ecological sustainability.

Microbial Fuel Cells (MFCs) offered numerous benefits, including environmental, social, and economic spheres . Environmentally, MFCs reduced greenhouse gas emissions by converting organic waste into clean energy, which also minimised landfill waste and pollution through improved waste management, and enhanced water quality by treating wastewater. Socially, MFCs empowered communities through workshops, training, and awareness campaigns, fostering engagement, education, and valuable skill development. They also improved community health by reducing pollution. Economically, MFCs provided a sustainable energy source, reducing reliance on fossil fuels. MFCs yield significant cost savings by minimizing waste disposal expenses and reducing energy costs, making them an attractive solution for environmentally conscious and budget-sensitive organizations. By harnessing organic waste as a fuel source, MFCs decreased the financial burden of traditional energy production and waste management. Overall, MFCs served as a catalyst for holistic community development, addressing social, economic, and environmental needs while promoting a culture of innovation and sustainability.
